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 ... -
Synergy of Nanoparticles and Surfactants for CO2 Foam Enhanced Oil Recovery and CO2 Storage in Carbonates
(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 ... -
