This Letter presents a search for the production of a long-lived neutral particle (Zd) decaying within the ATLAS hadronic calorimeter, in association with a standard model (SM) Z boson produced via an intermediate scalar boson, where Z→+ (=e, μ). The data used were collected by the ATLAS detector during 2015 and 2016 pp collisions with a center-of-mass energy of s=13 TeV at the Large Hadron Collid

From 2013 onward, Sweden and Finland gradually distinguish themselves from all other NATO partners in order to meet the growing challenge how to defend the Baltics. In the analysis, the concept of ‘informal ally’, in contrast to ‘formal ally’, is introduced. A synthesized analytical framework is used to evaluate the process of ever closer partner cooperation and its shifting focus from cooperative

Nils-Eric Sahlin och Sylvia Schwaag Serger diskuterar i kapitel tre hur forskare har interagerat med beslutsfattare under krisen och presenterar principer som syftar till att förbättra samspelet mellan vetenskap och politik.

This paper addresses the influence of deteriorating structural system characteristics on the value of structural health monitoring (SHM) before its implementation. The value of SHM is calculated within a recently developed framework utilizing the Bayesian pre-posterior decision analysis modelling the structural system performance, the integrity management, the structural risks and the SHM informat

Background: Patients with colorectal cancer were examined to determine (1) whether elevated carcinoembryonic antigen (CEA) levels, either before treatment or after surgery, was associated with an increased risk of overall or colorectal cancer-specific mortality or recurrence, and (2) whether high intensity follow-up would benefit those patients. Materials and methods: Post-hoc analysis based on 25

The goal of this work is to specify and investigate suitability of a number of selected permanent magnet synchronous machine (PMSM) topologies to be mounted directly on a low pressure shaft (LPS) of a geared turbofan engine. The starting point of the work is to explore the status of electrical machines for more electric engine in order to study different design aspects when identifying and definin

In this paper, I analyse developments in the relationship between popular musicians and their audiences that have intensified during the COVID-19 pandemic of 2020–21. The first, guilty geographies, concerns musicians and music venues becoming increasingly reliant on charitable audience support, appealing to fans’ ethical consciences through the crowdfunding (or fan-funding) model. The second, comp

A search for charged Higgs bosons decaying into W±W± or W±Z bosons is performed, involving experimental signatures with two leptons of the same charge, or three or four leptons with a variety of charge combinations, missing transverse momentum and jets. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider betwe

A search for electroweak production of supersymmetric particles is performed in two-lepton and three-lepton final states using recursive jigsaw reconstruction, a technique that assigns reconstructed objects to the most probable hemispheres of the decay trees, allowing one to construct tailored kinematic variables to separate the signal and background. The search uses data collected in 2015 and 201

Urbana, pluviala översvämningar orsakar stor skada på infrastruktur, byggnader och stadslivet under och efter extremregn. I den här studien har anmälningar och rapporter från försäkringsbolag och VA-huvudmannen i Malmö, VA Syd, analyserats spatialt. Målsättningen var att få en bättre förståelse för de mekanismer som påverkar pluviala översvämningar, dvs. översvämningar från intensiva regn, ibland Urban, pluvial flooding severely effects infrastructure, buildings and urban life during and after extreme rainfall. In this study, spatial analyses of flood claims from insurance companies and the water utility company of Malmö, VA Syd, are used to better understand the mechanisms and characteristics of pluvial flooding. The same data sets are used to analyse how blue-green infrastructure impacts

Jordens inträde i antropocen har lett till att historievetenskapens traditionella motsättningar mellan natur och kultur, samt den mänskliga historiens tid och geologisk tid har börjat ifrågasättas. Hur står sig historievetenskapens traditionella syften och metoder i förhållande till den pågående omförhandlingen mellan historiografi och naturalism?

Through a systematic review and a series of meta-analyses, we evaluated the general responsiveness of putative transcriptional biomarkers of general toxicity and chemical stress. We targeted metal exposures performed on bivalves under controlled laboratory conditions, and selected six transcripts associated with general toxicity for evaluation: catalase (cat), glutathione-S-transferase (gst), heat
