(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background Main aim was assessment of regional blood–brain barrier (BBB) function by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in patients with neuroborreliosis. Secondary aim was to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Understanding plasma initiation in vacuum arc discharges can help to bridge the gap between nano-scale triggering phenomena and the macroscopic surface damage caused by vacuum arcs. We present a new two- dimensional ...
-
(Master thesis / Masteroppgave, 2011)FDG PET/CT scans from eleven patients with grade III or IV soft tissue sarcomas where obtained. Nine of the patients where liposarcomas, one was a schwannoma and one was a myxoid liposarcoma. Four of the patients were ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Cu2ZnSn(S,Se)4 is a promising nontoxic earth‐abundant solar cell absorber. To optimize the thin films for solar cell device performance, postdeposition treatments at temperatures below the crystallization temperature are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The potential and density wake behind a finite-sized object in a magnetized collisionless plasma flow is studied with self-consistent numerical simulations. With increasing magnetization of the plasma, the standard picture ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)This paper presents the derivation and experimental validation of algorithms for modeling and estimation of soft continuum manipulators using Lie group variational integration. Existing approaches are generally limited to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Purpose: To implement a dynamic contrast-based multi-echo MRI sequence in assessment of rectal cancer and evaluate associations between histopathologic data and the acquired dynamic contrast-enhanced (DCE) and dynamic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Throat aurora is defined as south-north aligned auroral arcs equatorward of the dayside cusp aurora and was suggested to be the results of cold magnetospheric plasma interaction with magnetopause reconnection, but its ...
-
(Master thesis / Masteroppgave, 2011)Software Defined Radio (SDR) and Cognitive Radio (CR) could be in all radio transmitters sometime in the future. This thesis gives information about both SDR and CR and how we could use these technologies to utilize the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The change in contact angles due to the injection of low salinity water or any other wettability altering agent in an oil-rich porous medium is modeled by a network of disordered pores transporting two immiscible fluids. ...

-
(Master thesis / Masteroppgave, 2018)During the winter season in the high arctic above Svalbard the sun is below the horizon not contributing to heating of the mesosphere and lower thermosphere (MLT) region (50-100 km). In this region there are no direct ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)Domain-walls in one-dimensional Ising ferromagnets can undergo Bloch oscillations when subjected to a skew magnetic field. Such oscillations imply finite temperature non-dispersive low-frequency peaks in the dynamical ...
-
(Master thesis / Masteroppgave, 2020)In this project we have studied the hydrodynamic forces that are acting on a small impurity submerged into a two-dimensional Bose-Einstein condensate at finite temperature. The condensate is modeled by the damped ...
-
(Master thesis / Masteroppgave, 2018)In this thesis the dynamics of a plasma blob in the scrape-off layer of a magnetic confinement device is investigated on the fundamental, kinetic level through particle simulations. New functionality is added to an existing ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We use high-speed photography to observe the dendritic freezing of ice between two closely spaced parallel plates. Measuring the propagation speeds of dendrites, we investigate whether there is a confinement-induced thermal ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Random networks of integrate-and-fire neurons with strong current-based synapses can, unlike previously believed, assume stable states of sustained asynchronous and irregular firing, even without external random background ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)A chain which is made to flow from a container, forms a striking arch that rises well above the container top. This phenomenon is caused by the well known Mould effect and is explained by a supply of momentum from the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Using the electron density (Ne) observations from the Defense Meteorological Satellite Program, and Constellation Observing Systems for Meteorology, Ionosphere, and Climate mission and simulations from the ...
-
(Master thesis / Masteroppgave, 2009)Stråleterapi er en vanlig behandlingsmetode av pasienter med kreft. Behandlingen utføres ved å bestråle områder i pasienten hvor det er kreftsykdom, og på den måten drepe kreftcellene. For at behandlingen skal være vellykket ...
