  • Killing superalgebras for Lorentzian four-manifolds 

    de Medeiros, Paul; Figueroa-O’Farrill, José; Santi, Andrea (Journal article; Peer reviewed, 2016-06)
    We determine the Killing superalgebras underpinning field theories with rigid unextended supersymmetry on Lorentzian four-manifolds by re-interpreting them as filtered deformations of Z-graded subalgebras with maximum odd ...

    Electroweak baryogenesis is a simple and attractive candidate mechanism for generating the observed baryon asymmetry in the Universe. Its viability is sometimes investigated in terms of an effective field theory of the ...
  • Submaximal conformal symmetry superalgebras for Lorentzian manifolds of low dimension 

    de Medeiros, Paul (Journal article; Peer reviewed, 2016-02)
    We consider a class of smooth oriented Lorentzian manifolds in dimensions three and four which admit a nowhere vanishing conformal Killing vector and a closed two-form that is invariant under the Lie algebra of conformal ...

    The light-harvesting-like (LIL) proteins are a family of membrane proteins that share a chlorophyll a/b-binding motif with the major light-harvesting antenna proteins of oxygenic photoautotrophs. LIL proteins have been ...
  • Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop 

    Andersen, Jens O.; Naylor, William R.; Tranberg, Anders (Journal article; Peer reviewed, 2014-04)
    We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magnetic background B at finite temperature T ...
  • Cold Baryogenesis from first principles in the two-Higgs doublet model with fermions 

    Mou, Zong-Gang; Saffin, Paul M.; Tranberg, Anders (Journal article; Peer reviewed, 2015-06)
    We present a first-principles numerical computation of the baryon asymmetry in electroweak-scale baryogenesis. For the scenario of Cold Baryogenesis, we consider a one fermion-family reduced CP-violating two Higgs-doublet ...
  • Inverse magnetic catalysis and regularization in the quark-meson model 

    Andersen, Jens O.; Naylor, William R.; Tranberg, Anders (Journal article; Peer reviewed, 2015-02)
    Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral ...
  • The use of Palladium on Magnetic Support as Catalyst for Suzuki-Miyaura Cross-Coupling Reactions 

    Sydnes, Magne Olav (Journal article; Peer reviewed, 2017-01-23)
    The development of new solid supports for palladium has received a lot of interest lately. These catalysts have been tested in a range of cross-coupling reactions, such as Suzuki–Miyaura, Mizoroki-Heck, and Sonogashira ...
  • The organization of controller motifs leading to robust plant iron homeostasis 

    Agafonov, Oleg; Selstø, Christina Helen; Thorsen, Kristian; Xiang, Ming Xu; Drengstig, Tormod; Ruoff, Peter (Journal article; Peer reviewed, 2016-01)
    Iron is an essential element needed by all organisms for growth and development. Because iron becomes toxic at higher concentrations iron is under homeostatic control. Plants face also the problem that iron in the soil is ...
  • Natural peptides with antioxidant activity from Atlantic cod and Atlantic salmon residual material 

    Pampanin, Daniela M.; Haar, Marianne Bore; Sydnes, Magne Olav (Journal article; Peer reviewed, 2016-03)
    Summary. Water-soluble peptides/proteins with molecular weight below 10 kDa were isolated from residual material of cod (liver, skin, and cod mix i.e. skin, frames, and viscera), and salmon (skin, and salmon mix i.e. skin, ...
  • Stem cell regulation: Implications when differentiated cells regulate symmetric stem cell division 

    Høyem, Marte Rørvik; Måløy, Frode; Jakobsen, Per; Brandsdal, Bjørn Olav (Journal article; Peer reviewed, 2015-05)
    We use a mathematical model to show that if symmetric stem cell division is regulated by differentiated cells, then changes in the population dynamics of the differentiated cells can lead to changes in the population ...
  • Epidemiology and classification of gastroenteropancreatic neuroendocrine neoplasms using current coding criteria 

    Sandvik, Oddvar Mathias; Søreide, Kjetil; Gudlaugsson, Einar; Kvaløy, Jan Terje; Søreide, Jon Arne (Journal article; Peer reviewed, 2015-09)
    Background: The lack of uniform criteria for coding of gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) has hampered previous epidemiological studies. The epidemiology of GEP-NEN was investigated in this study ...
  • Leptogenesis in crossing and runaway regimes. 

    Hohenegger, Andreas; Kartavtsev, Alexander (Journal article; Peer reviewed, 2014-07)
    We study the impact of effective thermal masses and widths on resonant leptogenesis. We identify two distinct possibilities which we refer to as ‘crossing’ and ‘runaway’ regimes. In the runaway regime the mass difference ...
  • Basis invariant measure of CP-violation and renormalization. 

    Hohenegger, Andreas; Kartavtsev, Alexander (Journal article; Peer reviewed, 2015-08)
    We analyze, in the context of a simple toy model, for which renormalization schemes the CP-properties of bare Lagrangian and its finite part coincide. We show that this is the case for the minimal subtraction and on-shell ...
  • Type III and II universal spacetimes 

    Hervik, Sigbjørn; Pravdova, Alena; Pravda, Vojtech (Journal article; Peer reviewed, 2015)
    We briefly summarize our recent results on universal spacetimes. We show that universal spacetimes are necessarily CSI, i.e. for these spacetimes, all curvature invariants constructed from the Riemann tensor and its ...

    Hervik, Sigbjørn; Pravda, V; Pravdova, A (Journal article; Peer reviewed, 2015)
    Universal spacetimes are vacuum solutions to all theories of gravity with the Lagrangian L [...]. Well known examples of universal spacetimes are plane waves which are of the Weyl type N. Here, we discuss recent results ...

    N-terminal acetylation (NTA) catalysed by N-terminal acetyltransferases (Nats) is among the most common protein modifications in eukaryotes, but its significance is still enigmatic. Here we characterize the plant NatA ...
  • Covariate order tests for covariate effect 

    Kvaløy, Jan Terje (Journal article; Peer reviewed, 2002)
    A new approach for constructing tests for association between a random right censored life time variable and a covariate is proposed. The basic idea is to first arrange the observations in increasing order of the covariate ...
