A search is presented for direct top squark pair production in final states with one isolated electron or muon, jets, and missing transverse momentum in proton-proton collisions at root s = 7 TeV. The measurement is based on 4.7 fb(-1) of data collected with the ATLAS detector at the LHC. Each top squark is assumed to decay to a top quark and the lightest supersymmetric particle (LSP). The data ar
To describe the Avodart after Radical Therapy for prostate cancer Study (ARTS), investigating the use of dutasteride (a dual 5 alpha-reductase inhibitor that suppresses intraprostatic dihydrotestosterone, reduces tumour volume and improves other markers of tumour regression in prostate cancer) to prevent or delay disease progression in patients with biochemical recurrence after therapy with curati
Most models to predict biochemical recurrence (BCR) of prostate cancer use pretreatment serum prostate-specific antigen (PSA), clinical stage and prostate biopsy Gleason grade. We investigated whether human glandular kallikrein 2 (hK2) and free prostate-specific antigen (fPSA) measured in pretreatment serum enhance prediction. We retrospectively measured total PSA (tPSA), fPSA and hK2 in preoperat
PURPOSE: The partial volume effect (PVE) is an important source of bias in brain perfusion measurements. The impact of tissue PVEs in perfusion measurements with dynamic susceptibility contrast MRI (DSC-MRI) has not yet been well established. The purpose of this study was to suggest a partial volume correction (PVC) approach for DSC-MRI and to study how PVC affects DSC-MRI perfusion results.METHOD
Background: This study explored peer-led sex education for individuals with intellectual disabilities and/or autism (ID/ASD) from the perspective of project leaders within Swedish non-governmental organizations (NGOs). The purpose of this Grounded Theory study was to develop a conceptual model that characterizes the ways in which peer-led sex education is implemented by Swedish NGOs. This was done
A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectatio
Agenda 2030 Graduate School monthly newsletter #9 2025-10-13 Ylva van Meeningen Hi! Thank you so much to all of you who participated in our PhD conference on Sustainable Development 9th of October. It was truly an inspirational day and it is always fun for us to see and hear about all the exciting research that is happening at Lund University and beyond. As the colors of the trees’ leaves change,
In England saltmarshes account for less than 0.5% of the land area, however they have a very high biodiversity value and provide significant economic and social worth. Climate change, continuous coastal urbanisation, and port development are a serious concern for coastal protection planners, city councils and the government. It is a challenge for these decision makers to balance the social, econom
Background : Currently, antiretroviral therapy (ART) is recommended for all HIV-positive patients with tuberculosis (TB). The timing of ART during the course of anti-TB treatment is based on CD4 cell counts. Access to CD4 cell testing is not universally available; this constitutes an obstacle for the provision of ART in low-income countries. Objective : To determine clinical variables associated w
A search is presented for the direct pair production of a chargino and a neutralino [Formula: see text], where the chargino decays to the lightest neutralino and the [Formula: see text] boson, [Formula: see text], while the neutralino decays to the lightest neutralino and the 125 GeV Higgs boson, [Formula: see text]. The final states considered for the search have large missing transverse momentum
Popular Abstract in Swedish I Sverige betonas idag alltmer det hälsofrämjande arbetet riktat mot barn, ungdomar och deras föräldrar. Olika föräldrastödsaktiviteter erbjuds. Det behövs ökad kunskap om varför vissa aktiviteter fungerar bättre än andra. Det är även viktigt att känna till föräldrarnas motiv för att deltaga och upplevelser av stödaktiviteten. Syftet med denna avhandling var att belysa In today's Swedish society there is increasing emphasis on health-promotive work among children, adolescents, and their parents. Knowledge is needed about why certain activities work better than others. It is important to study the parents' motives and experiences of participating in parental supporting programmes. In child health care, mostly among the nurses, there is a contrast between what th
Rå biogas är varm, mättad med vatten och innehåller små mängder av korrosiva spårämnen när den lämnar rötkammaren. I detta skick kan gasen inte levereras till uppgraderingsenheten som tar bort koldioxid, vattenånga och andra föroreningar för att leverera biometan som uppfyller fastställda kvalitetskrav. Den höga fuktigheten kombinerat med reaktiva ämnen leder till okontrollerad kondensation och koRaw biogas leaving an anaerobic digester is warm, saturated with water vapor, and contains small amounts of corrosive trace compounds. In this state, the gas cannot be fed directly to an upgrading system, where carbon dioxide, water vapor and other contaminants are removed to produce biomethane that meets a predefined quality. High humidity combined with reactive species promotes uncontrolled cond
ObjectiveWe investigate the association between the geographic proximity of the grandparents on net marital fertility and maternal survival in Sweden, 1900–1910, within the framework of the cooperative-breeding-hypothesis.MethodsData were derived from Swedish full-count censuses (1880–1910) and the Swedish Death Index. Married couples were linked to their parental households. Poisson and logistic
A search for new phenomena with top quark pairs in final states with one isolated electron or muon, multiple jets, and large missing transverse momentum is performed. Signal regions are designed to search for two-, three-, and four-body decays of the directly pair-produced supersymmetric partner of the top quark (stop). Additional signal regions are designed specifically to search for spin-0 media
A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in proton-proton collisions at the Large Hadron Collider at s=13 TeV is presented. The analysis utilizes the dominant W→qq¯′ or Z→qq¯ and H→bb¯ decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 139 fb-1 collected with the ATLAS detector is anal
This paper presents a dedicated search for exotic decays of the Higgs boson to a pair of new spin-zero particles, H→ aa, where the particle a decays to b-quarks and has a mass in the range of 20–60 GeV. The search is performed in events where the Higgs boson is produced in association with a W boson, giving rise to a signature of a lepton (electron or muon), missing transverse momentum, and multip
A search for the standard model Higgs boson produced in association with a vector boson with the decay H→ττ is presented. The data correspond to 20.3 fb-1 of integrated luminosity from proton-proton collisions at s=8 TeV recorded by the ATLAS experiment at the LHC during 2012. The data agree with the background expectation, and 95% confidence-level upper limits are placed on the cross section of t
