      The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. ...
    • Bremsstrahlung as a probe of baryon stopping in heavy-ion collisions 

      Nese, Sigurd; Nystrand, Joakim Ingemar (Journal article; Peer reviewed, 2023)
      In collisions between heavy ions at ultra-relativistic energies the participating protons lose energy, which is converted into new particles. As the protons slow down, they emit bremsstrahlung radiation. The yield and ...
    • Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers 

      Sortland, Lene; Lennox, Robert; Velle, Gaute; Vollset, Knut; Kambestad, Marius (Journal article; Peer reviewed, 2023)
      1. The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human–predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate ...
    • How to find a good explanation for clustering? 

      Bandyapadhyay, Sayan; Fomin, Fedor; Golovach, Petr; Lochet, William Alexandre; Purohit, Nidhi; Simonov, Kirill (Journal article; Peer reviewed, 2023)
      k-means and k-median clustering are powerful unsupervised machine learning techniques. However, due to complicated dependencies on all the features, it is challenging to interpret the resulting cluster assignments. Moshkovitz, ...
    • The Connections Among Hamming Metric, b-Symbol Metric, and r-th Generalized Hamming Metric 

      Shi, Minjia; Zhu, Hongwei; Helleseth, Tor (Journal article; Peer reviewed, 2023)
      The r -th generalized Hamming metric and the b -symbol metric are two different generalizations of Hamming metric. The former is used on the wire-tap channel of Type II, and the latter is motivated by the limitations of ...
    • “Show me how to use a microscope” – The development and evaluation of certification as direct assessment of practical lab skills 

      Eidesen, Pernille Bronken; Bjune, Anne Elisabeth; Lang, Simone Iris (Journal article; Peer reviewed, 2023)
      Practical lab skills are rarely directly assessed. To improve constructive alignment between the described learning outcomes of practical skills and assessment, we developed and tested a certification procedure for microscopy ...
    • Classes of intersection digraphs with good algorithmic properties 

      Jaffke, Lars; Kwon, O-joung; Telle, Jan Arne (Journal article; Peer reviewed, 2023)
      While intersection graphs play a central role in the algorithmic analysis of hard problems on undirected graphs, the role of intersection digraphs in algorithms is much less understood. We present several contributions ...

    • Five-weight codes from three-valued correlation of M-sequences 

      Shi, Minjia; Qian, Liqin; Helleseth, Tor; Sole, Patrick (Journal article; Peer reviewed, 2023)
      In this paper, for each of six families of three-valued m-sequence correlation, we construct an infinite family of five-weight codes from trace codes over the ring R = F2 + uF2, where u2 = 0. The trace codes have the ...
    • The weight spectrum of two families of Reed-Muller codes 

      Carlet, Claude Michael; Solé, Patrick (Journal article; Peer reviewed, 2023)
      We determine the weight spectra of the Reed-Muller codes RM (m− 3, m) for m ≥ 6 and RM (m − 4, m) for m ≥ 8. The technique used is induction on m, using that the sum of two weights in RM (r −1, m−1) is a weight in RM (r, ...
    • Dynamic Programming on Bipartite Tree Decompositions 

      Jaffke, Lars; Morelle, Laure; Sau, Ignasi; Thilikos, Dimitrios M. (Journal article; Peer reviewed, 2023)
      We revisit a graph width parameter that we dub bipartite treewidth, along with its associated graph decomposition that we call bipartite tree decomposition. Bipartite treewidth can be seen as a common generalization of ...
    • Inverse Compton emission from heavy WIMP annihilations in the Galactic Centre 

      Djuvsland, Julia Isabell; Hinton, Jim; Reville, Brian (Journal article; Peer reviewed, 2023)
      A thermal relic WIMP remains a prime candidate for the nature of Dark Matter, particularly for the more poorly constrained case of a heavy ( 1 TeV) WIMP. The highest fluxes from WIMP annihilations are expected in the region ...
