Chitin synthesis in the salmon louse Lepeophtheirus salmonis
(Doctoral thesis, 2021-06-18)The salmon louse Lepeophtheirus salmonis is a parasitic copepod that lives and feeds on Atlantic salmon (Salmo salmar). At present, this parasite is the number one threat to the Norwegian aquaculture. The density of salmons ... -
Archaeological bird remains from Norway as a means to identify long-term patterns in a Northern European avifauna
(Doctoral thesis, 2021-06-18)Birds are currently facing a biodiversity crisis. Seabirds, birds in agricultural landscapes, and montane birds are particularly vulnerable to extinction. Whilst their modern distributions are well studied, how past events ... -
Chitin synthases are critical for reproduction, molting, and digestion in the salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2021-01-13)Chitin synthase (CHS) is a large transmembrane enzyme that polymerizes Uridine diphosphate N-acetylglucosamine into chitin. The genomes of insects often encode two chitin synthases, CHS1 and CHS2. Their functional roles ... -
A Polynomial Kernel for Line Graph Deletion
(Journal article; Peer reviewed, 2020)The line graph of a graph G is the graph L(G) whose vertex set is the edge set of G and there is an edge between e,f ∈ E(G) if e and f share an endpoint in G. A graph is called line graph if it is a line graph of some ... -
The CP-symmetries of the 2HDM
(Journal article; Peer reviewed, 2020)We discuss the three different classes of CP-symmetries that can be realized in a two-Higgs-doublet model, CP1, CP2 and CP3. We express conditions for realizing these symmetries in terms of masses and couplings of the ... -
Reconstructing ribosomal genes from large scale total RNA meta-transcriptomic data
(Journal article; Peer reviewed, 2020-03-13)Motivation Technological advances in meta-transcriptomics have enabled a deeper understanding of the structure and function of microbial communities. ‘Total RNA’ meta-transcriptomics, sequencing of total reverse transcribed ... -
Transversals of longest paths
(Journal article; Peer reviewed, 2020-03)Let lpt(G) be the minimum cardinality of a transversal of longest paths in G, that is, a set of vertices that intersects all longest paths in a graph G. There are several results in the literature bounding the value of ... -
Mass balance of the Greenland Ice Sheet from 1992 to 2018
(Journal article; Peer reviewed, 2019-12-10)The Greenland Ice Sheet has been a major contributor to global sea-level rise in recent decades1,2, and it is expected to continue to be so3. Although increases in glacier flow4,5,6 and surface melting7,8,9 have been driven ... -

Energetic electron precipitation of pulsating aurorae and their mesospheric effects
(Doctoral thesis, 2021-06-17)Pulsating aurorae (PsAs) are low-intensity diffuse type aurora, which switches on and off with a quasi-periodic oscillation period from a few seconds to ~ 10 seconds. They are predominantly observed after midnight magnetic ... -
Effect of tag weight on vertical behavior of Atlantic salmon (Salmo salar) smolts: an overlooked tag effect?

Spin dynamics in photon ionization processes in hydrogenic atoms
(Master thesis, 2021-05-11)Spin effects in hydrogenic atoms to relativistic order 1/c^2 have been considered and modeled in three different gauges, two of which have been used extensively in the dipole approximation to calculate cross sections in ... -
Measurements of inclusive jet spectra in pp and central Pb-Pb collisions at √sNN=5.02TeV
(Journal article; Peer reviewed, 2020)This article reports measurements of the p T -differential inclusive jet cross section in p p collisions at √ s = 5.02 TeV and the p T -differential inclusive jet yield in Pb-Pb 0–10% central collisions at √ s N N = 5.02 ... -
Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review
(Journal article; Peer reviewed, 2020)This review was prompted by reports of unusually large numbers of sea lice tentatively identified as Caligus elongatus infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in ... -
Ontogenetic movements of cod in Arctic fjords and the Barents Sea as revealed by otolith microchemistry
(Journal article; Peer reviewed, 2020-04-06)The distribution of Atlantic cod (Gadus morhua) in northern Norwegian waters is expanding eastward and northward in the Barents Sea and along western Svalbard. In the Arctic fjords of Svalbard, cod has become abundant, but ... -
Non-linear flow modes of identified particles in Pb-Pb collisions at √sNN = 5.02 TeV
(Journal article; Peer reviewed, 2020)The pT-differential non-linear flow modes, v4,22, v5,32, v6,33 and v6,222 for π±, K±, K0S , p + p¯¯¯, Λ + Λ¯¯¯¯ and ϕ-meson have been measured for the first time at sNN−−−√ = 5.02 TeV in Pb-Pb collisions with the ALICE ... -
Multiplicity dependence of light (anti-)nuclei production in p–Pb collisions at √sNN=5.02 TeV
(Journal article; Peer reviewed, 2020)The measurement of the deuteron and anti-deuteron production in the rapidity range −1 < y < 0 as a function of transverse momentum and event multiplicity in p–Pb collisions at √sNN = 5.02 TeV is presented. (Anti-)deuterons ... -
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 ... -
Influence of Diabatic Effects and Tropopause Structure on Baroclinic Development
(Doctoral thesis, 2021-06-10)Midlatitude cyclones play an important role in midlatitude weather and global climate. While baroclinic instability is the dominant mechanism for their intensification, midlatitude cyclone development is also influenced ... -
