    • Glutamatergic modulation of auditory cortex connectivity with attentional brain networks in unpredictable perceptual environment 

      Kompus, Kristiina; Volehaugen, Vegard; Craven, Alexander R.; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-14)
      In a stable environment the brain can minimize processing required for sensory input by forming a predictive model of the surrounding world and suppressing neural response to predicted stimuli. Unpredicted stimuli lead to a prediction error signal propagation through the perceptual network, and resulting adjustment to the predictive model. The inter-regional plasticity which enables the model-building ...
    • Phosphorylation of steroid receptor coactivator-3 (SRC-3) at serine 857 is regulated by the p38 MAPK-MK2 axis and affects NF-κB-mediated transcription 

      Shrestha, Anup; Bruckmüller, Henrike; Kildalsen, Hanne; Kaur, Gurjit; Gaestel, Matthias; Ljones Wetting, Hilde; Mikkola, Ingvild; Seternes, Ole Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-09)
      Steroid receptor coactivator-3 (SRC-3) regulates the activity of both nuclear hormone receptors and a number of key transcription factors. It is implicated in the regulation of cell proliferation, inflammation and in the progression of several common cancers including breast, colorectal and lung tumors. Phosphorylation is an important regulatory event controlling the activities of SRC-3. Serine 857 ...

      Pal, Ratnabali; Sekh, Arif Ahmed; Kar, Samarjit; Prasad, Dilip K. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-16)
      The recent worldwide outbreak of the novel coronavirus (COVID-19) has opened up new challenges to the research community. Artificial intelligence (AI) driven methods can be useful to predict the parameters, risks, and effects of such an epidemic. Such predictions can be helpful to control and prevent the spread of such diseases. The main challenges of applying AI is the small volume of data and the ...

The empirical material in this longitudinal study includes interviews with three groups of teachers; from the project Matematikk i nord (2007–2011), ...
    • Soft thresholding schemes for multiple signal classification algorithm 

      Acuña Maldonado, Sebastian Andres; Opstad, Ida Sundvor; Godtliebsen, Fred; Ahluwalia, Balpreet Singh; Agarwal, Krishna (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-28)
      Multiple signal classification algorithm (MUSICAL) exploits temporal fluctuations in fluorescence intensity to perform super-resolution microscopy by computing the value of a super-resolving indicator function across a fine sample grid. A key step in the algorithm is the separation of the measurements into signal and noise subspaces, based on a single user-specified parameter called the threshold. ...
    • Deep Generative Models in Credit Scoring 

      Andrade Mancisidor, Rogelio (Doctoral thesis; Doktorgradsavhandling, 2021-02-05)
      Banks need to develop effective credit scoring models to better understand the relationship between customer information and the customer's ability to repay the loan. The output of such a model is called the default probability and is used to rank loan applications in terms of their creditworthiness. The focus of this thesis is to develop novel credit scoring methodologies that solve well-known ...

    • Iscenesatt ulikhet. Internasjonalt samarbeid i teaterutdanninger 

      Eriksen, Anne (Chapter; Bokkapittel, 2019-09-17)
      Denne artikkelen tar utgangspunkt i et samarbeidsprosjekt mellom teaterutdanningene ved et russisk og et norsk universitet og diskuterer hvordan ulikhet og uenighet om teatertradisjoner og undervisningsfilosofi kan brukes som en ressurs. I diskusjonen benyttes teori om demokrati og utdanning og teori om uenighetsfellesskap. Erfaringene oppsummeres med at trygge rammer, fleksibilitet og vektlegging ...
    • Drama og teater som tilnærming i aksjonsforskning - å øve på framtida. 

      Eriksen, Anne; Leming, Tove (Chapter; Bokkapittel, 2020-12-23)
      In this chapter, we ask how drama and theatre can be a useful approach to action research processes. We focus on interventions, using teacher education as an arena for development. The empirical point of view is based on several research and developmental projects over years, together with two examples from recent developmental work. Our theoretical framework is based on theories of learning and ...
    • Mangfoldsperspektiver i forskning på vold i nære relasjoner 

      Bredal, Anja; Eggebø, Helga; Eriksen, Astrid (Chapter; Bokkapittel, 2020-06-10)
      Most research on domestic violence has focused on violence against women in a gender perspective. However, there has been an increasing understanding of the importance of other social dimensions in order to understand the nature and impact of the violence. The aim of this chapter is to explore the current status of research on domestic violence in a diversity perspective. We argue that dimensions like ...

      Denby, Bruce; Gauss, Michael; Wind, Peter; Mu, Qing; Wærsted, Eivind Grøtting; Fagerli, Hilde; Valdebenito Bustamante, Alvaro Moises; Klein, Heiko (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-11)
      A description of the new air quality downscaling model – the urban EMEP (uEMEP) and its combination with the EMEP MSC-W model (European Monitoring and Evaluation Programme Meteorological Synthesising Centre West) – is presented. uEMEP is based on well-known Gaussian modelling principles. The uniqueness of the system is in its combination with the EMEP MSC-W model and the “local fraction” calculation ...

      Khezri, Abdolrahman; Avershina, Ekaterina; Ahmad, Rafi (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-27)
      Norway is known for being one of the countries with the lowest levels of antimicrobial resistance (AMR). AMR, through acquired genes located on transposons or conjugative plasmids, is the horizontal transmission of genes required for a given bacteria to withstand antibiotics. In this work, bioinformatic analysis of whole-genome sequences and hybrid assembled data from Escherichia coli, and Klebsiella ...

    • Unequivocal structure confirmation of a breitfussin analog by anisotropic NMR measurements 

      Ndukwe, Ikenna E.; Lam, Yu-hong; Pandey, Sunil Kumar; Haug, Bengt Erik; Bayer, Annette; Sherer, Edward C.; Blinov, Kirill A.; Williamson, R. Thomas; Isaksson, Johan; Reibarkh, Mikhail; Liu, Yizhou; Martin, Gary E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-21)
      Structural features of proton-deficient heteroaromatic natural products, such as the breitfussins, can severely complicate their characterization by NMR spectroscopy. For the breitfussins in particular, the constitution of the five-membered oxazole central ring cannot be unequivocally established via conventional NMR methods when the 4′-position is halogenated. The level of difficulty is exacerbated ...
    • Genetic interaction between the non‐homologous end joining factors during B and T lymphocyte development: in vivo mouse models 

      Castaneda Zegarra, Sergio Miguel; Fernandez Berrocal, Marion Silvana; Tkachev, Max; Yao, Rouan; Esnardo Upfold, Nikki Lyn; Oksenych, Valentyn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-12)
      Non‐homologous end joining (NHEJ) is the main DNA repair mechanism for the repair of double‐strand breaks (DSBs) throughout the course of the cell cycle. DSBs are generated in developing B and T lymphocytes during V(D)J recombination to increase the repertoire of B and T cell receptors. DSBs are also generated during the class switch recombination (CSR) process in mature B lymphocytes, providing ...
