A study of Λ and ¯Λ polarization splitting by meson field in PICR hydrodynamic model
(Journal article; Peer reviewed, 2021)With the PICR hydrodynamic model, we study the polarization splitting between Λ and Λ¯ at RHIC BES energy range, based on the meson field mechanism. Our results fit to the experimental data fairly well. Besides, two ... -
Study on viability of Gain Stabilization of SiPMs and determination of b-quark fragmentation fraction ratio f_c/f_u in pp collisions at √s = 13 TeV with the ATLAS detector
(Master thesis, 2017-09-05)Gain Stabilization of SiPMs through the usage of an external board to regulate bias voltage based on temperature yields a variation in gain of less than 0.5 % using a system of four SiPMs with temperature readout in close ... -
Sub-resolution contrast in neutral helium microscopy through facet scattering for quantitative imaging of nanoscale topographies on macroscopic surfaces
(Journal article; Peer reviewed, 2023)Nanoscale thin film coatings and surface treatments are ubiquitous across industry, science, and engineering; imbuing specific functional or mechanical properties (such as corrosion resistance, lubricity, catalytic activity ... -
Substantial Sparing of Organs at Risk with Modern Proton Therapy in Lung Cancer, but Altered Breathing Patterns Can Jeopardize Target Coverage
(Journal article; Peer reviewed, 2022-03-08)Enhancing treatment of locally advanced non-small cell lung cancer (LA-NSCLC) by using pencil beam scanning proton therapy (PBS-PT) is attractive, but little knowledge exists on the effects of uncertainties occurring between ... -
Substorm Current Wedge: Energy Conversion and Current Diversion
(Journal article; Peer reviewed, 2020)Using a magnetohydrodynamic simulation of magnetotail reconnection, flow bursts, and dipolarization, we further investigate the current diversion and energy flow and conversion associated with the substorm current wedge ... -
Substorm Impact on Dayside Ionospheric Currents
(Journal article; Peer reviewed, 2023)Ionospheric dayside dynamics is strongly controlled by the interaction between the Interplanetary Magnetic Field (IMF) and the Earth's magnetic field near the dayside magnetopause, while nightside ionospheric dynamics ... -
Substorm Onset Latitude and the Steadiness of Magnetospheric Convection
(Peer reviewed; Journal article, 2019-03-10)We study the role of substorms and steady magnetospheric convection (SMC) in magnetic flux transport in the magnetosphere, using observations of field‐aligned currents by the Active Magnetosphere and Planetary Electrodynamics ... -
Supersymmetric Cascade Decays at the LHC

Supersymmetric proton decay revisited
(Journal article; Peer reviewed, 2020)Encouraged by the advent of a new generation of underground detectors – JUNO, DUNE and Hyper-Kamiokande – that are projected to improve significantly on the present sensitivities to various baryon decay modes, we revisit ... -
Supersymmetry with Trilinear R-Parity Violation – Implications for Cosmology and the LHC
(Doctoral thesis, 2011-12-16)The current Standard Model of particle physics is sometimes referred to as one of the most successful theories ever constructed. When looking at the precision with which its predictions are being confirmed, it is easy to ... -
Suppression of \(\Upsilon\)(1S) at forward rapidity in Pb-Pb collisions at \(\sqrt{s_{\rm NN}}\) = 2.76 TeV
(Peer reviewed; Journal article, 2014-11-10)We report on the measurement of the inclusive \(\Upsilon\).1S) production in Pb-Pb collisions at \(\sqrt{s_{\rm NN}}=2.76\) TeV carried out at forward rapidity \(2.5<y<4\) and down to zero transverse momentum using its ... -
Suppression of high transverse momentum D mesons in central Pb--Pb collisions at \(\sqrt{s_{NN}}=2.76\) TeV
(Peer reviewed; Journal article, 2012-09)The production of the prompt charm mesons \(D^0\), \(D^+\), \(D^{*+}\), and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at the LHC, at a centre-of-mass energy \(\sqrt{s_{NN}}=2.76\) TeV ... -
Suppression of Λ(1520) resonance production in central Pb-Pb collisions at √sNN=2.76 TeV
(Peer reviewed; Journal article, 2019-02)The production yield of the Λ (1520) baryon resonance is measured at midrapidity in Pb-Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the Large Hadron Collider (LHC). The measurement is performed in the Λ ... -

Suprathermal Fe in the Earth's Plasma Environment: Cluster RAPID Observations
(Journal article; Peer reviewed, 2020)Baryonic matter in geospace is almost exclusively in a plasma state, with protons (H +) and to some extent ionized helium (He) and oxygen (O) being the dominant ion species. But also other heavier ion species and even ... -
Surface Chemistry Study of Low Salinity Waterflood
(Master thesis, 2013-06-03)There is increasing evidence that injecting low salinity brines has a significant impact on the amount of oil recovered, but the exact mechanism by which this occurs is an unsettled issue, and is supposed to be a cause 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 ... -
