Sample size requirements for agreement studies
(Masteroppgave/UIS-TN-IMF/2019;, Master thesis, 2019-06)This thesis examines requirements of subject sample size while planning a medical experiment, describes some known types of measures of inter-rater agreement and discovers some new useful results in this study area. The ... -
Scattering amplitudes of massive Nambu-Goldstone bosons
(Journal article; Peer reviewed, 2018-01)Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ... -
Science AMA Series: Ask the Society of Environmental Toxicology and Chemistry (SETAC) anything about Pharmaceuticals in the environment!
(Journal article, 2017)The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential ... -
Second-Order PDEs in 3D with Einstein–Weyl Conformal Structure
(Peer reviewed; Journal article, 2021)Einstein–Weyl geometry is a triple (D,g,ω) where D is a symmetric connection, [g] is a conformal structure and ω is a covector such that ∙ connection D preserves the conformal class [g], that is, Dg=ωg ; ∙ trace-free part ... -
Self-reported sleep fragmentation and sleep duration and their association with cognitive function in PROTECT, a large digital community-based cohort of people over 50
(Peer reviewed; Journal article, 2023)Objective Sleep is vital for normal cognitive function in daily life, but is commonly disrupted in older adults. Poor sleep can be detrimental to mental and physical health, including cognitive function. This study assessed ... -
Signal analysis in gravitational wave data
(PhD thesis UiS;, Doctoral thesis, 2024)In this thesis, I study the gravitational wave signals coming from compact objects on both present-stage, and future gravitational wave detectors. The thesis is based on 3 articles, which will be presented after two brief ... -
Simulations of a bubble wall interacting with an electroweak plasma
(Peer reviewed; Journal article, 2021-02)We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the ... -
Sirkelens kvadratur: En geometrisk tilnærming
(Bachelor thesis, 2022)Denne oppgaven tar for seg det klassiske problemet om sirkelens kvadratur. Sirkelens kvadratur har vært et av de vanskeligste konstruksjonsproblemene i matematikk og har fått enorm mengde oppmerksomhet i matematikkens ... -
Skeletons, Object Shape, Statistics
(Peer reviewed; Journal article, 2022)Objects and object complexes in 3D, as well as those in 2D, have many possible representations. Among them skeletal representations have special advantages and some limitations. For the special form of skeletal representation ... -
Soft Interactions in Cold Quark Matter
(Peer reviewed; Journal article, 2021-10)Accurate knowledge of the thermodynamic properties of zero-temperature, high-density quark matter plays an integral role in attempts to constrain the behavior of the dense QCD matter found inside neutron-star cores, ... -
Soft photon propagation in a hot and dense medium to next-to-leading order
(Peer reviewed; Journal article, 2023)We present the first complete calculation of the soft photon self-energy to the next-to-leading order in a hot and/or dense ultrarelativistic plasma in QED. The calculation is performed within the real-time formalism ... -
Some factors affecting the grades of technology students
(Peer reviewed; Journal article, 2017)In this study factors that affect the grades of Norwegian technology students have been investigated. The total data set contained 355.706 individual exams from 63 different engineering master programs during the 2010 to ... -
Spectral function for overoccupied gluodynamics from classical lattice simulations
(Peer reviewed; Journal article, 2019)We study the spectral properties of an overoccupied gluonic system far from equilibrium. Using classical Yang–Mills simulations and linear response theory, we determine the statistical and spectral functions. We measure ... -
Spectroscopy for asymmetric binary black hole mergers
(Peer reviewed; Journal article, 2023)Black hole spectroscopy is the proposal to observe multiple quasinormal modes in the ringdown of a binary black hole merger. In addition to the fundamental quadrupolar mode, overtones and higher harmonics may be present ... -
Spontaneous momentum dissipation and coexistence of phases in holographic Horndeski theory
(Peer reviewed; Journal article, 2019)We discuss the possible phases dual to the AdS hairy black holes in Horndeski theory. In the probe limit breaking the translational invariance, we study the conductivity and we find a nontrivial structure indicating a ... -
