    • Mechanisms of antibiotic action shape the fitness landscapes of resistance mutations 

      Hemez, Colin; Clarelli, Fabrizio; Palmer, Adam C.; Bleis, Christina; Abel, Sören; Chindelevitch, Leonid; Cohen, Theodore; Abel zur Wiesch, Pia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-24)
      Antibiotic-resistant pathogens are a major public health threat. A deeper understanding of how an antibiotic’s mechanism of action influences the emergence of resistance would aid in the design of new drugs and help to preserve the effectiveness of existing ones. To this end, we developed a model that links bacterial population dynamics with antibiotic-target binding kinetics. Our approach allows ...

      Construction waste management is becoming an emerging issue in light of the massive increase in construction activities in the developing economies as part of their rapid economic growth. The gradual tightening of building regulations towards energy consumption creates the need to decrease the building materials and components during construction, and one of the proposed ways to achieve it is to ...
    • Age prediction by deep learning applied to Greenland halibut (Reinhardtius hippoglossoides) otolith images 

      Martinsen, Ivar; Harbitz, Alf; Bianchi, Filippo Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-04)
      Otoliths (ear-stones) in the inner ears of vertebrates containing visible year zones are used extensively to determine fish age. Analysis of otoliths is a time-consuming and difficult task that requires the education of human experts. Human age estimates are inconsistent, as several readings by the same human expert might result in different ages assigned to the same otolith, in addition to an ...

      Arctic ecosystems are changing dramatically with warmer and wetter conditions resulting in complex interactions between herbivores and their forage. We investigated how Svalbard reindeer (Rangifer tarandus platyrhynchus) modify their late winter diets in response to long-term trends and interannual variation in forage availability and accessibility. By reconstructing their diets and foraging ...
    • Why are Svalbard Arctic foxes Brucella spp. seronegative? 

      Nymo, Ingebjørg Helena; Fuglei, Eva; Mørk, Torill; Breines, Eva Marie; Holmgren, Karin Elisabeth; Davidson, Rebecca K.; Tryland, Morten (Journal article; Tidsskriftartikkel, 2022-07-06)
      Arctic foxes (Vulpes lagopus) are susceptible to smooth Brucella (s-Brucella) infection and may be exposed to such bacteria through the consumption of infected marine mammals, as implied by the finding of s-Brucella antibodies in polar bears (Ursus maritimus). Arctic foxes in Svalbard have not previously been investigated for s-Brucella antibodies, but such antibodies have been detected in Arctic ...
    • Novel long non-coding RNAs of relevance for ulcerative colitis pathogenesis 

      Ray, Mithlesh Kumar; Fenton, Christopher Graham; Paulssen, Ruth H (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-06)
      Background and aims: The study aimed to identify yet unknown and uncharacterized long non-coding RNAs (lncRNAs) in treatment-naïve ulcerative colitis (UC), and to define their possible roles in UC pathogenesis. For that purpose, accurate quantification methods for lncRNA transcript detection, multiple and “stringent” strategies were applied. New insights in the regulation of functional genes and ...

      Mæhre, Kjersti Sunde; Solstad, Elsa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-04)
      The encounter between divergent institutional logics may be challenging for nurses, since they must balance different expectations in their daily institutional work. These challenges increase when new reforms are introduced. Our research question is: How do actors linked to a palliative care unit experience the consequences of the Coordination reform in their daily performance of care work? Our ...
    • Phylogenetic position of the relict South American genus Idiopyrgus Pilsbry, 1911 (Gastropoda, Truncatelloidea), with the description of two new cave species 

      Salvador, Rodrigo Brincalepe; Silva, Fernanda Santos; Bichuette, Maria Elina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-14)
      Idiopyrgus is a relict genus of freshwater snails from Brazil traditionally classified in the family Pomatiopsidae. Herein, we use molecular data from newly acquired specimens to test that classification through Bayesian inference phylogenetic analysis. We conclude that Idiopyrgus belongs in the Gondwanan family Tomichiidae, together with the African genus Tomichia and the Australian genus Coxiella. ...
    • Towards a Jōmon food database: construction, analysis and implications for Hokkaido and the Ryukyu Islands, Japan 

      Komatsu, Aya; Cooper, Elisabeth; Alsos, Inger Greve; Brown, Antony (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-27)
      One of the most entrenched binary oppositions in archaeology and anthropology has been the agriculturalist vs hunter-gatherer-fisher dichotomy fuelling a debate that this paper tackles from the bottom-up by seeking to reconstruct full past diets. The Japanese prehistoric Jōmon cultures survived without fully-developed agriculture for more than 10,000 years. Here we compile a comprehensive, holistic ...
    • Review of 'Mixed categories: The morphosyntax of noun modification' 

      Fábregas, Antonio (Journal article; Tidsskriftartikkel, 2020-12-04)
      A scientific theory is judged by its ability to provide a principled explanation of less straightforward facts that lie at the margins of the data normally discussed and captured by other theories. To the extent that those data naturally follow from the new proposal, that theory is successfull in defining a new paradigm. Mixed Categories, by Irina Nikolaeva and Andrew Spencer, is an excellent example ...

      Aure, Marit; Førde, Anniken; Liabø, Rebekka (Journal article; Tidsskriftartikkel, 2020-04-02)
      Collaboration between researchers and artists is often held as particularly promising to enhance cross-cultural understanding. In this article, two researchers and an artist reflect on the potentials, as well as the pitfalls, of art-based interventions in integration of migrants. Through the performing arts youth project Here I Am, we discuss coproduction methodologies. We emphasize the discomfort ...
    • ShinyRBase: Near real-time energy saving models using reactive programming 

      Myrland, Øystein; Severinsen, Alexander (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)
      To document energy savings from retrofitting a building, a reliable baseline model is needed. The development and implementation of the baseline model is an important step in the measurement and verification (M&V) process. Usually, an energy analyst enters the stage, collects data, do the estimation and delivers the baseline model. The modeling work of the energy analyst is done on either a proprietary ...
    • iNaturalist as a tool in the study of tropical molluscs 

      Rosa, Rafael masson; Cavallari, Daniel caracanhas; Salvador, Rodrigo Brincalepe (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-05)
      Although terrestrial gastropods are remarkably diverse, our knowledge of them is still lacking, especially for species from the Global South. As such, new tools to help researchers collect data on these organisms are very welcome. With this in mind, we investigated Brazilian observations on iNaturalist to assess the feasibility of the data available on the platform as a basis for studies on the ...
    • General vs health-specific consideration of immediate and future consequences to predict eating and exercise behavior in a Norwegian student population: A randomized survey experiment 

      Pozolotina, Tatiana; Olsen, Svein Ottar (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-17)
      Over several decades, the consideration of future consequences (CFC) construct has been used to explain and predict health behaviors. However, the reported associations between CFC and health behaviors are relatively weak, leading to the low explanatory power of the models. Recent research suggests that CFC can be a domain-specific construct. In this study, we explored the psychometric properties ...
    • Ensemble Conformalized Quantile Regression for Probabilistic Time Series Forecasting 

      Jensen, Vilde; Bianchi, Filippo Maria; Anfinsen, Stian Normann (Journal article; Tidsskriftartikkel, 2022-11-04)
      This article presents a novel probabilistic forecasting method called ensemble conformalized quantile regression (EnCQR). EnCQR constructs distribution-free and approximately marginally valid prediction intervals (PIs), which are suitable for nonstationary and heteroscedastic time series data. EnCQR can be applied on top of a generic forecasting model, including deep learning architectures. EnCQR ...

      Grahn, Jakob; Bianchi, Filippo Maria (Journal article; Tidsskriftartikkel, 2022-09-06)
      In this article, we explore the possibility of detecting polar lows in C-band synthetic aperture radar (SAR) images by means of deep learning. Specifically, we introduce a novel dataset consisting of Sentinel-1 images divided into two classes, representing the presence and absence of a maritime mesocyclone, respectively. The dataset is constructed using the ECMWF reanalysis version 5 (ERA5) dataset ...
    • A clustering approach to heterogeneous change detection 

      Luppino, Luigi Tommaso; Anfinsen, Stian Normann; Moser, Gabriele; Jenssen, Robert; Bianchi, Filippo Maria; Serpico, Sebastian Bruno; Mercier, Gregoire (Chapter; Bokkapittel, 2017-05-19)
      Change detection in heterogeneous multitemporal satellite images is a challenging and still not much studied topic in remote sensing and earth observation. This paper focuses on comparison of image pairs covering the same geographical area and acquired by two different sensors, one optical radiometer and one synthetic aperture radar, at two different times. We propose a clustering-based technique ...
    • Resident bird species track inter-annual variation in spring phenology better than long-distance migrants in a subalpine habitat 

      Søraker, Jørgen Skavdal; Stokke, Bård Gunnar; Kleven, Oddmund; Moksnes, Arne; Rudolfsen, Geir; Skjærvø, Gine Roll; Vaagland, Henriette; Røskaft, Eivin; Ranke, Peter Sjolte (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-11)
      The ability to track variation in climate is important for species to persist in a given environment. Lack of responses to both long-term changes and inter-annual variation in climate parameters can result in reduced fitness and population decline. Furthermore, migration strategy can influence the ability to track climatic variation due to the potential to use reliable environmental cues. Here, ...
