A search for physics beyond the Standard Model inducing periodic signals in the dielectron and diphoton invariant mass spectra is presented using 139 fb−1 of s = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. Novel search techniques based on continuous wavelet transforms are used to infer the frequency of periodic signals from the invariant mass spectra and neural network c

Argonauts of industry: Knowledge gathering and technologies in use in Sweden’s industrial breakthroughIn this article we explore how knowledge transfer about industrial production and new technologies affected Sweden’s rapid industrialisation in the second half of the nineteenth century. Focusing on two case studies taken from the Swedish glass and gunpowder industries, we argue for the importance

A search for pair production of scalar leptoquarks, each decaying into either an electron or a muon and a top quark, is presented. This is the first leptoquark search using ATLAS data to investigate top-philic cross-generational couplings that could provide explanations for recently observed anomalies in B meson decays. This analysis targets high leptoquark masses which cause the decay products of

The results of a search for direct pair production of top squarks and for dark matter in events with two opposite-charge leptons (electrons or muons), jets and missing transverse momentum are reported, using 139 fb−1 of integrated luminosity from proton-proton collisions at s = 13 TeV, collected by the ATLAS detector at the Large Hadron Collider during Run 2 (2015–2018). This search considers the

Probabilistic building performance simulations enables a method for evaluating how the data quality used to create input models affects the accuracy of the predicted energy performance. The method described in this paper explores an uncertainty analysis of a fixed building design and system by including the discrepancy between the declared property of a product, material, or behaviour quantified u

Knowledge of how to design digital systems that are ergonomically sound, high in usability, and optimized for the user, context, and task has existed for some time. Despite this, there are still too many examples of new digital health care systems that are poorly designed and that could negatively affect both the work environment of health care staff and patient safety. This could be because of a

Background. Flattening filter-free (FFF) beams are an emerging technology that has not yet been widely implemented as standard practice in radiotherapy centers. To facilitate the clinical implementation of FFF, we attempted to elucidate the difference in plan quality and treatment delivery time compared to flattening filter beams (i.e. standard, STD) for several patient groups. We hypothesize that

Breast cancer is the second most common cancer worldwide. Metastasis is the main reason for death in breast cancer, and today, there is a lack of methods to detect and isolate circulating tumor cells (CTCs), mainly due to their heterogeneity and rarity. There are some systems that are designed to detect rare epithelial cancer cells in whole blood based on the most common marker used today, the epi

BACKGROUND: Engagement in activities meaningful to the individual may support the process of recovery in those with mental illness. Persons with psychiatric disabilities may reduce their engagement in meaningful activities to various degrees with possible fluctuations over time. We hypothesized that activity engagement can be altered when opportunities and support are offered at an individual and

I uppsatsen undersöks i vilken mån som personal inom hälso- och sjukvården kan omfattas av rättsskyddet i 17 kap. 1 §§ BrB. Lagbestämmelserna anger rekvisiten för våld och hot mot tjänsteman och innebär ett utökat rättsskydd för den som uppfyller definitionen av tjänstemannabegreppet. Uppsatsen kommer därför att utreda omfattningen av rättskyddet samt vilka kriterier som ska uppfyllas för att tjän

I vår studie har vi kommit fram till att det inte finns någon entydigt och klart svar på våra frågeställningar. Vårt exempelföretag Previa visar och mäter att kundens investering ger effekt genom ett unikt kommunikationsverktyg som heter Hälsoeffekten. Verktyget fungerar så att företagets alla siffror förs in i ett system som ger en överblick av företaget. Previa kan sällan garantera att den önska

Denna uppsats syftar till att undersöka hur EU-rätten har påverkat svenska arbetstagarorganisationers möjligheter att använda sig utav stridsåtgärder och vilka effekter denna påverkan kan ha på den svenska arbetsmarknadsmodellen. För det första måste det sägas att EU-domstolens genom Laval och Viking har gjort det svårare för arbetstagarorganisationer att vidta stridsåtgärder då domstolen ansett aThis thesis has the aim of investigating how EU-law has affected the legal position regarding Swedish trade union’s possibilities of undertaking industrial actions. It also aims at determining whether the influence of EU-law on the right to undertake industrial actions has had any effects on the Swedish model. According to CJEU’s judgements in Laval and Viking it must be said that the possibilit

This paper uses an explorative case study approach to study the potential of export-led growth in the Ethiopian economy by focusing on the agribusiness sector of the economy. The paper draws on a GVC framework to analyse Ethiopian agribusiness exports and the use of the preferential trade agreement, Everything but Arms, as a potential enabler for further export growth. The aim of the paper is to s

Upphovsrätten utmanas ständigt av nya teknologiska fenomen. På senare tid har den tekniska utvecklingen möjliggjort att alster som tidigare var beroende av mänskligt skapande kan åstadkommas genom mer eller mindre automatiserade processer. I denna kategori finner vi kamerafällor som förenklat kan beskrivas som kameror som antingen ställs in för att ta fotografier konstant eller vid ett visst tidsiCopyright law is constantly challenged by new technological phenomena. Recently, new technology has enabled the making of creations through more or less autonomous processes. Some of these creations were previously dependent on human creativity for its existence. Situated in this category are camera traps. Camera traps can somewhat simplified be explained as cameras that are either set to take pic

This study aims to analyze the effects of competition on quality, efficiency, produced volume and gaming the system of specialized health care in Sweden, after implementation of the Freedom of Choice Act (LOV, Lagen om Vårdval). This is done by using data for specialized ophthalmology, which is a patient-elective diagnostic category. The motive behind the law, which established free entry for priv

This thesis aimed to discover the underlying causes for the drastic loss in support for the Sunshine Policy and the role of the Ministry of Unification throughout its duration. The Sunshine Policy was a new approach to inter-Korean relations by the progressives in South Korea which, despite initially strong support, would eventually become disfavoured among large parts of the population. An establ
