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 ... -
A spacetime not characterized by its invariants is of aligned type II
(Journal article; Peer reviewed, 2011)By using invariant theory we show that a (higher-dimensional) Lorentzian metric that is not characterised by its invariants must be of aligned type II; i.e., there exists a frame such that all the curvature tensors ... -
All metrics have curvature tensors characterised by its invariants as a limit: the ϵ-property
(Journal article; Peer reviewed, 2011)We prove a generalisation of the ϵ-property, namely that for any dimension and signature, a metric which is not characterised by its polynomial scalar curvature invariants, there is a frame such that the components of the ... -
Alvamaja chlorometallica gen. n., sp. n. from Europe : the first metallic Rhinophoridae (Diptera)
(Journal article; Peer reviewed, 2010)Alvamaja chlorometallica gen. n., sp. n. is described from the southern part of Serbia. It has a perplexing combination of characters for an oestroid fly: green metallic body colour with silvery pollinosity; absence of ... -
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 ... -
Basis invariant measure of CP-violation and renormalization.
(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 ... -
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 ... -

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 ... -
Cold Baryogenesis from first principles in the two-Higgs doublet model with fermions
(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 ... -
Covariate order tests for covariate effect
(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
(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
(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
(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
(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
(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 ... -
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 ... -
Epidemiology and classification of gastroenteropancreatic neuroendocrine neoplasms using current coding criteria
(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
(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 ...
