During an EISCAT (European Incoherent Scatter Scientific Association) HF heating experiment, a GLONASS satellite signal intersected the disturbed ionospheric volume along the local magnetic field lines. The satellite ...
    • Small shrubs with large importance? Smaller deer may increase the moose-forestry conflict through feeding competition over Vaccinium shrubs in the field layer 

      Spitzer, Robert; Coissac, Eric; Felton, Annika M.; Fohringer, Christian; Juvany, Laura; Landman, Marietjie; Singh, Navinder J.; Taberlet, Pierre Robert Michel; Widemo, Fredrik; Cromsigt, Joris P. G. M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-18)
      The moose (Alces alces) is a dominant large mammalian herbivore in the world’s boreal zones. Moose exert significant browsing impacts on forest vegetation and are therefore often at the centre of wildlife-forestry conflicts. Consequently, understanding the drivers of their foraging behaviour is crucial for mitigating such conflicts. Management of moose in large parts of its range currently largely ...

    • Buried in between: Re-interpreting the Skjoldehamn Medieval Bog Burial of Arctic Norway 

      Svestad, Asgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-17)
      THE 11TH-CENTURY SKJOLDEHAMN GRAVE is a remarkable accidental find, discovered in a bog in coastal Arctic Norway in 1936. The grave consisted of a fully clothed skeleton wrapped in a wool blanket, lashed with leather straps and tin ring-ornamented woven bands. The body was laid on a reindeer pelt, which in turn was placed on sticks of birch. Finally, the body was covered with birch bark, and potentially ...
    • An Efficient Method for Computing Expected Value of Sample Information for Survival Data from an Ongoing Trial 

      Vervaart, Mathyn Adrianus Marinus; Strong, Mark; Claxton, Karl; Welton, Nicky; Wisløff, Torbjørn; Aas, Eline (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-30)
      Background - Decisions about new health technologies are increasingly being made while trials are still in an early stage, which may result in substantial uncertainty around key decision drivers such as estimates of life expectancy and time to disease progression. Additional data collection can reduce uncertainty, and its value can be quantified by computing the expected value of sample information ...
    • Variation in Genetic Mechanisms for Plumage Polymorphism in Skuas (Stercorarius) 

      Janssen, Kirstin; Bustnes, Jan Ove; Mundy, Nicholas I (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
      Coloration is evolutionarily labile and so provides an excellent trait for examining the repeatability of evolution. Here, we investigate the repeatability of the evolution of polymorphic variation in ventral plumage coloration in skuas (Stercorarius: Stercorariidae). In 2 species, arctic (S. parasiticus) and pomarine skuas (S. pomarinus), plumage polymorphism was previously shown to be ...

    • The state as a whiteman, the whiteman as a |'hun: Personhood, recognition, and the politics of knowability in the Kalahari 

      Ninkova, Velina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-24)
      The Ju|’hoansi of east central Namibia sometimes refer to the state as a whiteman and to the whiteman as a /’hun (steenbok). In this article, I contextualize these naming practices by tracing the history of colonial encounters on the fringes of the Western Kalahari through a small-scale animist perspective. I then discuss what this means for the concept of ‘recognition’, which I treat as a two-way ...

      Autophagy is a core molecular pathway for the preservation of cellular and organismal homeostasis. Pharmacological and genetic interventions impairing autophagy responses promote or aggravate disease in a plethora of experimental models. Consistently, mutations in autophagy-related processes cause severe human pathologies. Here, we review and discuss preclinical data linking autophagy dysfunction ...
    • Predicting Second Language Proficiency with Resting-State Brain Rhythms. 

      Ogunniyi, Victoria; Abugaber, David; Finestrat, Irene; Luque, Alicia; Morgan-Short, Kara (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-24)
      Understanding what traits facilitate second language (L2) learning has been the focus of many psycholinguistic studies for the last thirty years. One source of insight comes from quantitative electroencephalography (qEEG), i.e., electrical brain activity recorded from the scalp. Using qEEG, Prat et al. [1] found that functional brain connectivity is predictive of language learning ability. This study ...
