The PHENIX experiment at the Relativistic Heavy Ion Collider has measured omega meson production via leptonic and hadronic decay channels in p + p, d + Au, Cu+ Cu, and Au + Au collisions at root s(NN) = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu Cu and Au + Au collisions show that. p
The increasing share of weather-dependent renewable energy in the European electricity system, as a consequence of the European Union’s climate ambitions, has led to increased spot price volatility, negatively affecting consumers due to unpredictability. This case study assesses how flexibility (including power-heat cross vector flexibility) in residential buildings can affect annual costs, emissi
This thesis investigates the strategic use of fear speech, political communication designed to evoke fear by presenting threats, by Swedish political parties and lead candidates during the 2024 European Parliament election campaign on Facebook. Departing from audience-focused studies, the analysis centres on political actors’ intent, examining who employs fear speech, how frequently, and on which
Resource allocation in clouds is mostly done assuming hard requirements, applications either receive the requested resources or fail. Given the dynamic nature of workloads, guaranteeing on-demand allocations requires large spare capacity. Hence, one cannot have a system that is both reliable and efficient. To solve this issue, we introduce Service Level (SL) awareness in clouds, assuming applicati
Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. In recent studies, there has been a specific focus on how ectomycorrhizal (ECM) fungi influence carbon dynamics in boreal forests, particularly through their nitrogen acquisition. A major pa
Denna studie syftar till att undersöka hur cancelleringsprocesser ser ut i samband med skandaler för influencers och hur de utvecklas under tidens gång. Detta görs i form av en fallstudie, närmre specifikt skandalfallet med Margaux Dietz som inträffade år 2022. För att kunna dra vetenskapliga slutsatser baserat på empiri som följer narrativet, tar rapporten fäste i två teoretiska utgångspunkter - This study aims to investigate the dynamics of cancellation processes in relation to scandals involving influencers and how they evolve over time. It is conducted through a case study, specifically focusing on the scandal involving Margaux Dietz that occurred in 2022. In order to draw scientific conclusions based on empirical evidence that aligns with the narrative, the report adopts two theoretic
The increasing traffic on both railways and roads increases the risk of accidental collision with bridges and buildings. One way to prevent disproportionate collapse of structures if an unforeseen accident occurs is to make the structure robust. A structure that is robust has the ability to withstand progressive collapse initiated by local failures. The aim of this Master thesis is to study the te
Bakgrund: I en tid med hårdnande konkurrens, där utbudet ofta är större än efterfrågan, tvingas organisationer till effektivisering. Därav har vikten av att implementera ett starkt varumärke ökat, via denna kan kunden upplysas om produkt, kvalitet samt funktion. Efter den svenska skolreformen infördes, vilket innebar att skolväsendet öppnade upp sina portar för konkurrens, har betydelsen av varumä
In I-123-IBZM brainSPECT, the main interest is the activity uptake in the striatum relative to the background, and semi-quantitative techniques using regions of interest are typically used for this purpose. Uncertainties in the measured uptakes can however be a problem due to low contrasts and high noise levels. Like SPECT in general, IBZM SPECT should benefit from reconstruction methods that incl
BACKGROUND: The amount of myocardium at risk (MaR) during acute coronary occlusion and the duration of occlusion are important determinants of final infarct size. The main goal of early reperfusion therapy is to salvage ischemic myocardium, thereby preserving left ventricular function. The aims of the present study were to test the feasibility of developing polar plot representations of MaR, for p
Measurements of transverse-single-spin asymmetries (A(N)) in p + p collisions at root s = 62.4 and 200 GeV with the PHENIX detector at the Relativistic Heavy Ion Collider are presented. At midrapidity, A(N) is measured for neutral pion and eta mesons reconstructed from diphoton decay, and, at forward rapidities, neutral pions are measured using both diphotons and electromagnetic clusters. The neut
The Medical Patients with Enoxaparin (MEDENOX) trial was a randomized, placebo-controlled study that defined the risk of venous thromboembolism (VTE) in acutely ill, immobilized, general medical patients and the efficacy of the low-molecular-weight heparin, enoxaparin, in preventing thrombosis. We performed a post-hoc analysis to evaluate the effect of 40 mg enoxaparin once daily on MEDENOX patien
OBJECTIVES: Our goal was to validate myocardium at risk on T2-weighted short tau inversion recovery (T2-STIR) cardiac magnetic resonance (CMR) over time, compared with that seen with perfusion single-photon emission computed tomography (SPECT) in patients with ST-segment elevation myocardial infarction, and to assess the amount of salvaged myocardium after 1 week. BACKGROUND: To assess reperfusion
We present azimuthal angle correlations of intermediate transverse momentum (1-4 GeV/c) hadrons from dijets in Cu+Cu and Au+Au collisions at root s(NN)=62.4 and 200 GeV. The away-side dijet induced azimuthal correlation is broadened, non-Gaussian, and peaked away from Delta phi=pi in central and semicentral collisions in all the systems. The broadening and peak location are found to depend upon th
