Separating blue whiting (Micromesistius poutassou Risso, 1826) from myctophid targets using multi-frequency methods
(Master thesis, 2008)Blue whiting (Micromesistius poutassou Risso, 1826) is a physoclists species, widely distributed in the Barents Sea, Norwegian Sea and Mediterranean Sea. They appear on the continental slope and shelf, in high concentration ... -
Separating Exceptional Concerns
(IEEE conference proceedings, Chapter; Peer reviewed, 2012)Traditional error handling mechanisms, including exceptions, have several weaknesses that interfere with maintainability, flexibility and genericity in software: Error code is tangled with normal code; reporting is tangled ... -
Separating NADH and NADPH fluorescence in live cells and tissues using FLIM
(Peer reviewed; Journal article, 2014-05-29)NAD is a key determinant of cellular energy metabolism. In contrast, its phosphorylated form, NADP, plays a central role in biosynthetic pathways and antioxidant defence. The reduced forms of both pyridine nucleotides are ... -
Separation and quantification of ionospheric convection sources: 1. A new technique
(Peer reviewed; Journal article, 2019-07-04)This paper describes a novel technique that allows separation and quantification of different sources of convection in the high‐latitude ionosphere. To represent the ionospheric convection electric field, we use the Spherical ... -
Separation and quantification of ionospheric convection sources: 2. The dipole tilt angle influence on reverse convection cells during northward IMF
(Peer reviewed; Journal article, 2019-07-04)This paper investigates the influence of Earth's dipole tilt angle on the reverse convection cells (sometimes referred to as lobe cells) in the Northern Hemisphere ionosphere during northward IMF, which we relate to ... -
Sequence analysis and spatiotemporal developmental distribution of the Cat-1-type transporter slc7a1a in zebrafish (Danio rerio)
(Journal article; Peer reviewed, 2020)Cationic amino acid transporter 1 (Cat-1 alias Slc7a1) is a Na+-independent carrier system involved in transport and absorption of the cationic amino acids lysine, arginine, histidine, and ornithine and has also been shown ... -
Sequence divergence and diversity suggests ongoing functional diversification of vertebrate NAD metabolism
(Peer reviewed; Journal article, 2014-11)NAD is not only an important cofactor in redox reactions but has also received attention in recent yearsbecause of its physiological importance in metabolic regulation, DNA repair and signaling. In contrast tothe redox ... -
The sequence stratigraphic development of the Late Permian Kapp Starostin Formation, central Spitsbergen
(Master thesis, 2016-06-01)This study investigated the sedimentology and the sequence stratigraphy of the Late Permian Kapp Starostin Formation in the southwestern part of Dickson Land, central Spitsbergen. The underlying Gipshuken Formation and the ... -
Sequence tiling as a strategy to map novel genotype-dependent cis-regulation in the HIBCH locus (2q32.2)
(Master thesis, 2021-06-01) -
Sequence variation in four mitochondrial genes of the salmon louse Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2006-03-02)A total of 210 Lepeophtheirus salmonis collected from 7 locations (Scotland, Russia, Canada, Japan and 3 locations in Norway), were screened for sequence variation in 4 mitochondrial genes; ATPase subunit 6 (A6), Cytochrome ... -
Sequence-based enzyme discovery from marine microbial diversity : Multiple approaches for the heterologous expression of genes in Escherichia coli
(Doctoral thesis, 2021-06-09)The vast biodiversity of marine environments is increasingly being recognized as a source for new enzymes with value in both basic research and applications within biotechnology. In this project, the major aim was to ... -
Sequences and Linear Codes from Highly Nonlinear Functions
(Doctoral thesis, 2014-06-16)Due to optimal nonlinearity and differential uniformity, perfect nonlinear (PN) and almost perfect nonlinear (APN) functions are of great importance in cryptography. It is interesting that they also define optimal objects ... -
Sequential Data Assimilation in High Dimensional Nonlinear Systems
(Doctoral thesis, 2011-10-21)Since its introduction in 1994, the ensemble Kalman filter (EnKF) has gained a lot of attention as a tool for sequential data assimilation in many scientific areas. Due to its computationally fast and easy to implement ... -
Sequential extraction procedure to obtain the composition of terrigenous detritus in marine sediments
(Journal article; Peer reviewed, 2020)The geochemical and isotopic composition of terrigenous clays from marine sediments can provide important information on the sources and pathways of sediments. In order to extract the detrital signal from bulk marine ... -
Sequential growth of deformation bands in carbonate grainstones in the hangingwall of an active growth fault: Implications for deformation mechanisms in different tectonic regimes
(Peer reviewed; Journal article, 2016-09)Deformation bands in porous sandstones have been extensively studied for four decades, whereas comparatively less is known about deformation bands in porous carbonate rocks, particularly in extensional settings. Here, we ... -

Sequential Monte Carlo Methods in Practice
(Master thesis, 2023-11-27)With the continuous increase in computational power, sequential Monte Carlo methods have emerged as an efficient technique for estimating unknown data in a world consisting of nonlinearity and non-Gaussianity. In this ... -
Sequential multilevel assimilation of inverted seismic data
(Journal article; Peer reviewed, 2023)We consider estimation of absolute permeability from inverted seismic data. Large amounts of simultaneous data, such as inverted seismic data, enhance the negative effects of Monte Carlo errors in ensemble-based Data ... -
