Dark energy from quantum gravity
(Master thesis, 2009) The thesis consists of two parts, where the last one tries to model the evolution of the universe by using a scalar field. Within this class of models there is a huge amount of freedom and few simple restrictions. ... -
Dark matter candidates and their indirect detection
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:152, Doctoral thesis, 2010) -
Dark Matter Contribution to the Isotropic Extragalactic Gamma-Ray Background
(Master thesis, 2011)This thesis looks into the possibilities of finding a signal from dark matter annihilation in the isotropic extragalactic gamma-ray background radiation (EGBR), and compares the the results with data from the Fermi Large ... -
Data on atomic structures of precipitates in an Al-Mg-Cu alloy studied by high resolution transmission electron microscopy and first-principles calculations
(Journal article; Peer reviewed, 2021)The dataset refers to the research article “Precipitation processes and structural evolutions of various GPB zones and two types of S phases in a cold-rolled Al-Mg-Cu alloy” [1]. Transmission electron microscopy (TEM) and ... -
Dc Josephson Effect in Altermagnets
(Journal article; Peer reviewed, 2023)The ability of magnetic materials to modify superconductors is an active research area for possible applications in thermoelectricity, quantum sensing, and spintronics. We consider the fundamental properties of the Josephson ... -
Deciphering the Electronic Transitions of Thiophene-Based Donor-Acceptor-Donor Pentameric Ligands Utilized for Multimodal Fluorescence Microscopy of Protein Aggregates.
(Journal article; Peer reviewed, 2020)Anionic pentameric thiophene acetates can be used for fluorescence detection and diagnosis of protein amyloid aggregates. Replacing the central thiophene unit by benzothiadiazole (BTD) or quinoxaline (QX) leads to large ... -
Decoding of Algebraic Geometry Codes
(Master thesis, 2011)Codes derived from algebraic curves are called algebraic geometry (AG) codes. They provide a way to correct errors which occur during transmission of information. This paper will concentrate on the decoding of algebraic ... -
Deep Generative Models for MRI Data Synthesis of Patients with Brain Metastases
(Master thesis, 2024)Hensikt: Fremskritt innen generativ kunstig intelligens (KI) kan bidra til å løse problemet med data tilgjengelighet i det medisinske feltet. Medisinske datasett er ofte små, et faktum som begrenser utviklingen og verdien ... -
Deep Learning For Automatic Segmentation Of Rectal Cancer On Magnetic Resonance Images From Two Independent Cohorts
(Master thesis, 2021)Heniskt: Inntegning av kreftsvulstvolumet er en viktig del av både kvantitativ bildeanalyse og strålebehandling. Dette er en tidkrevende oppgave som er forbundet med usikkerhet grunnet interobservatørvariabilitet. Det ville ... -
Deep learning image segmentation and automatic treatment planning in breast cancer radiotherapy
(Master thesis, 2021)Bakgrunn og formål: Behandlingsplanlegging og tilhørende segmentering av risikoorgan og målvolum for stråleterapi blir i dag mer eller mindre gjort manuelt. Prosessene er derfor tidkrevende og utsatt for variasjon mellom ... -
Deep Learning-Based Intravoxel Incoherent Motion Modelling of Diffusion-Weighted MRI in Head and Neck Cancer: In Silico and In Vivo Studies
(Master thesis, 2024)Bakgrunn: Modellering av intravoksel inkoherente bevegelser (IVIM) i diffusjonsvektet avbildning (DWI), som er en type funksjonell magnetisk resonanstomografi (MRI), gir muligheter for å persontilpasse strålebehandling for ... -
Deep neural network enabled corrective source term approach to hybrid analysis and modeling
(Peer reviewed; Journal article, 2022)In this work, we introduce, justify and demonstrate the Corrective Source Term Approach (CoSTA)—a novel approach to Hybrid Analysis and Modeling (HAM). The objective of HAM is to combine physics-based modeling (PBM) and ... -
Degradation and Stability of PBCA and POCA Nanoparticles
(Master thesis, 2013)Nanoparticles represent promising carriers for controlled drug delivery. In this project threedifferent intruments: Zetasizer, Nanosight and Gas Chromatography, have been used to detect and analyse degradation of monodisperse ... -
Degradation of insulin amyloid by antibiotic minocycline and formation of toxic intermediates
(Peer reviewed; Journal article, 2021)Insulin balls, localized insulin amyloids formed at subcutaneous insulin-injection sites in patients with diabetes, cause poor glycemic control owing to impairments in insulin absorption. Our previous study has shown that ... -
Degradation of the chemotherapy drug 5-fluorouracil on medical-grade silver surfaces
(Journal article; Peer reviewed, 2018) -
Degradation of the Chemotherapy Drug 5-Fluorouracil on Surfaces
(Master thesis, 2015)The catalytic effect of different materials concerning degradation of the chemo therapy drug 5-Fluorouracil (5-Fu) has been studied using X-ray Photoelectron Spectroscopy and X-ray Absorption Spectroscopy. The materials ... -
