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 ... -
Effects of a parent-administered exercise program in the neonatal intensive care unit: Dose does matter-a randomized controlled trial
(Journal article; Peer reviewed, 2020)Background Despite the risk of delayed motor development in infants born preterm, knowledge about interventions in the neonatal intensive care unitt (NICU) and the effects of dosing is sparse. Objective The objectives ... -
Effects of a surface layer cross-flow and slope steepness on the rate of descent of dense water flows along a slope
(Journal article; Peer reviewed, 2024)The pathways and mixing in dense water overflows have been addressed in a range of numerical studies based on the DOME (Dynamics of Overflow Mixing and Entrainment) setup. These studies are motivated by overflows such as ... -
Effects of bottom drag and shelf slope steepnes on the currents along the shelf slope at Ormen Lange
(Department of Applied Mathematics report, Research report, 2001-12) -
Effects of complex neck therapy – kinesiotherapy and interspinal muscles massage – on tinnitus
(Journal article, 2023)Introduction: Past studies have shown connections between the somatosensory system (the neck and temporomandibular joint region) and the auditory system. It is therefore likely that tinnitus patients might benefit from ... -
Effects of thermally-dependent rock parameters on fracture reactivation
(Master thesis, 2019-07-09)The slip tendency is an important tool to measure fracture reactivation in thecontext of subsurface engineering applications. In this thesis, the effects of thermally-dependent rock parameters such as Young’s modulus on ... -

Efficient Global Minimization for the Multiphase Chan-Vese Model of Image Segmentation
(Peer reviewed; Journal article, 2009)The Mumford-Shah model is an important variational image segmentation model. A popular multiphase level set approach, the Chan-Vese model, was developed as a numerical realization by representing the phases by several ... -
Efficient global minimization methods for variational problems in imaging and vision
(Doctoral thesis, 2011-08-19)Energy minimization has become one of the most important paradigms for formulating image processing and computer vision problems in a mathematical language. Energy minimization models have been developed in both the ... -
An efficient software framework for performing industrial risk assessment of leakage for geological storage of CO2
(Peer reviewed; Journal article, 2011)In response to anthropogenic CO2 emissions, geological storage has emerged as a practical and scalable bridge technology while renewables and other environmentally friendly energy production methods mature. While an ... -
Efficient Solvers for Nonstandard Models for Flow and Transport in Unsaturated Porous Media
(Journal article; Peer reviewed, 2022)We study several iterative methods for fully coupled flow and reactive transport in porous media. The resulting mathematical model is a coupled, nonlinear evolution system. The flow model component builds on the Richards ... -
Efficient vasculature investment in tissues can be determined without global information
(Journal article; Peer reviewed, 2020)Cells are the fundamental building blocks of organs and tissues. Information and mass flow through cellular contacts in these structures is vital for the orchestration of organ function. Constraints imposed by packing and ... -
Efficient water table evolution discretization using domain transformation
(Peer reviewed; Journal article, 2017-02)Domain transformation methods are useful techniques for solving problems on non-stationary domains. In this work, we consider the evolution of the water table in an unconfined aquifer. This nonlinear, time-dependent problem ... -
