A search for the leptonic charge asymmetry (Acℓ) of top-quark-antiquark pair production in association with a W boson (tt¯ W) is presented. The search is performed using final states with exactly three charged light leptons (electrons or muons) and is based on s = 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider at CERN during the years 2015–2018,

Differential and double-differential distributions of kinematic variables of leptons from decays of top-quark pairs (tt¯) are measured using the full LHC Run 2 data sample collected with the ATLAS detector. The data were collected at a pp collision energy of s = 13 TeV and correspond to an integrated luminosity of 140 fb −1. The measurements use events containing an oppositely charged eμ pair and

BackgroundAchromobacter xylosoxidans is an emerging pathogen that causes airway infections in patients with cystic fibrosis. Knowledge of virulence factors and protein secretion systems in this bacterium is limited. Twin arginine translocation (Tat) is a protein secretion system that transports folded proteins across the inner cell membranes of gram-negative bacteria. Tat has been shown to be impo

Purpose: The primary objective of this research is to determine critical success factors (CSFs) that enable textile enterprises to effectively implement Kaizen, a Japanese concept of continuous development, particularly during disruptive situations. The study aims to provide insights into how Kaizen is specifically employed within the textile sector and to offer guidance for addressing future cris

Introduction: Commissioning, calibration, and quality control procedures for nuclear medicine imaging systems are typically performed using hollow containers filled with radionuclide solutions. This leads to multiple sources of uncertainty, many of which can be overcome by using traceable, sealed, long-lived surrogate sources containing a radionuclide of comparable energies and emission probabilit

Chest computed tomography (CT) imaging with the use of an artificial intelligence (AI) analysis program has been helpful for the rapid evaluation of large numbers of patients during the COVID-19 pandemic. We have previously demonstrated that adults with COVID-19 infection with high-risk obstructive sleep apnea (OSA) have poorer clinical outcomes than COVID-19 patients with low-risk OSA. In the cur

BACKGROUND: There are few data on outcomes after reintervention for persistent or recurrent primary hyperparathyroidism (PHPT). The authors hypothesized that the variation in outcomes at the hospital level after reoperation would be significant. After accounting for this variability, some patient-level clinical criteria could be identified to help inform treatment decisions in this patient populat

Luminescence dating is a widely used method in combination with sedimentological analysis for reconstructing the landscape development of the Quaternary period. In this study, quartz and K-feldspar measurements were used to evaluate the luminescence characteristics with the aim of dating the deposits. The sediments were sampled from an abandoned gravel pit in the Biely Váh valley and eight sites i

Invasive alien species are organisms that have been introduced to an area outside their natural distribution range and threatens animals, habitats or humans in the new area. The raccoon (Procyon lotor) is a mesopredator originating from North and Central America that has been introduced in Europe and Asia. Since the first European introductions of raccoons in Germany, natural dispersal and pet tra

Studien handlar om läsbarhet i samhällskunskapsböcker på gymnasienivå. Undersökningen studerar också läsbarheten i en informationstext. Läroböcker samt samhällsinformation bör ha ett språk som underlättar för läsaren att ta till sig innehållet. Det är viktigt inte minst för elever som läser svenska som andraspråk. Materialet som undersökningen baseras på utgörs av texter om Sveriges grundlagar frå

Uppsatsen analyserar huruvida papperslösa arbetare kan göra tre arbetsrättsliga rättigheter – rätt till lön, föreningsrätt och rätt till skydd från diskriminering – gällande gentemot sina arbetsgivare. Den första frågeställningen är rättsutredande: ”Omfattar rättigheterna papperslösa, och i så fall i vilken grad och på vilket sätt inverkar migrationsrättsliga regler på tillämpligheten av rättighet

The Swedish government composed in 2012 a strategy to guarantee Romanies the same possibility to participation in the Swedish society as non Romani people. In this paper I analyze the strategy through a perspective that is critical to power structures. The analysis is based on the question of how a subordinated minority is portrayed within a majority society. The purpose is to demonstrate how powe

Issue of study: Knowledge management is recognised as an essential part of company strategy, with the potential to generate significant competitive advantage. The theoretical basis of knowledge management is well developed, however the practical implementation is not well adapted with regards to construction organisations. More research with a practical perspective regarding knowledge management

Syftet med denna studie är att med tidsgeografi analysera valet av färdmedel. Med hjälp av enkät och konstruerade dagsprogram undersöker studien resvalen. Studien görs bland småbarnsföräldrar boende i Stenkällan, en villaförort i Malmös ytterområden och visar att dessa i stor utsträckning väljer bil. Vidare undersöks vilka tidsgeografiska skäl som ligger bakom det valet och hur kollektivtrafiken kThe aim with this essay is to analyze the choice of conveyance with a time­geographic perspective. Using a survey and constructed dayprogrammes, the study examins the means of transportation. The study is conducted among parents to young children in a suburb of Malmö showing that the car is the most common means of conveyance amongst this group. Futher the reasons, from a time­ geographic perspect

The present paper discusses the process of young immigrant integration from the point of view of policymakers. The focus in narrowed to application of multiculturalism in pre-primary, primary and secondary education strategies as a tool for integration. Interpretation of multiculturalism is compared in two countries – Germany and Sweden and on two levels – national and supranational. The paper is

Organizations are increasingly using communicative strategies to try influencing consumers to create a positive image around them. However, the image is an im-material concept in the mind of the consumer, which can create problems for or-ganizations since it is not possible to predict the image that will be assign to them. The study therefore intends to create an understanding of how consumers cre
