Hyper-Kähler fourfolds and Kummer surfaces
(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 ... -
Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
(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 ... -
Sensitivity analysis of a pathway with respect to fast and small temperature change
(Journal article; Peer reviewed, 2019)Temperature affects all enzymes simultaneously in a metabolic system. The enzyme concentration in a biochemical system can be considered as invariant under fast and small temperature change. Therefore, the total sensitivity ... -
Microwave-Assisted One-Pot Synthesis of Novel Polyarylpyrrole Derivatives of Expected Anticancer Activity
(Journal article, 2017)An efficient synthesis of Novel pyrrolederivatives was achieved via solventless reaction of chalcones 1(a-e) with different aldehydes 2(a-e) and ammonium acetate in the presence of sodium cyanide in one-pot under microwave ... -
Environmental harm assessment of a wastewater discharge from Hammerfest LNG: A study with biomarkers in mussels (Mytilus sp.) and Atlantic cod (Gadus morhua)
(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
(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 ... -
A new species of Pollenia Robineau-Desvoidy, 1830 from Jordan (Diptera: Calliphoridae: Polleniinae)
(Journal article; Peer reviewed, 2016-01)A new species, Pollenia bartaki sp. nov., assigned to the Pollenia rudis species-group in Pollenia Robineau-Desvoidy, 1830, is described on the basis of a single male specimen captured in Jordan. Its strongly curved surstylus ... -
Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields
(Journal article; Peer reviewed, 2017-06)We perform numerical simulations of Cold Electroweak Baryogenesis, including for the first time in the Bosonic sector the full electroweak gauge group SU(2) × U(1) and CP-violation. We find that the maximum generated baryon ... -
Simulations of "tunnelling of the 3rd kind"
(Journal article; Peer reviewed, 2017-07)We consider the phenomenon of “tunnelling of the 3rd kind” [1], whereby a magnetic field may traverse a classically impenetrable barrier by pair creation of unimpeded quantum fermions. These propagate through the barrier ... -
Dimensional reduction of the Standard Model coupled to a new singlet scalar field
(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 ... -
On high-order perturbative calculations at finite density
(Journal article; Peer reviewed, 2017-02)We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the determination of generic Feynman integrals ... -
Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time
(Journal article; Peer reviewed, 2017-07)We revisit the numerical computation of the baryon asymmetry from Cold Electroweak Baryogenesis given the physical Higgs mass. We investigate the dependence of the asymmetry on the speed at which electroweak symmetry ... -
Anomalous electrodynamics of neutral pion matter in strong magnetic fields
(Journal article; Peer reviewed, 2017-03)The ground state of quantum chromodynamics in sufficiently strong external magnetic fields and at moderate baryon chemical potential is a chiral soliton lattice (CSL) of neutral pions [1]. We investigate the interplay ... -
Chiral soliton lattice and charged pion condensation in strong magnetic fields
(Journal article; Peer reviewed, 2017-04)The Chiral Soliton Lattice (CSL) is a state with a periodic array of topological solitons that spontaneously breaks parity and translational symmetries. Such a state is known to appear in chiral magnets. We show that CSL ... -
Inhomogeneous chiral condensate in the quark-meson model

On-shell parameter fixing in the quark-meson model
(Journal article; Peer reviewed, 2017-02)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ... -
Variable setpoint as a relaxing component in physiological control
(Journal article; Peer reviewed, 2017-09)Setpoints in physiology have been a puzzle for decades, and especially the notion of fixed or variable setpoints have received much attention. In this paper, we show how previously presented homeostatic controller motifs, ... -

Primordial Gravitational Waves with LISA
(Journal article; Peer reviewed, 2017)Primordial Gravitational Waves are the next target of modern cosmology. They represent a window on the early Universe and the only probe of the physics and microphysics of the inflationary period. When the production of ... -
PLATINUM SENSITIVE 2 LIKE impacts growth, root morphology, seed set, and stress responses
(Journal article; Peer reviewed, 2017-07)Eukaryotic protein phosphatase 4 (PP4) is a PP2A-type protein phosphatase that is part of a conserved complex with regulatory factors PSY2 and PP4R2. Various lines of Arabidopsis thaliana with mutated PP4 subunit genes ...
