QCD at finite isospin density: chiral perturbation theory confronts lattice data
(Peer reviewed; Journal article, 2020)We consider the thermodynamics of three-flavor QCD in the pion-condensed phase at nonzero isospin chemical potential (μI) and vanishing temperature using chiral perturbation theory in the isospin limit. The transition from ... -
QCD phase diagram in a constant magnetic background: Inverse magnetic catalysis: where models meet the lattice
(Peer reviewed; Journal article, 2021)Magnetic catalysis is the enhancement of a condensate due to the presence of an external magnetic field. Magnetic catalysis at T=0 is a robust phenomenon in low-energy theories and models of QCD as well as in lattice ... -

Quantification and Qualitative Effects of Different PEGylations on Poly(butyl cyanoacrylate) Nanoparticles
(Journal article, 2017)Protein adsorption on nanoparticles (NPs) used in nanomedicine leads to opsonization and activation of the complement system in blood, which substantially reduces the blood circulation time of NPs. The most commonly used ... -
Quantification of Blood Flow in Cerebral Arteries at 7T MR
(Master thesis, 2022)Avbildning med 2D fasekontrast gjør det mulig å kvantifisere blodgjennomstrømning (mL/min) i cerebrale blodårer, og kan være et nyttig verktøy for å planlegge behandling og undersøke langtidseffekter hos pasienter med ... -
Quantifying the hydroxyapatite orientation near the ossification front in a piglet femoral condyle using X-ray diffraction tensor tomography
(Peer reviewed; Journal article, 2021)While a detailed knowledge of the hierarchical structure and morphology of the extracellular matrix is considered crucial for understanding the physiological and mechanical properties of bone and cartilage, the orientation ... -
Quantifying the influence of the stratosphere on the mesosphere and lower thermasphere
(Doctoral thesis at NTNU;2015:22, Doctoral thesis, 2015)In this thesis, the influence of the major modes of stratospheric variability - the seasonal cycle and sudden stratospheric warmings (SSWs) in the extratropics, and the quasi-biennial oscillation (QBO) in the equatorial ... -
Quantitative (S)TEM analysis of intermediate band solar cell materials
(Master thesis, 2011)In this thesis the strain properties of two InAs/GaAs quantum dot intermediate band solar cell materials have been explored. Both samples were thin films grown on a (100) GaAs substrate. The quantum dot material was InAs, ... -
Quantitative 3-D colocalization analysis as a tool to study the intracellular trafficking and dissociation of pDNA-chitosan polyplexes
(Journal article; Peer reviewed, 2012)Multichannel microscopy is frequently used to study intermolecular interactions and spatial relationships between biomolecules and organelles or vesicles in cells. Based on multichannel images, quantitative colocalization ... -
Quantitative 3D Imaging and Metrology Using Coherent X-ray Scattering
(Doctoral theses at NTNU;2017:300, Doctoral thesis, 2017)This thesis has focused on exploring methods of using coherent X-ray scattering at synchrotron sources. New imaging techniques using coherent X-ray scattering have been investigated, and it has been discussed how limitations ... -
Quantitative 3D X-ray Imaging of Densification, Delamination and Fracture in a Micro-Composite under Compression
(Journal article; Peer reviewed, 2015)Phase-contrast three-dimensional tomograms showing in unprecedented detail the mechanical response of a micro-composite subjected to a mechanical compression test are reported. The X-ray ptychography images reveal the ... -
Quantitative analysis of tumor heterogeneity based on magnetic resonance images
(Master thesis, 2019)Background: Solid tumors are commonly heterogeneous because they consist of cancer cells with different aggressiveness. In quantitative cancer imaging, such as magnetic resonance imaging (MRI), the heterogeneity will not ... -
Quantitative Analysis of Vascular Function in Malignant Tumours
(Master thesis, 2018)Sammendrag: Formålet med denne avhandlingen var å undersøke den vaskulære funksjonen i ondartede svulster ved hjelp av histologiske og immunohistokjemiske (IHC) snitt og se etter assosiasjoner med magnetresonanstomografi ... -
