Environmental risk assessment of combined effects in aquatic ecotoxicology: A discussion paper
(Peer reviewed; Journal article, 2014)Environmental regulatory edicts within the EU, such as the regulatory framework for chemicals REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), the Water Framework Directive (WFD), and the Marine ... -
Lil3 dimerization and chlorophyll binding in Arabidopsis thaliana
(Peer reviewed; Journal article, 2015)The two-helix light harvesting like (Lil) protein Lil3 belongs to the family of chlorophyll binding light harvesting proteins of photosynthetic membranes. A function in tetrapyrrol synthesis and stabilization of geranylgeraniol ... -
EPW Cubes
(Journal article; Peer reviewed, 2016-08)We construct a new 20-dimensional family of projective six-dimensional irreducible holomorphic symplectic manifolds. The elements of this family are deformation equivalent with the Hilbert scheme of three points on a K3 ... -
Some factors affecting the grades of technology students
(Peer reviewed; Journal article, 2017)In this study factors that affect the grades of Norwegian technology students have been investigated. The total data set contained 355.706 individual exams from 63 different engineering master programs during the 2010 to ... -
Science AMA Series: Ask the Society of Environmental Toxicology and Chemistry (SETAC) anything about Pharmaceuticals in the environment!
(Journal article, 2017)The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... -
Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory
(Journal article; Peer reviewed, 2017-02)John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ... -
On a class of integrable systems of Monge-Ampère type
(Journal article; Peer reviewed, 2017-06)We investigate a class of multi-dimensional two-component systems of Monge-Ampère type that can be viewed as generalisations of heavenly type equations appearing in a self-dual Ricci-flat geometry. Based on the Jordan-Kronecker ... -
Universal spacetimes in four dimensions
(Journal article; Peer reviewed, 2017-10)Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ... -
Anomalous low-temperature thermodynamics of QCD in strong magnetic fields
(Journal article; Peer reviewed, 2017-11)The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ... -
Value regions of univalent self-maps with two boundary fixed points
(Journal article; Peer reviewed, 2018)In this paper we find the exact value region V(z0,T) of the point evaluation functional f → f(z0) over the class of all holomorphic injective self-maps f : D → D of the unit disk D having a boundary regular fixed point at ... -
Scattering amplitudes of massive Nambu-Goldstone bosons
(Journal article; Peer reviewed, 2018-01)Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ... -
Chiral density wave versus pion condensation at finite density and zero temperature
(Journal article; Peer reviewed, 2018-04)The quark-meson model is often used as a low-energy effective model for QCD to study the chiral transition at finite temperature T, baryon chemical potential μB, and isospin chemical potential μI. We determine the parameters ... -
Effect of additives, ball milling and isotopic exchange in porous magnesium borohydride
(Journal article; Peer reviewed, 2018-08)Magnesium borohydride (Mg(BH4)2) is a promising material for solid state hydrogen storage. However, the predicted reversible hydrogen sorption properties at moderate temperatures have not been reached due to sluggish ... -
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
(Journal article; Peer reviewed, 2018-10)We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study the phase diagram in the μI–T planewhere μI is the isospin chemical potential. In particular, we focus on the ... -
Nonperturbative analysis of the electroweak phase transition in the two Higgs doublet model
(Journal article; Peer reviewed, 2018-11)We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
