Exploring the diagnostic potential of adding T2 dependence in diffusion-weighted MR imaging of the prostate
(Peer reviewed; Journal article, 2021)Background: Magnetic resonance imaging (MRI) is essential in the detection and staging of prostate cancer. However, improved tools to distinguish between low-risk and high-risk cancer are needed in order to select the ... -
Exploring the Intersection of Brain–Computer Interfaces and Quantum Sensing: A Review of Research Progress and Future Trends
(Peer reviewed; Journal article, 2023)Brain–computer interfaces (BCIs) can revolutionize how humans interact with technology, but several scientific and technological challenges must be addressed to realize their full potential. Recent developments in quantum-based ... -
Exploring the Randall-Sundrum Universe
(Master thesis, 2014)In this thesis, we will explore the physics of warped extra dimensions. More specifically, we will concentrate on the model set forward by Lisa Randall and Raman Sundrum in their paper, "A Large Mass Hierarchy from a Small ... -
Expression of two Cell Membrane Proteins, CD37 and PD-L1, in Acute Myeloid Leukemia Cell Lines
(Master thesis, 2016)The standard chemotherapy treatment given to newly diagnosed Acute Myeloid Leukemia ( AML ) patients have remained practi- cally the same for the last forty years, and is poorly tolerated by the older patients. Several new ... -
External Gluons in QCD Scattering Amplitudes
(Master thesis, 2021)Manifest Lorentz-kovarians krever at man legger til langsgående polarisasjons- vektorer i summen over polariseringer for justerbosoner. Det resulterende kovariante utrykket brukes også som teller i Feynman-t' Hooft ... -
Extra electron diffraction spots caused by fine precipitates formed at the early stage of aging in Al-Mg-X (X=Si, Ge, Zn)-Cu alloys
(Journal article; Peer reviewed, 2017)Age-hardenable Al-Mg-Si, Al-Mg-Ge, and Al-Zn-Mg alloys including Cu were investigated by transmission electron microscopy to understand extra diffraction spots that appear in their selected area electron diffraction patterns. ... -
Extracellular vesicles in patients in the acute phase of psychosis and after clinical improvement: an explorative study
(Peer reviewed; Journal article, 2020)Extracellular vesicles (EVs) are cell-derived structures that transport proteins, lipids and nucleic acids between cells, thereby affecting the phenotype of the recipient cell. As the content of EVs reflects the status of ... -
Extracting OH airglow intensity from the background of the Nordic Optical Telescope
(Master thesis, 2019)Nattehimmellys fra OH-radikalet i mellomatmosfæren er en sterk kilde til nær infrarød stråling. Til tross for at strålingen er en besværlig og uunngåelig kilde til bakgrunnsstøy i bakkebasert nær infrarød astronomi, kan ... -
Extracting room geometry from impulse response measurements
(Master thesis, 2014)An algorithm for establishing room parameters from measured impulse responses is created and implemented in matlab. The script is defined for synthetic and measured impulse responses. The setup is optional placement of a ... -
Extragalactic Cosmic Rays
(Peer reviewed; Journal article, 2022)I review the status of ultrahigh-energy cosmic ray (UHECR) physics. After introducing the main experimental results and summarizing possible intepretations, I discuss observational and theoretical constraints on the sources ... -
Extreme enhancement of superconductivity in epitaxial aluminum near the monolayer limit
(Peer reviewed; Journal article, 2023)BCS theory has been widely successful at describing elemental bulk superconductors. Yet, as the length scales of such superconductors approach the atomic limit, dimensionality as well as the environment of the superconductor ... -
Fabrication and Characterisation of Porous Coatings Enriched with Copper on CP Titanium Grade 2 under Plasma Electrolytic Oxidation
(Journal article; Peer reviewed, 2019)In the present paper, coatings obtained on CP Titanium Grade 2 samples by Plasma Electrolytic Oxidation (PEO) in electrolyte containing concentrated phosphoric acid H3PO4 with copper nitrate Cu(NO3)2∙3H2O, are studied with ... -
Fabrication of Diffractive Honeycomb Structures on Silicon Using Photolithography and Maskless Aligner and Investigation of Optical and Electrical Properties of the Structures
(Master thesis, 2018)Surface texturing is an important method for increasing absorption of light in solar cells. This is done by creating surface structures that increase the optical path-length of photons within the cell, through light-trapping ... -
