The dissolution of a miscible drop rising or falling in another liquid at low Reynolds number
(Journal article; Peer reviewed, 2023)“A basic and basically unsolved problem in fluid dynamics is to determine the evolution of rising bubbles and falling drops of one miscible liquid in another” [D. D. Joseph and Y. Y. Renardy, Fundamentals of Two-Fluid ... -
Diurnal gait fluctuations in single- and dual- task conditions
(Journal article; Peer reviewed, 2020)Gait is one of the most basic movements, and walking activity accomplished in dual task conditions realistically represents daily life mobility. Much is known about diurnal variations of gait components such as muscle ... -
Divided differences and ideals generated by symmetric polynomials

Do abnormal serum lipid levels increase the risk of chronic low back pain? The Nord-Trøndelag Health Study
(Peer reviewed; Journal article, 2014-09-18)Background: Cross-sectional studies suggest associations between abnormal lipid levels and prevalence of low back pain (LBP), but it is not known if there is any causal relationship. Objective: The objective was to determine, ... -
Does diabetes influence the probability of experiencing chronic low back pain? A population-based cohort study: the Nord-Trøndelag Health Study
(Peer reviewed; Journal article, 2019)Objective: Low back pain (LBP) is a major problem in modern society and it is important to study possible risk factors for this disorder. People with diabetes are often affected by LBP, but whether diabetes represents a ... -
Does the risk of chronic low back pain depend on age at menarche or menopause? A population-based cross-sectional and cohort study: the Trøndelag Health Study
(Journal article; Peer reviewed, 2022)Objective In most population-based studies of low back pain (LBP), women have a higher risk than men, possibly reflecting hormonal influences. The aim of this study was to explore associations between age at menarche and ... -
Domain decomposition preconditioning for non-linear elasticity problems
(Chapter; Peer reviewed, 2014)We consider domain decomposition techniques for a non-linear elasticity problem. Our main focus is on non-linear preconditioning, realized in the framework of additive Schwarz preconditioned inexact Newton (ASPIN) methods. ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach
(Peer reviewed; Journal article, 2019-03)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
Dual virtual element methods for discrete fracture matrix models
(Peer reviewed; Journal article, 2019)The accurate description of fluid flow and transport in fractured porous media is of paramount importance to capture the macroscopic behavior of an oil reservoir, a geothermal system, or a CO2 sequestration site, to name ... -

Dynamic Boolean modelling reveals the influence of energy supply on bacterial efflux pump expression
(Journal article; Peer reviewed, 2022)Antimicrobial resistance (AMR) is a global health issue. One key factor contributing to AMR is the ability of bacteria to export drugs through efflux pumps, which relies on the ATP-dependent expression and interaction of ... -
Dynamic Capillary Effects in the Simulation of Flow and Transport in Porous Media: A New Linearisation Method
(Master thesis, 2014-12-25)In this thesis mathematical models with and without dynamic capillary effects are developed to model water flow and solute transport through a porous medium. The system of equations are discretised using the finite volume ... -
Dynamic modelling of biochemical reaction networks and sampling methods for constraint-based models
(Doctoral thesis, 2021-02-05)This dissertation is a partial fulfillment of the requirements for the degree of Doctor of Philosophy (PhD). This study is carried out at the Department of Mathematics, University of Bergen. The subject of the thesis is ... -
The dynamics of trait variance in multi-species communities: Multi-species trait variance dynamics
(Journal article; Peer reviewed, 2020)In this paper, we establish the explicit connection between deterministic trait-based population-level models (in the form of partial differential equations) and species-level models (in the form of ordinary differential ... -
Early prediction of response to radiotherapy and androgen-deprivation therapy in prostate cancer by repeated functional MRI: a preclinical study
(Peer reviewed; Journal article, 2011-06-08)Background: In modern cancer medicine, morphological magnetic resonance imaging (MRI) is routinely used in diagnostics, treatment planning and assessment of therapeutic efficacy. During the past decade, functional imaging ... -
Ecological and evolutionary dynamics of interconnectedness and modularity
(Peer reviewed; Journal article, 2018-01-23)In this contribution, we develop a theoretical framework for linking microprocesses (i.e., population dynamics and evolution through natural selection) with macrophenomena (such as interconnectedness and modularity within ... -
The Effect of Environmental Stressors on Tinnitus: A Prospective Longitudinal Study on the Impact of the COVID-19 Pandemic
(Journal article; Peer reviewed, 2020-08)Tinnitus, the perception of sound in the absence of a corresponding sound, and the distress caused by it, is rarely a static phenomenon. It rather fluctuates over time depending on endogenous and exogenous factors. The ... -
Effect of Erroneous Representation of Location and Orientation of EM Receivers for Monitoring of Submarine Petroleum Reservoirs
(Master thesis, 2009-06-02)The receivers in electromagnetic monitoring should optimally be placed exactly in the same location during every single acquisition. However, for technological and economical reasons, the receivers are currently brought ... -
Effective permeability of deformation bands in fault damage zones – Can deformation bands reduce the risk of fault leakage?
(SINTEF Proceedings;7, Chapter, 2021)Faults are major geological structures that can dominate the flow paths in subsurface reservoirs by, e.g., connecting otherwise unconnected layers. In CO2 storage sites where the faults act as the main structural trap, the ... -
Effective Preconditioners for Mixed-Dimensional Scalar Elliptic Problems
(Journal article; Peer reviewed, 2023)Discretization of flow in fractured porous media commonly lead to large systems of linear equations that require dedicated solvers. In this work, we develop an efficient linear solver and its practical implementation for ...
