(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We review and extend a hierarchy of relaxation models for two-phase flow. The models are derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation source terms to drive it towards equilibrium. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Transition metal containing polyanion compounds are effective excellent electrode materials for sodium-ion batteries due to their high intrinsic electrochemical potentials and to the resulting high energy density. Iron ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Centrality, which quantifies the importance of individual nodes, is among the most essential concepts in modern network theory. As there are many ways in which a node can be important, many different centrality measures ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Magma intrusions grow to their final geometries by deforming the Earth's crust internally and by displacing the Earth's surface. Interpreting the related displacements in terms of intrusion geometry is key to forecasting ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We present an analytical solution based on the series expansion of Papkovich-Boussinesq's displacement potentials to derive the elastic solution of a spherical inclusion containing an eigenstrain or pressurized cavity in ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We investigate the migration mechanism of the carbon vacancy (VC) in silicon carbide (SiC) using a combination of theoretical and experimental methodologies. The VC, commonly present even in state-of-the-art epitaxial SiC ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The partial vibrational density of states (pVDOS) of ice Ih, as simulated by first principle modeling based on density functional theory (DFT), is utilized for computing the Cartesian components of the proton and oxygen ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)A selective sampling procedure is applied to reduce the number of density functional theory calculations needed to find energetically favorable grain boundary structures. The procedure is based on a machine learning algorithm ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)Two hybrid van der Waals density functionals (vdW-DFs) are developed using 25% Fock exchange with (i) the consistent-exchange vdW-DF-cx functional [K. Berland and P. Hyldgaard, Phys. Rev. B 89, 035412 (2014)] and (ii) with ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Importance The reproductive safety of benzodiazepine/z-hypnotic exposure on child longer-term developmental risks remains unresolved. Objective To quantify the association of motor, communication, and attention-defi ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Background: During pregnancy, many women experience sleep problems and anxiety that require treatment. The long-term safety for the child of maternal benzodiazepine (BZD) and z-hypnotic use during pregnancy remains ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We have constructed thin films of organic–inorganic hybrid character by combining titanium tetra-isopropoxide (TTIP) and the nucleobases thymine, uracil or adenine using the molecular layer deposition (MLD) approach. Such ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Zn substitutional lithium ( Li Zn ) and sodium ( Na Zn ) acceptors and their complexes with common donor impurities ( Al Zn , Hi, and HO) in ZnO have been studied using hybrid functional calculations. The results show ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Predictions of the anisotropic coefficients of thermal expansion are needed to not only compare to experimental measurement, but also as input for macroscopic modeling of devices which operate over a large temperature ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Using first principles calculations based on density functional theory, we study the impact of hole doping on the magnetic and electronic properties of two dimensional PtS2. Although 2D PtS2 is intrinsically non-magnetic, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)The nature of intrinsic defects in ZnO films grown by metal organic vapor phase epitaxy was studied by positron annihilation and photoluminescence spectroscopy techniques. The supply of Zn and O during the film synthesis ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Flavodoxins (Flds) are small, bacterial proteins that transfer electrons to various redox enzymes. Flavodoxins are reduced by ferredoxin/flavodoxin NADP+ oxidoreductases (FNRs), but little is known of the FNR-Fld interaction. ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)Last year, we reported a perturbative theory of the Casimir-Lifshitz torque between planar biaxially anisotropic materials in the retarded limit [Thiyam et al., Phys. Rev. Lett. 120, 131601 (2018)], which is applied here ...
