This paper presents a measurement of the production cross-section of a Z boson in association with b- or c-jets, in proton–proton collisions at s=13 TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 140 fb-1. Inclusive and differential cross-sections are measured for events containing a Z boson decaying into electrons or muons and pr

A search is presented for the pair production of heavy vectorlike quarks (VLQs) that each decay into a W boson and a light quark. This study focuses on events where one W boson decays into leptons and the other into hadrons. The search analyzed 140 fb−1 of pp collision data with pffiffi s ¼ 13 TeV, recorded by the ATLAS detector from 2015 to 2018 during run 2 of the Large Hadron Collider. The fina

Objectives: Aidarken is a region with mercury production from cinnabar and, to a lesser extent, from mercury-antimony-fluorite and waste recycling. Recent smelting emissions of elemental Hg vapour are low; however, combined with past pollution legacies, anaemia and iodine deficiency, the health effects for vulnerable populations are still possible. The study aimed to evaluate metal(loid)s status i

Jordbruket är grundläggande för livsmedelssäkerhet och försörjning på landsbygden, men sektorn står inför varaktiga hållbarhetsutmaningar. Moderna produktionssystem har ökat avkastningen men också bidragit till markförstöring, förlust av biologisk mångfald och utsläpp av växthusgaser. Denna avhandling undersöker hur jordbrukspolitiska styrmedel kan utformas för att förbättra både den ekonomiska efAgriculture is fundamental to food security and rural livelihoods, but the sector faces persistent sustainability challenges. Modern production systems have increased yields but also contributed to soil degradation, biodiversity loss, and greenhouse gas emissions. This thesis examines how agricultural policy instruments can be designed to improve the economic efficiency and environmental effective

In the late nineteenth and for much of the twentieth century, an academic career in Sweden was highly dependent on what grade a scholar’s doctoral dissertation was awarded. Unless receiving a so-called “docent grade”, basically declaring the scholar eligible for seeking the title of docent (associate professor), the prospects of maintaining an academic career were bleak.

Unless receiving a so-called “docent grade”, basically declaring the scholar eligible for seeking the title of docent (associate professor), the prospects of maintaining an academic career were bleak. Throughout the period, thi

A search for a hypothetical heavy scalar particle, X, decaying into a singlet scalar particle, S, and a Standard Model Higgs boson, H, using 140 fb−1 of proton-proton collision data at the centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the LHC is presented. The explored mass range is 300 ≤ mX ≤ 1000 GeV and 170 ≤ mS ≤ 500 GeV. The signature of this search is one or two leptons

This twentieth anniversary special issue broadens the horizons beyond the 2013 Cooperation and Conflict special issue to develop the normative power approach through a prospective on the use of normative power in addressing the planetary organic crisis. This introduction to the special issue first sets out the contribution of the normative power approach then, second, reflects on the past three de

This report reviews the published results of searches for possible additional scalar particles and exotic decays of the Higgs boson performed by the ATLAS Collaboration using up to 140 fb−1 of 13 TeV proton–proton collision data collected during Run 2 of the Large Hadron Collider. Key results are examined, and observed excesses, while never statistically compelling, are noted. Constraints are plac

This twentieth anniversary special issue broadens the horizons beyond the 2013 Cooperation and Conflict special issue to develop the normative power approach through a prospective on the use of normative power in addressing the planetary organic crisis. The special issue argues that 21st century planetary politics, characterised by truly planetary relations of causality, can be understood and addr

Collective action is a powerful tool for social change and is fundamental to women and girls’ empowerment on a societal level. Collective action towards gender equality could be understood as intentional and conscious civic behaviors focused on social transformation, questioning power relations, and promoting gender equality through collective efforts. Various instruments to measure collective act

This study examines the multidimensional conflicts arising from land commodification through second-home development in Ziarat village, Iran, addressing a critical research gap in developing rentier states. Employing grounded theory methodology with data from 75 stakeholder interviews, the research identifies conflicts at individual-individual, individual-institutional, and institutional-instituti

Comprehensive screening of the general population is the only approach capable of identifying the majority of cases with celiac disease. In 2023, the Italian Parliament enacted a law to implement nationwide screening for celiac disease and type 1 diabetes. However, critical decisions regarding the target population, optimal timing, and screening methods remain unresolved. Previous observational st

Dual-band shared-aperture Fabry-Pérot cavity (DS-FPC) antennas with single-layer partially reflective surface (PRS) are inherently limited in the achievable frequency ratio. This paper analyzes such antennas to derive the feasible range of frequency ratio and thereafter proposes a dual-band shared-aperture antenna that can fill the frequency ratio gap. The novel design integrates a short backfire

Military cultural competency involves understanding the unique needs of military and veteran (MV) populations. Research shows that culturally competent care improves health outcomes, yet little is known about civilian sexual assault centers (SACs) supporting MV clients. Many MV clients affected by military sexual trauma (MST) seek community services due to mistrust of the military system. This stu

Introduction: Gender imbalances in academia are found globally. Even though women earn the same rate of PhD degrees, the gender imbalance becomes increasingly prominent at higher academic levels. Several reasons have been proposed for these differences, including family responsibilities, disparities in the number and size of grants awarded, invitations to present at conferences, and differences in

In the scientific domain of high energy physics (HEP), the Worldwide LHC Computing Grid (WLCG) was created in order to handle the huge compute and storage needs of the experiments at Large Hadron Collider (LHC). Today WLCG combines about 1.4 million computer cores and 1.5 exabytes of storage from over 170 sites in 42 countries. What ties the sites together is the middleware installed at each site,
