      Villela, Darine; Che, Huiwen; Van Ghelue, Marijke; Dehaspe, Luc; Brison, Nathalie; Van Den Bogaert, Kris; Devriendt, Koen; Lewi, Liesbeth; Bayindir, Baran; Vermeesch, Joris Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-04)
      Non-invasive prenatal testing (NIPT) is accurate for fetal sex determination in singleton pregnancies, but its accuracy is not well established in twin pregnancies. Here, we present an accurate sex prediction model to discriminate fetal sex in both dichorionic diamniotic (DCDA) and monochorionic diamniotic/monochorionic monoamniotic (MCDA/MCMA) twin pregnancies. A retrospective analysis was performed ...
    • Warming trends and long-range dependent climate variability since year 1900: A Bayesian approach 

      Myrvoll-Nilsen, Eirik; Fredriksen, Hege-Beate; Sørbye, Sigrunn Holbek; Rypdal, Martin wibe (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-21)
      Temporal persistence in unforced climate variability makes detection of trends in surface temperature difficult. Part of the challenge is methodological since standard techniques assume a separation of time scales between trend and noise. In this work we present a novel Bayesian approach to trend detection under the assumption of long-range dependent natural variability, and we use estimates of ...

Each branch of the tree separates one single class from all other remaining classes, using a class-specific selected feature ...
    • Uwe Krüger: Warum wir den Medien nicht mehr trauen 

      Pötzsch, Holger (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-11)
      <i>Mainstream: Warum wir den Medien nicht mehr trauen</i> viser hvorfor en voksende avstand mellom borgere og elitene er problematisk for et demokratisk samfunn. En journalistikk som viser seg ute av stand til å kritisk følge elitedrevne prosesser og praksiser mister den sentrale vaktbikkjefunksjonen som man ofte uten videre ettertanke tildeler store medieaktører. <i>Krügers bok</i> kan sees som et ...
