(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The W and Z boson production was measured via the muonic decay channel in proton-lead collisions at sNN−−−√=5.02 TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward (−4.46 < y cms ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)This paper presents a simulation study of the wake formation behind a Langmuir probe thinner than the Debye Length in the space environments such as the ionosphere’s F region. We find that the wakes formed in plasma density ...

Wake Potential and Wake Effects on the Ionospheric Plasma Density Measurements With Sounding Rockets (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A new method is developed to systematically study variations in the electrostatic potential around a spinning spacecraft in flowing plasma. We argue that the main modulation of this potential is due to wake leading to ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)The electric potential distribution around a dust particle immersed in a magnetised supersonic plasma flow is studied by numerical simulations. It is shown that with increasing magnetisation of plasma, the peak in the wake ...
-
(Master thesis / Masteroppgave, 2014)In this thesis we have studied the structure and transport properties of water trapped in nanoporous fractures in silica. The studies are performed using a numerical method called molecular dynamics, using an advanced, ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)Pharmaceutical formulations intended for treatment of xerostomia (dry mouth) should be able to keep the oral mucosa hydrated for a prolonged period of time. The products already existing on the market contain water-soluble ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)In this study, polyol-made CdS and CdSe crystalline nanoparticles (NPs) are loaded by impregnation on TiO2 nanotube arrays (TNTAs) for solar-simulated light-driven photoelectrochemical (PEC) water vapor splitting. For the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Single-mode equivalent space-time representations of the acoustic wave propagating in a Biot poroelastic medium have previously been found only for asymptotic cases: In the low frequency regime, where the viscous skin depth ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Two popular theories for wave propagation in sediments, the Biot poroelastic theory and the Viscous Grain Shearing (VGS) theory, have been formulated in terms of dispersion relations. The lack of explicit wave equations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)This paper describes the theory for performing retrieval of radio occultations that use probing frequencies in the XK and KM band. Normally, radio occultations use frequencies in the L band, and GPS satellites are used as ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Ion sound waves are studied in a plasma subject to gravitational field giving rise to vertically inhomogeneous steady-state plasma conditions. Such systems are interesting by exhibiting a wave growth that is a result of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Computed Tomography (CT) images have a high dynamic range, which makes visualization challenging. Histogram equalization methods either use spatially invariant weights or limited kernel size due to the complexity of pairwise ...
-
(Master thesis / Masteroppgave, 2016)The aim of this work is to investigate if size and morphology of nanoparticles can be controlled by changing the hydrophilic ratio of the amphiphilic polymers, changing polymer concentration or simply by changing the ...

(Journal article / Tidsskriftartikkel / SubmittedVersion, 2021)What does it mean to “make sense” of physics? It’s not a simple question. Most people have an intuitive feeling for when things do (or do not) make sense to them. But putting this feeling into words—especially actionable ...

What Is Light? Students’ Reflections on the Wave-Particle Duality of Light and the Nature of Physics (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Quantum physics describes light as having both particle and wave properties; however, there is no consensus about how to interpret this duality on an ontological level. This article explores how pre-university physics ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Two sequences, before and after magnetic noon, respectively, of poleward moving auroral forms with associated upflows situated above the European Incoherent Scatter Svalbard Radar allowed close study of ion upflow dynamics. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Objective We used diffusion tensor imaging (DTI) to test the following hypotheses: (1) there is decreased white matter (WM) integrity in non-demented Parkinson’s disease (PD), (2) WM integrity is differentially reduced in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Evolution of hot and dense nuclear matter produced in central Au+Au collisions at energies of NICA, FAIR, and SPS is studied within two transport models. Two interesting features in the matter behaviour are observed almost ...
