Scale size-dependent characteristics of the nightside aurora
(Peer reviewed; Journal article, 2017-02)We have determined the spatiotemporal characteristics of the magnetosphere-ionosphere (M-I) coupling using auroral imaging. Observations at fixed positions for an extended period of time are provided by a ground-based ... -
Scattering from spheres and cylinders - revisited
(Chapter, 2006)Backscattering of sound from elastic spheres is commonly applied for calibration of acoustic systems. Measurements on the "form function" of various tungsten carbide spheres turned out not to match simulations based on ... -
Scattering studies with low-energy kaon-proton femtoscopy in proton-proton collisions at the LHC
(Journal article; Peer reviewed, 2020)The study of the strength and behavior of the antikaon-nucleon (¯KN) interaction constitutes one of the key focuses of the strangeness sector in low-energy quantum chromodynamics (QCD). In this Letter a unique high-precision ... -
Scenario based analysis of fire escalation in a gas process plant
(Master thesis, 2013-05-28)This study takes place on a medium sized gas process plant called reference plant. In this thesis several escalation scenarios, as well as gas dispersion, is evaluated through Kameleon KFX and Vessfire. It has previously ... -
Schrödinger formulation of the nondipole light-matter interaction consistent with relativity
(Journal article; Peer reviewed, 2020)An alternative and powerful Schrödinger-like equation for describing beyond dipole laser-matter interactions and leading relativistic corrections is derived. It is shown that this particular formulation is numerically very ... -
The science case for the EISCAT_3D radar
(Peer reviewed; Journal article, 2015-07-29)The EISCAT (European Incoherent SCATer) Scientific Association has provided versatile incoherent scatter (IS) radar facilities on the mainland of northern Scandinavia (the EISCAT UHF and VHF radar systems) and on Svalbard ... -
Scintillation and irregularities from the nightside part of a Sun-aligned polar cap arc
(Peer reviewed; Journal article, 2016-06-18)In this paper we study the presence of irregularities and scintillation in relation to the nightside part of a long-lived, Sun-aligned transpolar arc on 15 January 2015. The arc was observed in DMSP UV and particle data ... -
Scintillation and loss of signal lock from poleward moving auroral forms in the cusp ionosphere
(Journal article, 2015-10-27)We present two examples from the cusp ionosphere over Svalbard, where poleward moving auroral forms (PMAFs) are causing significant phase scintillation in signals from navigation satellites. The data were obtained using a ... -
Search for a common baryon source in high-multiplicity pp collisions at the LHC
(Journal article; Peer reviewed, 2020)We report on the measurement of the size of the particle-emitting source from two-baryon correlations with ALICE in high-multiplicity pp collisions at √s = 13 TeV. The source radius is studied with low relative momentum ... -
Search for a dark leptophilic scalar in e+e- collisions
(Journal article; Peer reviewed, 2020-10-28)Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars with masses in ... -
