Identification of the flux function of nonlinear conservation laws with variable parameters
(Peer reviewed; Journal article, 2023-09)Machine learning methods have in various ways emerged as a useful tool for modeling the dynamics of physical systems in the context of partial differential equations (PDEs). Nonlinear conservation laws (NCLs) of the form ... -
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 ... -
Importance Sampling-based Transport Map Hamiltonian Monte Carlo for Bayesian Hierarchical Models
(Peer reviewed; Journal article, 2021-06)We propose an importance sampling (IS)-based transport map Hamiltonian Monte Carlo procedure for performing a Bayesian analysis in nonlinear high-dimensional hierarchical models. Using IS techniques to construct a transport ... -
Improved background subtraction and a fresh look at jet sub-structure in JEWEL
(Peer reviewed; Journal article, 2022)Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed ... -
Improved Gauss law model and in-medium heavy quarkonium at finite density and velocity
(Peer reviewed; Journal article, 2020-03)We explore the in-medium properties of heavy-quarkonium states at finite baryochemical potential and finite transverse momentum based on a modern complex-valued potential model. Our starting point is a novel, rigorous ... -
In-medium kinetic theory of D mesons and heavy-flavor transport coefficients
(Peer reviewed; Journal article, 2022)We extend the kinetic theory of D mesons to accommodate thermal and off-shell effects due to the medium modification of the heavy-meson spectral functions. From the Kadanoff-Baym approach we derive the off-shell Fokker-Planck ... -
Information in Local Curvature: Three Papers on Adaptive Methods in Computational Statistics
(PhD thesis UiS;562, Doctoral thesis, 2020-11)Advanced statistical computations have become increasingly important, as with the increased flexibility of models capturing complex relationships in new data and use-cases, comes increased difficulties of fitting procedures ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... -
Inkludering av FNs bærekraftsmål i kjemiutdanningene Embracing the UN sustainability goals into the Chemistry educations
(Master thesis, 2022)Tema for denne masteroppgaven er utdanning for bærekraftig utvikling, og problemstillingen som belyses er «Hvordan kan Universitetet i Stavanger inkludere FNs bærekraftsmål i kjemiutdanningene?» Bakgrunnen for denne ... -

Interpolation of weighted extremal functions
(Peer reviewed; Journal article, 2021-03)An approach to interpolation of compact subsets of Cn, including Brunn–Minkowski type inequalities for the capacities of the interpolating sets, was developed in [8] by means of plurisubharmonic geodesics between relative ... -
Introduction to graph theory: Classroom potential of core concepts
(Bachelor thesis, 2021)This thesis is an introduction to graph theory with its core concepts and formulas, including a look at the mostly untapped classroom potential of this field of mathematics. Included are in-depth explanations and proofs ... -
Introduction to Supersymmetry
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020-06)This thesis covers the mathematical foundations of supersymmetry, and looks at the simplest non-trivial example of supersymmetry in physics, the Wess-Zumino model. On the way we will also explicitly calculate the Poincar´e ... -
Invariant characterization of Szekeres models with positive cosmological constant
(Peer reviewed; Journal article, 2022-07)We present an invariant characterization of black holes in the Szekeres spacetime with positive cosmological constant. In the formation of the black holes, we locate geometric horizons, and show that they coincide with the ... -
An Invariant Characterization of the Levi-Civita Spacetimes
(Peer reviewed; Journal article, 2021-08)In the years 1917–1919 Tullio Levi-Civita published a number of papers presenting new solutions to Einstein’s equations. This work, while partially translated, remains largely inaccessible to English speaking researchers. ... -
Investigation of crystal field, magnetic frustration and magnetization reversal effects in 4f and 3d oxides
(PhD thesis UiS;, Doctoral thesis, 2022-09)This thesis deals with the investigation of single-ion excitations, magnetic frustration, and magnetization reversal phenomena. We have employed neutron scattering, μ+SR, and computational methods for these studies. Inverse ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
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, ... -
Involutions of Quadrics
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020-07-09)In the introductory chapter, we will explain briefly what all this work is about. First is worthy to mention that the most included area is algebraic geometry, which of course is a combination of algebra and linear algebra. ... -
Konvergens av Fourier rekker i Hilbert rom - en introduksjon til sampling teori.
(Master thesis, 2021)Klassisk kalkulus som omhandler studie av kontinuerlig forandring kan spores helt tilbake til 1600 tallet. Derimot mangler klassisk kalkulus evnen til å tilstrekkelig transformere naturlige prosesser som lyd, radiobølger ...
