Pålhaugen, Lene; Sudre, Carole H; Teceläo, Sandra Raquel Ramos; Nakling, Arne; Almdahl, Ina Selseth; Kalheim, Lisa Flem; Cardoso, M Jorge; Johnsen, Stein Harald; Rongve, Arvid; Aarsland, Dag; Bjørnerud, Atle; Selnes, Per; Fladby, Tormod (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
White matter hyperintensities (WMHs) are associated with vascular risk and Alzheimer’s disease. In this study, we examined relations between WMH load and distribution, amyloid pathology and vascular risk in 339 controls ...
Computational modeling of ion concentration dynamics and metabolic oxygen consumption in brain tissue 
Sætra, Marte Julie (Doctoral thesis / Doktoravhandling, 2020)
Main research findings An increasing number of brain scientists resort to computers and mathematics as tools to unravel the brain. Instead of studying hands-on experiments alone, computational neuroscientists make use of ...

Predicting time to graduation at a large enrollment American university 
Aiken, John Mark; De Bin, Riccardo; Hjorth-Jensen, Morten; Caballero, Marcos Daniel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
The time it takes a student to graduate with a university degree is mitigated by a variety of factors such as their background, the academic performance at university, and their integration into the social communities of ...
Correlation between surface chemistry and morphology of PtCu and Pt nanoparticles during oxidation-reduction cycle 
Kalyva, Maria Evangelou; Sunding, Martin Fleissner; Gunnæs, Anette Eleonora; Diplas, Spyridon; Redekop, Evgeniy (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
Process conditions during catalytic reactions induce significant changes in surface chemistry and structure of bi- (mono) metallic nanoparticles leading to their deactivation, and this can ultimately affect the reactions ...
Nuclear Excitation Functions For Medical Isotope Production: Targeted Radionuclide Therapy via NatIr(d,x)193mPt 
Ekeberg, Hannah Lovise Okstad (Master thesis / Masteroppgave, 2020)
Determining Hydrogen's influence on electrically active defects in β - Ga2O3 
Verhoeven, Espen Førdestrøm (Master thesis / Masteroppgave, 2020)
On the Dynamics of the Autler-Townes effect 
Seputis, Arnoldas (Master thesis / Masteroppgave, 2020)
In this thesis the effect of Autler-Townes splitting is revisited and the dynamics of a 2- and 3-level quantum systems, exhibiting this effect, is studied. This effect is a special case of the Stark effect, where the ...
Bioimpedance Microelectrode Array on ASIC 
Drageseth, Magnus Flø (Master thesis / Masteroppgave, 2020)
Exploring Single Event Effects in the ALICE (A Large Ion Collider Experiment) SAMPA chip 
Mahmood, Sohail Musa (Doctoral thesis / Doktoravhandling, 2020)
After the second Long-Shutdown at the Large Hadron Collider, improved resolution requirements for the tracking detectors of the High Energy Physics experiments demand a higher number of readout channels and more compact ...
Experimental study of the pygmy dipole resonance in the (p,p'γ) reaction on 124Sn and its evolution in the Sn isotopic chain 
Markova, Maria (Master thesis / Masteroppgave, 2020)
The present thesis makes a specific focus on the experimental study of the pygmy dipole resonance (PDR) in $^{124}$Sn and its evolution with increasing number of neutrons for the $^{116-119,121,122}$Sn and $^{124}$Sn ...
