    Robust algorithm for detecting floodwater in urban areas using synthetic aperture radar images2018Inngår i: Journal of Applied Remote Sensing, ISSN 1931-3195, E-ISSN 1931-3195, Vol. 12, nr 4, artikkel-id 045011Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Flooding is a major hazard in both rural and urban areas worldwide, but it is in urban areas that the impacts are most severe. High-resolution synthetic aperture radar (SAR) sensors are able to detect flood extents in urban areas during both day- and night-time. If obtained in near real time, these flood extents can be used for emergency flood relief management or as observations for assimilation into flood forecasting models. A method for detecting flooding in urban areas using near real-time SAR data is developed and extensively tested under a variety of scenarios involving different flood events and different images. The method uses an SAR simulator in conjunction with LiDAR data of the urban area to predict areas of radar shadow and layover in the image caused by buildings and taller vegetation. Of the urban water pixels visible to the SAR, the flood detection accuracy averaged over the test examples is 83%, with a false alarm rate of 9%. The results indicate that flooding can be detected in the urban area to reasonable accuracy but that this accuracy is limited partly by the SAR's poor visibility of the urban ground surface due to shadow and layover.

    The acceleration of the Moon and the Universe - the Mass of the Graviton2017Inngår i: Advances in Astrophysics, ISSN 2415-6450, Vol. 2, nr 3, s. 184-196Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To get accurate knowledge about the longitudinal motion of the Moon we must use the oldest preserved interpretable depictions and texts from the ancient cultures. Well documented total solar eclipses from Sumerian cylinder seals, Sumerian, Babylonian, Assyrian, Chinese, Hittite and Greek texts, and depictions on the Swedish rock-carvings from the Bronze Age, have been used in an analysis, performed by the author in 2011, to determine the lunar sidereal secular acceleration. It was based on 33 ancient total or almost total solar eclipses back to 3653 BC. In 2014 and 2016 the margins of error was determined. The new value for the lunar sidereal secular acceleration in longitude = -30.128±0.0035 arcseconds/(century)2 ("/cy2). The lunar secular acceleration, from the Lunar Laser Range (LLR) measurements, -25.856 ±0.003"/cy2, must be corrected for the relativistic effect, -3.604"/cy2, in the Earth-Moon inertial system, to get the lunar sidereal secular acceleration, –29.460 "/cy2, corrected for General Relativity. The difference between this value and the new calibration, -0.668±0.0046"/cy2, corresponds to the cosmological acceleration predicted by Dvali et al. in a Modified Theory of gravity. This value corresponds to a mass of the graviton = 1.306 ±0.009 x 10-56 grams.   If this theory is correct, there is no need for the enigmatic Dark Energy.

    Tracingsilicate weathering processes in the permafrost-dominated Lena River watershedusing lithium isotopes2019Inngår i: Geochimica et Cosmochimica Acta, ISSN 0016-7037, E-ISSN 1872-9533, Vol. 245, s. 154-171Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Increasing global temperatures are causing widespread changes in the Arctic, including permafrost thawing and altered freshwater inputs and trace metal and carbon fluxes into the ocean and atmosphere. Changes in the permafrost active layer thickness can affect subsurface water flow paths and water-rock interaction times, and hence weathering processes. Riverine lithium isotope ratios (reported as δ7Li) are tracers of silicate weathering that are unaffected by biological uptake, redox, carbonate weathering and primary lithology. Here we use Li isotopes to examine silicate weathering processes in one of the largest Russian Arctic rivers: the Lena River in eastern Siberia. The Lena River watershed is a large multi-lithological catchment, underlain by continuous permafrost. An extensive dataset of dissolved Li isotopic compositions of waters from the Lena River main channel, two main tributaries (the Aldan and Viliui Rivers) and a range of smaller sub tributaries are presented from the post-spring flood/early-summer period at the onset of active layer development and enhanced water-rock interactions. The Lena River main channel (average δ7Lidiss ~19‰) has a slightly lower isotopic composition than the mean global average of 23‰ (Huh

    et al., 1998a). The greatest range of [Li] and δ7Lidiss are observed in catchments draining the south facing slopes of the Verkhoyansk Mountain Range. South-facing slopes in high-latitude, permafrost dominated regions are typically characterised by increased summer insolation and higher daytime temperatures relative to other slope aspects. The increased solar radiation on south-facing catchments promotes repeated freeze-thaw cycles, and contributes to more rapid melting of snow cover, warmer soils, and increased active layer thaw depths. The greater variability in δ7Li and [Li] in the south-facing rivers likely reflect the greater infiltration of melt water and enhanced water rock interactions within the active layer. A similar magnitude of isotopic fractionation is observed between the low-lying regions of the Central Siberian Plateau (and catchments draining into the Viliui River), and catchments draining the Verkhoyansk Mountain Range into the Aldan River. This is in contrast to global rivers in non permafrost terrains that drain high elevations or areas of rapid uplift, where high degrees of physical erosion promote dissolution of freshly exposed primary rock typically yielding low δ7Lidiss, and low lying regions exhibit high riverine δ7Li values resulting from greater water-rock interaction and formation of secondary mineral that fractionates Li isotopes. Overall, the range of Li concentrations and δ7Lidiss observed within the Lena River catchment are comparable to global rivers located in temperate and tropical regions. This suggests that cryogenic weathering features specific to permafrost regions (such as the continual exposure of fresh primary minerals due to seasonal freeze-thaw cycles, frost shattering and salt weathering), and climate (temperature and runoff), are not a dominant control on δ7Li variations. Despite vastly different climatic and weathering regimes, the same range of riverine δ7Li values globally suggests that the same processes govern Li geochemistry – that is, the balance between primary silicate mineral dissolution and the formation (or exchange with) secondary minerals. This has implications for the use of δ7Li as a palaeo weathering tracer for interpreting changes in past weathering regimes.

    Isotopic resonance at 370 ppm deuterium negatively affects kinetics of luciferin oxidation by luciferase2018Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 8, artikkel-id 16249Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Since 1930s, it has been known that some biochemical and biological processes exhibit abnormal kinetics at a deuterium concentration in the local environment of 250-600 ppm, which is 2-4 times higher that the normal concentration of 150 ppm D. We sought to test if the kinetics of firefly luciferase oxidizing luciferin, the reaction widely used as a read-out in various biochemical assays, is also affected by an elevated deuterium content. To this end, both luciferase and luciferin substrate solutions were prepared based on water with extra deuterium added to a concentration ranging from 150 ppm and up to 10,000 ppm (1%). Upon mixing the solutions, the luminescence intensity at different times was compared with that of the corresponding control solutions with 150 ppm D. A broad negative resonance was detected (p < 10(-6)), with a approximate to 20% drop in luminescence at 370 ppm D. Given that, on average, about half of hydrogen atoms in proteins are not exchangeable in solution, this value corresponds to approximate to 260 ppm of deuterium in all enzyme's hydrogens, in a very good agreement with the prediction of the Isotopic resonance hypothesis.

    Skrivande på gymnasiet: Perspektiv på skrivutveckling och textkompetens2018Annet (Annet vitenskapelig)
    Abstract [sv]

    Elevernas skrivutveckling når aldrig ett slutmål – nya genrer och nytt innehåll innebär nya utmaningar och fler steg i utvecklingen mot en avancerad skriftspråkskompetens. En utvecklande skrivundervisning behöver göra eleverna förberedda att möta dessa utmaningar, både under gymnasietiden och i kommande studier och yrkesliv.

    Artikeln föreskriver inte en specifik teoribildning eller en utvald skrivpedagogisk inriktning som svar på hur undervisningen kan möta elevernas behov. Den betonar istället att lärare behöver många redskap och göra medvetna val bland dessa i planeringen av en skrivundervisning som ser till alla delar i den skriftspråkliga kompetensen.

    Artikeln resonerar kring de tendenser som genom åren har präglat skrivundervisningen. Hur ska dagens lärare förhålla sig till olika synsätt och inriktningar? En breddad skrivundervisning förespråkas som på olika sätt främjar utvecklingen av elevernas skriftspråkliga kompetens.

    Data and Visual Analytics for Cyber-physical Systems: Current Situation and Strategies for Action2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Today, cyber-physical systems (CPS) exist everywhere in different sizes, with different functionalities and capabilities. CPS often support critical missions that have significant economic and societal importance. They require software systems, communications technologies, sensors/actuators, embedded technologies, and physical systems to work together seamlessly, and they are seen as a driving force behind digital transformation. This dissertation describes the research work carried out to investigate applicability of data and visual analytics for CPS to overcome three main challenges: interoperability, complexity, and sustainability.

    To this end, several case studies are used to effectively implement and test different data and visual analytics solutions to aid stakeholders when they make decisions on interoperability, complexity, and sustainability for CPS. These studies raised questions about issues found to be of importance for the success of data and visual analytics approaches, including accessibility, availability, quality, volume, and variety of data—issues. Moreover, additional studies are used to show the benefits of blending different approaches, such as systems thinking and design thinking, and the current data analytics readiness of the Swedish industry is assessed through a questionnaire completed by more than a hundred respondents. 

    The data and visual analytics are positioned between digitalization and machine intelligence as a research focus. Data and visual analytics is the next step after digitalizing the information by adding analytical capabilities to the data. It is also an important phase before developing machine intelligence applications. Earlier studies clearly show that only a fraction of companies have machine intelligence applications across the enterprise. One important reason behind this is the lack of strong digital capabilities that big data and advanced data analytics technologies could bring. The findings of the work carried out as part of this thesis show the importance of this middle phase—data and visual analytics—for the success of not only the CPS but also these two concepts—digitalization and machine intelligence.

    This thesis concludes by highlighting that currentdata and visual analytics approaches in CPS are closely dependent onthe availability, accessibility, quality, volume, and variety of the data. Notably, the huge amount of industrial data that exists in CPS manufacturers data repositories does not always mean that this data is useful, especially for analytical purposes. To this end, firstly, the CPS industry should concentrate its efforts to collect useful data that will benefit the industry by providing analytical insight intothe environments where CPS is produced and operated. Secondly, the industry should make necessary organizational changes such as considering to employ data scientists, analysts, and business intelligence developers and make data accessible tothese people for further usage. Thirdly, the data management procedures and data analytics roadmaps of companies should be created and shared with other employees, and necessary mechanisms needto be considered to improve and guarantee the quality of the data. Lastly, the variety of data needs to be addressed by the industry. 

    Data and visual analytics provides an opportunity to extract patterns; to evaluate the interoperability, complexity, and sustainability; to create an overview of the current challenge by providing different viewpoints adapted to different stakeholders, focusing on key concerns for the respective stakeholder; to optimize performance, automation, and cooperation of distributed CPS, development environment, and teams; and overall, to improve any of the challenges that are mentioned above by, basically, providing a better understanding.

    To this end, I suggest that the industry discuss the next step after digitalization and address the challenges related to the availability, accessibility, quality, volume, and variety of data by considering user-centric approaches and organizational needs of the future development and manufacturing environments. The CPS industry should plan and act on these challenges as part of its data analytics strategies to expedite the machine intelligence applications of the future.

    Proteomic approach for understanding milder neurotoxicity of Carfilzomib against Bortezomib2018Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 8, artikkel-id 16318Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The proteasomal system is responsible for the turnover of damaged proteins. Because of its important functions in oncogenesis, inhibiting the proteasomal system is a promising therapeutic approach for cancer treatment. Bortezomib (BTZ) is the first proteasome inhibitor approved by FDA for clinical applications. However neuropathic side effects are dose limiting for BTZ as many other chemotherapeutic agents. Therefore second-generation proteasome inhibitors have been developed including carfilzomib (CFZ). Aim of the present work was investigating the mechanisms of peripheral neuropathy triggered by the proteasome inhibitor BTZ and comparing the pathways affected by BTZ and CFZ, respectively. Neural stem cells, isolated from the cortex of E14 mouse embryos, were treated with BTZ and CFZ and mass spectrometry was used to compare the global protein pool of treated cells. BTZ was shown to cause more severe cytoskeletal damage, which is crucial in neural cell integrity. Excessive protein carbonylation and actin filament destabilization were also detected following BTZ treatment that was lower following CFZ treatment. Our data on cytoskeletal proteins, chaperone system, and protein oxidation may explain the milder neurotoxic effects of CFZ in clinical applications.

    Effects of Ga doping on magnetic and ferroelectric properties of multiferroic delafossite CuCrO2: Ab initio and Monte Carlo approaches2018Inngår i: Physical Review B, ISSN 2469-9950, E-ISSN 2469-9969, Vol. 98, nr 17, artikkel-id 174403Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The effects of nonmagnetic impurity doping on magnetic and ferroelectric properties of multiferroic delafossite CuCrO2 are investigated by means of density functional theory calculations and Monte Carlo simulations. Density functional theory calculations show that replacing up to 30% of Cr3+ ions by Ga3+ ones does not significantly affect the remaining Cr-Cr superexchange interactions. Monte Carlo simulations show that CuCr1-xGaxO2 preserves its magnetoelectric properties up to x similar or equal to 0.15 with a spiral ordering, while it becomes disordered at higher fractions. Antiferromagnetic transition shifts towards lower temperatures with increasing x and eventually disappears at x >= 0.2. Our simulations show that Ga3+ doping increases the Curie-Weiss temperature of CuCr1-xGaxO2, which agrees well with experimental observations. Moreover, our results show that the incommensurate ground-state configuration is destabilized by Ga3+ doping under zero applied field associated with an increase of frustration. Finally, coupling between noncollinear magnetic ordering and electric field is reported for x <= 0.15 through simulating P-E hysteresis loops, which leads to ferroelectricity in the extended inverse Dzyaloshinskii-Moriya model.

    Health literacy as knowledge construction: Learning about health by expanding objects and crossing boundaries in networked activities2018Inngår i: Learning, Culture and Social Interaction, ISSN 2210-6561, E-ISSN 2210-657XArtikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    In this paper we examine health literacy as a set of practices that unfold in networked activity systems. Focusing on the literacy practices of pregnant couples and parents of children with heart defect, we show that they participate in multiple activities with the object of constructing knowledge about the child's condition. The contexts for these activities are doctor-patient consultations and the parents' online searching and sharing. The study builds on ethnographic interviews, recorded medical consultations and collection of texts from online forums, blogs and social media. An analysis based on literacy practices and activity theory shows that these activities enable parents' learning, but they can also be restricting as to the mediating tools they provide and the rules that dictate the tools. Additionally, the object of learning about heart defect is not always clearly formulated and stable but it keeps alternating and expanding. As a result, the parents cross boundaries between activities with different mediating tools, rules and communities and thereby different possibilities for learning. We show that doing health literacy is comprised by a set of recontextualised practices of looking for medical and experiential knowledge and it is by a combination of the two that meaningful learning is achieved.

    Diffuse emissions to air and water2012Rapport (Annet vitenskapelig)
    Abstract [en]

    The Swedish environmental reporting system has large amounts of information regarding point source discharges. But, point sources represent only a limited part of the total discharges. Therefore contributions from diffuse sources are important to identify in relation to the spread of various substances to the environment. Ex-amples of diffuse sources include road traffic, agriculture, use of solvents, chemi-cals emitted from use-phase of products, and small industries. Here, these and simi-lar diffuse emissions to air are published in the Swedish Pollutant Release and Transfer Register (S-PRTR, with Swedish acronym UTIS). This data is derived from the air and climate reporting made to the Convention on Long-range Trans-boundary Air Pollution (CLRTAP) and UNFCCC. Data at the S-PRTR is listed for several organic pollutants, such as PAHs and heavy metals. Data on diffuse emis-sions to water is currently not provided at the S-PRTR website. Certain diffuse emissions into water are included in the international emission reporting, such as the HELCOM PLC periodical and EEA WISE SoE Emissions.

    The project described herein is based on the development project "Feasibility study for possible publication of diffuse emissions at SPRTR, and is designed to:

     Publish data on emissions from diffuse sources, primarily to water, from selected sectors and substances or substance groups.

     Compare data collected for these diffuse emissions in relation to totals for data reported to E-PRTR.

     Based on the knowledge acquired during this project to propose more regu-lar procedures for collecting data regarding diffuse emissions.

    Substances considered in the project include nutrients (nitrogen and phosphorus), metals (lead, cadmium, copper, mercury, nickel and zinc) and certain organic com-pounds (PAHs, PBDEs, nonylphenols, PCBs, HCHs, DDT, endosulfan, and diox-ins. There is currently no data in certain matrices for these organic pollutants.

    The project has four separate subprojects:

     Diffuse emissions of metals and nutrients to water.Diffuse emissions of certain organic pollutants to water.Diffuse emissions of nonylphenols and nonylphenol ethoxylates from different product groups.Analyses of report-ed data for air and water, and comparison with diffuse emissions.Project 1 covers the following diffuse sources: atmospheric deposition on water, forest land, agriculture, other land, stormwater, local on-site wastewater treatment facilities, industrial facilities and wastewater treatment plants not included in reporting to E-PRTR. Copper is also considered as emission from antifouling boat paint. Subpro-ject 1 findings show that the most significant emission source for nitrogen and phosphorus is agricultural and forests land. Forests dominate as the source of all metals. As well, diffuse emissions of most other metal are significant from agricul-ture, deposition on water, other land and stormwater. Geographically, distribution of emissions shows that stormwater is more significant in the south (Northern Baltic, Southern Baltic, and Skagerrak and Kattegat river basin districts) than in the north (Bothnian Bay and Bothnian Sea river basin districts). This is as expected due to greater traffic volumes in the south. In future, data from water load reporting can be easily recalculated in the geo-database to match publication in the E-PRTR. Coordinating with departments producing water emission statistics is necessary, though.

    Subproject 2 findings show that data for only a few organic pollutants is currently available (such as PAHs, PBDEs, nonylphenols, dioxins, DEHP, PCBs, HCH, DDT, endosulfan and chlorinated paraffins). Data for many of these substances is available only for single or a few diffuse sources (small industries and WWTPs, deposition on water, stormwater and deposition on land). Data for diffuse emis-sions of organic pollutants that is currently available are uncertain and based on few measurements.

    Subproject 3 shows that it is possible to estimate nonylphenols (NPequ) emissions to air, soil and wastewater. The largest source of NPequ to wastewater is from textiles, while smaller amounts are from detergents. The data are uncertain, however, as they are based on emission factors with significant uncertainties.

    Finally,subproject 4 findings show that all diffuse emissions are significant. Dif-fuse emission of nitrogen, phosphorus and metals to water is at least 10 times or more larger compared to point sources, in nearly all cases. Agricultural land domi-nates as a source in the case of phosphorus and nitrogen. Emissions of organic pollutants to water show significant gaps in the data because very few companies report emissions.

    Regarding emissions of organic pollutants and metals to the air, the difference between point sources (E-PRTR) and diffuse emissions based on data from CLRTAP are in most cases not as great as for water. For copper, diffuse emissions to air from brake linings is the largest source of diffuse emission (>90%). And for PAH, diffuse emissions from the energy sector dominates, corresponding to nearly 100% of the total. Emissions of each pollutant (nearly all) is greater to water than to air for point sources, diffuse sources, and the total.

    When comparing emissions from various industries, findings show that forestry industry facilities contribute approximately 90% when it comes to cadmium emis-sions to water from point sources according to E-PRTR (total 440 kg). Still, this is much lower than diffuse emissions as found in Subproject 1, 3,900 kg – indicating diffuse emissions are nearly 9 times greater. The difference for emissions to water is not very large between point sources reported to E-PRTR and those not (in the e-PRTR) – indicating that the point sources under E-PRTR include a large portion of all discharges from point sources to water.

    The quality of data is sufficient to show diffuse emission levels of nutrients and metals at the S-PRTR, reported for the national, river basin district or more refined levels, since this data is based on values reported to the EU and HELCOM. Re-garding organic pollutants to water and nonylphenols from products, the data is more uncertain and is therefore not recommended to be published in the S-PRTR. For emissions to air, our conclusion is that national totals, as reported to the UNPCCC and CLRTAP can be included in the S-PRTR.

    Association of body mass index and age With subsequent breast cancer risk in premenopausal women2018Inngår i: JAMA Oncology, ISSN 2374-2437, E-ISSN 2374-2445, Vol. 4, nr 11, artikkel-id e181771Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    IMPORTANCE The association between increasing body mass index (BMI; calculated as wei ght in kilograms divided by height in meters squared) and risk of breast cancer is unique in cancer epidemiology in that a crossover effect exists, with risk reduction before and risk increase after menopause. The inverse association with premenopausal breast cancer risk is poorly characterized but might be important in the understanding of breast cancer causation.

    OBJECTIVE To investigate the association of BMI with premenopausal breast cancer risk, in particular by age at BMI, attained age, risk factors for breast cancer, and tumor characteristics.

    DESIGN, SETTING, AND PARTICIPANTS This multicenter analysis used pooled individual-level data from 758 592 premenopausal women from 19 prospective cohorts to estimate hazard ratios (HRs) of premenopausal breast cancer in association with BMI from ages 18 through 54 years using Cox proportional hazards regression analysis. Median follow-up was 9.3 years (interquartile range, 4.9-13.5 years) per participant, with 13 082 incident cases of breast cancer. Participants were recruited from January 1,1963, through December 31, 2013, and data were analyzed from September 1.2013, through December 31, 2017.

    EXPOSURES Body mass index at ages 18 to 24, 25 to 34,35 to 44, and 45 to 54 years.

    MAIN OUTCOMES AND MEASURES Invasive or in situ premenopausal breast cancer.

    RESULTS Among the 758 592 premenopausal women (median age, 40.6 years; interquartile range, 35.2-45.5 years) included in the analysis, inverse linear associations of BMI with breast cancer risk were found that were stronger for BMI at ages 18 to 24 years (HR per 5 kg/m(2) [5.0-U] difference, 0.77; 95% CI, 0.73-0.80) than for BMI at ages 45 to 54 years (HR per 5.0-U difference, 0.88; 95% CI, 0.86-0.91). The inverse associations were observed even among nonoverweight women. There was a 4.2-fold risk gradient between the highest and lowest BMI categories (BMI >= 35.0 vs <17.0) at ages 18 to 24 years (HR, 0.24; 95% CI, 0.14-0.40). Hazard ratios did not appreciably vary by attained age or between strata of other breast cancer risk factors. Associations were stronger for estrogen receptor-positive and/or progesterone receptor-positive than for hormone receptor-negative breast cancer for BMI at every age group (eg, for BMI at age 18 to 24 years: HR per 5.0-U difference for estrogen receptor-positive and progesterone receptor-positive tumors, 0.76 [95% CI, 0.70-0.81] vs hormone receptor-negative tumors, 0.85 [95% CI: 0.76-0.95]); BMI at ages 25 to 54 years was not consistently associated with triple-negative or hormone receptor-negative breast cancer overall.

    CONCLUSIONS AND RELEVANCE The results of this study suggest that increased adiposity is associated with a reduced risk of premenopausal breast cancer at a greater magnitude than previously shown and across the entire distribution of BMI. The strongest associations of risk were observed for BMI in early adulthood. Understanding the biological mechanisms underlying these associations could have important preventive potential.

    Samband mellan sjukdomar och äldre bilförares inblandning i trafikolyckor2018Rapport (Annet vitenskapelig)
    Abstract [sv]

    Sverige är ett av få länder inom EU som inte har obligatoriska hälsokontroller för förare över en viss ålder. Vår motivering är att man inte kunnat påvisa positiva trafiksäkerhetseffekter av sådana kontroller. Den här studien utreder om personbilsförare som är 65 år eller äldre och som har en sjukdomsdiagnos oftare är inblandade i trafikolyckor jämfört med förare i samma ålder och utan diagnos. 

    Forskningsstudien har sin utgångspunkt i de trafikmedicinska föreskrifterna och de 13 diagnosgrupperna som beskrivs i föreskrifternas olika kapitel. För att undersöka om äldre bilförare med en sjukdomsdiagnos har högre olycksrisk än äldre bilförare utan diagnos har vi matchat en fallpopulation på 13 700 olycksinblandade förare som var 65 år eller äldre med en kontrollgrupp. Kontrollgruppen bestod av 26 500 åldersmatchade personer som skulle uppfylla tre krav: ha giltigt B-körkort (personbil), vara bilägare och inte ha varit inblandade i någon trafikolycka. 

    De register som vi använt oss av är 

     Transportstyrelsens olycksdatabas Strada

     Statistiska centralbyråns befolkningsregister

     Socialstyrelsens patientregister.

    Studien begränsas av ett antal faktorer, till exempel att vi saknar uppgift om exponering i trafik och föreskrivna läkemedel, för att nämna några. Det här innebär bland annat att vi inte kan säga om en t. ex. förhöjd sannolikhet för olycka beror på försämrad körförmåga eller att man kör mer bil och att man därmed är mer exponerad i trafiken.

    PRTR and synergies with other multilateral agreements, EU legal acts and EEA reportings2014Rapport (Annet vitenskapelig)
    Abstract [en]

    Swedish Environmental Emissions Data (SMED) has, on behalf of the Swedish Environmental Protection Agency (Swedish EPA) compiled an overview of the multilateral agreements, EU legal acts and EEA reports, which is listed in Table 1, together with identified similarities and differences between these and the UNECE (United Nations Economic Commission for Europe) Protocol on Pollutant Release and Transfer Register, i.e. the PRTR Protocol.

    Relevant general information regarding each agreement has been collected from the Internet and, based on the summarized information, possible synergies with the PRTR protocol have been analyzed.

    The study shows that there are synergies between regulations that are included in the project and the PRTR. Furthermore, the results also show that even though similarities can be identified, each regulation requires different information and is thus unique. In Table 2, identified general synergies are presented, and it can be concluded that the regulations that have most in common with the PRTR protocol are the Minamata Convention and the Industrial Emissions Directive.

    The Neuropeptide Y System Regulates Both Mechanical and Histaminergic Itch2018Inngår i: Journal of Investigative Dermatology, ISSN 0022-202X, E-ISSN 1523-1747, Vol. 138, nr 11, s. 2405-2411Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Itch is a somatosensory modality that serves to alert an organism to harmful elements removable by scratching, such as parasites and chemical irritants. Recently, ablation or silencing of neuropeptide Y (NPY)-expressing spinal interneurons was reported to selectively enhance mechanical itch, whereas chemical itch was unaffected. We examined the effect of activating the NPY/Y-1 receptor system on scratch behavior in mice. We found that intrathecal administration of the Y-1 agonist [Leu(31), Pro(34)]-NPY (LP-NPY) attenuated itch behavior induced by application of 0.07 g von Frey filament in the nape of the neck compared with saline treatment, indicating that activation of the spinal NPY/Y-1 system dampens mechanical itch. However, intrathecal administration of LP-NPY also attenuated chemically induced scratching provoked by intradermal application of histamine or the mast cell degranulator 48/80 (histaminergic itch), and the latter effect could be reversed by administration of the Y-1 antagonist BIBO3304. Intrathecal application of the native nonselective agonist NPY also attenuated histamine or 48/80-induced scratching. Our analyses emphasize the importance of including additional quantitative parameters to characterize the full spectrum of itch behavior and show that the NPY/Y-1 system dampens both mechanically and chemically induced scratching and hence is shared by the two submodalities of itch.

    Role of the orbital moment in a series of isostructural weak ferromagnets2018Inngår i: Physical Review B, ISSN 2469-9950, E-ISSN 2469-9969, Vol. 98, nr 10, artikkel-id 104424Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The orbital contribution to the magnetic moment of the transition-metal ion in the isostructural weak ferromagnets ACO(3) (A = Mn,Co,Ni) and FeBO3 was investigated by a combination of first-principles calculations, nonresonant x-ray magnetic scattering, and x-ray magnetic circular dichroism. A nontrivial evolution of the orbital moment as a function of the 3d orbitals filling is revealed, with a particularly large value found in the Co member of the family. Here, the coupling between magnetic and lattice degrees of freedom produced by the spin-orbit interaction results in a large single-ion anisotropy and a peculiar magnetic-moment-induced electron cloud distortion, evidenced by the appearance of a subtle scattering amplitude at space-group-forbidden reflections and significant magnetostrictive effects. Our results, which complement a previous investigation on the sign of the Dzyaloshinskii-Moriya interaction across the series, highlight the importance of spin-orbit coupling in the physics of weak ferromagnets and prove the ability of modern first-principles calculations to predict the properties of materials where the Dzyaloshinskii-Moriya interaction is a fundamental ingredient of the magnetic Hamiltonian.

    Aerobic Variables for Prediction of Alpine Skiing Performance: A Novel Approach2018Inngår i: Sports Medicine International Open, ISSN 2367-1890, Vol. 2, nr 4, s. 105-112Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to investigate the predictive power of aerobic test results and anthropometric variables on FIS-ranking of junior elite alpine skiers. Results from twenty-three male and female adolescent elite alpine skiers from two seasons were included in the multivariate statistical models. Physical work capacity was determined by V̇O2peak, blood lactate concentration ([HLa]b), and heart rate (HR) during ergometer cycling. Anthropometric variables were body stature, body weight and calculated BMI. No significant correlation between competitive performance and aerobic work capacity or anthropometric data was observed neither in male nor female adolescent skiers. Pre-season physical tests and anthropometric data could therefore not predict end-season FIS-ranking. The best regression (R2) and prediction (Q2) models of FIS slalom (SL) and giant slalom (GS) rank reached R2=0.51 to 0.86, Q2=−0.73 to 0.18, indicating no valid models. This study could not establish V̇O2peak and other included variables as predictors of competitive performance. When combining results from commonly used tests for alpine skiers, and applying multivariate statistical models, investigated tests seems of limited used for athletes, coaches, and ski federations. Performance-specific pre-season tests must be developed and validated for prediction of performance and guidance of exercise training.

    One size fits none: a qualitative study investigating nine national quality registries' conditions for use in quality improvement, research and interaction with patients2018Inngår i: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 18, artikkel-id 802Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Swedish National Quality Registries (NQRs) are observational clinical registries that have long been seen as an underused resource for research and quality improvement (QI) in health care. In recent years, NQRs have also been recognised as an area where patients can be involved, contributing with self-reported experiences and estimations of health effects. This study aimed to investigate what the registry management perceived as barriers and facilitators for the use of NQRs in QI, research, and interaction with patients, and main activities undertaken to enhance their use for these purposes. The aim was further to identify potential differences between various types of NQRs for their use in these areas.

    Methods: In this multiple case study, nine NQRs were purposively selected. Interviews (n = 18) were conducted and analysed iteratively using conventional and directed content analysis.

    Results: A recent national investment initiative enabled more intensive work with development areas previously identified by the NQR management teams. The recent focus on value-based health care and other contemporary national healthcare investments aiming at QI and public benchmarking were perceived as facilitating factors. Having to perform double registrations due to shortcomings in digital systems was perceived as a barrier, as was the lack of authority on behalf of the registry management to request participation in NQRs and QI activities based on registry outcomes. The registry management teams used three strategies to enhance the use of NQRs: ensuring registering of correct and complete data, ensuring updated and understandable information available for patients, clinicians, researchers and others stakeholders, and intensifying cooperation with them. Varied characteristics of the NQRs influenced their use, and the possibility to reach various end-users was connected to the focus area and context of the NQRs.

    Conclusions: The recent national investment initiative contributed to already ongoing work to strengthen the use of NQRs. To further increase the use, the demands of stakeholders and end-users must be in focus, but also an understanding of the NQRs' various characteristics and challenges. The end-users may have in common a need for training in the methodology of registry based research and benchmarking, and how to be more patient-centred.

    PRTR och synergier med andra multilaterala överenskommelser, EU-rättsakter och EEA-rapporteringar2014Rapport (Annet vitenskapelig)
    Abstract [sv]

    Svenska MiljöEmissionsData (SMED) har på uppdrag av Naturvårdsverket (NV) sammanställt övergripande information om de multilaterala överenskommelser, EU-rättsakter och EEA-rapporteringar som listas i Tabell 1, samt identifierat huruvida det finns beröringspunkter respektive avvikelser mellan dessa och UNECE (United Nations Economic Commission for Europe) -protokollet om "Pollutant Release and Transfer Register", dvs. PRTR-protokollet.

    Relevant övergripande information för respektive reglering har sammanställts från Internet och utifrån dessa sammanställningar har eventuella synergier med PRTR-protokollet analyserats.

    Studien visar att det finns synergier mellan de regleringar som inkluderats i projektet och med PRTR. Samtidigt visar studien att även om man kan identifiera beröringspunkter så efterfrågas inte exakt samma information utan samtliga regleringar är unika. I Tabell 2 redovisas identifierade övergripande synergier och man konstatera att de regleringar som PRTR-protokollet har flest antal beröringspunkter med är Minamatakonventionen och Industriutsläppsdirektivet (IED).

    Perpetuating harms from isolation among older adults with cognitive impairment: observed discrepancies in homecare service documentation, assessment and approval practices2018Inngår i: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 18, artikkel-id 800Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Older persons with cognitive impairment (CI) risk social isolation. Strong evidence shows that perceived loneliness, or inadequate social networks, triggers and increases health problems. How homecare systems address social participation remains unknown; anecdotal data suggests there are significant gaps. This study's objective was to identify and describe how the assessors of homecare needs document social participation among persons with CI and how their documentation corresponds with the services actually provided to meet social needs. The research questions were: How and what kinds of social participation needs are documented on need assessment forms? What types of homecare services (with a social focus) are documented and approved? How are specified needs in social participation profiles addressed by a homecare service?

    Methods: Descriptive data from need assessment forms and their attached care plans for all applicants aged 65+ were collected during a 2 month period from a large homecare agency serving a municipality in Sweden. Persons with documented CI (n = 43) in the group were identified. Qualitative data analysis was conducted to examine the research questions.

    Results: Social participation factors were not documented consistently. The relationship between recognition of limitations to social participation and approval of service eligibility was not consistent. Social participation was designated by references to social status, sometimes by social network size, and occasionally by limitations to social participation. The range of approved homecare services (with social focus) covered services such as day care center visits or companionship. Three profiles of social participation were identified: clients with, (a) no participation limitations; (b) potential limitations; and (c) marked limitations.

    Conclusion: Given the known health harms from social isolation and the high risk of isolation among older persons with CI, this novel study's documentation of inadequate and inconsistent information in homecare social need assessments and services is sobering. The findings suggest a pressing need for initiatives to formulate best practices and standards to ensure alignment of care service systems to the health needs of the growing group of aging individuals with CI.

    Student Involvement as a Tool for Nurturing Business Model Development in Tourism Businesses in the Stockholm Archipelago2018Inngår i: Academica Turistica - Tourism and Innovation Journal, ISSN 2335-4194, Vol. 11, nr 1, s. 73-86Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Tourism consumption in Sweden is booming, but it seems to be at a standstill in the Stockholm archipelago, and most businesses of all kinds in it are small. Therefore, an eu-Interreg-financed educational community engagement project aiming at business model development in the archipelagos of Turku, Åland (both in Finland), and Stockholm was launched, as Finland has a similar situation. In this paper, the foundations of the project, the literature on the issues of being rural and in the archipelago, and business models are reviewed and put in perspective through preliminary empirical results of the project, in while municipality and some business representatives have been interviewed. The rationale is that there is a weak scientific understanding of business models in use in the archipelagos. Methodologically, action research is being used in addition to document studies, with unstructured interviews and observations as the primary empirical methods. The primary results for which the empirical findings put light on the intersection of the abovementioned literature bodies are the impact of infrastructural and access problems due to isolation, as well as indications of a community split between second homes and permanent residents. The lifestyle-entrepreneurship jeopardises the economic well-being but enriches the social well-being of the population. The primary conclusions are that seasonality and second homers provide entrepreneurs with large output markets in season, but small ones in the off-season. The business equation cannot omit place since it is part of the social well-being of the lifestyle-entrepreneurs, which calls for further research into configurational approaches to strategy in an archipelago context.

    Sustainability-oriented Future EU Funding: A Fuel Tax Surcharge2018Rapport (Fagfellevurdert)
    Abstract [en]

    The paper analyses the potential of a surcharge on national fuel taxes as sustainability-oriented own resource to finance the EU budget. Our estimations show that such a surcharge could yield substantial revenues, ranging between € 12.93 billion (for a surcharge of 0.03 €) and 86.2 billion (for a surcharge of 0.2 €) per year. Besides the contribution an EU fuel tax would make to various sustainability-related EU goals and strategies, it would help to address two specific problems inherent in the current EU system of fuel taxation. An EU fuel tax designed as a surcharge on national fuel taxes would decrease the existing tax bias in favour of diesel, as the surcharge would be levied uniformly on gasoline and diesel, which in most EU Member States is taxed at lower rates, alike. Moreover, by increasing national fuel tax rates, the surcharge would – depending on its level – mitigate or even remove the “under-taxation” of fuel in relation to the minimum fuel tax rates stipulated in the EU Energy Tax Directive in a number of Member States, which is caused by the absence of regular inflation adjustment of nominal fuel tax rates.

    A two-nuclease pathway involving RNase H1 is required for primer removal at human mitochondrial OriL2018Inngår i: Nucleic Acids Research, ISSN 0305-1048, E-ISSN 1362-4962, Vol. 46, nr 18, s. 9471-9483Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The role of Ribonuclease H1 (RNase H1) during primer removal and ligation at the mitochondrial origin of light-strand DNA synthesis (OriL) is a key, yet poorly understood, step in mitochondrial DNA maintenance. Here, we reconstitute the replication cycle of L-strand synthesis in vitro using recombinant mitochondrial proteins and model OriL substrates. The process begins with initiation of DNA replication at OriL and ends with primer removal and ligation. We find that RNase H1 partially removes the primer, leaving behind the last one to three ribonucleotides. These 5′-end ribonucleotides disturb ligation, a conclusion which is supported by analysis of RNase H1-deficient patient cells. A second nuclease is therefore required to remove the last ribonucleotides and we demonstrate that Flap endonuclease 1 (FEN1) can execute this function in vitro. Removal of RNA primers at OriL thus depends on a two-nuclease model, which in addition to RNase H1 requires FEN1 or a FEN1-like activity. These findings define the role of RNase H1 at OriL and help to explain the pathogenic consequences of disease causing mutations in RNase H1.

    Prompt and non-prompt J/psi and psi(2S) suppression at high transverse momentum in 5.02 TeV Pb+Pb collisions with the ATLAS experiment2018Inngår i: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 78, nr 9, artikkel-id 762Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A measurement of J/psi and psi(2S) production is presented. It is based on a data sample from Pb+Pb collisions at root s(NN) = 5.02 TeV and pp collisions at root s = 5.02 TeV recorded by the ATLAS detector at the LHC in 2015, corresponding to an integrated luminosity of 0.42 nb(-1) and 25 pb(-1) in Pb+Pb and pp, respectively. The measurements of per-event yields, nuclear modification factors, and non-prompt fractions are performed in the dimuon decay channel for 9 < p(T)(mu mu) < 40 GeV in dimuon transverse momentum, and -2 < y(mu mu) < 2 in rapidity. Strong suppression is found in Pb+Pb collisions for both prompt and non-prompt J/psi, increasing with event centrality. The suppression of prompt psi(2S) is observed to be stronger than that of J/psi, while the suppression of non-prompt psi(2S) is equal to that of the non-prompt J/psi within uncertainties, consistent with the expectation that both arise from b-quarks propagating through the medium. Despite prompt and non-prompt J/psi arising from different mechanisms, the dependence of their nuclear modification factors on centrality is found to be quite similar.

    Leaf wax delta D inferring variable medieval hydroclimate and early initiation of Little Ice Age (LIA) dryness in southern Mozambique2018Inngår i: Global and Planetary Change, ISSN 0921-8181, E-ISSN 1872-6364, Vol. 170, s. 221-233Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A sediment sequence from a coastal, hydrologically isolated lake in southern Mozambique was analysed for leaf wax delta D, n-alkane abundance (ACL) and bulk organic geochemistry (delta C-13, TOC, %N), providing a record of past rainfall variability and savanna dynamics over the last 1500 years. The delta D-wax a rainfall reconstruction reveals a stable hydroclimate between 500-700 CE, while ACL and delta C-13 together with previous pollen data suggest savanna vegetation was characterized by a relatively dense woody cover. Highly variable hydroclimate conditions are inferred by delta D-wax between 800-1350 CE, with repeated centennial scale intervals of extreme dry and wet conditions overlapping the Medieval Climate Anomaly (MCA; 950-1250 CE). Savanna tree cover stayed relatively intact over this phase. After ca 1250 CE, a progressive change towards drier conditions was initiated, leading up to maximum aridity during the AD 1700s, a period associated with the Little Ice age (LIA; 1500-1850 CE). Tree cover was now replaced by a more grass-dominated savanna. The clear antiphase rainfall patterns between Nhaucati and equatorial East African proxy records gives support to the notion that Indian Ocean sea surface temperature (SST) gradients act as modulator of southern African climate on a multi-decadal time scale, possibly forced by long-term El Nino Southern Oscillation (ENSO) variability. We suggest that strong ENSO variability and greater occurrence of La Nina events triggered the generally wet and unstable MCA in southern Africa. From around 1250 CE, a shift towards a predominance of El Nino induced drier conditions in south-east Africa during the LIA. Our study of vegetation and hydroclimate proxies in parallel suggests that savanna tree and shrub cover was relatively resilient to the abrupt shifts in hydroclimate over the MCA, but more sensitive to the long-term progressive drying over the LIA.

    Multilocus phylogeny of the parasitic wasps in the tribe Euphorini (Hymenoptera: Braconidae) with revised generic classifications2018Inngår i: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, artikkel-id 6:e4783Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background. Parasitic wasps in the family Braconidae are important regulators of

    insect pests, particularly in forest and agroecosystems. Within Braconidae, wasps in the

    tribe Euphorini (Euphorinae) attack economically damaging plant bugs (Miridae) that

    are major pests of field and vegetable crops. However, the evolutionary relationships

    of this tribe have been historically problematic. Most generic concepts have been

    based on ambiguous morphological characters which often leads to misidentification,

    complicating their use in biological control.

    Methods. Using a combination of three genes (COI, 28S, and CAD) and 80 taxa

    collected worldwide, we conducted Bayesian inference using MrBayes, and maximum

    likelihood analyses using RAxML and IQ-Tree on individual gene trees as well as the

    concatenated dataset.

    Results. The monophyly of the tribe Euphorini and the two genera Peristenus and

    Leiophron were confirmed using maximum likelihood and Bayesian inference. The subgeneric

    classifications of Leiophron sensu lato were not supported, and the monotypic

    genus Mama was also not supported.

    Discussion. Euphoriella, Euphoriana, Euphorus, and Mama syn. n, have been synonymized

    under Leiophron. Mama mariae syn. n was placed as a junior synonym of

    Leiophron reclinator. The generic concepts of Peristenus and Leiophron were refined to

    reflect the updated phylogeny. Further we discuss the need for revising Euphorini given

    the number of undescribed species within the tribe.

    Complexity and stability of ecological networks: a review of the theory2018Inngår i: Population Ecology, ISSN 1438-3896, E-ISSN 1438-390X, Vol. 60, nr 4, s. 319-345Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Our planet is changing at paces never observed before. Species extinction is happening at faster rates than ever, greatly exceeding the five mass extinctions in the fossil record. Nevertheless, our lives are strongly based on services provided by ecosystems, thus the responses to global change of our natural heritage are of immediate concern. Understanding the relationship between complexity and stability of ecosystems is of key importance for the maintenance of the balance of human growth and the conservation of all the natural services that ecosystems provide. Mathematical network models can be used to simplify the vast complexity of the real world, to formally describe and investigate ecological phenomena, and to understand ecosystems propensity of returning to its functioning regime after a stress or a perturbation. The use of ecological-network models to study the relationship between complexity and stability of natural ecosystems is the focus of this review. The concept of ecological networks and their characteristics are first introduced, followed by central and occasionally contrasting definitions of complexity and stability. The literature on the relationship between complexity and stability in different types of models and in real ecosystems is then reviewed, highlighting the theoretical debate and the lack of consensual agreement. The summary of the importance of this line of research for the successful management and conservation of biodiversity and ecosystem services concludes the review.

    Abstract [en]

    This volume collects 11 selected papers from the scientific contributions presented at the Ninth Congress of the International Society for Theoretical Chemical Physics (ISTCP-IX), organized by the team led by Professor Mark Hoffmann at the University of North Dakota, Grand Forks, North Dakota, U.S.A., from July 17 to 22, 2016. The ISTCP-IX Congress in Grand Forks followed the format established at the eight previous meetings:

     

    ISTCP-I:               Professor Ramon Carbo-Dorca, Girona (Spain), June 28 - July 3, 1993

    ISTCP-II:             Professor Sean P. McGlynn, New Orleans (LA, USA), April 9 - 13, 1996

    ISTCP-III:            Professor Miguel Castro, Mexico City (DF, Mexico), November 8 - 13, 1999

    ISTCP-IV:            Professor Jean Maruani, Marly-le-Roi (Paris, France), July 9 - 16, 2002

    ISTCP-V:             Professor Peter Politzer, New Orleans (LA, USA), July 20 - 26, 2005

    ISTCP-VI :           Professor Yan Alexander Wang, Vancouver (BC, Canada), July 19 - 24, 2008

    ISTCP-VI I:          Professor Hiromi Nakai, Waseda (Tokyo, Japan), September 2 - 8, 2011

    ISTCP-VIII:         Professor Péter Surján, Eötvös (Budapest, Hungary), August 25 – 31, 2013.

     

     

    The 2016 venue offered the possibility for the approximately 300 participants from 26 countries to join the Congress. Speakers from each of the countries were joined by students from 9 countries.  Despite being nearly 2000 km from any sea coast (1200 km, if one counts the Arctic Ocean outlet Hudson Bay),  this Congress continued to reflect the strong international characteristics of ISTCP. Countries sending 4 or more delegates include China, Denmark, France, Germany, Hungary, Israel, Japan, Mexico, Netherlands, Norway, Switzerland, and the United Kingdom, besides the U.S.A.

     

    The International Society for Theoretical Chemical Physics, ISTCP, was founded in 1990 by Professor János Ladik at the University of Erlangen, Germany. ISTCP has the objectives to promote theoretical developments at the frontier between physics and chemistry. Additionally the goal is to allow younger researchers to interact with leading contributors of the field at regularly organized International Congresses. The Society involves an Honorary Board, a Board of Directors gathering together about 60 scientists (including 5 Nobel Laureates and 2 Wolf Prize laureates) in the fields of Theoretical Chemistry and Physics, and a Board of National Representatives covering about 35 countries/regions. The current President, since July 2000, is Professor Erkki J. Brändas, from Uppsala University, Sweden.

     

    ISTCP Congress Proceedings have been published regularly in the special issues of the International Journal of Quantum Chemistry (IJQC) and partly (2002, 2008) co-published in special volumes of Progress in Theoretical Chemistry and Physics (PTCP). Following this tradition, a small and highly targeted set of articles were solicited from researchers in several forefront fields represented at ISTCP IX.  These 11 articles are divided into 4 reviews, 3 tutorial reviews, 2 perspectives and 2 papers.

     

    ISTCP-IX was organized into 9 thematic Symposia, plus a special symposium honouring Per-Olov Löwdin.  The co-organizers of each of the symposia had significant latitude in inviting leading scientists in their areas, with attention paid to overall geographical, career stage and gender diversity.  Moreover, in an effort to stimulate conversation and cross-disciplinary inquiries, each speaker was limited to only 1 talk, and there were never more than 3 parallel sessions.  It is the careful thought and hard work of the Symposium Organizers that contributed to the success of the Congress.  The Symposia and their Organizers are:

     

     1. Accurate Thermochemistry (Angela Wilson, Branko Ruscic)

     2. Chemical Insights (Paul Ayers, Pedro Salvador)

     3. Complex Systems (Jiali Gao, Nandini Ananth)

     4. Dynamics (George Schatz, Keli Han)

     5. Electronic Structure (Piotr Piecuch, Jiri Pittner)

     6. Subsystems in Density Functional Theory (Tomasz Wesolowski, Christoph Jacob)

     7. Emerging Methods for Quantum N-body Problem (Seiichiro Ten-no, Edward Valeev)

      8. Molecular Properties (Trygve Helgaker)

      9. Per-Olov Löwdin Symposium (Erkki Brändas)

    10. Relativistic Methods (Wenjian Liu, Jochen Autschbach)

     

    In addition to symposia, there were 9 plenary talks for which all participants were gathered.  The early and enthusiastic support of the plenary speakers were critical to providing high visibility for the conference, and we are grateful to them.

    1. Kim Baldridge, Structure-Property Relationships of Curved Aromatic Materials from First Principles

    2. Ria Broer, Theoretical and Computational Studies for the Design of Organic Photovoltaic Materials

    3. Benedetta Mennucci, Ab Initio Simulation of the Optical Spectroscopy of Multichromophoric Systems

    4. William Miller, Symmetrical Quasi-Classical Model for Classical Molecular Dynamics Simulations of Electronically Non-adiabatic Processes

    5. Debashis Mukherjee, A Survey of the Unitary Group Adapted MRCC and MRPT Theories: SU vs SS Approaches

    6. Martin Quack, The Quantum Dynamics of Chiral and Achiral Molecules including Electroweak Parity Violation: Theory and Experiment

    7. Andreas Savin, Multireference Density Functional Theory

    8. Henry F. Schaefer III

    9. Tamar Seideman, Coherent Alignment in Complex Systems

     

    This Preface does not allow a comprehensive account of all the excellent contributions to the conference or to the articles submitted to these proceedings. The 4 Reviews consider relativistic treatment of molecular properties, charge transfer in molecular crystals and in organic polymeric materials, and advances in subsystem embedding.  These are complemented by Tutorial Reviews on molecular motors, the inverse approach to exchange-correlation potentials, and the random phase approach in the context of reduced density matrices.  One full paper considers the chemistry of new super heavy elements and the other on data considerations in petascale computations of chemical and biological systems.  There are Perspectives on non-collinear electronic structure calculations and calculations of atoms and molecules in strong magnetic fields.  The articles in the proceedings can be grouped roughly into extension of theory and calculations into much larger systems than could be considered just a few years ago and extension of precision in theory and calculations.

     

    We are grateful to all organizers for their exceptional work. In particular we want to thank Professor Janos Ladik, Founder of the Society and Honorary Chair. We were sorry to learn that he could not participate in person but his kind interest and strong support in the various matters of the venue were indeed a positive factor. We are indebted to our excellent organizing committee that guided us in producing a well-balanced, global perspective on cutting-edge chemical physics: Gustavo Aucar, T. Daniel Crawford, Peter Gill, Anna Krylov, Hiromi Nakai, Katarzyna Pernal, Péter Surján and Ágnes Szabados. We are also grateful to all session chairs, speakers, poster presenters, as well as all student volunteers, contributing significantly to the great success of the meeting. For more details regarding the Congress we refer to our web site http://istcp-2016.org/.

     

    The ISTCP-IX Congress took place at the Alerus Center, near the University of North Dakota campus. The assistance of the staff at the Alerus Center and at the Greater Grand Forks Convention and Visitors Bureau were critical in facilitating an event of this complexity in this city of only 60,000 people.  But, most of all, it was the unwavering support of former UND President Robert Kelley, Vice President of Academic Affairs and Provost Tom DiLorenzo, Vice President for Research and Economic Development Grant McGimpsey, and Division of Research Staff Cathy Lerud and Carla Kellner that made this happen.

     

    We are pleased to express our sincere thanks to our sponsors.  In addition to generous support from the University of North Dakota and the Greater Grand Forks Convention and Visitors Bureau, which allowed low-cost registration and accommodations for students, we are pleased to be able to acknowledge additional support from Physical Chemistry Chemical Physics and Department of Energy. These contributions from our sponsors have enabled us to maintain the high-quality standard of the Congress.

     

    The guest editors of this Special Issue, finally, want to thank the authors, who accepted our invitation to contribute to these proceedings, and in so doing provide a perspective of some cutting edge areas of inquiry in chemical physics.  The IXth Congress of ISTCP included both these areas and many more. We hope that all researchers with a great interest in theory and methods related to fundamental scientific problems and future progress of our field will appreciate this volume.

    Review of the genus Townesilitus (Haeselbarth & Loan) in Sweden, with a molecular characterization.2017Inngår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 138, nr 2, s. 137-150Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The tribe Townesilitini (Braconidae, Euphorinae) includes the genera Townesilitus, Streblocera,

    Marshiella and Prochlithrophorus. In Sweden this tribe is represented by the genera

    Townesilitus and Streblocera. This paper explores the taxonomy of the genus Townesilitus

    in Sweden. One new species is described from Sweden, Townesilitus oelandicus sp.

    nov. and the species T. aemulus (Ruthe, 1856) is recorded for the first time for Sweden. All

    five Swedish species, T. aemulus (Ruthe, 1856), T. bicolor (Wesmael, 1835), T. deceptor

    (Wesmael, 1835), T. fulviceps (Ruthe, 1856) and T. oelandicus, are diagnosed both morphologically and molecularly. A key for the identification of these species is provided and

    a phylogenetic tree is presented as well as information on distribution and phenology for

    all five species occurring in Sweden.

    Extraction of Polarization Parameters in the ‾pp → Ω̄Ω Reaction2018Inngår i: FAIRNESS 2017: Fair Next Generation Scientists 2017, 2018, artikkel-id UNSP 012019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    A method to extract the polarization of Omega hyperons produced via the strong interaction is presented. Assuming they are spin 3/2 particles, the corresponding spin density matrix can be written in terms of seven non-zero polarization parameters, all retrievable from the angular distribution of the decay products. Moreover by considering the full decay chain Omega ->Lambda K -> p pi K the magnitude of the asymmetry parameters beta Omega and gamma Omega can be obtained. This method, applied here to the specific Omega case, can be generalized to any weakly decaying hyperon and is perfectly suited for the PANDA experiment where hyperon-antihyperon pairs will be copiously produced in proton-antiproton collisions. The aim is to take a step forward towards the understanding of the mechanism that reigns strangeness production in these processes.

    Topics in Mean-Field Control and Games for Pure Jump Processes2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis is the collection of four papers addressing topics in stochastic optimal control, zero-sum games, backward stochastic differential equations, Pontryagin stochastic maximum principle and relaxed stochastic optimal control.

    In the first two papers, we establish existence of Markov chains of mean-field type, with countable state space and unbounded jump intensities. We further show existence of nearly-optimal controls and, using a Markov chain backward SDE approach, we derive conditions for existence of an optimal control and a saddle-point for a zero-sum differential game associated with risk-neutral and risk-sensitive payoff functionals of mean-field type, under dynamics driven by Markov chains of mean-field type. Our formulation of the control problems is of weak-type, where the dynamics are given in terms of a family of probability measures, under which the coordinate process is a pure jump process with controlled jump intensities.

    In the third paper, we characterize the optimal controls obtained in the first pa-per by deriving sufficient and necessary optimality conditions in terms of a stochastic maximum principle (SMP). Finally, within a completely different setup, in the fourth paper we establish existence of an optimal stochastic relaxed control for stochastic differential equations driven by a G-Brownian motion.

The aim of this qualitative study was to describe the perceptions and practices of breastfeeding among Somalian women living in Sweden after migration. Twenty-five Somalian immigrant women participated voluntarily. Data were collected from in-depth individual semi-structured interviews. The interviews took place in an adult school in Uppsala and homes in Uppsala and its surroundings. They were recorded and transcribed verbatim. Qualitative content analysis was used, and the Theory of Planned Behavior was the conceptual framework for the construction of categories and subcategories. Four categories emerged: (i) breastfeeding beneficial but doesn’t always work, (ii) effects of cultural and traditional beliefs, (iii) professional support by health care providers, and (vi) feeling stress after childbirth in the new country. The women perceived breastfeeding as positive, but several barriers led them to the combined use of formula and breastfeeding and the early introduction of supplementary food. Cultural, religious and traditional beliefs influenced their feeding practices. In conclusion, the women had not extensively changed their breastfeeding perceptions and practices due to the change of their environment; they mostly followed their cultural beliefs and traditions. Getting understanding of the women’s beliefs and practices is a first step for providing culturally informed health promotion. Antenatal care intervention programs for Somalis should involve the whole family and support breastfeeding by emphasizing its cultural and religious significance.

    Predictive Vehicle Motion Control for Post-Crash Scenarios2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents an active safety system for passenger vehicles designed to mitigate secondary collisions after an initial impact. Thecontrol objective is to minimize lateral deviation from the known original path while achieving a safe heading angle after the initialcollision. A hierarchical controller architecture is proposed: the higher layer is formulated as a linear time-varying model predictivecontroller that defines the virtual control moment input; the lower layer deploys a rule-based controller that realizes the requestedmoment. The designed control system is tested and validated on a high-fidelity vehicle dynamics simulator.

    Working alliance as a predictor of change in depression during blended cognitive behaviour therapy2018Inngår i: Cognitive Behaviour Therapy, ISSN 1650-6073, E-ISSN 1651-2316, s. 1-15Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Blended Cognitive Behaviour Therapy (bCBT) is a new form of treatment, mixing internet-based modules and face-to-face therapist sessions. How participants rate the therapeutic alliance in bCBT has not yet been thoroughly explored, and neither is it clear whether therapist- and patient-rated alliances are predictors of change in depression during treatment. Depression and alliance ratings from 73 participants in a treatment study on bCBT (part of the E-COMPARED project) were analysed using growth curve models. Alliance, as rated by both patients and therapists, was high. The therapist-rated working alliance was predictive of subsequent changes in depression scores during treatment, whereas the patient-rated alliance was not. A therapeutic alliance can be established in bCBT. The role of the therapist-rated alliance seems to be of particular importance and should be carefully considered when collecting data in future studies on bCBT.
