This paper presents a search for exotic decays of the Higgs boson into a pair of new pseudoscalar particles, Formula Presented, where one pseudoscalar decays into a Formula Presented-quark pair and the other decays into a Formula Presented-lepton pair, in the mass range Formula Presented. The analysis uses Formula Presented collision data at Formula Presented collected with the ATLAS detector at t
Two synchrotron-based studies on 4H-pyran-4-thione, photoelectron spectroscopy and vacuum ultraviolet (VUV) absorption spectra were performed. A highly resolved structure was observed in the photoelectron spectrum (PES), in contrast to an earlier PES study, where little structure was observed. The sequence of ionic states was determined using configuration interaction and coupled cluster methods.
Den här rapporten är en del av ett större utvecklingsprojekt och baseras på en serie digitala forskningscirklar för kuratorer inom hälso- och sjukvården som pågick mellan 2020 och 2022. Författarna undersöker, med hjälp av anteckningar från forskningscirklarna och egna erfarenheter som kliniskt verksamma kuratorer, hur deras arbete kan förstås både inom den egna professionen och i samverkan med an
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed using the Large Hadron Collider proton-proton collision data sample at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector that correspo
Background and purposeHYPO-RT-PC was the first phase 3 trial showing the long-term efficacy and safety of extremely hypofractionated radiotherapy schedules (ultra-hypofractionation or stereotactic body radiotherapy) compared with standard radiotherapy in localised prostate cancer. We aimed to verify their safety in the context of a clinical trial, by comparing events of potentially radiotherapy-re
OBJECTIVE: Glomerular filtration rate (GFR) is generally accepted as the best overall index of renal function. Thus, all potential live kidney donors are tested to ensure that they have a normal GFR before they are eligible for kidney transplantation. The choice of GFR test is very much dependent on local traditions and may include iohexol, 51Cr-EDTA, inulin, or creatinine clearance based on urine
Although the ~200 impact craters known on Earth represent only a small fraction of the craters originally formed, the available data suggest an excess of craters by one order of magnitude, in number, in the interval ca. 470-440 Ma during the Ordovician. Most of these “excess” craters may be related to the breakup of the L-chondrite parent body (LCPB) in the asteroid belt at 465.8 ± 0.3 Ma. This is
A search for events with one top quark and missing transverse momentum in the final state is presented. The fully hadronic decay of the top quark is explored by selecting events with a reconstructed boosted top-quark topology produced in association with large missing transverse momentum. The analysis uses 139 fb−1 of proton-proton collision data at a centre-of-mass energy of s = 13 TeV recorded d
BACKGROUND: The diagnosis of bone mineral density (BMD) abnormalities involves dual-energy x-ray absorptiometry (DXA), but few patients complete this after a fragility fracture. The assessment of BMD using Hounsfield unit (HU) measurements from computed tomography (CT) scans has been correlated with DXA results in previous studies. We aimed to evaluate the correlation between shoulder CT HU and DX
Freshwater demand is expected to rise while supplies decline, putting pressure on water systems. Water conservation and determining potential alternative sources is imperative. The thesis aims to determine the effectiveness of greywater recycling as an alternative source in Sweden. Sörsjön was used as a case study and the roles of property owners and water utilities explored. The theory of planned
Replacing fossil fuels with renewable energy sources, such as offshore wind, is crucial to mitigating climate change. The ambitious federal targets on offshore wind set by the United States’s (US) Biden Administration will, however, increasingly impact the 129 million citizens living within local communities in coastal regions. Achieving social acceptance is therefore critical to reaching the US’
Biochar, a black carbon created from agricultural waste or residues, is primary an agricultural tool to improve soil health via moisture and nutrient retention with the added benefit of sequestering carbon. As global actors search for carbon dioxide removal (CDR) methods, biochar is increasingly promoted especially in sub-Saharan Africa (SSA) where smallholder farmers are largely affected by clima
This thesis analyses how individuals stance towards climate change reduction is affected by their view on immigration as well on their education background. It is quantitative research where data from the European Social Survey round 10 is analyzed through three multiple regression analyses. What being found was that both the immigration sentiment and the level of educational achievement were of s
The issue of dignity in the context of asylum seekers and their care has been widely discussed from various perspectives. As the rate of asylum-seeking increases, so too does the politics surrounding bare minimum standards. In the process of seeking asylum, individuals are increasingly forced to trade-off access to other rights. This study investigates the normative and human rights gaps in asylum
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
Background and purpose: Patients with focal cartilage lesions experience functional impairment. Results for biological treatments in the middle-aged patient is poor. Previous studies with focal prosthetic inlay resurfacing have shown a higher risk of conversion to total knee replacement at mid-term follow-up. A novel customized implant (Episealer, Episurf, Stockholm, Sweden) has been proposed to i
A search for pair production of bottom squarks in events with hadronically decaying τ-leptons, b-tagged jets, and large missing transverse momentum is presented. The analyzed dataset is based on proton-proton collisions at √s=13 TeV delivered by the Large Hadron Collider and recorded by the ATLAS detector from 2015 to 2018, and corresponds to an integrated luminosity of 139 fb−1. The observed da
