Sverdrup critical depth and the role of water clarity in Norwegian Coastal Water
(Peer reviewed; Journal article, 2015-02-25)The critical depth concept was first recognized by Gran and Braarud (1935). During summer, in the Bay of Fundy, they observed an unexpected no bloom situation. Their interpretation was that high amounts of detritus of ... -
Swampland de Sitter conjectures in no-scale supergravity models
(Journal article; Peer reviewed, 2021)It is challenging to construct explicit and controllable models that realize de Sitter solutions in string compactifications. This difficulty is the main motivation for the refined de Sitter conjecture and the trans-Planckian ... -
Swarm in situ observations of F region polar cap patches created by cusp precipitation
(Peer reviewed; Journal article, 2015-02-26)High-resolution in situ measurements from the three Swarm spacecraft, in a string-of-pearls configuration, provide new insights about the combined role of flow channel events and particle impact ionization in creating F ... -
Swimming with the fishes: validating drift diving to identify farmed Atlantic salmon escapees in the wild
(Peer reviewed; Journal article, 2019)Escaped farmed Atlantic salmon Salmo salar interbreeding with wild conspecifics represents a threat to the genetic integrity and viability of wild populations. Therefore, it is necessary to accurately quantify escapees in ... -
Switching of INCENP paralogs controls transitions in mitotic chromosomal passenger complex functions
(Peer reviewed; Journal article, 2019)A single inner centromere protein (INCENP) found throughout eukaryotes modulates Aurora B kinase activity and chromosomal passenger complex (CPC) localization, which is essential for timely mitotic progression. It has been ... -
Symmetric Ciphers for Fully Homomorphic Encryption
(Master thesis, 2020-08-28)Fully homomorphic encryption is the latest addition to the world of cryptography. It is a type of encryption that allows operations to be done on ciphertexts, which is not possible with traditional encryption. The field ... -
Symmetric spaces and Lie triple systems in numerical analysis of differential equations
(Peer reviewed; Journal article, 2014-03)A remarkable number of different numerical algorithms can be understood and analyzed using the concepts of symmetric spaces and Lie triple systems, which are well known in differential geometry from the study of spaces of ... -
Symmetric waves are traveling waves of some shallow water scalar equations
(Journal article; Peer reviewed, 2023)Following a straightforward proof for symmetric solutions to be traveling waves by Pei (Exponential decay and symmetry of solitary waves to Degasperis-Procesi equation. Journal of Differential Equations. 2020;269(10):7730-7749), ... -
Symmetries and mass degeneracies in the scalar sector
(Peer reviewed; Journal article, 2019-01-04)We explore some aspects of models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. In Higgs sectors with two scalar doublets, the exact degeneracy of scalar masses, ... -
Symmetries of the 2HDM: an invariant formulation and consequences
(Journal article; Peer reviewed, 2021)Symmetries of the Two-Higgs-Doublet Model (2HDM) potential that can be extended to the whole Lagrangian, i.e. the CP-symmetries CP1, CP2, CP3 and the Higgs-family symmetries Z2, U(1) and SO(3) are discussed. Sufficient and ... -
Symmetry and mass degeneration in multi-Higgs-doublet models
(Peer reviewed; Journal article, 2011-07-05)We investigate possible symmetry properties of the scalar sector of Multi-Higgs-Doublet Models, and, to some extent, the generalization of such models to gauge groups other than SU(2)_L × U(1)_Y . In models with C (charge ... -
Symmetry and simplicity spontaneously emerge from the algorithmic nature of evolution
(Journal article; Peer reviewed, 2022)Engineers routinely design systems to be modular and symmetric in order to increase robustness to perturbations and to facilitate alterations at a later date. Biological structures also frequently exhibit modularity and ... -
Syn-rift sediment gravity flow deposition on a Late Jurassic fault-terraced slope, northern North Sea
(Journal article; Peer reviewed, 2021)Structurally controlled bathymetry in rifts has a significant influence on sediment routing pathways and depositional architecture of sediment gravity flow deposits. In contrast to rift segments characterized by crustal-scale ... -
Synchronicity from synchronized chaos
(Peer reviewed; Journal article, 2015-03-27)The synchronization of loosely-coupled chaotic oscillators, a phenomenon investigated intensively for the last two decades, may realize the philosophical concept of “synchronicity”—the commonplace notion that related ... -
Synechococcus in the Atlantic Gateway to the Arctic Ocean
(Peer reviewed; Journal article, 2016-10-05)Increasing temperatures, with pronounced effects at high latitudes, have raised questions about potential changes in species composition, as well as possible increased importance of small-celled phytoplankton in marine ... -
The synergistic interaction of thermal stress coupled with overstocking strongly modulates the transcriptomic activity and immune capacity of rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2020)The objective of the present study is to identify and evaluate informative indicators for the welfare of rainbow trout exposed to (A) a water temperature of 27 °C and (B) a stocking density of 100 kg/m3 combined with a ... -

(Master thesis, 2018-06-20)This experimental thesis is a part of an ongoing CO2-foam project lead by the Reservoir Physics group at the Department of Physics and Technology, University of Bergen. The main thesis objective was to investigate the ... -
Synoptic conditions and frontal dynamics during Cold Air Outbreaks in the Norwegian and Barents Sea
(Master thesis, 2018-08-30)Cold Air Outbreaks (CAOs) in the Norwegian and Barents Sea are investigated using ERA Interim. The focus is on the synoptic conditions, heat fluxes, potential temperature tendencies and the frontogenesis at the onset of ... -
Synoptic Conditions and Moisture Sources Actuating Extreme Precipitation in Nepal
(Peer reviewed; Journal article, 2017-12)Despite the vast literature on heavy‐precipitation events in South Asia, synoptic conditions and moisture sources related to extreme precipitation in Nepal have not been addressed systematically. We investigate two types ...
