      Møller, Peter Daniel Rask; Schwarzhans, Werner W.; Lauridsen, Henrik; Nielsen, Jørgen G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-08)
      Two specimens from the Koko Seamount (Koko Guyot), in the Hawaiian-Emperor seamount chain, Central North Pacific, caught in 2009 and 2010 are here described as a new species, Bidenichthys okamotoi. The taxonomy of the species in the genera Bidenichthys Barnard, 1934, and Fiordichthys Paulin, 1995, has been confusing due to the lost type of B. consorbrinus (Hutton, 1876) and the rarity of some ...

    • Automating Historical Source Transcription 

      Thorvaldsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-31)
      Transcribing the 1950 Norwegian census with 3.3 million person records and linking it to the Central Population Register (CPR) provides longitudinal information about significant population groups during the understudied period of the mid-20th century. Since this source is closed to the public, we receive no help from genealogists and rather use machine learning techniques to semi-automate the ...

    • Spatially enriched paralog rearrangements argue functionally diverse ribosomes arise during cold acclimation in arabidopsis 

      Martinez-Seidel, Federico; Beine‐golovchuk, Olga; Hsieh, Yin-Chen; El Eshraky, Kheloud; Gorka, Michal; Cheong, Bo-Eng; Jimenez‐posada, Erika V.; Walther, Dirk; Skirycz, Aleksandra; Roessner, Ute; Kopka, Joachim; Pereira Firmino, Alexandre Augusto (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-07)
      Ribosome biogenesis is essential for plants to successfully acclimate to low temperature. Without dedicated steps supervising the 60S large subunits (LSUs) maturation in the cytosol, e.g., Rei-like (REIL) factors, plants fail to accumulate dry weight and fail to grow at suboptimal low temperatures. Around REIL, the final 60S cytosolic maturation steps include proofreading and assembly of functional ...

    • Influence of concrete’s mechanical properties on the cracking of concrete dams 

      Ulfberg, Adrian; Seger, Andreas; Bista, Dipen; Wilde, Marie Westberg; Johansson, Fredrik; Das, Oisik; Sas, Gabriel (Conference object; Konferansebidrag, 2021-09)
      Analytical methods of structural stability assessment of concrete dams are often too simple and thus conservative in their predictions.Without the actual foundation geometry, capacity for some rigid body failure modes are underestimated. This is problematic when deciding upon remediation activities of a dam that is considered unstable and may divert the restoration activities from where they are ...
