    Anhörig och Soldat: Soldatens motiv och anhörigas respons på beslut om internationell militär insats. Oro, saknad och längtan2018Bok (Annet vitenskapelig)
    Abstract [sv]

    Dialogisk deltagande aktionsforskning har i perioden 2012–2017 bedrivits om svenska soldater, utlandsveteraner och deras familjer. Fokus har varit relationella aspekter, hur det blir för dem som anhöriga, vilket stöd de behöver, liksom vilken kapacitet de utvecklar, när en familjemedlem åker iväg på internationell militär insats i områden med krig och terror. I studien har 110 vuxna varav 42 soldater/utlandsveteraner, 42 partners, 21 föräldrar till soldat, 10 syskon. Några deltagare har dubbel koppling, är exempelvis både veteran och partner. Dessutom har 37 barn till soldat/utlandsveteran deltagit och desto fler berättats om.

    Soldatens motivation konstrueras av soldaten i relation till och i interaktion med viktiga personer i soldatens familj, arbete och nätverk. Motivationen samskapas i något som kan ses som ett sammanflätat nätverk av önskningar och förhoppningar, förväntningar och krav som kommuniceras i interaktionen mellan personer i soldatens nätverk och flera olika kontexter som omger soldaten. Obalans i samspelet kan leda till att soldaten upplever längtan tillbaka till missionstillvarons sammanhang med förutsägbarhet i vad som förväntas av deltagarna, med arbetsuppgifter som känns meningsfulla. Utan denna värker ”missionsgiftet” och ”missionstarmen” suger hos utlandsveteranen till att delta i fler missioner.

    Familjemedlemmarna berättar om hur interaktionen inom familjen påverkats på gott och ont. Resultaten tyder på att ju mer soldaten förmår att involvera och förklara för sina anhöriga om vad som är på gång samt motivera sig själv och sina anhöriga att lyssna på och beakta varandras perspektiv, desto bättre förutsättningar för lyckad insats för såväl soldaten som de hemmavarande anhöriga. Här belyses även de känslor av saknad som de anhöriga berättar om som blir svåra att bära eftersom saknaden kombineras med oro för soldatens säkerhet och hur den egna förmågan hemmavid ska räcka till om något oönskat skulle hända. Avgörande I alla skeden och faser vid anhörigs deltagande i internationell militär insats, är att de anhöriga har goda förutsättningar och kommunikationsmedel för att kunna kommunicera som familj i relation till varandra. De känslor av saknad som de anhöriga berättar om, blir svåra att bära eftersom saknaden kombineras med oro för soldatens säkerhet och hur den egna förmågan hemmavid ska räcka till om något oönskat skulle hända. Tillsammans med familjerna behöver det militära systemet göra anpassningar och utveckla lösningar som gör att kombinationen arbete – familj underlättas för de försvarsanställda då de förväntas kunna utöva föräldraskap och anhörigskap på distans. Par och familjer kan komma att ha svårt att hålla isär vad som handlar om de yttre förhållandena och vad som handlar om deras inre processer och relationer. Detta kan förebyggas genom:

    1)     Att det militära systemet underlättar för soldaterna att upprätthålla relationell kontakt med sina anhöriga inklusive att underlätta att det kan ske på ett integritetsäkert sätt såväl under förberedelsetiden som under insatstiden.

    2)     att anhöriga tidigt informeras och erbjuds att bli insatta i vad den militära insatsen innebär och varför den görs; i vilka insatsförhållandena, inklusive arbets- och levnadsvillkor som väntar soldaten; vad som kan utvecklas under insatsen inklusive egna responser och de som kommer från andra i omgivningen. Tips kan ges om hur dessa kan förebyggas eller mötas.

    3)     att soldaten uppmuntras och erbjuds stöd i att förbereda och samtala med sina anhöriga i god tid före insats samt fortsättningsvis vid behov under och efter insats. Detta kan ske genom att närmaste befäl håller sig underrättad om utvecklingen därhemma för varje enskild underställd soldat i samband med internationell militär insats.

    One-carbon metabolism biomarkers and genetic variants in relation to colorectal cancer risk by KRAS and BRAF mutation status2018Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, nr 4, artikkel-id e0196233Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Disturbances in one-carbon metabolism, intracellular reactions involved in nucleotide synthesis and methylation, likely increase the risk of colorectal cancer (CRC). However, results have been inconsistent. To explore whether this inconsistency could be explained by intertumoral heterogeneity, we evaluated a comprehensive panel of one-carbon metabolism biomarkers and some single nucleotide polymorphisms (SNPs) in relation to the risk of molecular subtypes of CRC defined by mutations in the KRAS and BRAF oncogenes. This nested case-control study included 488 CRC cases and 947 matched controls from two population-based cohorts in the Northern Sweden Health and Disease Study. We analyzed 14 biomarkers and 17 SNPs in prediagnostic blood and determined KRAS and BRAF mutation status in tumor tissue. In a multivariate network analysis, no variable displayed a strong association with the risk of specific CRC subtypes. A non-synonymous SNP in the CTH gene, rs1021737, had a stronger association compared with other variables. In subsequent univariate analyses, participants with variant rs1021737 genotype had a decreased risk of KRAS-mutated CRC (OR per allele = 0.72, 95% CI = 0.50, 1.05), and an increased risk of BRAF-mutated CRC (OR per allele = 1.56, 95% CI = 1.07, 2.30), with weak evidence for heterogeneity (Pheterogeneity = 0.01). This subtype-specific SNP association was not replicated in a case-case analysis of 533 CRC cases from The Cancer Genome Atlas (P = 0.85). In conclusion, we found no support for clear subtype-specific roles of one-carbon metabolism biomarkers and SNPs in CRC development, making differences in CRC molecular subtype distributions an unlikely explanation for the varying results on the role of one-carbon metabolism in CRC development across previous studies. Further investigation of the CTH gene in colorectal carcinogenesis with regards to KRAS and BRAF mutations or other molecular characteristics of the tumor may be warranted.

    Critical domain interactions for type A RNase P RNA catalysis with and without the specificity domain2018Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, nr 3, artikkel-id e0192873Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The natural trans-acting ribozyme RNase P RNA (RPR) is composed of two domains in which the catalytic (C-) domain mediates cleavage of various substrates. The C-domain alone, after removal of the second specificity (S-) domain, catalyzes this reaction as well, albeit with reduced efficiency. Here we provide experimental evidence indicating that efficient cleavage mediated by the Escherichia coli C-domain (Eco CP RPR) with and without the C5 protein likely depends on an interaction referred to as the "P6-mimic". Moreover, the P18 helix connects the C-and S-domains between its loop and the P8 helix in the S-domain (the P8/P18-interaction). In contrast to the "P6-mimic", the presence of P18 does not contribute to the catalytic performance by the C-domain lacking the S-domain in cleavage of an all ribo model hairpin loop substrate while deletion or disruption of the P8/P18-interaction in full-size RPR lowers the catalytic efficiency in cleavage of the same model hairpin loop substrate in keeping with previously reported data using precursor tRNAs. Consistent with that P18 is not required for cleavage mediated by the C-domain we show that the archaeal Pyrococcus furiosus RPR C-domain, which lacks the P18 helix, is catalytically active in trans without the S-domain and any protein. Our data also suggest that the S-domain has a larger impact on catalysis for E. coli RPR compared to P. furiosus RPR. Finally, we provide data indicating that the absence of the S-domain and P18, or the P8/P18-interaction in full-length RPR influences the charge distribution near the cleavage site in the RPR-substrate complex to a small but reproducible extent.

    A review of Swedish crop residue statistics used in the greenhouse gas inventory2005Rapport (Annet vitenskapelig)
    Abstract [en]

    The IPCC (Intergovernmental Panel on Climate Change) calculation model for nitrous oxide (N2O) emissions from agricultural land includes emissions from the nitrogen turnover in crop residues. The nitrogen content of crop residues is calculated using primary crop statistics in combination with recalculation factors, that is, the ratios of crop residue/primary crop and the nitrogen content in crop residues. In addition, information on removed crop residues is used to subtract that part of the crop residues that is not turned over on agricultural land.

    A comparison between data used in different countries reveals great differences.1 Variations in climate, soil fertility and production methods across different countries partly explain some of the differences. Nevertheless, it is likely that these differences also depend on different definitions as well as on variations in the trial data. A more systematic comparison of the recalculations for different countries requires well-documented sources of information

    A synbiotic-containing amino-acid-based formula improves gut microbiota in non-IgE-mediated allergic infants2018Inngår i: Pediatric Research, ISSN 0031-3998, E-ISSN 1530-0447, Vol. 83, nr 3, s. 677-686Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Prebiotics and probiotics (synbiotics) can modify gut microbiota and have potential in allergy management when combined with amino-acid-based formula (AAF) for infants with cow’s milk allergy (CMA).

    Methods: This multicenter, double-blind, randomized controlled trial investigated the effects of an AAF-including synbiotic blend on percentages of bifidobacteria and Eubacterium rectale/Clostridium coccoides group (ER/CC) in feces from infants with suspected non-IgE-mediated CMA. Feces from age-matched healthy breastfed infants were used as reference (healthy breastfed reference (HBR)) for primary outcomes. The CMA subjects were randomized and received test or control formula for 8 weeks. Test formula was a hypoallergenic, nutritionally complete AAF including a prebiotic blend of fructo-oligosaccharides and the probiotic strain Bifidobacterium breve M-16V. Control formula was AAF without synbiotics.

    Results: A total of 35 (test) and 36 (control) subjects were randomized; HBR included 51 infants. At week 8, the median percentage of bifidobacteria was higher in the test group than in the control group (35.4% vs. 9.7%, respectively; P<0.001), whereas ER/CC was lower (9.5% vs. 24.2%, respectively; P<0.001). HBR levels of bifidobacteria and ER/CC were 55% and 6.5%, respectively.

    Conclusion: AAF including specific synbiotics, which results in levels of bifidobacteria and ER/CC approximating levels in the HBR group, improves the fecal microbiota of infants with suspected non-IgE-mediated CMA.

    Clinical Cell Therapy Guidelines for Neurorestoration (IANR/CANR 2017)2018Inngår i: Cell Transplantation, ISSN 0963-6897, E-ISSN 1555-3892, Vol. 27, nr 2, s. 310-324Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Cell therapy has been shown to be a key clinical therapeutic option for central nervous system diseases or damage. Standardization of clinical cell therapy procedures is an important task for professional associations devoted to cell therapy. The Chinese Branch of the International Association of Neurorestoratology (IANR) completed the first set of guidelines governing the clinical application of neurorestoration in 2011. The IANR and the Chinese Association of Neurorestoratology (CANR) collaborated to propose the current version "Clinical Cell Therapy Guidelines for Neurorestoration (IANR/CANR 2017)". The IANR council board members and CANR committee members approved this proposal on September 1, 2016, and recommend it to clinical practitioners of cellular therapy. These guidelines include items of cell type nomenclature, cell quality control, minimal suggested cell doses, patient-informed consent, indications for undergoing cell therapy, contraindications for undergoing cell therapy, documentation of procedure and therapy, safety evaluation, efficacy evaluation, policy of repeated treatments, do not charge patients for unproven therapies, basic principles of cell therapy, and publishing responsibility.

    Översyn av läckagekoefficienter2012Rapport (Annet vitenskapelig)
    Abstract [sv]

    I samband med retentionsberäkningar i vissa avrinningsområden med åker på ler-jordar har problem uppstått med låga bruttobelastningar. Detta skulle kunna bero på för låga kvävehalter för lerjordar som använts som indata. En översyn har därför utförts av de beräknade kväveläckagekoefficienterna för jordbruksmark för styv lera (clay) från TRK och PLC5.

    För att kunna jämföra utveckling och förändringar av metoden för beräkningar av läckagekoefficienterna (NLeCCS) mellan TRK och PLC5 har beräkningar för år 1999 utförda inom ramen för TRK projektet jämförts med senare utförda beräk-ningar för 1999 med PLC5-metoden. För att utvärdera hur förändringarna mellan de två metoderna påverkat utlakningen från lerjordarna har beräkningen för 1999 med PLC5-metoden använts som utgångspunkt och manipulerats för att utvärdera enskilda förändringar mellan de två metoderna. Effekten av förändringar av rotdjup för clay, ändrad klimatperiod (och målavrinning), ogräsupptag, vallinsådd, vårbe-arbetning, rotdjup för träda och halt organiskt material i marken beräknades. För-ändringen av rotdjup för vissa grödor påverkade bara beräkningen för clay medan de övriga förändringarna som testats även påverkade beräkningen för de övriga jordarna. Förändringen av rotdjupet av vissa grödor ökade koncentrationen för clay i alla regioner och ändrad klimatperiod gav både ökade och minskade koncentrat-ioner i regionerna. I region 4 och 6 gav ändrat rotdjup för clay och ändrad klimat-period ungefär samma koncentration med PLC5-metoden som med TRK-metoden.

    En genomgång av uppmätta kvävehalter från rutförsök, observationsfält och ty-pområden på jordbruksmark som domineras av styv lera har gjorts. I dessa områ-den varierade långtidsmedelvärdena mellan 3,3 och 5,3 mg NO3-N/l. I motsva-rande regioner (4, 5a och 6) var de beräknade koncentrationerna i TRK i samma storleksordning, medan koncentrationerna beräknade med PLC5-metodiken var något lägre.

    Med FyrisNP simulerades N-transport från ett avrinningsområde dominerat av styv lera med användning av läckagekoefficienter (PLC5-metodik), lokal grödfördel-ning och förbättrad jordartskarta. Simuleringarna kunde inte uppnå uppmätta N-koncentrationer i utloppspunkten för område U8 (Figur 27), varken med koeffici-enterna från TRK eller PLC5 med regional eller lokal grödfördelning. Den bästa överenskommelsen med uppmätta värden nåddes då läckagekoefficienterna från PLC5 räknades upp 2,5 gång.

    Global analysis of A-to-I RNA editing reveals association with common disease variants2018Inngår i: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 6, artikkel-id e4466Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    RNA editing modifies transcripts and may alter their regulation or function. In humans, the most common modification is adenosine to inosine (A-to-I). We examined the global characteristics of RNA editing in 4,301 human tissue samples. More than 1.6 million A-to-I edits were identified in 62% of all protein-coding transcripts. mRNA recoding was extremely rare; only 11 novel recoding sites were uncovered. Thirty single nucleotide polymorphisms from genome-wide association studies were associated with RNA editing; one that influences type 2 diabetes (rs2028299) was associated with editing in ARPIN. Twenty-five genes, including LRP11 and PLIN5, had editing sites that were associated with plasma lipid levels. Our findings provide new insights into the genetic regulation of RNA editing and establish a rich catalogue for further exploration of this process.

    Subgrain-controlled grain growth in the laser-melted 316 L promoting strength at high temperatures2018Inngår i: Royal Society Open Science, E-ISSN 2054-5703, Vol. 5, nr 5, artikkel-id 172394Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Stainless steel 316 L prepared by laser melting consisted of a hierarchical austenitic microstructure with micrometresized (10–25 µm) grains containing fine 1 µm subgrains with a cellular structure. At high-temperature thermal treatments (greater than or equal to 1100°C), merging and growth of the 1 µm subgrains into bigger subgrains restricted the rapid grain growth and microstructure coarsening. Partial phase transformation of austenite to ferrite at temperatures greater than or equal to 1100°C, in combination with gradual and steady growth of subgrains inside the micrometre-sized grains and nucleation of the sigma phase, has promoted the tensile strength of stainless steel 316 L to 300 MPa at 1100°C compared with that of conventionally made 316 L counterparts (approx. 40 MPa). The grain growth mechanism of the laser-melted microstructure can change the application criteria for 316 L and expand the application fields for 316 L.

    Förbättrad beräkningsmetodik för retention av fosfor från enskilda avlopp Slutrapport2009Rapport (Annet vitenskapelig)
    Abstract [sv]

    Inom projektet Förbättrad beräkningsmetodik för retention av fosfor från enskilda avlopp har SMED utvärderat den teoretiska metodiken för att beräkna bruttobelastning av fosfor och kväve från enskilda avlopp genom mätningar i området Garns-Ekskogen i Vallentuna kommun. Vissa förfiningar av beräkningsmetodiken har också utvecklats och implementerats i projektet.

    Med dessa förbättringar kan konstateras att den teoretiska fosforbelastningen från enskilda avlopp ligger nära den som bestämts via beräkningar utgående från mätningar. Den teoretiska fosforbelastningen är 1-2 gånger så hög som den utifrån mätningar beräknade belastningen, vilket är rimligt med tanke på osäkerheten i mätningarna och i indata till de teoretiska beräkningarna. Bakgrundsbelastningen från omgivande skogsmark är enligt enkla läckageberäkningar låg jämfört med den från enskilda avlopp i detta område.

    För kväve gäller det omvända, då den teoretiska belastningen från enskilda avlopp är tre gånger lägre än den som kan beräknas utifrån mätningar, vilket är förklarligt då belastningen från andra källor för kväve är betydligt högre än för fosfor.

    Markretentionens bidrag till skillnaden mellan beräknad och genom mätningar framtagen belastning har inte kunna säkerställas pga den stora osäkerheten som finns kring reningsschabloner och andra felkällor. En grov uppskattning ger dock att markretentionen för fosfor från enskilda avlopp i projektområdet är runt 50%.

    SMEDs belastningsberäkningar för enskilda avlopp bör i första hand förbättras genom att den uppdaterade beräkningsmetodiken appliceras nationellt. Vad gäller belastningsdata är detta inget problem, då SCB redan har tillgång till denna statistik. För att förbättra belastningsstatistiken är det även nödvändigt att teknikuppgifterna för enskilda avlopp uppdateras och att i denna datainsamling reningsteknik för BDT- och WC-vatten separeras så att beräkningarna kan hantera både ”tvårörssystem” och fastigheter med enbart BDT-avlopp.

    Slowly progressive dementia caused by MAPT R406W mutations: longitudinal report on a new kindred and systematic review2018Inngår i: Alzheimer's Research & Therapy, ISSN 0065-6755, E-ISSN 1758-9193, Vol. 10, artikkel-id 2Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Background: The MAPT c.1216C > T (p.Arg406Trp; R406W) mutation is a known cause of frontotemporal dementia with Parkinsonism linked to chromosome 17 tau with Alzheimer's disease-like clinical features. Methods: We compiled clinical data from a new Swedish kindred with R406W mutation. Seven family members were followed longitudinally for up to 22 years. Radiological examinations were performed in six family members and neuropathological examinations in three. We systematically reviewed the literature and compiled clinical, radiological, and neuropathological data on 63 previously described R406W heterozygotes and 3 homozygotes. Results: For all cases combined, the median age of onset was 56 years and the median disease duration was 13 years. Memory impairment was the most frequent symptom, behavioral disturbance and language impairment were less common, and Parkinsonism was rare. Disease progression was most often slow. The most frequent clinical diagnosis was Alzheimer's disease. R406W homozygotes had an earlier age at onset and a higher frequency of behavioral symptoms and Parkinsonism than heterozygotes. In the new Swedish kindred, a consistent imaging finding was ventromedial temporal lobe atrophy, which was evident also in early disease stages as a widening of the collateral sulcus with ensuing atrophy of the parahippocampal gyrus. Unlike previously published R406W carriers, all three autopsied patients from the novel family showed neuropathological similarities with progressive supranuclear palsy, with predominant four-repeat (exon 10+) tau isoform (4R) tauopathy and neurofibrillary tangles accentuated in the basal-medial temporal lobe. Amyloid-beta pathology was absent. Conclusions: Dominance of 4R over three-repeat (exon 10-) tau isoforms contrasts with earlier reports of R406W patients and was not sufficiently explained by the presence of H1/H2 haplotypes in two of the autopsied patients. R406W patients often show a long course of disease with marked memory deficits. Both our neuropathological results and our imaging findings revealed that the ventromedial temporal lobes were extensively affected in the disease. We suggest that this area may represent the point of origin of tau deposition in this disease with relatively isolated tauopathy.

    Förbättrad markanvändningsdata för beräkningar inom SMED Vatten2010Rapport (Annet vitenskapelig)
    Abstract [sv]

    Projektets huvudsyfte är att generera nya geografiska dataunderlag avseende markanvändning med bättre upplösning för beräkningar inom SMED Vatten och att undersöka konsekvenserna för kommande rapporteringar av att använda markanvändningsdata med högre rumslig- och tematisk upplösning.

    Underlaget till arbetet som genomförts i projektet är dels det tidigare markanvändningsunderlaget som använts inom SMED Vatten för beräkningar av belastningar till vatten tillsammans med ett nyframtaget underlag för markanvändningsdata som bygger på SMD (Svenska Marktäckedata). Båda markanvändningsdatabaserna relateras till den geografiska indelningen som utgörs av hydrologiskt beräknade delavrinningsområden. Underlaget har lästs in i geodatabaser där data relateras till varandra genom rumsliga beräkningar i ett geografiskt informationssystem.

    För klasserna skog och tätort överskattas arealen generellt i PLC5 data jämfört med SMD och för klasserna myr och vatten sker en underskattning av klassarealerna i PLC5 jämfört med SMD. Minsta arealskillnaden blir på klassen vatten som också uppvisar den minsta standardavvikelsen.

    Konsekvensen av att byta kartdatabas för beräkning av markanvändningsarealer är liten vid en total jämförelse mellan markanvändning i PLC5 beräkningarna jämfört med arealer hämtade ur SMD. Orsaken till detta är att arealerna hos de områden som står för en stor andel av bruttobelastningen är desamma i de båda underlagen. För enskilda delavrinningsområden kan förändringen vara stor.

    Beräkningstekniskt eller kostnadsmässigt finns det inga skäl att använda SMD som kartdatabas för att generera markanvändningsklassning för belastningsberäkningar i SMED Vatten. Det finns ingen anledning att byta ut den gamla klassningen med avseende på geografisk upplösning då förbättringen med att använda SMD är alltför marginell i jämförelse med andra osäkerheter och felkällor. Däremot är det troligt att belastningen kommer att förändras om lämpliga läckagehalter kan ansättas till fler klasser och den vägen öka noggrannheten i belastningen av kväve och fosfor.

    Sensorimotor Robot Policy Training using Reinforcement Learning2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Robots are becoming more ubiquitous in our society and taking over many tasks that were previously considered as human hallmarks. Many of these tasks, e.g., autonomously driving a car, collaborating with humans in dynamic and changing working conditions and performing household chores, require human-level intelligence to perceive the world and to act appropriately. In this thesis, we pursue a different approach compared to classical methods that often construct a robot controller based on the perception-then-action paradigm. We devise robotic action-selection policies by considering action-selection and perception processes as being intertwined, emphasizing that perception comes prior to action and action is key to perception. The main hypothesis is that complex robotic behaviors come as the result of mastering sensorimotor contingencies (SMCs), i.e., regularities between motor actions and associated changes in sensory observations, where SMCs can be seen as building blocks to skillful behaviors. We elaborate and investigate this hypothesis by deliberate design of frameworks which enable policy training merely based on data experienced by a robot,without intervention of human experts for analytical modelings or calibrations. In such circumstances, action policies can be obtained by reinforcement learning (RL) paradigm by making exploratory action decisions and reinforcing patterns of SMCs that lead to reward events for a given task. However, the dimensionality of sensorimotor spaces, complex dynamics of physical tasks, sparseness of reward events, limited amount of data from real-robot experiments, ambiguities of crediting past decisions and safety issues, which arise from exploratory actions of a physical robot, pose challenges to obtain a policy based on data-driven methods alone. In this thesis, we introduce our contributions to deal with the aforementioned issues by devising learning frameworks which endow a robot with the ability to integrate sensorimotor data to obtain action-selection policies. The effectiveness of the proposed frameworks is demonstrated by evaluating the methods on a number of real robotic tasks and illustrating the suitability of the methods to acquire different skills, to make sequential action-decisions in high-dimensional sensorimotor spaces, with limited data and sparse rewards.

    Combinatorics and topology related to involutions in Coxeter groups2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This dissertation consists of three papers in combinatorial Coxeter group theory.

    A Coxeter group is a group W generated by a set S, where all relations can be derived from the relations s2 = e for all s 𝜖 S, and (ss)m(s,s) = e for some pairs of generators s s in S, where e 𝜖 W is the identity element and m(s, s) is an integer satisfying that m(s, s) = m(s, s) ≥ 2. Two prominent examples of Coxeter groups are provided by the symmetric group Sn (i.e., the set of permutations of {1, 2, . . . , n}) and finite reflection groups (i.e., finite groups generated by reflections in some real euclidean space). There are also important infinite Coxeter groups, e.g., affine reflection groups.

    Every Coxeter group can be equipped with various natural partial orders, the most important of which is the Bruhat order. Any subset of a Coxeter group can then be viewed as an induced subposet.

    In Paper A, we study certain posets of this kind, namely, unions of conjugacy classes of involutions in the symmetric group. We obtain a complete classification of the posets that are pure (i.e., all maximal chains have the same length). In particular, we prove that the set of involutions with exactly one fixed point is pure, which settles a conjecture of Hultman in the affirmative. When the posets are pure, we give their rank functions. We also give a short, new proof of the EL-shellability of the set of fixed-point-free involutions, established by Can, Cherniavsky, and Twelbeck.

    Paper B also deals with involutions in Coxeter groups. Given an involutive automorphism θ of a Coxeter system (W, S), let

    ℑ(θ) = {w 𝜖 W | θ(w) = w−1}

    be the set of twisted involutions. In particular, ℑ(id) is the set of ordinary involutions in W. It is known that twisted involutions can be represented by words in the alphabet  = { | s 𝜖 S}, called -expressions. If ss has finite order m(s, s), let a braid move be the replacement of  by ⋯, both consisting of m(s, s) letters. We prove a word property for ℑ(θ), for any Coxeter system (W, S) with any θ. More precisely, we provide a minimal set of moves, easily determined from the Coxeter graph of (W, S), that can be added to the braid moves in order to connect all reduced -expressions for any given w 𝜖 ℑ(θ). This improves upon a result of Hamaker, Marberg, and Pawlowski, and generalises similar statements valid in certain types due to Hu, Zhang, Wu, and Marberg.

    In Paper C, we investigate the topology of (the order complexes of) certain posets, called pircons. A special partial matching (SPM) on a poset is a matching of the Hasse diagram satisfying certain extra conditions. An SPM without fixed points is precisely a special matching as defined by Brenti. Let a pircon be a poset in which every non-trivial principal order ideal is finite and admits an SPM. Thus pircons generalise Marietti’s zircons. Our main result is that every open interval in a pircon is a PL ball or a PL sphere.

    An important subset of ℑ(θ) is the set 𝜄(θ) = {θ(w−1)w | w 𝜖 W} of twisted identities. We prove that if θ does not flip any edges with odd labels in the Coxeter graph, then 𝜄(θ), with the order induced by the Bruhat order on W, is a pircon. Hence, its open intervals are PL balls or spheres, which confirms a conjecture of Hultman. It is also demonstrated that Bruhat orders on Rains and Vazirani’s quasiparabolic W-sets (under a boundedness assumption) form pircons. In particular, this applies to all parabolic quotients of Coxeter groups.

    Hemicelluloses and other Polysaccharides for Wood Adhesive Applications2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The growing environmental awareness has led to an increased interest in bio-based polymers as replacement for fossil-based materials. The purpose of the work described in this thesis was to investigate the possibility of using hemicelluloses and other polysaccharides as replacement for fossil-based polymers in wood adhesives. Together with cellulose and lignin, hemicellulose is the main constituent of wood. In the pulp industry, significant amounts of hemicelluloses are obtained as by-products and combusted for energy recovery, but there is a growing interest in the biorefinery concept where all side-streams are utilized. If valuable applications, such as adhesives, of hemicelluloses and other by-products are found, large amounts can be obtained from the pulp industry. Water dispersions of hemicelluloses and other polysaccharides have been prepared and evaluated as adhesives for bonding different wood substrates together. The dry bond strength, water resistance, and heat resistance were investigated by exposing the bonded wood specimens to different conditioning methods and thereafter measuring the tensile shear strengths. As a replacement, the bio-based wood adhesive must possess similar or even better properties than the fossil-based adhesives. A commercial poly(vinyl acetate) (PVAc) wood adhesive used for indoor applications has been used as a reference benchmark. Wood hemicelluloses themselves do not have sufficient bonding performance probably because their low molecular weight does not provide adequate strength and makes the adhesive too brittle. The addition of dispersing agents and crosslinkers to the hemicellulose dispersions can significantly improve the bonding performance, and hemicellulose in combination with poly(vinyl amine) showed promising results superior those of PVAc. A fully bio-based adhesive comprising of hemicellulose and chitosan, another bio-based polysaccharide, obtain surprisingly good bonding performance especially with regard to water resistance. Gums, polysaccharides with similar structures to those of hemicelluloses but with higher molecular weights, have also been studied and locust bean gum dispersions without any modification showed a very good bonding performance with high dry bond strength and water resistance on a par with those of PVAc and a heat resistance superior to that of PVAc. Chitosan has very good adhesive properties especially with regard to water resistance, but the high viscosity of the chitosan dispersion makes it difficult to apply. Chitosan-grafted-PVAc dispersions were therefore prepared and an adhesive very similar in appearance to PVAc was obtained with a good bonding performance as well as good applicability.

    Skolerfarenheter och självskattad hälsa bland elever i särskolan2018Rapport (Fagfellevurdert)
    Abstract [sv]

    Särskolan är en skolform för elever med intellektuella funktionsnedsättningar. Forskning visar att elever i särskolan, trots olika insatser från olika aktörer, inte erbjuds full delaktighet i samhället. En god förståelse för dessa elevers skolgång är därför viktig för att arbeta för de ska få en så tillfredställande livssituation som möjligt. Syftet med projektet var att få ökad kunskap om vilka samband som finns mellan elevernas socioekonomiska bakgrund, sociodemografiska förhållanden, upplevelse av skolsituation samt deras egna skattningar av hälsa. Särskoleelevernas svar jämförs även med svar från elever i övrig skola. Data bygger på enkätundersökningar som genomförts bland 1320 särskoleelever i högstadium och gymnasium i olika kommuner åren 2003-2015. En jämförelse görs även mellan elever i särskolan och elever i övriga skolan i Stockholm för åren 2013-2015.

    Tre frågor har formulerats: Hur upplever elever i grundsärskolan och gymnasiesärskolan sin skolsituation och hälsa? Vilka samband finns mellan särskoleelevernas socio-ekonomiska bakgrund, sociodemografiska förhållanden, upplevelse av skolsituation samt deras självskattade hälsa och egenrapporterade hälsobesvär. Finns det några skillnader mellan elever i särskolan och övrig skola avseende skolsituation och hälsa? Data visar att:

    • Ungefär hälften av eleverna i särskolan skattar sin hälsa som mycket bra, ca 10 % anser att den är dålig.
    • Majoriteten särskoleelever upplever skolklimatet som positivt med goda möjligheter till inlärning.
    • Mer än hälften av eleverna i särskolan har förtroende för lärare
    • För självskattad hälsa framträder inga signifikanta samband med utländsk bakgrund. Bland särskoleelever på högstadiet är psykiska besvär mindre vanliga bland invandrarungdomar. Elever i särskolan med utländsk bakgrund är överrepresenterade jämfört med motsvarande andel i grundskolan och gymnasieskolan.
    • Resultaten visar att kön spelar roll. Ser vi till olika uppskattade hälsobesvär gäller genomgående att dessa är vanligare bland flickor. Detta gäller både särskola och övrig skola.
    • Förtroende för föräldrar och skoltrivsel kan kopplas samman med självskattad hälsa både bland elever i särskolan och bland elever i övriga skolan. Ungdomar som har förtroende för föräldrar skattar sin hälsa högre. För skoltrivsel följer sambandet i huvudsak ett mönster där bättre skoltrivsel kopplas till bättre självskattad hälsa.
    • Bland elever på högstadiet i övriga skolan finns en koppling till familjesituation och socioekonomisk bakgrund. Ungdomar som bor hos båda föräldrar eller har växelvis boende redovisar lägre förekomst av psykiska besvär än ungdomar i andra boenden.
    • Bland eleverna i gymnasiesärskolan framträder ett klart samband med förtroende för lärare. De som inte angett att de har förtroende för lärare redovisar högre förekomst av besvär.

    Det finns några skillnader mellan elever i särskolan och övrig skola avseende skolsituation och hälsa, men de grundläggande dragen är desamma. Sammantaget tyder resultaten på att det är samma faktorer som påverkar hälsa bland elever i särskolan och i övriga skolan. Det centrala är om eleverna har förtroende för sina föräldrar och hur de trivs i skolan.

    Heavy charged scalars from cs̄ fusion: a generic search strategy applied to a 3HDM with U(1) x U(1) family symmetry2018Inngår i: Journal of High Energy Physics (JHEP), ISSN 1126-6708, E-ISSN 1029-8479, nr 3, artikkel-id 024Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We describe a class of three Higgs doublet models (3HDMs) with a softly broken U(1) x U(1) family symmetry that enforces a Cabibbo-like quark mixing while forbidding tree-level flavour changing neutral currents. The hierarchy in the observed quark masses is partly explained by a softer hierarchy in the vacuum expectation values of the three Higgs doublets. As a consequence, the physical scalar spectrum contains a Standard Model (SM) like Higgs boson h(125) while exotic scalars couple the strongest to the second quark family, leading to rather unconventional discovery channels that could be probed at the Large Hadron Collider. In particular, we describe a search strategy for the lightest charged Higgs boson H-+/-, through the process c -> H+ -> W+ h(125), using a multivariate analysis that leads to an excellent discriminatory power against the SM background. Although the analysis is applied to the proposed class of 3HDMs, we employ a model-independent formulation such that it can be applied to any other model with the same discovery channel.

    Measurement of e+e−→π0π0ψ(3686) at √s from 4.009 to 4.600 GeV and observation of a neutral charmoniumlike structure2018Inngår i: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 97, nr 5, artikkel-id 052001Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Using ethorne-collision data collected with the BESIII detector at the BEPCII collider corresponding to an integrated luminosity of 5.2 fb(-1) at center-of-mass energies (root s) from 4.009 to 4.600 GeV, the process e(+)e(-) -> pi(0)pi(0)psi(3686) is studied for the first time. The corresponding Born cross sections are measured and found to be half of those of the reaction e(+)e(-) -> pi(0)pi(0)psi(3686). This is consistent with the expectation from isospin symmetry. Furthermore, the Dalitz plots for pi(0)pi(0)psi(3686) are accordant with those of pi(0)pi(0)psi(3686) at all energy points, and a neutral analog to the structure in pi(+/-)psi(3686) around 4040 MeV/c(2) first observed at root s = 4.416 GeV is observed in the isospin neutral mode at the same energy.

    Hantering av kopplingen mellan markanvändning, läckagekoefficienter och avrinning för PLC62013Rapport (Annet vitenskapelig)
    Abstract [sv]

    Havs- och vattenmyndigheten har uppdragit åt SMED att beräkna näringsämnesbelastningen till Sveriges omgivande havsbassänger. Uppdraget utgör underlag till HELCOM-rapporteringen Pollution Load Compilation (PLC Periodical).

    Inom SMED sker en kontinuerlig utveckling av metoder och modeller för att förbättra kvalitén på dessa beräkningar. I denna rapport undersöks möjligheterna att kombinera tidigare framtagen metodik för att beräkna källfördelningen av kväve och fosfor med ny förbättrad beräkning av avrinning genom att utnyttja en redan kalibrerad högupplöst hydrologisk modell för Sverige, kallad S-HYPE.

    Den belastning som avses i denna rapport är det diffusa markläckaget som genereras av olika slags markanvändning, beräknat som en produkt av markanvändningsslag och specifik typhalt. S-HYPE har kalibrerats med en definition av markanvändning som skiljer sig från den markanvändning som använts tidigare. För att det ska vara möjligt att använda de typhalter som  tagits fram i tidigare beräkningar behöver de olika definitionerna av markanvändning relateras till varandra. För test och validering av den nya avrinningsberäkningen genom en anpassning av tidigare kalibrerad S-HYPE till SMED – HYPE bedöms skillnader i arealer hos markanvändningen ha en försumbar effekt. För en fullständig beräkning av närsaltsläckage behöver markanvändning däremot harmoniseras.

    Data om jordbrukets arealer tas i PLC-beräkningarna från jordbruksblocken och de stödsökta grödorna. I PLC6 ändras metodiken för jordbruksblock som saknar stödsökta grödor så att dessa beräknas som odefinierade grödor med läckaget för extensiv vall, istället för att de klassas som öppen mark som i PLC5. Om möjligt ska de konstaterade grödarealerna istället för de mer preliminära stödsökta arealerna användas

    Abstract [en]

    Mobile Augmented Reality (MAR) is gaining a strong momentum to become a major interactive technology that can be applied across domains and purposes. The rapid proliferation of MAR applications in global mobile application markets has been fueled by a range of freely-available MAR software development kits and content development tools, some of which enable the creation of MAR applications even without programming skills. Despite the recent advances of MAR technology and tools, there are still many challenges associated with MAR from the User Experience (UX) design perspective. In this study, we first define UX as the emotions that the user encounters while using a service, a product or an application and then explore the recent research on the topic. We present two case studies, a commercial MAR experience and our own Virtual Campus Tour MAR application, and evaluate them from the UX perspective, with a focus on emotions. Next, we synthesize the findings from previous research and the results of the case study evaluations to form sets of challenges, opportunities and best practices related to UX design of MAR applications. Based on the identified best practices, we finally present an updated version of the Virtual Campus Tour. The results can be used for improving UX design of future MAR applications, thus making them emotionally engaging.

    Utvärdering av hastighetsmätningar med blåtandssensorer: jämförelse med data från MCS (Motorway Control System)2018Rapport (Annet vitenskapelig)
    Abstract [sv]

    Syftet med det här projektet har varit att utvärdera hur väl hastighetsmätningar som beräknats med hjälp av data från blåtandssensorer stämmer överens med radarmätningar. Av speciellt intresse har varit att utvärdera om metoden skulle kunna användas vid före-efter studier av trafiksäkerhetsåtgärder som till exempel trafiksäkerhetskameror eller andra hastighetsdämpande åtgärder. Utvärderingen baseras på data från två mätplatser på E4:an strax norr om Stockholm.

    Resultaten från studien visar att:

    • Penetrationsgraden (andel blåtandspassager per passerat fordon) varierar mellan 12 och 16 procent beroende på plats och om det är vardag eller helg.

    • Blåtandsmätningarna ger stabila resultat med avseende på medelhastigheten på dygnsnivå. Jämförelser med MCS-data visar att resultaten från de två mätmetoderna följer varandra väl och differensen mellan metoderna är ungefär lika stor från dygn till dygn.

    • Hastighetsmätningar med blåtandssensorer bedöms vara tillräckligt tillförlitliga, på den studerade vägtypen, för att kunna användas i utvärderingar av olika trafiksäkerhetsåtgärder.

    Asthma and Rhinitis among Adults in Sweden and China: Risk Factors in the Home Environment2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The main aim of this thesis was to evaluate associations between selected home environment factors and asthma, rhinitis and respiratory symptoms among adults from Sweden, China and northern Europe. Two studies were performed in Sweden, one in China, and one longitudinal cohort study was performed in northern Europe. Dampness/mould was common, and was a main risk factor in all studies. Other risk factors for asthma symptoms in Sweden included window pane condensation in winter, multi-family buildings constructed from 1961-1975, rented apartments, environment tobacco smoke (ETS), and living in a colder climate zone. Higher ventilation flow in Sweden was associated with less asthma symptoms. Risk factors for rhinitis in Sweden included window pane condensation, a higher moisture load, concrete slab foundation constructed before 1991, multi-family buildings constructed from 1976-1985, rented apartments and living in densely populated areas. Risk factors for rhinitis in China included window pane condensation, recent redecoration, new furniture, presence of cockroaches, pet keeping, ETS and living near a main road or highway. Frequently cleaning of the home and putting beddings to sunshine were protective factors for rhinitis in China. Other risk factors for respiratory infections in Sweden included houses with a brick façade, window pane condensation, a higher moisture load, multi-family buildings constructed from 1976-1985, rented apartments and living in densely populated areas. Furthermore, dampness and mould, and mould odour were risk factors for onset of asthma and rhinitis in northern Europe. In conclusion, indoor dampness and mould can be a risk factor for asthma and rhinitis in Sweden, China and northern Europe. Certain construction years (1961-1985), ETS, recent redecoration, new furniture, living in urban areas and exposure to traffic air pollution can be risk factors for asthma, rhinitis or respiratory infections. A high ventilation flow and daily cleaning at home can be protective.

    Secular trend, seasonality and effects of a community-based intervention on neonatal mortality: follow-up of a cluster-randomised trial in Quang Ninh province, Vietnam.2018Inngår i: Journal of Epidemiology and Community Health, ISSN 0143-005X, E-ISSN 1470-2738Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Little is know about whether the effects of community engagement interventions for child survival in low-income and middle-income settings are sustained. Seasonal variation and secular trend may blur the data. Neonatal mortality was reduced in a cluster-randomised trial in Vietnam where laywomen facilitated groups composed of local stakeholders employing a problem-solving approach for 3 years. In this analysis, we aim at disentangling the secular trend, the seasonal variation and the effect of the intervention on neonatal mortality during and after the trial.

    METHODS: In Quang Ninh province, 44 communes were allocated to intervention and 46 to control. Births and neonatal deaths were assessed in a baseline survey in 2005, monitored during the trial in 2008-2011 and followed up by a survey in 2014. Time series analyses were performed on monthly neonatal mortality data.

    RESULTS: There were 30 187 live births and 480 neonatal deaths. The intervention reduced the neonatal mortality from 19.1 to 11.6 per 1000 live births. The reduction was sustained 3 years after the trial. The control areas reached a similar level at the time of follow-up. Time series decomposition analysis revealed a downward trend in the intervention areas during the trial that was not found in the control areas. Neonatal mortality peaked in the hot and wet summers.

    CONCLUSIONS: A community engagement intervention resulted in a lower neonatal mortality rate that was sustained but not further reduced after the end of the trial. When decomposing time series of neonatal mortality, a clear downward trend was demonstrated in intervention but not in control areas.

    Safety impacts of implementing median bus lane system in Seoul Metropolitan Area: vehicle-to-vehicle and vehicle-to-pedestrian crashes2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In metropolitan areas, public transportation has been encouraged as a sustainable mode because they can effectively transport many people and have less impact on traffic congestion and environment. In order to increase public transportation ridership, many jurisdictions have attempted to provide improved travel time and reliability of the public transportation system. These efforts include installing transit signal priority, dedicated median/curb bus lanes, bus rapid transit, bus bypass shoulder lanes, et cetera. In Korea, dedicated median bus lanes have been installed and operated since 1996. Currently, approximately 116km of the dedicated median bus lanes on 38 corridors are operational. The implementation of the dedicated median bus lanes in Seoul Metropolitan Area have been successful as they it resulted in the increased travel speed (15 km/h to 19km/h), bus arrival time accuracy (±1 min to 2 min), and daily bus-ridership (from 5.6 million to 5.75 million).

    Although there have been several studies that evaluated the operational effectiveness of the exclusive bus lanes in Seoul, few studies have assessed the safety impacts. This study aims at estimating the impacts of implementing median bus lane system in Seoul Metropolitan Areas for vehicle-to-vehicle and vehicle-to-pedestrian crashes. In order to achieve the objective, a before-and-after study with comparison group method was employed and estimated crash modification factors (CMFs).

    Health-related quality of life determinants among Rwandan women after delivery: does antenatal care utilization matter? A cross-sectional study2018Inngår i: Journal of Health, Population and Nutrition, ISSN 1606-0997, E-ISSN 2072-1315, Vol. 37, artikkel-id 12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Despite the widespread use of antenatal care (ANC), its effectiveness in low-resource settings remains unclear. In this study, self-reported health-related quality of life (HRQoL) was used as an alternative to other maternal health measures previously used to measure the effectiveness of antenatal care. The main objective of this study was to determine whether adequate antenatal care utilization is positively associated with women's HRQoL. Furthermore, the associations between the HRQoL during the first year (113 months) after delivery and socio-economic and demographic factors were explored in Rwanda.

    Methods: In 2014, we performed a cross-sectional population-based survey involving 922 women who gave birth 1-13 months prior to the data collection. The study population was randomly selected from two provinces in Rwanda, and a structured questionnaire was used. HRQoL was measured using the EQ-5D-3L and a visual analogue scale (VAS). The average HRQoL scores were computed by demographic and socio-economic characteristics. The effect of adequate antenatal care utilization on HRQoL was tested by performing two multivariable linear regression models with the EQ-5D and EQ-VAS scores as the outcomes and ANC utilization and socio-economic and demographic variables as the predictors.

    Results: Adequate ANC utilization affected women's HRQoL when the outcome was measured using the EQ-VAS. Social support and living in a wealthy household were associated with a better HRQoL using both the EQ-VAS and EQ-5D. Cohabitating, and single/unmarried women exhibited significantly lower HRQoL scores than did married women in the EQ-VAS model, and women living in urban areas exhibited lower HRQoL scores than women living in rural areas in the ED-5D model. The effect of education on HRQoL was statistically significant using the EQ-VAS but was inconsistent across the educational categories. The women's age and the age of their last child were not associated with their HRQoL.

    Conclusions: ANC attendance of at least four visits should be further promoted and used in low-income settings. Strategies to improve families' socio-economic conditions and promote social networks among women, particularly women at the reproductive age, are needed.

    Tailoring visualization applications for tasks and users2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Exponential increases in available computational resources over the recent decades have fueled an information explosion in almost every scientific field. This has led to a societal change shifting from an information-poor research environment to an over-abundance of information. As many of these cases involve too much information to directly comprehend, visualization proves to be an effective tool to gain insight into these large datasets. While visualization has been used since the beginning of mankind, its importance is only increasing as the exponential information growth widens the difference between the amount of gathered data and the relatively constant human ability to ingest information. Visualization, as a methodology and tool of transforming complex data into an intuitive visual representation can leverage the combined computational resources and the human cognitive capabilities in order to mitigate this growing discrepancy.

    A large portion of visualization research is, directly or indirectly, targets users in an application domain, such as medicine, biology, physics, or others. Applied research is aimed at the creation of visualization applications or systems that solve a specific problem within the domain. Combining prior research and applying it to a concrete problem enables the possibility to compare and determine the usability and usefulness of existing visualization techniques. These applications can only be effective when the domain experts are closely involved in the design process, leading to an iterative workflow that informs its form and function. These visualization solutions can be separated into three categories: Exploration, in which users perform an initial study of data, Analysis, in which an established technique is repeatedly applied to a large number of datasets, and Communication in which findings are published to a wider public audience.

    This thesis presents five examples of application development in finite element modeling, medicine, urban search & rescue, and astronomy and astrophysics. For the finite element modeling, an exploration tool for simulations of stress tensors in a human heart uses a compression method to achieve interactive frame rates. In the medical domain, an analysis system aimed at guiding surgeons during Deep Brain Stimulation interventions fuses multiple modalities in order to improve their outcome. A second analysis application is targeted at the Urban Search & Rescue community supporting the extraction of injured victims and enabling a more sophisticated decision making strategy. For the astronomical domain, first, an exploration application enables the analysis of time-varying volumetric plasma simulations to improving these simulations and thus better predict space weather. A final system focusses on combining all three categories into a single application that enables the same tools to be used for Exploration, Analysis, and Communication, thus requiring the handling of large coordinate systems, and high-fidelity rendering of planetary surfaces and spacecraft operations.

    Asymptomatic Prenatal Zika Virus Infection and Congenital Zika Syndrome2018Inngår i: Open Forum Infectious Diseases, ISSN 2328-8957, Vol. 5, nr 4Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To investigate to what extent asymptomatic vs symptomatic prenatal Zika virus infections contribute to birth defects, we identified 3 prospective and 8 retrospective studies. The ratio varied greatly in the retrospective studies, most likely due to recruitment and recall bias. The prospective studies revealed a ratio of 1: 1 for asymptomatic vs symptomatic maternal Zika infections resulting in adverse fetal outcomes.

    Radical Right, Identity, and Retaliation2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Economic Distress and Support for Far-right Parties – Evidence from Sweden. This paper studies the effects of economic distress on support for far-right parties. Using Swedish election data, I show that layoff notifications among low-skilled native-born workers account for 31 percent of the increased vote share for the Swedish far-right party the Sweden Democrats. The effect of layoff notifications on support for the Sweden Democrats is larger in areas with a high share of low-skilled immigrants, and in areas with a low share of high-skilled immigrants. These findings are in line with theories suggesting that voters attribute their impaired economic status to immigration, due to labor market concerns. Furthermore, I find no effects on voting for other anti-EU and anti-globalization parties, challenging the notion that economic distress increases anti-globalization sentiment. Using detailed survey data, I present suggestive evidence of how increased salience of political issues related to immigration channels unemployment risk into support for far-right parties.

    The Origins of Common Identity: Division, Homogenization Policies and Identity Formation in Alsace-Lorraine. We exploit the quasi-exogenous division of the French regions Alsace and Lorraine after the Franco-Prussian War in 1870 due to disagreements in the German leadership to provide evidence of group identity formation within historically homogeneous regions. People in the treated area, which was exposed to repressive homogenization policies aimed to suppress group identity, express a stronger regional identity and support more regional autonomy today. Using a regression discontinuity design at the municipal level, we find that support for two crucial referenda, which would have increased regional autonomy, subscription rates to regional newspapers, and regionalist party votes are significantly higher in the treated area. The results are robust across different specifications and bandwidths, and not driven by language differences, large agglomerations or distance to foreign countries. The differences in regional identity are strongest for the first two age cohorts after World War II and become weaker for later generations.

    Gender Differences in Revenge and Strategic play: A Natural Experiment. This paper provides new evidence of gender differences in retaliatory behavior. Using game show data from a natural setting where stakes are high, we ask whether men are more likely to retaliate following an attack and whether the gender of the target matters for this decision. The behavior studied in this paper is the decision of whom to send the question to in a quiz show setting. We observe a 23 percent gender gap in the propensity to retaliate: women are less likely to seek revenge. The gender of the target matters for women but not for men, with women being more likely to retaliate against men than women. In addition, we show that retaliation is a successful way to avert future attacks in the short term. This is especially true for women, yet we find that women seek less revenge than men.

    Multiphysics Characterization of SiC Power Modules2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis proposes several novel silicon carbide power module design concepts. The goal has been to address the problems with the present designs. The electrical, thermal, and thermomechanical performances of the demonstrators have been evaluated along with presentations of methodologies of experimental and numerical characterizations.

    Compact high-temperature power modules with adequate cooling systems are attractive to automotive applications. Therefore, a novel thermal design of a double-sided liquid/air cooled silicon carbide power module (1200 V, 200 A) has been proposed. The concept integrates a dc-link capacitor, a gate driver board, and finned cooling channels. The cooling concept has been evaluated for three application scenarios based on a validated computational fluid dynamics model. Moreover, a simulation methodology has been developed to quantify the effect of different materials and thicknesses of the cold plates on the temperature of the silicon carbide power dies.

    For medium- and high-power applications, contemporary research concludes that the reliability of the existing packaging technology needs to be improved. Therefore, this work proposes a novel press-pack silicon carbide power module concept. The concept enables bondless package and allows for an order of magnitude higher clamping force on the heatsinks than what can be applied on the dies. First, experimental and numerical methodologies for thermomechanical performance characterization of a press-pack structure have been investigated. By using digital image correlation technique, the deformation of each stacked material layer has been obtained. The developed experiment has led to an analytical estimation of friction coefficients on the contact interfaces. The co-influence of the design parameters on the thermomechanical performance of the press-pack structure has been analyzed through a parametric study based on a finite element model. Second, the novel double press-pack silicon carbide power module concept has been evaluated in a demonstrator in terms of parasitic inductance, thermal resistance, and thermomechanical stress.

    Furthermore, many of the power module designs only stay at the stage of proof-of-concept due to the cost of retooling of the manufacturing facility. Embedded power modules which employ advanced printed circuit board processing and die embedding technologies, enable a solution with possibility of low cost and mass production. Therefore, a novel design concept of a three-phase embedded power module (1200 V, 20 A) has been proposed. Simulation-driven design development has been implemented and lead to a fabricated demonstrator. The electromagnetic, thermal, and thermomechanical performances of the concept have been evaluated by simulations and compared to a commercially available power module.

    Of Pipes and Bends2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This work is concerned with the transition to turbulence of the flow in bent pipes, but it also includes an analysis of large-scale turbulent structures and their use for flow control.

    The flow in a toroidal pipe is selected as it represents the common asymptotic limit between spatially developing and helical pipes. The study starts with a characterisation of the laminar flow as a function of curvature and the Reynolds number Re, since the so-called Dean number is found to be of little use except for infinitesimally low curvatures. It is found that the flow is modally unstable and undergoes a Hopf bifurcation for any curvature greater than zero. The bifurcation is studied in detail, and an effort to connect this modal instability with the linearly stable straight pipe is also presented.

    This flow is not only modally unstable, but undergoes subcritical transition at low curvatures. This scenario is found to bear similarities to straight pipes, but also fundamental differences such as weaker turbulent structures and the apparent absence of puff splitting. Toroidal pipe flow is peculiar, in that it is one of the few fluid flows presenting both sub- and supercritical transition to turbulence; the critical point where the two scenarios meet is therefore of utmost interest. It is found that a bifurcation cascade and featureless turbulence actually coexist for a range of curvature and Re, and the attractors of the respective structures have a small but finite basin of attraction.

    In 90◦ bent pipes at higher Re large-scale flow structures cause an oscilla- tory motion known as swirl-switching. Three-dimensional proper orthogonal decomposition is used to determine the cause of this phenomenon: a wave-like structure which is generated in the bent section, and is possibly a remnant of a low-Re instability.

    The final part of the thesis has a different objective: to reduce the turbulent frictional drag on the walls of a channel by employing a control strategy independent of Re-dependent turbulent scales, initially proposed by Schoppa & Hussain [Phys. Fluids 10:1049–1051 (1998)]. Results show that the original method only gives rise to transient drag reduction while a revised version is capable of sustained drag reduction of up to 18%. However, the effectiveness of this control decreases rapidly as the Reynolds number is increased, and the only possibility for high-Re applications is to use impractically small actuators.

    Optical properties of GaN and InGaN studied by time- and spatially-resolved spectroscopy2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The past decade has seen rapid expansion in the use of group III-nitride based devices. White InGaN LEDs are substituting incandescent light bulbs, space satellite industry adopting ion-radiation-resistant GaN transistors, and AlGaN deep UV LEDs are increasingly being used for water disinfection and air purification. Despite this success, performance and efficiency of many devices is still far from optimal with many fundamental material properties still disputed and technological issues not solved. For example, the energy difference between the lowest conduction band valleys in the case of GaN is still being debated, and an efficient white light source of monolithic three-color LED has still not been achieved, due to the poor quantum efficiency of green-emitting quantum wells.

    In view of these material challenges, this thesis was dedicated to studies of GaN, InGaN and their quantum wells with the help of time- and spatially- resolved spectroscopy and numerical modeling. This work provides new insights on both the fundamental and the growth-induced properties. Specifically, the energy difference between the lowest conduction band valleys in GaN, a key parameter for electronic devices, has been experimentally evaluated. In addition, electron scattering rates and satellite valley’s effective mass have been estimated by modeling pump-probe transients with rate equations. A study on Fe doped GaN has revealed that, depending on the device operation rate, different Fe+3 states should be considered when modelling GaN:Fe-based optoelectronic devices. Moreover, electron and hole capture coefficients and their temperature dependence have been determined. It has also been demonstrated that the random alloy model could only be used to describe emission and absorption linewidths in the InGaN alloy for a very low-In-content samples. Indium incorporation into the alloy has been found to be affected by the geometry of monolayer step edges that are formed during growth. Time-resolved scanning near-field photoluminescence spectroscopy studies on non-polar and semi-polar InGaN/GaN quantum wells have demonstrated that the common assumption of a spatially uniform radiative recombination rate is not always correct. Finally, it has been found that for a moderate to high-In-content QW the photoluminescence linewidth is defined primarily by variations of alloy composition and not well width fluctuations.

    Science and Culture in the Kerguelen Islands: a relational approach to the spatial formation of a subantarctic archipelago2018Inngår i: Island Studies Journal, ISSN 1715-2593, E-ISSN 1715-2593Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Kerguelen Islands are devoid of a permanent population, but are nonetheless interlinked to past and current human activities that have shaped their subantarctic landscape. In the past decades, the archipelago has become a French outpost for scientific research where scientists, support staff, research assistants, and travelers assemble during temporary missions. In this article, I present the spatial formation of islands as relational in order to explore how the material and the cultural converge to make the Kerguelen Islands a place of both mundane practice and global interconnection. These spatialities intertwine the features of the landscape with pre-departure preparations, animal encounters, scientific rigour, daily routines, and past human activities. I advance these narratives by analyzing 18 blogs of French sojourners who have spent extensive time on the Kerguelen Islands. I ultimately give islands without a permanent population a character unlike that of isolation and contemplation as is usually attributed to cold-water islands of the (sub) polar seas.

    Measurements of hard X-ray polarization from the Crab and Cygnus X-12018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Polarimetry provides insights into the emission mechanisms of astrophysical sources by elucidating their magnetic field and geometry. Hard X-rays are produced in \mbox{regions} with strong magnetic fields or strong gravitational effects, which makes them a probe of extreme environments. This thesis describes the design, \mbox{calibration} and data analysis from the balloon-borne hard X-ray polarimeters the PoGOLite Pathfinder and its upgrade PoGO+. These instruments have measured the polari-zation from the Crab nebula and pulsar, and of the black hole binary Cygnus X-1.

    Paper I explores to what extent the statistical uncertainties on the polarization parameters are non-Gaussian when the number of photons is low, as tends to be the case for balloon-borne instruments.With this in mind, a Bayesian method is used for data analysis in the subsequent papers. Paper II describes the measurement of the polarization of the Crab system in the 20-120 keV energy range conducted by the PoGOLite Pathfinder. Although the result is modest in its statistical significance it paves the way for the design of the upgraded instrument PoGO+.

    The PoGO+ mission was conceived to remedy the shortcomings of the PoGOLite Pathfinder design and observation strategy, as well as the pre-flight calibration, which the focus of Paper III. Significant improvements are made to the detector response model, optimization of data acquisition thresholds, online veto system and to the general calibration procedure. When combined with interspersed target and background measurements, systematic uncertainties are significantly smaller for PoGO+ than for the PoGOLite Pathfinder.

    The main scientific results are presented in Papers IV and V for the Crab (20-160 keV) and Cygnus X-1 (20-180 keV), respectively. For the Crab, PoGO+ does not support a rapid increase in the polarization fraction claimed previously. Additionally, the hard X-ray emission must be produced close to the pulsar and possibly in the fine structures of the nebula. This is in agreement with X-ray images from other instruments. For Cygnus X-1, the polarization measurements constrain the geometry by rejecting the model where the hard X-rays are produced in a compact corona close to the black hole and support the extended corona model.

    The thesis demonstrates how balloon-borne instruments can be improved over the course of several campaigns and can contribute to the testing of detector design, development of analysis methods and provide new scientific results for bright X-ray sources.

    National environmental evaluation systems: guiding towards sustainability?2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background: Dealing with environmental threats is one of the largest, if not the largest, challenge contemporary societies face. One way to better deal with this challenge would be to produce knowledge that can be used to improve environmental work and environmental policy and thus ultimately contribute to sustainable development. National environmental evaluations, which this thesis explores, could potentially fill this function because they are supposed to generate applicable and useful knowledge for improving environmental policy and practice for a sustainable transition. However, what different environmental actors view as useful knowledge varies, and needs to be empirically investigated. Against this background, the aim of this thesis is to investigate whether, and how, national environmental evaluation systems contribute to key actors’ environmental work and sustainable development. The thesis explores two national environmental evaluation systems in Sweden.

    Method: A mixed methods approach is applied that combines three methods. Firstly, a narrative synthesis is developed and applied to compile a list of sustainable development effects from national environmental evaluations. Secondly, a critical program theory is used to investigate the evaluation system’s underlying logic and to assess the likelihood of it achieving its intended effects. Thirdly, a directed content analysis is used to explore the usability and use of environmental evaluations and evaluation systems. The methods are applied to various documents, interviews with key actors, and observations at two environmental seminars.

    Results: The results show that, to contribute to sustainable development in the context of evaluation systems and network governance, environmental evaluations need to be of sufficient quality and meet different stakeholders’ knowledge needs. However, only some evaluations meet this demand. The main value of national environmental evaluations and evaluation systems is that they reinforce the national objectives, provide a recurrent report on achievement of objectives, and push actors to take responsibility to improve their environmental work.

    ORCHIDEE-SOM: Modeling soil organic carbon (SOC) and dissolved organic carbon (DOC) dynamics along vertical soil profiles in Europe2018Inngår i: Geoscientific Model Development, ISSN 1991-959X, E-ISSN 1991-9603, Vol. 11, nr 3, s. 937-957Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Current Land Surface Models (LSMs) typically represent soils in a very simplistic way, assuming soil organic carbon (SOC) as a bulk, thus impeding a correct representation of deep soil carbon dynamics. Moreover, LSMs generally neglect the production and export of dissolved organic carbon (DOC) from soils to rivers, leading to overestimations of the potential carbon sequestration on land. These common oversimplified processing of SOC in LSMs is partly responsible for the large uncertainty in the predictions of the soil carbon response to climate change. In this study, we present a new soil carbon module called ORCHIDEE-SOM, embedded within the land surface model ORCHIDEE, which is able to reproduce the DOC and SOC dynamics in a vertically discretized soil to two meters. The model includes processes of biological production and consumption of SOC and DOC, DOC adsorption on- and desorption from soil minerals, diffusion of SOC and DOC and DOC transport with water through and out of the soils to rivers. We evaluated ORCHIDEE-SOM against observations of DOC concentrations and SOC stocks from four European sites with different vegetation covers: a coniferous forest, a deciduous forest, a grassland and a cropland. The model was able to reproduce the SOC stocks along their vertical profiles at the four sites and the DOC concentrations within the range of measurements, with the exception of the DOC concentrations in the upper soil horizon at the coniferous forest. However, the model was not able to fully capture the temporal dynamics of DOC concentrations. Further model improvements should focus on a plant- and depth- dependent parameterization of the new input model parameters, such as the decomposition times of DOC and the microbial carbon use efficiency. We suggest that this new soil module, when parameterized for global simulations, will improve the representation of the global carbon cycle in LSMs, thus helping to constrain the predictions of the future SOC response to global warming.\textless/p\textgreater

    An in vitro evaluation of browser and grazer fermentation efficiency and microbiota using European moose spring and summer foods2018Inngår i: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 8, s. 4183-4196Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Evolutionary morphological and physiological differences between browsers and grazers contribute to species- specific digestion efficiency of food resources. Rumen microbial community structure of browsers is supposedly adapted to characteristic nutrient composition of the diet source. If this assumption is correct, domesticated ruminants, or grazers, are poor model animals for assessing the nutritional value of food consumed by browsing game species. In this study, typical spring and summer foods of the European moose (Alces alces) were combined with rumen fluid collected from both dairy cows (Bos taurus) and from moose, with the aim of comparing fer- mentation efficiency and microbial community composition. The nutritional value of the food resources was characterized by chemical analysis and advanced in vitro measurements. The study also addressed whether or not feed evaluation based on in vitro techniques with cattle rumen fluid as inoculum could be a practical alternative when evaluating the nutritional value of plants consumed by wild browsers. Our re- sults suggest that the fermentation characteristics of moose spring and summer food are partly host- specific and related to the contribution of the bacterial phyla Firmicutes and Bacteriodetes to the rumen microbial community. Host- specific adaptations of the ruminal microbial community structure could be explained from the evolutionary adaptations related to feeding habitats and morphophysiological differences be- tween browsers and grazers. However, the observed overall differences in microbial community structure could not be related to ruminal digestion parameters measured in vitro. The in vitro evaluation of digestion efficiency reveals that equal amounts of methane were produced across all feed samples regardless of whether the ruminal fluid was from moose or dairy cow. The results of this study suggested that the nutri- tional value of browsers’ spring and summer food can be predicted using rumen fluid from domesticated grazers as inoculum in in vitro assessments of extent of digestion when excluding samples of the white water lily root, but not of fermentation characteristics as indicated by the proportions of individual fermentation fatty acids to the total of volatile fatty acids.

    Inter-laboratory testing of the effect of DNA blocking reagent G2 on DNA extraction from low-biomass clay samples2018Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 8, artikkel-id 5711Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Here we show that a commercial blocking reagent (G2) based on modified eukaryotic DNA significantly improved DNA extraction efficiency. We subjected G2 to an inter-laboratory testing, where DNA was extracted from the same clay subsoil using the same batch of kits. The inter-laboratory extraction campaign revealed large variation among the participating laboratories, but the reagent increased the number of PCR-amplified16S rRNA genes recovered from biomass naturally present in the soils by one log unit. An extensive sequencing approach demonstrated that the blocking reagent was free of contaminating DNA, and may therefore also be used in metagenomics studies that require direct sequencing.

    The challenge of monitoring glaciers with extreme altitudinal range: mass-balance reconstruction for Kahiltna Glacier, Alaska2018Inngår i: Journal of Glaciology, ISSN 0022-1430, E-ISSN 1727-5652, Vol. 64, nr 243, s. 75-88Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Glaciers spanning large altitudinal ranges often experience different climatic regimes with elevation, creating challenges in acquiring mass-balance and climate observations that represent the entire glacier. We use mixed methods to reconstruct the 1991-2014 mass balance of the Kahiltna Glacier in Alaska, a large (503 km(2)) glacier with one of the greatest elevation ranges globally (264-6108m a. s.l.). We calibrate an enhanced temperature index model to glacier-wide mass balances from repeat laser altimetry and point observations, finding a mean net mass-balance rate of -0.74 mw.e. a(-1)(+/-sigma = 0.04, std dev. of the best-performing model simulations). Results are validated against mass changes from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites, a novel approach at the individual glacier scale. Correlation is strong between the detrended model-and GRACE-derived mass change time series (R-2 = 0.58 and p << 0.001), and between summer (R-2 = 0.69 and p = 0.003) and annual (R-2 = 0.63 and p = 0.006) balances, lending greater confidence to our modeling results. We find poor correlation, however, between modeled glacier-wide balances and recent single-stake monitoring. Finally, we make recommendations for monitoring glaciers with extreme altitudinal ranges, including characterizing precipitation via snow radar profiling.

    Engineered cyanobacteria with enhanced growth show increased ethanol production and higher biofuel to biomass ratio2018Inngår i: Metabolic engineering, ISSN 1096-7176, E-ISSN 1096-7184, Vol. 46, s. 51-59Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Calvin-Benson-Bassham (CBB) cycle is the main pathway to fix atmospheric CO2 and store energy in carbon bonds, forming the precursors of most primary and secondary metabolites necessary for life. Speeding up the CBB cycle theoretically has positive effects on the subsequent growth and/or the end metabolite(s) production. Four CBB cycle enzymes, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), fructose-1,6/sedoheptulose-1,7-bisphosphatase (FBP/SBPase), transketolase (TK) and aldolase (FBA) were selected to be co-overexpressed with the ethanol synthesis enzymes pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH) in the cyanobacterium Synechocystis PCC 6803. An inducible promoter, PnrsB, was used to drive PDC and ADH expression. When PnrsB was induced and cells were cultivated at 65 µmol photons m−2 s−1, the RuBisCO-, FBP/SBPase-, TK-, and FBA-expressing strains produced 55%, 67%, 37% and 69% more ethanol and 7.7%, 15.1%, 8.8% and 10.1% more total biomass (the sum of dry cell weight and ethanol), respectively, compared to the strain only expressing the ethanol biosynthesis pathway. The ethanol to total biomass ratio was also increased in CBB cycle enzymes overexpressing strains. This study experimentally demonstrates that using the cells with enhanced carbon fixation, when the product synthesis pathway is not the main bottleneck, can significantly increase the generation of a product (exemplified with ethanol), which acts as a carbon sink.

    The greedy walk on an inhomogeneous Poisson process2018Inngår i: Electronic Communications in Probability, ISSN 1083-589X, E-ISSN 1083-589X, Vol. 23, artikkel-id 14Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The greedy walk is a deterministic walk that always moves from its current position to the nearest not yet visited point. In this paper we consider the greedy walk on an inhomogeneous Poisson point process on the real line. We prove that the property of visiting all points of the point process satisfies a 0-1 law and determine explicit sufficient and necessary conditions on the mean measure of the point process for this to happen. Moreover, we provide precise results on threshold functions for the property of visiting all points.

    Sequential testing of a Wiener process with costly observations2018Inngår i: Sequential Analysis, ISSN 0747-4946, E-ISSN 1532-4176, Vol. 37, nr 1, s. 47-58Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We consider the sequential testing of two simple hypotheses for the drift of a Brownian motion when each observation of the underlying process is associated with a positive cost. In this setting where continuous monitoring of the underlying process is not feasible, the question is not only whether to stop or to continue at a given observation time but also, if continuing, how to distribute the next observation time. Adopting a Bayesian methodology, we show that the value function can be characterized as the unique fixed point of an associated operator and that it can be constructed using an iterative scheme. Moreover, the optimal sequential distribution of observation times can be described in terms of the fixed point.

    An eHealth program versus a standard care supervised health program and associated health outcomes in individuals with mobility disability: study protocol for a randomized controlled trial2018Inngår i: Trials, ISSN 1745-6215, E-ISSN 1745-6215, Vol. 19, artikkel-id 258Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Young adults with mobility disability (MD) are less likely to engage in regular physical activity (PA) compared with their able-bodied peers and inactive adults with a MD are more likely to report one or more chronic diseases compared to those who are physically active. Despite the vast amount of research published in the field of PA interventions over the past decades, little attention has been focused on interventions aiming to increase PA among individuals with MD. Thus, we propose to compare the effects of an eHealth program compared to a usual care supervised health program on levels of PA and other health behaviors. 

    Methods: The current intervention will use a randomized controlled trial (RCT) design with two treatment groups (an eHealth program and a usual care supervised health program) in young adults with newly acquired MD. In total, 110 young adults (aged 18-40 years) with a MD, acquired within the past 3 years, will be recruited to participate in a 12-week intervention. The primary study outcome is accelerometer-measured time spent in moderate to vigorous PA. Secondary outcomes includes health-related quality of life, depression, stress, fitness, body composition, diet, musculoskeletal pain, motivation to exercise and work ability.

    Discussion: There is a lack of RCTs investigating effective ways to increase levels of PA in young adults with MD. Increased levels of PA among this physically inactive population have the potential to substantially improve health-related outcomes, possibly more so than in the general population. The trial will put strong emphasis on optimizing exercise adherence and investigating feasibility in the two treatment programs. The Ethical Review Board (EPN) at Karolinska Institutet has approved the study (2017/1206-31/1).

    Building Effective Transnational Partnerships: The Case of Smart Lighting2018Annet (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    This policy brief examines the requirements for building effective transnational partnerships in different policy fields, based on the lessons learned from the recent Lighting Metropolis project – a cross-border innovation venture between Denmark and Sweden that sought to develop smart lighting solutions in urban environments. The brief begins with an overview of this new technology area, before outlining the main opportunities and challenges in the implementation of smart lighting throughout Europe. This is followed by a review of the key findings from Lighting Metropolis, with a focus on assessing the experiences of transnational co-operation identified during the project. Finally, the concluding section outlines a number of recommendations for enhancing transnational collaboration. The policy brief has been prepared by Nordregio as part of the BSR Stars S3 project. It is based on a literature review and interviews conducted with partners involved in Lighting Metropolis.

    Antibiotic resistance ABCF proteins reset the peptidyl transferase centre of the ribosome to counter translational arrest2018Inngår i: Nucleic Acids Research, ISSN 0305-1048, E-ISSN 1362-4962, Vol. 46, nr 7, s. 3753-3763Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Several ATPases in the ATP-binding cassette F (ABCF) family confer resistance to macrolides, lincosamides and streptogramins (MLS) antibiotics. MLS are structurally distinct classes, but inhibit a common target: the peptidyl transferase (PTC) active site of the ribosome. Antibiotic resistance (ARE) ABCFs have recently been shown to operate through direct ribosomal protection, but the mechanistic details of this resistance mechanism are lacking. Using a reconstituted translational system, we dissect the molecular mechanism of Staphylococcus haemolyticus VgaA(LC) and Enterococcus faecalis LsaA on the ribosome. We demonstrate that VgaA(LC) is an NTPase that operates as a molecular machine strictly requiring NTP hydrolysis (not just NTP binding) for antibiotic protection. Moreover, when bound to the ribosome in the NTP-bound form, hydrolytically inactive EQ(2) ABCF ARE mutants inhibit peptidyl transferase activity, suggesting a direct interaction between the ABCF ARE and the PTC. The likely structural candidate responsible for antibiotic displacement by wild type ABCF AREs, and PTC inhibition by the EQ(2) mutant, is the extended inter-ABC domain linker region. Deletion of the linker region renders wild type VgaA(LC) inactive in antibiotic protection and the EQ(2) mutant inactive in PTC inhibition.

    Improving Underwater Accuracy by Empirical Weighting of Image Observations2018Inngår i: ISPRS Technical Commission II Symposium 2018, ISPRS , 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    An underwater imaging system with camera and lens behind a flat portdoes not behave as a standard pinhole camera with additionalparameters. Indeed, whenever the entrance pupil of the lens is not incontact with the flat port, the standard photogrammetric model is notsuited anymore and an extended mathematical model that considers thedifferent media would be required. Therefore, when dealing with flatports, the use of the classic photogrammetric formulation represents asimplification of the image formation phenomenon, clearly causing adegradation in accuracy. Furthermore, flat ports significantly changethe characteristics of the enclosed imaging device and negativelyaffect the image quality, introducing heavy curvilinear distortionsand optical aberrations. With the aim of mitigating the effect ofsystematic errors introduced by a combination of (i) image qualitydegradation, induced by the flat ports, and (ii) a non-rigorousmodelling of refraction, this paper presents a stochastic model forimage observations that penalises those that are more affected byaberrations and departure from the pinhole model. Experiments werecarried out at sea and in pools showing that the use of the proposedstochastic model is beneficial for the final accuracy withimprovements up to 50%.

    Modular Bundle Adjustment for Photogrammeric Computations2018Inngår i: ISPRS Technical Commission II Symposium 2018, ISPRS , 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we investigate how the residuals in bundle adjustmentcan be split into a composition of simple functions. According to thechain rule, the Jacobian (linearisation) of the residual can be formedas a product of the Jacobians of the individual steps. Whenimplemented, this enables a modularisation of the computation of thebundle adjustment residuals and Jacobians where each component haslimited responsibility. This enables simple replacement of componentsto e.g. implement different projection or rotation models byexchanging a module. The technique has previously been used toimplement bundle adjustment in the open-source package DBAT (Borlinand Grussenmeyer, ¨ 2013) based on the Photogrammetric and ComputerVision interpretations of Brown (1971) lens distortion model. In thispaper, we applied the technique to investigate how affine distortionscan be used to model the projection of a tilt-shift lens. Two extendeddistortion models were implemented to test the hypothesis that theordering of the affine and lens distortion steps can be changed toreduce the size of the residuals of a tilt-shift lens calibration.Results on synthetic data confirm that the ordering of the affine andlens distortion steps matter and is detectable by DBAT. However, whenapplied to a real camera calibration data set of a tilt-shift lens, nodifference between the extended models was seen. This suggests thatthe tested hypothesis is false and that other effects need to bemodelled to better explain the projection. The relatively lowimplementation effort that was needed to generate the models suggestthat the technique can be used to investigate other novel projectionmodels in photogrammetry, including modelling changes in the 3Dgeometry to better understand the tilt-shift lens.
