    • 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 ...

    • Constraints on Strong Phase Transitions in Neutron Stars 

      Gorda, T.; Hebeler, K.; Kurkela, Eero Aleksi; Schwenk, A.; Vuorinen, A. (Peer reviewed; Journal article, 2023)
      We study current bounds on strong first-order phase transitions (PTs) along the equation of state (EOS) of dense strongly interacting matter in neutron stars, under the simplifying assumption that on either side of the PT, ...

    • 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 ...

    • Curvature operators and scalar curvature invariants 

      Hervik, Sigbjørn; Coley, Alan (Journal article; Peer reviewed, 2010)
      We continue the study of the question of when a pseudo-Riemannain manifold can be locally characterised by its scalar polynomial curvature invariants (constructed from the Riemann tensor and its covariant deriva- tives). ...

    • Dimensional reduction of the Standard Model coupled to a new singlet scalar field 

      Brauner, Tomas; Tenkanen, Tuomas; Tranberg, Anders; Vuorinen, Aleksi; Weir, David James (Journal article; Peer reviewed, 2017)
      We derive an effective dimensionally reduced theory for the Standard Model augmented by a real singlet scalar. We treat the singlet as a superheavy field and integrate it out, leaving an effective theory involving only the ...

    • Discriminating the Weyl type in higher dimensions using scalar curvature invariants 

      Hervik, Sigbjørn; Coley, Alan (Journal article; Peer reviewed, 2011)
      We consider higher dimensional Lorentzian spacetimes which are currently of interest in theoretical physics. It is possible to algebraically classify any tensor in a Lorentzian spacetime of arbitrary dimensions using ...

    • Downregulation of N-terminal acetylation triggers ABA-mediated drought responses in Arabidopsis 

      Linster, Eric; Stephan, Iwona; Bienvenut, Willy V.; Maple-Grødem, Jodi; Myklebust, Line Merethe; Huber, Monika; Reichelt, Michael; Sticht, Carsten; Møller, Simon Geir; Meinnel, Thierry; Arnesen, Thomas; Giglione, Carmela; Hell, Rüdiger; Wirtz, Markus (Journal article; Peer reviewed, 2015-07)
      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 ...

    • Effective field theory and electroweak baryogenesis in the singlet-extended Standard Model 

      Damgaard, P.H.; Haarr, A.; O'Connell, D.; Tranberg, Anders (Journal article; Peer reviewed, 2016-02)
      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 ...

    • Enantioselective synthesis of (-)-(1R,2R)-1,2-dihydrochrysene-1,2-diol 

      Lorentzen, Marianne; Sydnes, Magne Olav; Jørgensen, Kåre Bredeli (Peer reviewed; Journal article, 2014)
      A general chiral building block containing the 1R,2R-trans-diol moiety was constructed utilizing the stereoselective Shi-epoxidation reaction on a tetralone scaffold assembled by a Negishi cross-coupling on N,N-diethylbenzamide. ...

    • Environmental harm assessment of a wastewater discharge from Hammerfest LNG: A study with biomarkers in mussels (Mytilus sp.) and Atlantic cod (Gadus morhua) 

      Beyer, Jonny; Aarab, Nadia; Tandberg, Anne Helene Solberg; Ingvarsdottir, Anna; Bamber, Shaw Duncan; Børseth, Jan Fredrik; Camus, Lionel; Velvin, Roger (Journal article; Peer reviewed, 2013-04)
      Biologically treated wastewater (WW) from the Hammerfest LNG (liquefied natural gas) plant is discharged to the sea. A study using biomarkers in mussels and Atlantic cod was performed to examine whether this discharge meets ...

    • Environmental impacts of produced water and drilling waste discharges from the Norwegian offshore petroleum industry 

      Bakke, Torgeir Heggelund; Klungsøyr, Jarle; Sanni, Steinar (Journal article; Peer reviewed, 2013-09)
      Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research on the biological ...

    • 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 ...

    • Experimental and computational studies of turbulent mass transfer in a mixing channel 

      Hjertager, Bjorn H.; Osenbroch, Lene K. Hjertager; Solberg, Tron (Journal article; Peer reviewed, 2008)
      Experiments are carried out for passive mixing in order to obtain local mean and turbulent velocities and concentrations. The mixing takes place in a square channel with two inlets separated by a block. A combined PIV/PLIF ...

    • Higher dimensional bivectors and classification of the Weyl operator 

      Hervik, Sigbjørn; Coley, Alan (Journal article; Peer reviewed, 2010)
      We develop the bivector formalism in higher dimensional Lorentzian spacetimes. We define the Weyl bivector operator in a manner consis- tent with its boost-weight decomposition. We then algebraically classify the Weyl ...

      Ranestad, Kristian; Kapustka, Michal; Kapustka, Grzegorz; Iliev, Atanas (Journal article; Peer reviewed, 2017-09)
      We show that a Hilbert scheme of conics on a Fano fourfold double cover of PP2xP2 ramified along a divisor of bidegree (2,2) admits a ℙ 1‐fibration with base being a hyper‐Kähler fourfold. We investigate the geometry of ...
