A search is performed for a heavy particle decaying into different-flavor, dilepton pairs (eμ, eτ or μτ), using 36.1 fb-1 of proton-proton collision data at s=13 TeV collected in 2015-2016 by the ATLAS detector at the Large Hadron Collider. No excesses over the Standard Model predictions are observed. Bayesian lower limits at the 95% credibility level are placed on the mass of a Z′ boson, the mass

OBJECTIVE: High fluctuations in injury-risk during the playing season in soccer have been reported. As seasons are structured in periods with homogenous loads and intensities, we investigated injury-risk over season periods, contrarily to previous studies adopting a month-based approach.DESIGN: Cohort study; Level of evidence, 2.METHODS: Incidence-rate ratios (IRRs) for match and training injuries

BACKGROUND: While physical activity has been shown to affect psychological as well as physiological stress responses, less research has explored the effects of acute stress on athletic performance. The current study hence aimed to investigate the effect of an Acute Psychological Stress (APS) provocation on performance and plasma lactate concentration during a following 200m swim race among male el

A measurement of the rapidity and transverse momentum dependence of dijet azimuthal decorrelations is presented, using the quantity RΔφ. The quantity RΔφ specifies the fraction of the inclusive dijet events in which the azimuthal opening angle of the two jets with the highest transverse momenta is less than a given value of the parameter Δφmax. The quantity RΔφ is measured in proton-proton collisi

Direct searches for lepton flavor violation in decays of the Z boson with the ATLAS detector at the LHC are presented. Decays of the Z boson into an electron or muon and a hadronically decaying τ lepton are considered. The searches are based on a data sample of proton-proton collisions collected by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb-1 at a cen

BACKGROUND: Coronary heart disease (CHD) is a multifactorial disease with both genetic and environmental components. Smoking is the most important modifiable risk factor for CHD. Our aim was to test whether the increased CHD incidence by smoking is modified by genetic predisposition to CHD. METHODS AND RESULTS: Our study included 24 443 individuals from the MDCS (Malmö Diet and Cancer Study). A we

Since the discovery of non-coding RNAs (ncRNAs) a new area has emerged in the field of biomarkers. NcRNAs are RNA molecules of different sizes that are transcribed as independent genes or as part of protein coding genes and are not translated, therefore they do not produce proteins. They have been classified accord-ing to their size and function and include micro RNAs (miRNAs), piwiRNAs (piRNAs),

En stödjande miljö är centralt för att kunna upprätthålla ett självständigt liv och effektivt aktivitetsutförande, särskilt med ökande ålder. För personer med funktionella begränsningar, som konsekvenserna av en ryggmärgsskada, är balansen mellan personens funktionella kapacitet och miljöns krav av yttersta vikt för att kunna leva ett så välfungerande liv som möjligt. Livslängden efter en ryggmärg

A reduced kinetic mechanism for methanol combustion at spark-ignition (SI) engine conditions is presented. The mechanism consists of 18 species and 55 irreversible reactions, small enough to be suitable for large eddy simulations (LES). The mechanism was reduced and optimized using the comprehensive mechanism (AramcoMech 2.0) as a starting point, to maintain performance at stoichiometric condition

Assessing risks and vulnerabilities in the multifaceted context of a municipality is challenging. There is a plethora of methods and tools to support this task. However, to achieve successful outcomes from Risk and Vulnerability Assessments (RVAs), merely applying theoretically and technically rigorous methods is far from enough; the question of how a method is implemented in a practical context i

A search for electroweak production of supersymmetric particles is performed in two-lepton and three-lepton final states using recursive jigsaw reconstruction, a technique that assigns reconstructed objects to the most probable hemispheres of the decay trees, allowing one to construct tailored kinematic variables to separate the signal and background. The search uses data collected in 2015 and 201

The Fiat-Shamir paradigm encompasses many different ways of turning a given identification scheme into a signature scheme. Security proofs pertain sometimes to one variant, sometimes to another. We systematically study three variants that we call the challenge (signature is challenge and response), commit (signature is commitment and response), and transcript (signature is challenge, commitment an
