    The mid‐ocean ridge system is the main source of earthquakes within the Arctic region. The earthquakes are recorded on the permanent land‐based stations in the region, although, smaller earthquakes remain undetected. In ...
  • Integrating Cognitive Learning Strategies into Physics Instruction : Developing students’ approaches to physics and learning 

    Gjerde, Vegard (Doctoral thesis, 2021-03-24)
    Introductory physics courses are obligatory for many disciplines outside of physics. As experienced by many students, they are notoriously difficult, often with high failure rates. Many students, whether they passed or ...
  • Mostar index and edge Mostar index of polymers 

    Ghanbari, Nima; Alikhani, Saeid (Journal article; Peer reviewed, 2021)
    Let G=(V,E) be a graph and e=uv∈E. Define nu(e,G) be the number of vertices of G closer to u than to v. The number nv(e,G) can be defined in an analogous way. The Mostar index of G is a new graph invariant defined as ...
  • Effect of different arachidonic acid levels in broodstock diet on egg quality of ballan wrasse (Labrus bergylta) 

    Sætre, Ruben Aldal (Master thesis, 2021-07-31)
    The production of ballan wrasse (Labrus bergylta) is growing and is becoming a focus area for the aquaculture industry. As a result of rising louse numbers and problems with resistance, biological methods such as cleaner ...
  • Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus) 

    Berg, Florian; Shirajee, Samina; Folkvord, Arild; Godiksen, Jane Aanestad; Skaret, Georg; Slotte, Aril (Journal article; Peer reviewed, 2021)
    Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ...
  • Teaching with digital geology in the high Arctic: opportunities and challenges 

    Senger, Kim; Betlem, Peter; Grundvåg, Sten-Andreas; Horota, Rafael Kenji; Buckley, Simon John; Smyrak-Sikora, Aleksandra; Jochmann, Malte Michel; Birchall, Thomas; Janocha, Julian; Ogata, Kei; Kuckero, Lilith; Johannessen, Rakul Maria; Lecomte, Isabelle Christine; Cohen, Sarah M.; Olaussen, Snorre (Journal article; Peer reviewed, 2021)
    The Covid-19 pandemic occurred at a time of major revolution in the geosciences – the era of digital geology. Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric ...
  • Semantics of multiway dataflow constraint systems 

    Haveraaen, Magne; Järvi, Jaakko (Journal article; Peer reviewed, 2021)
    Multiway dataflow constraint systems (MDCS) is a programming model where statements are not executed in a predetermined order. Rather, individual methods are selected from specific method sets and then executed to achieve ...
  • Specifying with syntactic theory functors 

    Haveraaen, Magne; Roggenbach, Marcus (Journal article; Peer reviewed, 2020)
    We propose a framework, syntactic theory functors (STFs), for creating syntactic structuring mechanisms for specification languages. Good support for common reuse patterns is important for systematically developing ...

  • Typical Sequences Revisited - Computing Width Parameters of Graphs 

    Bodlaender, Hans L.; Jaffke, Lars; Telle, Jan Arne (Journal article; Peer reviewed, 2021)
    In this work, we give a structural lemma on merges of typical sequences, a notion that was introduced in 1991 [Lagergren and Arnborg, Bodlaender and Kloks, both ICALP 1991] to obtain constructive linear time parameterized ...
  • Otolith “spawning zones” across multiple Atlantic cod populations: Do they accurately record maturity and spawning? 

    Denechaud, Côme; Geffen, Audrey J.; Smolinski, Szymon; Godiksen, Jane Aanestad (Journal article; Peer reviewed, 2021)
    Specific changes identified in the otolith macrostructure of Northeast Arctic cod as “spawning zones” are presumed to represent spawning events, but recent experimental studies have challenged this relationship. Because ...

    Tenningen, Maria; Zimmermann, Fabian; Enberg, Katja (Journal article; Peer reviewed, 2021)
    Unaccounted mortality caused by discarding or pre-catch losses is a major challenge for fisheries management. In pelagic fisheries, a considerable proportion of catches may be lost due to intentional release of unwanted ...

    The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and the lower part of the ionosphere and as such comprises a complex system coupled to both the atmosphere below and space above. The atmospheric ...
  • b-Coloring Parameterized by Clique-Width 

    Jaffke, Lars; Lima, Paloma Thome de; Lokshtanov, Daniel (Journal article; Peer reviewed, 2021)
    We provide a polynomial-time algorithm for b-Coloring on graphs of constant clique-width. This unifies and extends nearly all previously known polynomial-time results on graph classes, and answers open questions posed by ...
