A search for T and Y vector-like quarks produced in proton-proton collisions at a centre-of-mass energy of 13 TeV and decaying into Wb in the fully hadronic final state is presented. The search uses 139 fb−1 of data collected by the ATLAS detector at the LHC from 2015 to 2018. The final state is characterised by a hadronically decaying W boson with large Lorentz boost and a b-tagged jet, which are
Accurate, high-resolution global land use and land cover (LULC) mapping is crucial for environmental monitoring, but remains challenging when relying solely on multispectral data. Most existing global LULC mapping studies rely exclusively on multispectral observations, and even those that incorporate synthetic aperture radar (SAR) data often fail to fully exploit the information it provides. SAR p
Hydraulic balancing is key to ensure proper operation of the heating system. When the heating system is not hydraulically balanced, heat is unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage of energy. In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variabl
INTRODUCTION: Autoantibodies against insulin (IAA) are early appearing markers of autoimmunity against the pancreatic islet beta cells and predict progression to type 1 diabetes if additional islet autoantibodies also develop. It is still controversial if proinsulin rather than insulin is the primary autoantibody.METHODS: The aim of the present study was to compare the half-maximal concentration (
This thesis poses structural and behavioural competition problems in digital markets in terms of core platforms services provided by the gatekeepers under the proposed Digital Markets Act by the European Commission, where such problems are the most evident. This thesis analyses whether existing competition and more sector-specific legal tools are functional to address these problems. Traditional l
Examining the relation between Swedish households’ debt, property price and interest rates are important when forming monetary policy implications. Several studies have examined the driving factors of household debt and property price, however the results are inconclusive. This thesis differs from previous research as it includes the variable interest to income ratio, instead of debt ratio, as the
Bumblebees and other pollinators are important contributors to the ecosystem service of pollination of wild plants and crops. As in many pollinating insects, their abundance and diversity have declined in recent years, due to loss of natural habitats and fragmentation associated with urbanization and agricultural intensification. However, in urban areas, green space management beneficial to pollin
The present thesis explores the requirement of the waiting period to grant family reunification to Third Country Nationals from the perspective of human rights law. It examines how this requirement, which currently forms a significant part of immigration policies within European member states, may impact TCNs' Right to family life under the European Convention on Human Rights (ECHR) and EU
Access to water is taken for granted in water abundant countries like Sweden, but safe water supply is increasingly threatened by droughts. This thesis analyses how the Swedish water sector responded to the unprecedented drought in 2018, by analysing water security discourse through the framework “What’s the problem represented to be?”. It explores implications of the drought on water policy and h
The recent advent of 3DSG in the computer vision domain has brought powerful high-level representations of 3D environments. These representations strive to mimic human perception and facilitate the extraction of meaningful insight from visual data. This research has led to framework like Hydra, which creates a real-time, persistent spatial perception system that creates a complete 3D map of their
The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. The lignin was then c
This study analyzes the transition to mechanized forest management and the implementation of sustainable-yields forestry in Sweden during the 1950s and 1960s. The objective is to produce insights that are relevantfor policymakers working with forests and the climate transition today. The analysis focuses on how the Swedish National Association of Forest Owners’ Associations (SSR)—an association or
OBJECTIVES: To investigate hip dysplasia as a risk factor for clinically relevant and incident radiographic hip OA.METHODS: From a prospective cohort (CHECK) of 1002 middle-aged, new consulters for hip and/or knee pain, 468 hips (251 individuals) were selected based on hip pain, available lateral center edge angle (LCEA) and absence of definite radiographic hip OA (Kellgren and Lawrence [KL] grade
Background: Lung injury in COVID-19 is characterized by neutrophil invasion and the release of neutrophil extracellular traps (NETs). An aberrant NET formation may induce local inflammation and increase sputum viscosity. Inhalation of DNase I (dornase alfa) is a treatment option that degrades NETs in the airways. Previous case series have indicated positive clinical effects of inhaled dornase alfa
Controllable hydrogen generation rate of Al-Ga-based on-site hydrogen supply materials significantly impacts their practical application. In many scenarios, the hydrolysis reaction occurs at elevated temperatures, which is a factor often overlooked in its effect on reaction kinetics. This study investigates the relationship between grain size and reaction rate in Al-Ga-based alloys for hydrogen ge
The Middle Danube (Carpathian) Basin is considered to encompass some of the thickest and most complete records of aeolian dust deposition in Europe, covering the last two glacial–interglacial cycles. In this study, independent, published chronologies based on absolute dating methods were compiled for 34 loess-palaeosol sequences and modelled using Bayesian statistics. Mass accumulation rates (MARs
Chrysene-containing polymers functionalized with piperidinium- and quinuclidinium cations, respectively, are prepared by polyhydroxyalkylation and studied as anion exchange membranes (AEMs). Experimental results, supported by theoretical considerations, indicate that the chrysene units significantly enhance alkaline stability; a poly(chrysene piperidinium) AEM shows only 16% total ionic loss, comp
Cataract surgery is the most commonly performed surgery worldwide. However, there is significant variation in practice both within and among countries. The European Registry of Quality Outcomes for Cataract and Refractive Surgery was established in 2007 to address this variation and improve the quality of care. Based on registry data from more than 500,000 surgeries, the registry developed the fir
III-Nitride based LEDs based on InGaN active layers on GaN work very well for the blue and green emitting LEDs. However, the large lattice mis-match between redemitting active layers, with at least 35% indium in the active layers, and the GaN substrate still limits the efficiencies obtained to very low values. Unfortunately, the approach to use GaAs based (GaAs/AlInGaP) devices for the red fails f
