    Subsurface fluxes of mass and energy at the accumulation zone of Lomonosovfonna ice cap, Svalbard2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Glaciers cover ca 10% of the Earth's land and are found in the high altitudes and latitudes. They are important components of environmental systems due to the multiple feedbacks linking them with the atmosphere, hydrosphere and periglacial landscapes. The cold sloping surfaces of glaciers change the patterns of atmospheric circulation at different scales and at the same time glaciers are largely controlled by climate. They are commonly used as climatic archives for reconstruction of the past environmental changes based on evidences from the areas affected by glaciation at the moment and in the past. Glaciers are the largest fresh-water reservoirs on our planet and runoff thereof significantly affects the global sea level and life in glaciated catchments. However, melt- and rain-induced runoff from glaciers greatly depends on the subsurface conditions which thus need to be taken into account, particularly in a changing climate.

    This thesis focuses on the processes of subsurface mass and energy exchange in the accumulation zones of glaciers, which are largely driven by the climate at the surface. Results are largely based on empirical data from Lomonosovfonna ice cap, Svalbard, collected during field campaigns in 2012-2017. Observations of subsurface density and stratigraphy using shallow cores, video records from boreholes and radar surveys returned detailed descriptions of the snow and firn layering. The subsurface temperature data collected using multiple thermistor strings provided insights into several subsurface processes. The temperature values measured during three summer seasons were used to constrain the suggested parameterization of deep preferential water flow through snow and firn. The part of data recorded during the cold seasons was employed for an inverse modelling exercise resulting in optimized values of effective thermal conductivity of the subsurface profile. These results are then used to compute the subsurface water content by comparing the simulated and measured rates of freezing front propagation after the melt season in 2014.

    The field observations and quantitative estimates provide further empirical evidences of preferential water flow in snow/firn packs at glaciers. Results presented in the thesis call for implementation of description of the process in layered models simulating the subsurface fluxes of energy and mass at glaciers. This will result in a better understanding of glacier response to the past and future climatic changes and more accurate estimates of glacier runoff.

    Development of a Smartphone App for a Genetics Website: The Amyotrophic Lateral Sclerosis Online Genetics Database (ALSoD)2013Inngår i: JMIR mhealth and uhealth, E-ISSN 2291-5222, Vol. 1, nr 2, e18Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The ALS Online Genetics Database (ALSoD) website holds mutation, geographical, and phenotype data on genes implicated in amyotrophic lateral sclerosis (ALS) and links to bioinformatics resources, publications, and tools for analysis. On average, there are 300 unique visits per day, suggesting a high demand from the research community. To enable wider access, we developed a mobile-friendly version of the website and a smartphone app. Objective: We sought to compare data traffic before and after implementation of a mobile version of the website to assess utility. Methods: We identified the most frequently viewed pages using Google Analytics and our in-house analytic monitoring. For these, we optimized the content layout of the screen, reduced image sizes, and summarized available information. We used the Microsoft. NET framework mobile detection property (HttpRequest. IsMobileDevice in the Request. Browser object in conjunction with HttpRequest. UserAgent), which returns a true value if the browser is a recognized mobile device. For app development, we used the Eclipse integrated development environment with Android plug-ins. We wrapped the mobile website version with the WebView object in Android. Simulators were downloaded to test and debug the applications. Results: The website automatically detects access from a mobile phone and redirects pages to fit the smaller screen. Because the amount of data stored on ALSoD is very large, the available information for display using smartphone access is deliberately restricted to improve usability. Visits to the website increased from 2231 to 2820, yielding a 26% increase from the pre-mobile to post-mobile period and an increase from 103 to 340 visits (230%) using mobile devices (including tablets). The smartphone app is currently available on BlackBerry and Android devices and will be available shortly on iOS as well. Conclusions: Further development of the ALSoD website has allowed access through smartphones and tablets, either through the website or directly through a mobile app, making genetic data stored on the database readily accessible to researchers and patients across multiple devices.

    Hospital comparison of stroke care in Sweden: a register-based study2017Inngår i: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 7, nr 9, e015244Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and purpose The objective of this study was to estimate the level of health outcomes and resource use at a hospital level during the first year after a stroke, and to identify any potential differences between hospitals after adjusting for patient characteristics (case mix). Method Data from several registries were linked on individual level: seven regional patient administrative systems, Swedish Stroke Register, Statistics Sweden, National Board of Health and Welfare and Swedish Social Insurance Agency. The study population consisted of 14 125 patients presenting with a stroke during 2010. Case-mix adjusted analysis of hospital differences was made on five aspects of health outcomes and resource use, 1 year post-stroke. Results The results indicated that 26% of patients had died within a year of their stroke. Among those who survived, almost 5% had a recurrent stroke and 40% were left with a disability. On average, the patients had 22 inpatient days and 23 outpatient visits, and 13% had moved into special housing. There were significant variations between hospitals in levels of health outcomes achieved and resources used after adjusting for case mix. Conclusion Differences in health outcomes and resource use between hospitals were substantial and not entirely explained by differences in patient mix, indicating tendencies of unequal stroke care in Sweden. Healthcare organisation of regions and other structural features could potentially explain parts of the differences identified.

    Effects of a culturally tailored parenting support programme in Somali-born parents' mental health and sense of competence in parenting: a randomised controlled trial2017Inngår i: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 7, nr 12, e017600Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: To evaluate the effectiveness of a culturally tailored parenting support programme on Somali-born parents' mental health and sense of competence in parenting.

    DESIGN: Randomised controlled trial.

    SETTING: A city in the middle of Sweden.

    PARTICIPANTS: Somali-born parents (n=120) with children aged 11-16 years and self-perceived stress in their parenting were randomised to an intervention group (n=60) or a waiting-list control group (n=60).

    INTERVENTION: Parents in the intervention group received culturally tailored societal information combined with the Connect parenting programme during 12 weeks for 1-2 hours per week. The intervention consisted of a standardised training programme delivered by nine group leaders of Somali background.

    OUTCOME: The General Health Questionnaire 12 was used to measure parents' mental health and the Parenting Sense of Competence scale to measure parent satisfaction and efficacy in the parent role. Analysis was conducted using intention-to-treat principles.

    RESULTS: The results indicated that parents in the intervention group showed significant improvement in mental health compared with the parents in the control group at a 2-month follow-up: B=3.62, 95% CI 2.01 to 5.18, p<0.001. Further, significant improvement was found for efficacy (B=-6.72, 95% CI -8.15 to -5.28, p<0.001) and satisfaction (B=-4.48, 95% CI -6.27 to -2.69, p<0.001) for parents in the intervention group. Parents' satisfaction mediated the intervention effect on parental mental health (β=-0.88, 95% CI -1.84 to -0.16, p=0.047).

    CONCLUSION: The culturally tailored parenting support programme led to improved mental health of Somali-born parents and their sense of competence in parenting 2 months after the intervention. The study underlines the importance of acknowledging immigrant parents' need for societal information in parent support programmes and the importance of delivering these programmes in a culturally sensitive manner.

    CLINICAL TRIAL REGISTRATION: NCT02114593.

    Experiences on Participation in Literary Activities: Intellectual Stimuli Empower People with Mental Health Problems2017Inngår i: Open Journal of Nursing, ISSN 2162-5336, E-ISSN 2162-5344, nr 7, 1307-1323 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Some research acknowledges engagement in creative and literary activities as constructively impacting rehabilitation and recovery. Nevertheless, there is a deficit of literature describing experiences of participation in literary activities. This study examined how members of a non-profit association for mental health, with experiences of mental problems or illnesses, experienced group-based literary activities facilitated of a bi-disciplinary research team during one semester. This study held a constructive/naturalistic design and used a qualitative methodology with a latent analysis to describe how participants experienced literary activities (creative writing, reading and conversations about published and own written poetry and prose texts). Both individual and focus-group interviews were performed early 2014. Despite previous negative experiences, the findings showed that the participants perceived the literary activities empowering. Four categories were created: Presumptions of personal literacy, leadership role, participants’ role, and literacy development. These were abstracted and interpreted into three themes: Identifying a reading and writing self-image, challenging and redefining one’s reading and writing identity, and strengthening one’s intellectual and humanistic capacity. Literary activities seemed to positively change the participants’ attitudes towards writing and reading, and also enhanced their literacy skills. We argue that literacy skills are interconnected with health literacy. Involvement of literary activities into rehabilitation in mental health practice may be beneficial for some groups, and merits further studies.

    Material properties of tapered crystalline silicon core fibers2017Inngår i: Optical Materials Express, ISSN 2159-3930, E-ISSN 2159-3930, Vol. 7, nr 6, 2055-2061 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Crystalline silicon optical fibers are emerging as a promising platform for a wide range of optoelectronic applications. Here we report a crystallographic study of the material properties within silicon fibers that have been post-processed via a tapering procedure to obtain small, few micron-sized core diameters. Our results reveal that the tapering process can improve the polysilicon quality of the core through the formation of large, centimeter long crystal grains, thus significantly reducing the optical losses.

    Use of Repeated Blood Pressure and Cholesterol Measurements to Improve Cardiovascular Disease Risk Prediction: An Individual-Participant-Data Meta-Analysis2017Inngår i: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 186, nr 8, 899-907 s.Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    The added value of incorporating information from repeated blood pressure and cholesterol measurements to predict cardiovascular disease (CVD) risk has not been rigorously assessed. We used data on 191,445 adults from the Emerging Risk Factors Collaboration (38 cohorts from 17 countries with data encompassing 1962-2014) with more than 1 million measurements of systolic blood pressure, total cholesterol, and high-density lipoprotein cholesterol. Over a median 12 years of follow-up, 21,170 CVD events occurred. Risk prediction models using cumulative mean values of repeated measurements and summary measures from longitudinal modeling of the repeated measurements were compared with models using measurements from a single time point. Risk discrimination (C-index) and net reclassification were calculated, and changes in C-indices were meta-analyzed across studies. Compared with the single-time-point model, the cumulative means and longitudinal models increased the C-index by 0.0040 (95% confidence interval (CI): 0.0023, 0.0057) and 0.0023 (95% CI: 0.0005, 0.0042), respectively. Reclassification was also improved in both models; compared with the single-time-point model, overall net reclassification improvements were 0.0369 (95% CI: 0.0303, 0.0436) for the cumulative-means model and 0.0177 (95% CI: 0.0110, 0.0243) for the longitudinal model. In conclusion, incorporating repeated measurements of blood pressure and cholesterol into CVD risk prediction models slightly improves risk prediction.

    FixK(2) Is the Main Transcriptional Activator of Bradyrhizobium diazoefficiens nosRZDYFLX Genes in Response to Low Oxygen2017Inngår i: Frontiers in Microbiology, ISSN 1664-302X, E-ISSN 1664-302X, Vol. 8, 1621Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The powerful greenhouse gas, nitrous oxide (N2O) has a strong potential to drive climate change. Soils are the major source of N2O and microbial nitrification and denitrification the main processes involved. The soybean endosymbiont Bradyrhizobium diazoefficiens is considered a model to study rhizobial denitrification, which depends on the napEDABC, nirK, norCBQD, and nosRZDYFLX genes. In this bacterium, the role of the regulatory cascade FixLJ-FixK(2)-NnrR in the expression of napEDABC, nirK, and norCBQD genes involved in N2O synthesis has been previously unraveled. However, much remains to be discovered regarding the regulation of the respiratory N2O reductase (N2OR), the key enzyme that mitigates N2O emissions. In this work, we have demonstrated that nosRZDYFLX genes constitute an operon which is transcribed from a major promoter located upstream of the nosR gene. Low oxygen was shown to be the main inducer of expression of nosRZDYFLX genes and N2OR activity, FixK(2) being the regulatory protein involved in such control. Further, by using an in vitro transcription assay with purified FixK(2) protein and B. diazoefficiens RNA polymerase we were able to show that the nosRZDYFLX genes are direct targets of FixK(2).

    Genetic variation in resistance of Norway spruce seedlings to damage by the pine weevil Hylobius abietis2017Inngår i: Tree Genetics & Genomes, ISSN 1614-2942, E-ISSN 1614-2950, Vol. 13, nr 5, 111Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Regeneration of northern conifer forests is commonly performed by reforestation with genetically improved materials obtained from long-term breeding programs focused on productivity and timber quality. Sanitary threats can, however, compromise the realization of the expected genetic gain. Including pest resistance traits in the breeding programs may contribute to a sustainable protection. Here we quantified the variation in different components of resistance of Norway spruce to its main pest, the pine weevil Hylobius abietis. We followed insect damage in two large progeny trials (52 open-pollinated families with 100-200 individuals per family and trial) naturally infested by the pine weevil. Pine weevils damaged between 17 and 48% of the planted seedlings depending on the trial and year, and mortality due to weevil damage was up to 11.4%. The results indicate significant genetic variation in resistance to the pine weevil, and importantly, the variation was highly consistent across trials irrespective of contrasting incidence levels. Individual heritability estimates for the different components of seedling resistance were consistently low, but family heritabilities were moderate (0.53 to 0.81). While forward selections and breeding for higher resistance seem not feasible, backwards selections of the best parent trees emerge as a putative alternative to reduce weevil damage. A positive genetic correlation between early growth potential and probability of being attacked by the weevil was also observed, but the relationship was weak and appeared only in one of the trials. Overall, results presented here open the door to a new attractive way for reducing damage caused by this harmful pest.

    The impacts of a Laki-like eruption on the present Swedish society2017Inngår i: Natural Hazards, ISSN 0921-030X, E-ISSN 1573-0840, Vol. 88, nr 3, 1565-1590 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study, we analyse and discuss the possible impacts on the Swedish society of a volcanic eruption on Iceland, emitting ash particles and large quantities of sulphur dioxide. A scenario was developed, based on the historical Laki eruption of 1783-1784, to describe the content of a potential sulphur fog over time in Sweden. Due to its high complexity and the many uncertainties in the underpinning scientific data, the scenario was developed using a cross-disciplinary approach incorporating experts from different scientific fields. An analysis of the impacts of the hazard on human health, environment and technical equipment was then performed and, finally, representatives from national authorities assessed the overall societal challenges in responding to the consequences of a massive volcanic eruption. The analysis shows that it is the peak concentrations of sulphur dioxide and sulphuric acid rather than the longer periods of moderate concentrations that contribute most to the negative consequences for human health and environment. Altogether, three societal challenges were identified: the ability to compile and disseminate relevant information fast enough, to perform continuous measurements of concentrations of different substances in affected areas and to meet the large demand for medical care.

    Parkinsonian symptoms in normal pressure hydrocephalus: a population-based study2017Inngår i: Journal of Neurology, ISSN 0340-5354, E-ISSN 1432-1459, Vol. 264, nr 10, 2141-2148 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It may be challenging to differentiate normal pressure hydrocephalus (NPH) from neurodegenerative disorders such as Parkinson's disease. In this population-based study, we wanted to describe the frequency of parkinsonian symptoms among individuals with and without NPH, and whether the motor examination part of the Unified Parkinson's Disease Rating Scale (UPDRS-m) score differs between these groups. Furthermore, we wanted to find out whether there was a relationship between UPDRS-m score, NPH symptoms, and radiological signs of NPH. A sample of 168 individuals over the age of 65 with and without self-reported symptoms of NPH underwent a computerized tomography of the brain and clinical examination, including UPDRS-m to grade parkinsonian symptoms. According to diagnostic guidelines, 38 fulfilled criteria for NPH, whereas 130 had unlikely NPH. Bradykinesia was significantly more common among those with NPH (79%) compared to those with unlikely NPH (32%) (p < 0.001). The corresponding figures for rigidity were 43 vs. 15% (p < 0.001), for postural instability 71 vs. 22% (p < 0.001), and for tremor at rest 5 vs. 6% (not significant). The total UPDRS-m score was significantly higher among individuals with NPH (median = 12) than without (median = 1) and correlated significantly with the degree of NPH symptoms (r = -0.72) and ventriculomegaly (r = 0.31). In this study, parkinsonian symptoms, except resting tremor, were frequent in individuals with NPH and correlated with the severity of NPH symptoms. Asymmetric symptoms were uncommon. We recommend a liberal use of neuroradiological imaging when investigating a patient with parkinsonian features.

    Object Instance Detection and Dynamics Modeling in a Long-Term Mobile Robot Context2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In the last years, simple service robots such as autonomous vacuum cleaners and lawn mowers have become commercially available and increasingly common. The next generation of service robots should perform more advanced tasks, such as to clean up objects. Robots then need to learn to robustly navigate, and manipulate, cluttered environments, such as an untidy living room. In this thesis, we focus on representations for tasks such as general cleaning and fetching of objects. We discuss requirements for these specific tasks, and argue that solving them would be generally useful, because of their object-centric nature. We rely on two fundamental insights in our approach to understand environments on a fine-grained level. First, many of today's robot map representations are limited to the spatial domain, and ignore that there is a time axis that constrains how much an environment may change during a given period. We argue that it is of critical importance to also consider the temporal domain. By studying the motion of individual objects, we can enable tasks such as general cleaning and object fetching. The second insight comes from that mobile robots are becoming more robust. They can therefore collect large amounts of data from those environments. With more data, unsupervised learning of models becomes feasible, allowing the robot to adapt to changes in the environment, and to scenarios that the designer could not foresee. We view these capabilities as vital for robots to become truly autonomous. The combination of unsupervised learning and dynamics modelling creates an interesting symbiosis: the dynamics vary between different environments and between the objects in one environment, and learning can capture these variations. A major difficulty when modeling environment dynamics is that the whole environment can not be observed at one time, since the robot is moving between different places. We demonstrate how this can be dealt with in a principled manner, by modeling several modes of object movement. We also demonstrate methods for detection and learning of objects and structures in the static parts of the maps. Using the complete system, we can represent and learn many aspects of the full environment. In real-world experiments, we demonstrate that our system can keep track of varied objects in large and highly dynamic environments.​

    The skin microbiome: impact of modern environments on skin ecology, barrier integrity, and systemic immune programming2017Inngår i: World Allergy Organization Journal, ISSN 1731-3317, E-ISSN 1939-4551, Vol. 10, 29Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Skin barrier structure and function is essential to human health. Hitherto unrecognized functions of epidermal keratinocytes show that the skin plays an important role in adapting whole-body physiology to changing environments, including the capacity to produce a wide variety of hormones, neurotransmitters and cytokine that can potentially influence whole-body states, and quite possibly, even emotions. Skin microbiota play an integral role in the maturation and homeostatic regulation of keratinocytes and host immune networks with systemic implications. As our primary interface with the external environment, the biodiversity of skin habitats is heavily influenced by the biodiversity of the ecosystems in which we reside. Thus, factors which alter the establishment and health of the skin microbiome have the potential to predispose to not only cutaneous disease, but also other inflammatory non-communicable diseases (NCDs). Indeed, disturbances of the stratum corneum have been noted in allergic diseases (eczema and food allergy), psoriasis, rosacea, acne vulgaris and with the skin aging process. The built environment, global biodiversity losses and declining nature relatedness are contributing to erosion of diversity at a micro-ecological level, including our own microbial habitats. This emphasises the importance of ecological perspectives in overcoming the factors that drive dysbiosis and the risk of inflammatory diseases across the life course.

    Effect of Environmental Regulation Stringency on the Pulp and Paper Industry2017Inngår i: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 9, nr 12, 2323Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    he article investigates whether environmental regulations have affected productivity development and technological change in the European pulp and paper industry. A dynamic panel data approach is selected for analyzing a sample consisting of the pulp and paper industries in eight European countries. Industry total factor productivity for the period 1993–2009 is used as the dependent variable; it is explained by the intensities of environmental regulations for various types of pollutants, as well as by a number of other independent variables. The econometric results indicate that the regulation of nitrogen oxides is associated with productivity improvements with a one-year lag, whereas regulations regarding sulphur dioxide and carbon dioxide have not had any statistically significant impact. In line with the a priori expectations, the price of pulp is connected to a negative effect, while lagged R&D expenditures have had corresponding positive impacts. However, since stationary tests are asymptotic and the data series are quite short, strong conclusions regarding the actual causal effect of environmental policy could not be drawn. The results could therefore not be viewed as a proof of the so-called strong Porter hypothesis postulating that stringent well-designed environmental regulations increase productivity growth compared to a no-policy scenario.

    Fast methods for electrostatic calculations in molecular dynamics simulations2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis deals with fast and efficient methods for electrostatic calculations with application in molecular dynamics simulations. The electrostatic calculations are often the most expensive part of MD simulations of charged particles. Therefore, fast and efficient algorithms are required to accelerate these calculations. In this thesis, two types of methods have been considered: FFT-based methods and fast multipole methods (FMM).

    The major part of this thesis deals with fast N.log(N) and spectrally accurate methods for accelerating the computation of pairwise interactions with arbitrary periodicity. These methods are based on the Ewald decomposition and have been previously introduced for triply and doubly periodic problems under the name of Spectral Ewald (SE) method. We extend the method for problems with singly periodic boundary conditions, in which one of three dimensions is periodic. By introducing an adaptive fast Fourier transform, we reduce the cost of upsampling in the non periodic directions and show that the total cost of computation is comparable with the triply periodic counterpart. Using an FFT-based technique for solving free-space harmonic problems, we are able to unify the treatment of zero and nonzero Fourier modes for the doubly and singly periodic problems. Applying the same technique, we extend the SE method for cases with free-space boundary conditions, i.e. without any periodicity.

    This thesis is also concerned with the fast multipole method (FMM) for electrostatic calculations. The FMM is very efficient for parallel processing but it introduces irregularities in the electrostatic potential and force, which can cause an energy drift in MD simulations. In this part of the thesis we introduce a regularized version of the FMM, useful for MD simulations, which approximately conserves energy over a long time period and even for low accuracy requirements. The method introduces a smooth transition over the boundary of boxes in the FMM tree and therefore it removes the discontinuity at the error level inherent in the FMM.

    Making Preciousness: Interaction Design Through Studio Crafts2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This dissertation explores value-creation in interaction design through practical collaborations with studio craftspersons. A focus is on the meaning of “preciousness” from a design perspective – what I refer to as Making Preciousness –  which highlights aspects of material properties, design processes, and the attitude to the design space. Theoretically, the work takes inspiration from the Japanese philosophy of Wabi-Sabi, which is based on the fact that things are impermanent, incomplete, and imperfect. This reflects a view of preciousness beyond notions of practical use, luxury or monetary cost. In addition to theoretical studies, I engaged in practice-based research at the intersection of interaction design and studio crafts, in the domains of leather, silversmith and textile crafting. Through an approach that blends these practices with the making of interactive artefacts, preciousness for interaction design was explored.

    Through this work, I extract three qualities, all of which are closely linked to attributes and values ​​embedded in the craft practices examined. I refer to these as resourceful composition, material sensuality and the aiming for mattering artefacts. Resourceful composition refers to approaching a design space “resourcefully”, meaning that the designer actively values and uses the specific qualities of materials and tools consciously, for what they are suitable for. Material sensuality is about appreciating the sensory experience of interacting with materials, arriving through particular material qualities, such as texture, temperature or smell, but also interactive qualities. Aiming for mattering artefacts involves actively designing for impermanence, incompleteness and imperfection, and through that contributing to notions of preciousness through use, care, ownership and interaction between users and artefacts over time.

    The attitude of making preciousness can be seen as tying together materials and making with user experiences of computational artefacts. For interaction design, this points towards making processes in which computation and material knowledge, craftsmanship and aesthetic intentions are placed at the core. These values ​​relate to cultural, but also sensual experiences, which can be seen as under-explored in the design of interactive products.

    Swarm Intelligence-Enhanced Detection of Non-Small-Cell Lung Cancer Using Tumor-Educated Platelets2017Inngår i: Cancer Cell, ISSN 1535-6108, E-ISSN 1878-3686, Vol. 32, nr 2, 238-252 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Blood-based liquid biopsies, including tumor-educated blood platelets (TEPs), have emerged as promising biomarker sources for non-invasive detection of cancer. Here we demonstrate that particle-swarm optimization (PSO)-enhanced algorithms enable efficient selection of RNA biomarker panels from platelet RNA sequencing libraries (n = 779). This resulted in accurate TEP-based detection of early- and late-stage non-small-cell lung cancer (n = 518 late-stage validation cohort, accuracy, 88%; AUC, 0.94; 95% CI, 0.92-0.96; p < 0.001; n = 106 early-stage validation cohort, accuracy, 81%; AUC, 0.89; 95% CI, 0.83-0.95; p < 0.001), independent of age of the individuals, smoking habits, whole-blood storage time, and various inflammatory conditions. PSO enabled selection of gene panels to diagnose cancer from TEPs, suggesting that swarm intelligence may also benefit the optimization of diagnostics readout of other liquid biopsy biosources.

    Abstract [sv]

    Denna artikel redovisar en enkätstudie utförd bland svenska tonåringar i åldern 17-18 år. Studien syftar till att kartlägga deras användning av fiktion i olika medieformer i kontexterna skola och fritid. Studien har en kvantitativ ansats och fokuserar på aspekterna medieringstyp, kön och studieinriktning. Resultaten visar att även om deltagarna läser skönlitteratur, tillbringar de mycket mer tid med fiktion i andra medieformer, såsom datorspel, tv-serier och film. Könsskillnader syns i att män spelar datorspel och kvinnor läser skönlitteratur i större utsträckning. Det finns få framträdande skillnader mellan elevgrupper med olika studieinriktning. Istället visar resultaten att skillnader i medieanvändning framför allt ska beaktas på individnivå, och att stora skillnader kan finnas inom samma skolklass. Resultaten diskuteras utifrån ett medieekologiskt och ett medialiseringsperspektiv i relation till utbildningssammanhang.

    Search for neutrinos from dark matter self-annihilations in the center of the Milky Way with 3 years of IceCube/DeepCore2017Inngår i: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 77, nr 9, 627Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present a search for a neutrino signal from dark matter self-annihilations in the Milky Way using the Ice-Cube Neutrino Observatory (IceCube). In 1005 days of data we found no significant excess of neutrinos over the background of neutrinos produced in atmospheric air showers from cosmic ray interactions. We derive upper limits on the velocity averaged product of the darkmatter self-annihilation cross section and the relative velocity of the dark matter particles <sigma Av >. Upper limits are set for darkmatter particle candidate masses ranging from 10GeV up to 1TeV while considering annihilation through multiple channels. This work sets the most stringent limit on a neutrino signal from dark matter with mass between 10 and 100GeV, with a limit of 1.18 . 10-23 cm(3)s(-1) for 100GeV dark matter particles self-annihilating via iota(+)iota(-) t-to neutrinos (assuming the Navarro-Frenk-White dark matter halo profile).

    Requirements on concrete floor structures - a comparison of medical imaging facilities2017Inngår i: Nordic Concrete Research Publications , 2017 / [ed] Marianne Tange Holst, 2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Requirements management in construction projects have a tendency towards production-driven processes and definition of technical solutions. The stakeholders are involved by being asked to comment on defined products which can have consequences on the performance of the end-product. This comparison describes three projects within the Stockholm County where the scope to build new medical imaging facilities with the same requirements on the concrete floor structure. The result shows that the same requirements have resulted in different solutions which could have an impact on the performance of the buildings. Further research regarding tools for systematic requirements management is needed to ensure performance and sustainability of new buildings.

    Latitude and lake size are important predictors of over-lake atmospheric stability2017Inngår i: Geophysical Research Letters, ISSN 0094-8276, E-ISSN 1944-8007, Vol. 44, nr 17, 8875-8883 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Turbulent fluxes across the air-water interface are integral to determining lake heat budgets, evaporation, and carbon emissions from lakes. The stability of the atmospheric boundary layer (ABL) influences the exchange of turbulent energy. We explore the differences in over-lake ABL stability using data from 39 globally distributed lakes. The frequency of unstable ABL conditions varied between lakes from 71 to 100% of the time, with average air temperatures typically several degrees below the average lake surface temperature. This difference increased with decreasing latitude, resulting in a more frequently unstable ABL and a more efficient energy transfer to and from the atmosphere, toward the tropics. In addition, during summer the frequency of unstable ABL conditions decreased with increasing lake surface area. The dependency of ABL stability on latitude and lake size has implications for heat loss and carbon fluxes from lakes, the hydrologic cycle, and climate change effects.

    Tumor antigen glycosaminoglycan modification regulates antibody-drug conjugate delivery and cytotoxicity2017Inngår i: OncoTarget, ISSN 1949-2553, E-ISSN 1949-2553, Vol. 8, nr 40, 66960-66974 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aggressive cancers are characterized by hypoxia, which is a key driver of tumor development and treatment resistance. Proteins specifically expressed in the hypoxic tumor microenvironment thus represent interesting candidates for targeted drug delivery strategies. Carbonic anhydrase (CAIX) has been identified as an attractive treatment target as it is highly hypoxia specific and expressed at the cell-surface to promote cancer cell aggressiveness. Here, we find that cancer cell internalization of CAIX is negatively regulated by post-translational modification with chondroitin or heparan sulfate glycosaminoglycan chains. We show that perturbed glycosaminoglycan modification results in increased CAIX endocytosis. We hypothesized that perturbation of CAIX glycosaminoglycan conjugation may provide opportunities for enhanced drug delivery to hypoxic tumor cells. In support of this concept, pharmacological inhibition of glycosaminoglycan biosynthesis with xylosides significantly potentiated the internalization and cytotoxic activity of an antibody-drug conjugate (ADC) targeted at CAIX. Moreover, cells expressing glycosaminoglycan-deficient CAIX were significantly more sensitive to ADC treatment as compared with cells expressing wild-type CAIX. We find that inhibition of CAIX endocytosis is associated with an increased localization of glycosaminoglycan-conjugated CAIX in membrane lipid raft domains stabilized by caveolin-1 clusters. The association of CAIX with caveolin-1 was partially attenuated by acidosis, i.e. another important feature of malignant tumors. Accordingly, we found increased internalization of CAIX at acidic conditions. These findings provide first evidence that intracellular drug delivery at pathophysiological conditions of malignant tumors can be attenuated by tumor antigen glycosaminoglycan modification, which is of conceptual importance in the future development of targeted cancer treatments.

    Prevalence of mind and body exercises (MBE) in relation to demographics, self-rated health, and purchases of prescribed psychotropic drugs and analgesics2017Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 9, e0184635Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study aims to identify any differences regarding gender, age, socioeconomic status (SES), self-rated health, perceived stress and the purchase of prescribed drugs among people who practice mind and body exercises (MBE) extensively compared to people who do not. Methods: The study includes 3,913 men and 4,803 women aged 20-72 who participated in the Swedish Longitudinal Occupational Survey of Health (SLOSH). The respondents were divided into three groups depending on frequency of MBE practice (never/seldom/often). Measures regarding MBE practice, health behaviors, self-rated health, and illnesses were drawn from the SLOSH questionnaire, while more objective measures of socioeconomic status and education were derived from registry data. In addition, data on purchases of prescription drugs for all respondents were included in the study. These data were obtained from the Swedish Prescribed Drug Register, which contains information about prescription drugs dispensed at Swedish pharmacies. Separate analyses were performed for mental MBE (mindfulness, meditation, relaxation techniques) and physical MBE (yoga, Tai Chi, Qi Gong), respectively. Results: A high intensity MBE practice is cross-sectionally related to poor self-assessed health (sleeping problems, pain, depressive symptoms, mental disorders), high levels of stress, and high levels of purchases of psychotropic drugs and analgesics. These cross-sectional relationships are generally stronger for mental MBE than for bodily-directed MBE. More women than men are practicing MBE on a regular basis, and physically active people participate to a greater extent in MBE compared with the physically inactive. Conclusion: Overall, the study shows that frequent participation in mind and body exercises is associated with high levels of purchases of psychotropic drugs and analgesics as well as with poor self-assessed health and high levels of stress. However, since this is a cross-sectional study, it is impossible to establish cause and effect, and to further investigate the associations found; longitudinal studies that can account for temporality between covariates and MBE use are needed.

    Nitrogen effects on the pelagic food web are modified by dissolved organic carbon2017Inngår i: Oecologia, ISSN 0029-8549, E-ISSN 1432-1939, Vol. 184, nr 4, 901-916 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Global environmental change has altered the nitrogen (N) cycle and enhanced terrestrial dissolved organic carbon (DOC) loadings to northern boreal lakes. However, it is still unclear how enhanced N availability affects pelagic food web efficiency (FWE) and crustacean zooplankton growth in N limited boreal lakes. Here, we performed in situ mesocosm experiments in six unproductive boreal Swedish lakes, paired across a DOC gradient, with one lake in each pair fertilized with N (2011: reference year; 2012, 2013: impact years). We assessed how zooplankton growth and FWE were affected by changes in pelagic energy mobilization (PEM), food chain length (phytoplankton versus bacterial production based food chain, i.e. PP:BP), and food quality (seston stoichiometry) in response to N fertilization. Although PP, PEM and PP:BP increased in low and medium DOC lakes after N fertilization, consumer growth and FWE were reduced, especially at low DOC-potentially due to reduced phytoplankton food quality [increased C: phosphorus (P); N:P]. At high DOC, N fertilization caused modest increases in PP and PEM, with marginal changes in PP:BP and phytoplankton food quality, which, combined, led to a slight increase in zooplankton growth and FWE. Consequently, at low DOC (<12 mg L-1), increased N availability lowers FWE due to mismatches in food quality demand and supply, whereas at high DOC this mismatch does not occur, and zooplankton production and FWE may increase. We conclude that the lake DOC level is critical for predicting the effects of enhanced inorganic N availability on pelagic productivity in boreal lakes.

    Abstract [en]

    This article asks why people are obsessed with Jane Austen’s stories and why her stories are spreading across the globe, across media forms, and across generations? In an attempt to analyse the Austenmania-phenomenon, this article examines various representations of Austen’s Sense and Sensibility in order to discuss what these representations contribute with to the understanding of the source text and to the text universe as a whole. The analysis shows that the re-presentations not only expand Austen’s story and provide insight into the characters and their actions, but also draw attention to historical and contemporary power hierarchies and gender roles.

    Abstract [en]

    The Swedish upper secondary school and its physical education (PE) should, according to the Lgy11 (the 2011 curriculum of upper secondary school in Sweden), raise aware- ness about and challenge stereotypes of masculinity and femininity. Previous research, however, has concluded that there is an upholding of traditional, hegemonic masculinity ideals through PE. The purpose of this article is to highlight how gender and power influence the outcome of a just education. Theoretical inspiration is taken from Irish Marion Young’s and Raewyn Connell’s work on gender and hegemonic masculinity, and the method involves interviews with PE teachers and observations of PE classes. Dance, ball games, competition, socializing violence, performance of heterosexual norms are identified as key points, which are discussed in terms of norms and power linked to men and masculinity ideals. The results show that the making of masculinity is constantly oc- curring in PE, both in active elements but also during “inactive” breaks. Although strong ideals linked to men and masculinity were identified, there were usually also alternative representations. In other words, the educational gender practices were not identified as unambiguous, but rather as ambiguous and contradictory. However, most respondents showed decided views on how boys and girls naturally “are” in certain ways, which con- ditions a counter-stereotypical approach to education.

    Representativity and Complementarity in Tai Chi as Embodied Documentation2017Inngår i: Proceedings from the Document Academy, ISSN 2473-215X, Vol. 4, nr 2, 1-24 s., 11Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this paper is to investigate what happens if we leave the criteria of materiality and permanence behind in the study of documents. How far can we stretch the definition of a document or define a documentation process in a situation where neither the originary fact, or object, nor that by which this is represented is material or permanent? Empirically, the paper is constructed as a case study of the traditional Chinese practice of Tai Chi and presents a formulation of the Tai Chi form as an immaterial document and Tai Chi pratice as a doumentation process. The article is structured as follows: (1) Tai Chi is characterised as both philosophy and practice and, (2) Tai Chi is discussed in relation to three conceptual ideas in Document Studies and Library and Information Science; (a) document representativity, (b) complementarity and (c) embodied information practice. Conclusions from the chosen perspectives suggest ”embodied documentation” as a conceptual tool with which to understand immaterial documents, something which may lead to a widened general understanding of documents and documentation processes.

    Managing Radio and Energy Resources in LTE-Based Military Training Networks2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The number of wireless connected devices are growing exponentially and the importance of this research area is growing as well to meet the known and looming challenges and expectations. The 5:th Generation telecommunications standard is partly embodied by the Machine-to-Machine (M2M) and Internet of Things (IoT) technologies and standards to handle a big part of these devices and connections. An example within the IoT paradigm is military training systems where each system can consist of thousands of battery operated mobile devices and their shifting requirements shall be fullled in an energy-aware manner to increase battery operating times.

    Military training radio networks enables realistic combat training. The services and features provided in commercial telecommunications networks are desirable in these often proprietary and task specic networks, increasing capabilities and functionalities. To facilitate the current and future R&D of LTE based networks for adoption in military training networks and services this doctoral thesis intends to provide the starting ground for the energy-aware LTE based wireless communications. The thesis first presents general solutions on how to meet traffic deadlines in wireless networks for large number of nodes, and then continues with solutions for energy-aware LTE-based communications for the User Equipments (UEs).

    The work builds on the problem formulation how to provide energy-aware resource handling for LTE-based military training networks from where three research questions are derived. From the research questions we derive different hypotheses and then test these within the investigated area to answer the research questions.

    The contributions of this work are within areas of resource handling and power saving for mobile devices. In the first area an admission control using deterministic analysis is proposed fullling traffic requirements for military training mobile nodes. This admission control is enhanced for multiple-channel base stations, and evaluated using mobile nodes with different heterogeneous traffic requirements. In the second part energy-awareness is in focus for LTE/LTE-A based networks. The main power saving method for LTE/LTE-A UEs, Discontinuous Reception (DRX) mechanism, is evaluated and models for DRX in Idle and Connected state are proposed including metrics for wake-up delay and power saving. Additionally a mean queuing delay analysis is proposed for a variant of the Connected state DRX. Using these models and metrics, practical design guidelines for tuning of DRX parameters are proposed, including optimization of DRX parameters for either minimizing delay or maximizing power saving.

    Expresiones de movimiento en español como segunda lengua y como lengua heredada: Conceptualización y entrega del Camino, la Manera y la Base2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The current thesis is based on four individual studies which aim to account for the expression of motion events (ME) in Spanish and Swedish as first languages (L1), in Swedish as a second language (L2), and in Spanish as a heritage language (SHL). The data, resulting from audio-recordings of different sorts of stimuli, have been analyzed with special focus on (1) the most common structures used for referring to various types of ME, (2) the types and amount of information provided by the participants, in particular as regards the semantic components Path, Manner and Ground, and (3) grammatical aspect and types of syntactic structures resorted to, including the correlation between the two latter factors and speakers’ discursive preferences.

         Study 1 sets out to explore how Spanish and Swedish native speakers convey information about motion. The results show that the Swedish L1 speakers produced a wider range of descriptions concerning Manner and Path than the Spanish L1 speakers; furthermore, both groups delivered detailed Ground descriptions, although the Swedish native speakers expressed final destinations (endpoints) of ME to a greater extent.

         Study 2 aims to investigate to what extent Swedish L1 patterns for motion encoding are still at play in the acquisition of Spanish L2 even at advanced stages of L2 acquisition. The results show that the learner group used a larger amount of Path particles and Ground adjuncts (in particular those referring to endpoints) than did the Spanish natives; this finding supports the claim that L2 learners rely on the lexicalization patterns of their L1 when describing ME in an L2. As for Manner, the L2 speakers were found to express this component mainly outside the verb, and to deliver more information about Manner than the Spanish natives.

         Study 3 addresses the construal of ME in Swedish speakers of L2 Spanish, in particular concerning the encoding of motion endpoints and Manner of motion. The results show that the Swedish learners of Spanish exhibited the same, high frequencies of endpoint marking as did their monolingual Swedish peers, thus deviating from the Spanish native pattern. Moreover, the L2 speakers used the same amount of Manner verbs as did the Spanish natives but tended consistently to provide additional Manner information in periphrastic constructions.

         Finally, Study 4 sets out to analyze the ways in which L1 Spanish/L2 Swedish early and late bilinguals express ME in SHL. The aim is to show in which ways and to what extent the typological patterns for motion encoding in the L2 may impact on motion encoding in the L1 with regard to three parameters: (1) age of onset (AO) of the acquisition of L2, (2) length of residence (LoR) in the L2 environment and (3) contact level with the L1 (CL). The focus data, consisting of oral re-tellings produced by the bilinguals, were compared to analogous data produced by two control groups (native speakers of Spanish and Swedish) in order to analyze conflation patterns regarding Manner, Path and Ground information. The analysis points to the conclusion that both the individuals’ AO of L2 acquisition and their LoR in the L2 environment have affected their L1 conceptualization patterns while their CL plays a subordinate role.

         In summary, the findings lend support to the idea that the habitual conceptualization of events in the L1 influences L2 acquisition; conversely, the conceptual patterns of the L2 have an impact on L1 usage in bilinguals, especially in combination with an early AO and a long LoR.

    Today, there is an essential need for lightweight, energy-efficient, environmentally benign engineering systems, and this is the driving force behind the development of a wide range of structural and functional materials for energy generation, energy storage, propulsion, and transportation. These challenges have motivated the use of magnesium alloys for lightweight structural systems. Magnesium has a density of 1.74 g/cm3, which is almost 30% less than that of aluminium, one quarter of steel, and almost identicalto polymers. The ease of recycling magnesium alloys as compared to polymers makes them environmentally attractive, but their poor mechanical performance is the primary reason for the limited adoption of these alloys for structural applications.

    The Mg-Al-Zn alloy AZ91D exhibits an excellent combination of strength, die-castability, and corrosion resistance. However, its mechanical performance with regard to creep strength, for example, at evaluated temperatures is poor. Moreover, very little is known about the correlation between its mechanical properties and microstructural features. This thesis aims to provide new knowledge regarding the role played by microstructure in the mechanical performance of the magnesium alloy. The properties/performance of the material in relation to process parameters became of great interest during the investigation.

    An exhaustive characterisation of the grain size, secondary dendrite arm spacing (SDAS) distribution, and fraction of Mg17Al12 was performed using optical and electron backscatter diffraction (EBSD). These microstructural parameters were correlated to the offset yield point (Rp0.2), fracture strength, and elongation to failure of the material. It was proposed that the intermetallic phase, Mg17Al12, plays an important role in determining the mechanical and physical properties of the alloy in a temperature range of room temperature to 190°C by forming a rigid network of intermetallic. The presence of this network was confirmed by studying the thermal expansion behaviour of samples of the alloy containing different amounts of Mg17Al12.

    A physically based constitutive model with a wide validity range was successfully adapted to describe the flow stress behaviour of AZ91D with various microstructures. The temperature-dependent variables of the model correlated quite well with the underlying physics of the material. The model was validated through comparison with dislocation densities obtained using EBSD.

    The influence of high-pressure die-cast parameters on the distortion and residual stress of the cast components was studied, as were distortion and residual stress in components after shot peening and painting. Interestingly, it was found that intensification pressure has a major effect on distortion and residual stresses, and that the temperature of the fixed half of the die had a slight influence on the component's distortion and residual stress.

    Singing the body electric: Understanding the role of embodiment in performing and composing interactive music2017Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Almost since the birth of electronic music, composers have been fascinated by the prospect of integrating the human voice with its expressiveness and complexity into electronic musical works. This thesis addresses how performing with responsive technologies in mixed works, i.e. works that combine an acoustic sound source with a digital one, is experienced by participating singers, adopting an approach of seamlessness, of zero – or invisible – interface, between singer and computer technology. It demonstrates how the practice of composing and the practice of singing both are embodied activities, where the many-layered situation in all its complexity is of great importance for a deepened understanding. The overall perspective put forward in this thesis is that of music as a sounding body to resonate with, where the resonance, a process of embodying, of feeling and emotion, guides the decision-making. The core of the investigation is the lived experiences through the process of composing and performing three musical works. One result emerging from this process is the suggested method of calibration, according to which a bodily rooted attention forms a kind of joint attention towards the work in the making. Experiences from these three musical works arrive in the formulation of an over-arching framework entailing a view of musical composition as a process of construction – and embodied mental simulation – of situations, whose dynamics unfold to engage musicians and audience through shifting fields of affordances, based on a shared landscape of affordances.

    Embodied aesthetic movements during mealtime: a provocative method for design innovation of culinary utensils2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In 2010, the project MER was funded be The Knowledge (KK) foundation. Lars Eriksson, associate professor in applied aestetics and creative events at Grythytte Academy Örebro University, initiated the project MER which focuses on the way people move and interact in the environment around the meal.

    This project has conducted a number of studies about the meeting between utensils, food and the guest in motion, creating the culinary experience. The poster presents a summary of a provocative method applied in all of the different studies.
