Search results

A search is presented for new particles produced in proton-proton collisions at a centre-of-mass energy of 13 TeV that result in final states comprising a massive vector (W or Z) boson that decays hadronically and large missing transverse momentum. The data sample was collected with the ATLAS experiment at the Large Hadron Collider from 2015 to 2018 and corresponds to an integrated luminosity of 1

This paper presents a search for supersymmetric particles in models with highly compressed mass spectra, in events consistent with being produced through vector boson fusion. The search uses 140 fb−1 of proton-proton collision data at s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Events containing at least two jets with a large gap in pseudorapidity, large missing tran

The online information landscape is a site for contested ideas, but it is also a marketplace; under the platform economy, every engagement has monetary value. This setup encourages content creators to circulate the kinds of material most likely to capture attention, even if it is incendiary. Central to this business model are the algorithmic recommendation systems, which are designed to monetize a

The ATLAS tile calorimeter (TileCal) is the hadronic sampling calorimeter covering the central region of the ATLAS detector at the Large Hadron Collider (LHC). This paper gives an overview of the calorimeter’s operation and performance during the years 2015–2018 (Run 2). In this period, ATLAS collected proton–proton collision data at a centre-of-mass energy of 13 TeV and the TileCal was 99.65% eff

This master thesis investigates possibilities to use additive manufacturing in the form of Fused Fil- ament Fabrication (FFF) with the material Polylactic Acid, to replace polyurethane foams for less environmental impact. The mechanical properties of foam are difficult to mimic and there are few or no materials that are similar, hence the great challenge to replace it. The idea of using a flexible

Maskin- och monteringshallen i Varvsstaden i Malmö är en del av det tidigare Kockums-området, som under 1900-talet var en av stadens viktigaste industrimiljöer. Här byggdes fartyg som exporterades över hela världen, och området kom att spela en central roll i Malmös industriella utveckling. Hallen uppfördes 1912 och är idag ett kulturhistoriskt värdefullt industriminne som bevaras inom ramen för oThe Machine and Assembly Hall in Varvsstaden (Malmö, Sweden) is a heritage industrial building currently being refurbished into office space. As part of the renovation, the historic cast-iron framed windows will be complemented by an inner insulating window installed approximately 500 mm inside the existing line, creating an air cavity and altering the mechanical loading conditions of the original

Abstract Invasive species often have harmful effects on human activities and biodiversity. The Tapinoma nigerrimum complex includes three species that exhibit invasive traits and the ability to form supercolonies, including Tapinoma magnum and Tapinoma darioi . While these species are native to the Mediterranean basin, they have recently been reported as invasive in more northern regions of Europe

1. Grassland is an important habitat for butterflies and many other pollinating insects. Over half of the 501 European butterflies use grasslands as one of their main habitats.2. The Grassland Butterfly Index has been adopted by the EU as a key measure of progress towards the target of halting biodiversity loss, restoring nature in agro-ecosystems and reversing the decline in pollinators by 2030, 1.

Cetaceans are negatively affected by anthropogenic activities, including acoustic and physical disturbance from boat traffic. Behavioural responses to such disturbances are context-dependent, and site-specific insights are needed for effective local management plans. In this study, the impact of speed and proximity of recreational boats on the swimming speed and surfacing interval of one of the mo

This dissertation examines the intense presence of the encounter with a number of artworks depicting sickrooms painted by Nordic artists by the end of the nineteenth century. To understand the intense presence enhanced through the encounter with these artworks, this dissertation argues that these paintings can be understood and examined as secular devotional images. Particular attention is devoted

A search for the production of a Higgs boson and one or more charm quarks, in which the Higgs boson decays into a photon pair, is presented. This search uses proton-proton collision data with a centre-of-mass energy of s = 13 TeV and an integrated luminosity of 140 fb−1 recorded by the ATLAS detector at the Large Hadron Collider. The analysis relies on the identification of charm-quark-containing

AimTo explore the meaning of lived experiences of women with a hereditary risk of breast cancer who participate in surveillance of their breasts with magnetic resonance imaging.DesignHermeneutic phenomenology.MethodsInterviews on two occasions were made with 14 women in the surveillance programme. The verbatim transcripts were analysed according to van Manen. The analysis was an insightful iterati

OBJECTIVE: Tumor deposits (TDs) are a negative prognostic factor in colorectal cancer, independent of lymph node metastasis (LNM). This study aimed to investigate the ability of pre-operative MRI to identify TDs and differentiate them from LNM in rectal cancer.MATERIALS AND METHODS: Patients with histopathological N1-N2 rectal cancer with and without TDs who underwent curative-intent primary surge

Monoclonal gammopathy of undetermined significance (MGUS) is a necessary precursor condition to multiple myeloma (MM). Given the role of autophagy in modulating MM risk, we investigated whether genetic variation in autophagy-related genes influences susceptibility to MGUS. We analyzed the association of 34,042 common autophagy-related single nucleotide polymorphisms (SNPs) with MGUS across six ind

INTRODUCTION: The immune microenvironment plays a crucial role in the progression of colorectal cancer (CRC), but its variation across primary tumors and metastatic sites remains incompletely understood. In this study, we compared the composition and prognostic significance of the immune microenvironment in lung metastases, paired primary tumors, and liver metastases from a retrospective cohort of

Despite rapid clinical translation, induced pluripotent stem cell (iPSC)-derived therapies face limited global adoption. Harmonized quality control (QC) remains absent, with even fundamental parameters evaluated inconsistently across laboratories. To address this, we conducted two international Quality Assessment Rounds (QARs): QAR 2019 (18 sites, 11 countries) and QAR 2023 (23 sites, 12 countries

A search for heavy pseudo-scalar (A) and scalar (H) Higgs bosons decaying into a top-quark pair (tt¯) has been performed with 140 fb−1 of proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a centre-of-mass energy of s = 13 TeV. Interference effects between the signal process and Standard Model (SM) tt¯ production are taken into account. Final states with

Dermatan sulfate epimerase 1 (DS-epi1) is a key enzyme in the biosynthesis of the glycosaminoglycan chondroitin sulfate/dermatan sulfate, catalyzing the conversion of glucuronic acid to iduronic acid at the polymer level. Chondroitin sulfate/dermatan sulfate chains are found on at least 32 proteoglycans, many of which are implicated in human diseases and syndromes, as well as in both malignant and

ObjectivesAthletes competing in blind football have consistently been highlighted as at risk for injuries, and potential concussions. This study described the incidence of injuries sustained by athletes competing in blind football (Football 5-a-side) at the London 2012, Rio 2016 and Tokyo 2020 Paralympic Games. This study described injury proportions and incidences by age, period of competition, o

Properties of the underlying-event in pp interactions are investigated primarily via the strange hadrons KS0, Λ and Λ¯, as reconstructed using the ATLAS detector at the LHC in minimum-bias pp collision data at s=13 TeV. The hadrons are reconstructed via the identification of the displaced two-particle vertices corresponding to the decay modes, Λ→π-p and Λ¯→π+p¯. These are used in the construction
