    • An Energy Balance Model on an Infinite Line 

      Elvevold, Ask (Master thesis; Mastergradsoppgave, 2022-06-01)
      The thesis is an expansion of the work Gerald R. North did in 1975 on an energy balance climate model. By considering a similar model on an infinite line, and allowing the heat diffusion coefficient to vary on the line, more complicated behaviour arose from the model. Much of Norths work was recreated on the infinite lines, but a lot of new discoveries were made. Among what was found were spontaneous ...

    • The role of avalanche education in assessing and judging avalanche risk factors 

      Landrø, Markus; Engeset, Rune Verpe; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-07)
      Avalanche decision-making falls into two general categories; probabilistic approaches and analytical approaches. Analytical approaches have traditionally been considered applicable to experts only, as they require assessing risk factors precisely and understanding their relevance in each situation. In this study we question this assumption. We asked 1,220 amateur backcountry recreationalists how ...

    • Cingulate cortex morphology impacts on neurofunctional activity and behavioral performance in interference tasks 

      Fedeli, Davide; Del Maschio, Nicola; Del Mauro, Gianpaolo; Defendenti, Federica; Sulpizio, Simone; Abutalebi, Jubin (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-11)
      Inhibitory control is the capacity to withhold or suppress a thought or action intentionally. The anterior Midcingulate Cortex (aMCC) participates in response inhibition, a proxy measure of inhibitory control. Recent research suggests that response inhibition is modulated by individual variability in the aMCC sulcal morphology. However, no study has investigated if this phenomenon is associated with ...

In the frame of the isolation campaign, it was investigated how different sample treatments, isolation ...
    • Explainability in subgraphs-enhanced Graph Neural Networks 

      Guerra, Michele; Bianchi, Filippo Maria; Scardapane, Simone; Spinelli, Indro (Journal article; Tidsskriftartikkel, 2023)
      Recently, subgraphs-enhanced Graph Neural Networks (SGNNs) have been introduced to enhance the expressive power of Graph Neural Networks (GNNs), which was proved to be not higher than the 1-dimensional Weisfeiler-Leman isomorphism test. The new paradigm suggests using subgraphs extracted from the input graph to improve the model’s expressiveness, but the additional complexity exacerbates an ...

    • Quartz rheology constrained from constant-load experiments: Consequences for the strength of the continental crust 

      Ghosh, Subhajit; Stunitz, Holger; Raimbourg, Hugues; Précigout, Jacques (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-21)
      The mechanical properties of quartz are fundamental to control the plastic behaviour of the continental crust. Our understanding of quartz rheology is still limited in the following respects: i) the large variability of flow law parameters in the earlier literature (stress exponent n = 4 to ≤ 2 and activation energy Q = 120 to 242 kJ/mol), and ii) the difficulty to identify the rate-limiting deformation ...

    • Hunting for Hide. Investigating an Other-Than-Food Relationship Between Stone Age Hunters and Wild Animals in Northern Europe 

      Skandfer, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-18)
      In archaeological hunter-gatherer research, animals are primarily seen as food. Alternatively, they are proposed to serve as symbols and devices for social structuring of human societies. A growing body of literature in humanities and social sciences now looks into the role of animals as social and sentient co-beings. It is becoming increasingly clear that the roles of animals as other-than-food ...
