Contractive projections in Paley-Wiener spaces
(Peer reviewed; Journal article, 2023)Let S1 and S2 be disjoint finite unions of parallelepipeds. We describe necessary and sufficient conditions on the sets S1, S2 and exponents p such that the canonical projection P from PWPS1US2 to PWPS1 is a contraction. -
A note on Real line bundles with connection and Real smooth Deligne cohomology
(Peer reviewed; Journal article, 2024-06)We define a Real version of smooth Deligne cohomology for manifolds with involution which interpolates between equivariant sheaf cohomology and smooth imaginary-valued forms. Our main result is a classification of Real ... -
Completeness of certain exponential systems and zeros of lacunary polynomials

Identification of nonlinear conservation laws for multiphase flow based on Bayesian inversion
(Peer reviewed; Journal article, 2023)Conservation laws of the generic form ct+f(c)x=0 play a central role in the mathematical description of various engineering related processes. Identification of an unknown flux function f(c) from observation data in space ... -

Et matematisk bevis på at det alltid er vindstille et sted.
(Bachelor thesis, 2024)I denne avhandlingen blir sentrale temaer innen topologi, algebra og analyse brukt til å bevise at det alltid er vindstille et sted på jorden. Analysen baserer seg på en topologisk betraktning av jorden som en sfære og ... -
Gradient Descent Methods for Training Neural Networks
(Bachelor thesis, 2024)This thesis explore algorithms to optimize the training process of a neural network for deep learning purposes, where the focus will be on gradient descent algorithms such as SGD ("Stochastic Gradient Descent") and ADAM ... -
Ripening of Capillary-Trapped CO2 Ganglia Surrounded by Oil and Water at the Pore Scale: Impact of Reservoir Pressure and Wettability
(Peer reviewed; Journal article, 2024-05)Mass transfer by Ostwald ripening can impact the life and volume of capillary-trapped CO2 in the subsurface. CO2 storage in depleted hydrocarbon reservoirs encounters various preferences for wetting of the porous rock, ... -
Effect of annealing on the electrical resistivity of Kondo lattice CeRh2Ga2
(Peer reviewed; Journal article, 2024-04)CeRh2Ga2, which crystallizes in CaBe2Ge2-type primitive tetragonal structure (space group P4/nmm), is known to exhibit Kondo lattice heavy fermion behavior and is proposed to be a potential candidate for Weyl-Kondo semimetal ... -
Shape Statistics via Skeletal Structures
(PhD thesis UiS; 781, Doctoral thesis, 2024)Statistical shape analysis has emerged as a crucial tool for medical researchers and clinicians to study medical objects such as brain subcortical structures. The insights gained from such analyses hold immense potential ... -
In medium static quark anti-quark potential from lattice QCD
(PhD thesis UiS; 775, Doctoral thesis, 2024)In this thesis we present recent progress in the quest to study the properties of the quark gluon plasma in relativistic heavy ion collisions through a better understanding of the binding of heavy quark and anti-quark pairs ... -
Importance of endocrine treatment adherence and persistence in breast cancer survivorship: a systematic review
(Peer reviewed; Journal article, 2023)Purpose Adjuvant endocrine treatment is essential for treating luminal subtypes of breast cancer, which constitute 75% of all breast malignancies. However, the detrimental side effects of treatment make it difficult for ... -
Heart rate and QRS duration as biomarkers predict the immediate outcome from pulseless electrical activity
(Peer reviewed; Journal article, 2023)Introduction Pulseless electrical activity (PEA) is commonly observed in in-hospital cardiac arrest (IHCA). Universally available ECG characteristics such as QRS duration (QRSd) and heart rate (HR) may develop differently ... -
Open-quantum-systems approach to in-medium heavy quarkonium dynamics
(Peer reviewed; Journal article, 2023)Heavy quarkonium continues to play a central role in the study of nuclear matter under extremes of temperature and density in relativistic heavy-ion collisions. In this talk I report on recent developments in the theoretical ... -
An Investigation of Second-Order Finite Volume Methods for Field-scale Reservoir Simulation
(PhD thesis UiS;, Doctoral thesis, 2024)This thesis focuses on improving the accuracy of numerical simulation of flow in subsurface reservoirs by using second-order finite volume methods. The first-order finite volume method, commonly used in reservoir simulation, ... -
New tests for trend in time censored recurrent event data
(Peer reviewed; Journal article, 2024)We consider testing for trend in recurrent event data. More precisely, for such data we consider testing of the null hypothesis of data coming from a renewal process. The new tests are essentially obtained by considering ... -
Pulsar timing array stochastic background from light Kaluza-Klein resonances
(Peer reviewed; Journal article, 2023-11)We investigate the potential of the warped extradimension framework as an explanation for the recently observed stochastic gravitational background at nHz frequencies in pulsar timing arrays (PTA). Our analysis reveals ... -
