    • Who's at risk in the backcountry? Effects of individual characteristics on hypothetical terrain choices 

      Mannberg, Andrea; Hendrikx, Jordy; Landrø, Markus; Ahrland Stefan, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-18)
      We use data from an online survey in Norway (N = 467, 73% male; age: M = 34, SD = 10.07) to analyze hypothetical choices in hazardous avalanche terrain. We further analyze differences in stated preference for and willingness to accept to ski relatively risky terrain. Our results suggest that risk attitudes and perception constitute important determinants for hypothetical terrain choices. We further ...
    • Border Performances: Politics, art and tourism where Norway meets Russia 

      Fors, Bjarge Schwenke (Doctoral thesis; Doktorgradsavhandling, 2019-02-25)
      This thesis deals with political, artistic and touristic performances on Norway’s border with Russia. Based on ethnographic research in and around the town of Kirkenes, the thesis demonstrates how the state border and the borderland are staged through these performances. On a more general level, it aims to identify, explore and increase our knowledge about the role of performances in the construction ...
    • Curvature Continuous Path Generation for UAVs based on Generalized Expo-Rational B-Splines 

      Andersen, Tom Stian; Bouzidi, Ghada; Kristiansen, Raymond (Peer reviewed; Book; Chapter, 2018)
      This paper proposes a new path-planning algorithm based on GERBS to generate curvature continuous paths. The algorithm blends between a set of local curves generating a global smooth path which also interpolates the midpoint of the curves. Numerical examples are provided which demonstrates the potential of the proposed algorithm.
    • Dual-quaternion backstepping control for a fully-actuated rigid-body 

      Andersen, Tom Stian; Johansen, Tor-Aleksander; Kristiansen, Raymond (Peer reviewed; Book; Chapter, 2018-08-16)
      In this paper dual-quaternions are used to model a fully actuated rigid-body. A backstepping-controller that solves the trajectory tracking problem is derived and proved to provide uniform asymptotical stabilization of the error dynamics. Numerical simulations are provided where the controller is compared to existing dual-quaternion tracking controllers and it is shown to have similar performance.

We used data from the Norwegian Women and Cancer Study and the Northern Sweden Health and Disease Study. Information ...
    • Human long intrinsically disordered protein regions are frequent targets of positive selection 

      Afanasyeva, Arina; Bockwoldt, Mathias; Cooney, Christopher; Heiland, Ines; Gossmann, Toni Ingolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-01)
      Intrinsically disordered regions occur frequently in proteins and are characterized by a lack of a well-defined three-dimensional structure. Although these regions do not show a higher order of structural organization, they are known to be functionally important. Disordered regions are rapidly evolving, largely attributed to relaxed purifying selection and an increased role of genetic drift. It has ...

    • Cognitive function and mild cognitive impairment in a general population: roles of cardiovascular and genetic risk factors and magnetic resonance volumetry. The Tromsø Study 

      Rogne, Sigbjørn Olav (Doctoral thesis; Doktorgradsavhandling, 2018-12-14)
      Alzheimers sykdom er den vanligste årsaken til demens, dernest karsykdom som forårsaker vaskulær demens. De fleste som får Alzheimers demens etter 65 års alder (late onset Alzheimer’s Disease, LOAD), har ikke sykdommen i familien fra tidligere. Men opptil 25 % av dem som får LOAD, har biologiske slektninger med LOAD. Personer i familier med opphopning av LOAD, har økt risiko for å få LOAD. Det er ...
    • Estimating treatment prolongation for persistent infections 

      Martinecz, Antal; Abel zur Wiesch, Pia (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-09)
      Treatment of infectious diseases is often long and requires patients to take drugs even after they have seemingly recovered. This is because of a phenomenon called persistence, which allows small fractions of the bacterial population to survive treatment despite being genetically susceptible. The surviving subpopulation is often below detection limit and therefore is empirically inaccessible but can ...
    • En Empirisk Studie av Autisme på Film og TV 

      Nordahl-Hansen, Anders; Tøndevold, Magnus; Øien, Roald A; Fletcher-Watson, Sue (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-02)
      There has been a rise of character portrayals of persons with Autism or autistic traits in TV and film. In this quantitative study we analyse 26 films and TV-shows with characters with Autistic traits and how these relate to diagnostic criteria in DSM-5. Out of all 26 portrayals, 20 showed at least 10 of all 12 symptom items. Our main findings indicate that portrayals, although aligning closely to ...
    • Hsa-miR-376c-3p targets cyclin D1 and induces G1-cell cycle arrest in neuroblastoma cells 

      Bhavsar, Swapnil Parashram; Løkke, Cecilie; Flægstad, Trond; Einvik, Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-11)
      High‑risk neuroblastoma is the most aggressive form of cancer in children. The estimated survival of children with high‑risk neuroblastoma is 40‑50% compared with low and intermediate risk neuroblastoma, which is >98 and 90‑95%, respectively. In addition, patients with high‑risk neuroblastoma often experience relapse following intensive treatments with standard chemotherapeutic drugs. Therefore ...

      <i><p>Background</i>: The immune response during P. falciparum infection is a two-edged sword, involving dysregulation of the inflammatory responses with several types of immune cells participating. Here we examined T-cell, monocyte/macrophage and neutrophil activation during P. falciparum infection by using soluble activation markers for these leukocyte subsets.</p> <i><p>Methods</i>: In a ...
    • Dissecting deep neural networks for better medical image classification and classification understanding 

      Hicks, Steven Alexander; Riegler, Michael; Pogorelov, Konstantin; Ånonsen, Kim Vidar; de Lange, Thomas; Johansen, Dag; Jeppsson, Mattis; Randel, Kristin Ranheim; Eskeland, Sigrun Losada; Halvorsen, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-23)
      Neural networks, in the context of deep learning, show much promise in becoming an important tool with the purpose assisting medical doctors in disease detection during patient examinations. However, the current state of deep learning is something of a "black box", making it very difficult to understand what internal processes lead to a given result. This is not only true for non-technical users but ...
