WEBnm@ v2.0: Web server and services for comparing protein flexibility
(Peer reviewed; Journal article, 2014-12-30)Background: Normal mode analysis (NMA) using elastic network models is a reliable and cost-effective computational method to characterise protein flexibility and by extension, their dynamics. Further insight into the ... -
WEBnm@: a web application for normal mode analyses of proteins
(Peer reviewed; Journal article, 2005-12-30)Background: Normal mode analysis (NMA) has become the method of choice to investigate the slowest motions in macromolecular systems. NMA is especially useful for large biomolecular assemblies, such as transmembrane channels ... -

Weichselian vegetation and palaeoenvironment in western Norway and northern Russia. Evidence from pollen analytical investigations
(Doctoral thesis, 2012-06-14)This thesis focuses on the vegetation history and environmental changes in western Norway and northern Russia during the last glacial period (the Weichselian). Pollen grains deposited in lakes and bogs are used as the main ... -
The Weight Distributions of Several Classes of Cyclic Codes From APN Monomials
(Peer reviewed; Journal article, 2014-08)Let m ≥ 3 be an odd integer and p be an odd prime. In this paper, a number of classes of three-weight cyclic codes C(1,e) over Fp, which have parity-check polynomial m1(x)me (x), are presented by examining general conditions ... -
The weight spectrum of two families of Reed-Muller codes
(Journal article; Peer reviewed, 2023)We determine the weight spectra of the Reed-Muller codes RM (m− 3, m) for m ≥ 6 and RM (m − 4, m) for m ≥ 8. The technique used is induction on m, using that the sum of two weights in RM (r −1, m−1) is a weight in RM (r, ... -
Weinberg’s 3HDM potential with spontaneous CP violation
(Journal article; Peer reviewed, 2023)We study the potential of Weinberg’s Z2×Z2-symmetric three-Higgs-doublet model. The potential is designed to accommodate CP violation in the scalar sector within a gauge theory, while at the same time allowing for natural ... -
Welfare and efficiency of warm and cold waterfall (low pressure flushing) as delousing treatment of Atlantic salmon (Salmo salar)
(Master thesis, 2021-06-01)Salmonid aquaculture plays an important role in increasing global fish production and the biggest factor constraining its further growth and development in Norway is salmon lice (Lepeophtheirus salmonis). Previous projects ... -
Well-partitioned chordal graphs
(Journal article; Peer reviewed, 2022)We introduce a new subclass of chordal graphs that generalizes the class of split graphs, which we call well-partitioned chordal graphs. A connected graph G is a well-partitioned chordal graph if there exist a partition P ... -
Well-posedness and discretization for a class of models for mixed-dimensional problems with high-dimensional gap
(Journal article; Peer reviewed, 2021)In this work, we show the underlying mathematical structure of mixed-dimensional models arising from the composition of graphs and continuous domains. Such models are becoming popular in applications, in particular, to ... -
Well-Posedness for a Dispersive System of the Whitham-Boussinesq Type
(Journal article; Peer reviewed, 2020)We regard the Cauchy problem for a particular Whitham--Boussinesq system modeling surface waves of an inviscid incompressible fluid layer. We are interested in well-posedness at a very low level of regularity. We derive ... -
Well-Posedness for a Whitham–Boussinesq System with Surface Tension
(Journal article; Peer reviewed, 2020)We regard the Cauchy problem for a particular Whitham–Boussinesq system modelling surface waves of an inviscid incompressible fluid layer. The system can be seen as a weak nonlocal dispersive perturbation of the shallow ... -
Well-posedness Issues for Nonlinear Partial Differential Equations Appearing in the Modeling of Long Water Waves
(Doctoral thesis, 2018-12-18)Modelling of wave motion in a fluid is usually based on classical systems which are obtained by the hypotheses that the flow is irrotational and the bottom is even. In such a context, the influence of vorticity is entirely ... -
Well-posedness of the fully coupled quasi-static thermo-poroelastic equations with nonlinear convective transport
(Peer reviewed; Journal article, 2019-03)This paper is concerned with the analysis of the quasi-static thermo-poroelastic model. This model is nonlinear and includes thermal effects compared to the classical quasi-static poroelastic model (also known as Biot's ... -
West Spitsbergen fold and thrust belt: A digital educational data package for teaching structural geology
(Journal article; Peer reviewed, 2023)The discipline of structural geology is taking an advantage of compiling observations from multiple field sites to comprehend the bigger picture and constrain the region's geological evolution. In this study we demonstrate ... -
Wettability effects on oil recovery mechanisms in fractured chalk
(Doctoral thesis, 2007-02-02)This thesis is a part of the ongoing project, “Oil recovery from fractured chalk reservoirs”, which is a collaboration between the Reservoir Physics Group at the University of Bergen and ConocoPhillips Research Center in ... -
Wetting in Porous Media: A Nuclear Magnetic Resonance Study.
(Doctoral thesis, 2020-06-30)The purpose of this thesis has been to study mechanisms responsible for wettability alteration on reservoir minerals and then to study how surface wettability affects the distribution of immiscible liquids in porous media. ... -
Wetting of porous thin films exhibiting large contact angles
(Journal article; Peer reviewed, 2023)Porous solid films that promote large apparent contact angles are interesting systems since their wetting properties are dependent on both the surface structure and water penetration into the film. In this study, a ... -
Wetting Stability of Aged Limestone in the presence of HPAM polymer
(Master thesis, 2020-06-04)The Norwegian Petroleum Directorate required that a polymer field pilot should be performed in the Johan Sverdrup field in the second phase of the field development to confirm potential enhanced recovery potential at the ... -
What can selection experiments teach us about fisheries-induced evolution?
(Peer reviewed; Journal article, 2014-03)There is evidence that fisheries are altering the phenotypic composition of fish populations, often in ways that may reduce the value of fish stocks for the exploiters. Despite the increasing number of theoretical and field ...
