A search is presented for production of dark-matter particles recoiling against a leptonically decaying Z boson in 20.3 fb(-1) of pp collisions at root s = 8 TeV with the ATLAS detector at the Large Hadron Collider. Events with large missing transverse momentum and two oppositely charged electrons or muons consistent with the decay of a Z boson are analyzed. No excess above the Standard Model pred
It is debated whether cancer patients treated with chemotherapy can mount an adequate response to vaccination. Material and methods. Ninety-six adult outpatients with cancer, who were undergoing chemotherapy and/or monoclonal antibody, tyrosine kinase inhibitor, irradiation or corticosteroid treatments, were studied. Two doses of the pandemic influenza A(H1N1)/09 AS03-adjuvanted split virion vacci
Bakgrund: I kampsporten brottning utsätts knäledens strukturer för stora inre och yttre kraf-ter i pressade lägen, vilket innebär att knäna tillhör de delar på kroppen som brottare skadar oftast. Tidigare studier har visat att knäskada med efterföljande operation var en vanlig anled-ning till att collegebrottare i USA tvingades avbryta sina brottarkarriärer. Nästan samtliga brottningsstudier som h
The estimated number of children who are utilised as child soldiers all over the world is 250,000 today. Based on the Coalition to Stop the Use of Child Soldiers research children were used in armed conflicts in 20 countries from 2004-2007. One of the most prominent nations involving the use of child soldiers is the Democratic Republic of the Congo. It is estimated, that 40% of them are girls, who
Bolagsordningar och aktieägaravtal skapar en hel del rättsfrågor, både individuellt och ihop. Många problem rör rättshandlingarnas rättsverkningar och vad verkningarna innebär för aktieägarna, bolaget och övriga avtalsparter. Dessa rättsfrågor har utretts i denna text och särskild hänsyn tagits till hur skydd för svagare part formar och påverkar rättsverkningarna för bolagsordningen och aktieägaraArticles of association and shareholders’ agreements create many legal issues both individually and together. Many of the problems revolve around the legal effects of the acts; what the effects entail for the shareholders, the company and other contractors. These questions have been examined in this text and special regards have been given to how protection for weaker parts form and affect the leg
A search is performed for localized excesses in the low-mass dijet invariant mass distribution, targeting a hypothetical new particle decaying into two jets and produced in association with either a high transverse momentum photon or a jet. The search uses the full Run 2 data sample from LHC proton-proton collisions collected by the ATLAS experiment at a center-of-mass energy of 13 TeV during 2015
Background: The spread of tau pathology closely correlates with the disease course and cognitive decline in Alzheimer’s disease (AD). Tau-targeting immunotherapies are being developed to stop the spread of tau pathology and thus halt disease progression. In this post hoc analysis of the ADAMANT clinical trial, we examined the performance of AADvac1, an active immunotherapy targeting the microtubul
Background Most women who are high-risk human papilloma virus (hrHPV) positive in a cervical cancer screening test will spontaneously heal from their infection. Visual inspection with acetic acid (VIA) is recommended by the World Health Organization as a triage test for cervical screening, however its accuracy as a triage test has been questioned. In this study, we aimed to examine the sensitivity
Results of a search for new phenomena in events with an energetic photon and large missing transverse momentum with the ATLAS experiment at the Large Hadron Collider are reported. The data were collected in proton-proton collisions at a centre-of-mass energy of 13 TeV and correspond to an integrated luminosity of 3.2 fb−1. The observed data are in agreement with the Standard Model expectations. Ex
A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb-1 of pp collisions at √ s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are inte
A search for supersymmetry in events with four or more charged leptons (electrons, muons and τ-leptons) is presented. The analysis uses a data sample corresponding to 139 fb−1 of proton-proton collisions delivered by the Large Hadron Collider at s = 13 TeV and recorded by the ATLAS detector. Four-lepton signal regions with up to two hadronically decaying τ-leptons are designed to target several su
Results of a search for new physics in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton-proton collision data corresponding to an integrated luminosity of 139 fb-1 at a center-of-mass energy of 13 TeV collected in the period 2015-2018 with the ATLAS detector at the Large Hadron Collider. Compared to previous publications, in addition to
A search is performed for new phenomena in events having a photon with high transverse momentum and a jet collected in 36.7fb-1 of proton–proton collisions at a centre-of-mass energy of s = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. The invariant mass distribution of the leading photon and jet is examined to look for the resonant production of new particles or the presen
Objective: A pay for performance programme was introduced in 2009 by a Swedish county with 1.6 million inhabitants. A process measure with payment linked to coding for medication reviews among the elderly was adopted. We assessed the association with inappropriate medication for five years after baseline.Design and setting: Observational study that compared medication for elderly patients enrolled
The cross-section for the production of two jets in association with a leptonically decaying Z boson (Zjj) is measured in proton–proton collisions at a centre-of-mass energy of 13 TeV, using data recorded with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 3.2 fb−1. The electroweak Zjj cross-section is extracted in a fiducial region chosen to enhance
Background: Comorbidity of bipolar disorder and obsessive-compulsive disorder is common in adolescence. Obsessive-compulsive disorder symptoms may be episodic and secondary to alterations in mood, and display specific features. Management of pediatric bipolar disorder-obsessive-compulsive disorder is challenging, as pharmacotherapy of obsessive-compulsive disorder may induce or exacerbate manic ep
A search for invisible decays of the Higgs boson as well as searches for dark matter candidates, produced together with a leptonically decaying Z boson, are presented. The analysis is performed using proton−proton collisions at a centre-of-mass energy of 13 TeV, delivered by the LHC, corresponding to an integrated luminosity of 139 fb−1 and recorded by the ATLAS experiment. Assuming Standard Model
A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of s=13 TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding
Aims/hypothesis: The aim of this study was to determine whether BMI in early childhood was affected by the COVID-19 pandemic and containment measures, and whether it was associated with the risk for islet autoimmunity. Methods: Between February 2018 and May 2023, data on BMI and islet autoimmunity were collected from 1050 children enrolled in the Primary Oral Insulin Trial, aged from 4.0 months to
