Collective behavior has been observed in high-energy heavy-ion collisions for several decades. Collectivity is driven by the high particle multiplicities that are produced in these collisions. At the CERN Large Hadron Collider (LHC), features of collectivity have also been seen in high-multiplicity proton-proton collisions that can attain particle multiplicities comparable to peripheral Pb-Pb coll

Background: The COVID-19 pandemic has brought significant mental health challenges, particularly for vulnerable populations, including non-binary gender individuals. The COMET international study aimed to investigate specific risk factors for clinical depression or distress during the pandemic, also in these special populations. Methods: Chi-square tests were used for initial screening to select o

The present paper describes case studies where the purpose was to identify two unknown ancestors: the author’s paternal grandfather [FF] and his paternal grandmother’s maternal grandfather’s father [FMMFF]. A four-step method was used: (1) The author’s and his brother’s closest atDNA matches were identified, and the genealogical relationships to these matches were searched for by a comparison with

Context. Occultations are windows of opportunity to indirectly peek into the dayside atmosphere of exoplanets. High-precision transit events provide information on the spin-orbit alignment of exoplanets around fast-rotating hosts. Aims. We aim to precisely measure the planetary radius and geometric albedo of the ultra-hot Jupiter (UHJ) KELT-20 b along with the spin-orbit alignment of the system. M

Context. Multiwavelength photometry of the secondary eclipses of extrasolar planets is able to disentangle the reflected and thermally emitted light radiated from the planetary dayside. Based on this, we can measure the planetary geometric albedo Ag, which is an indicator of the presence of clouds in the atmosphere, and the recirculation efficiency ϵ, which quantifies the energy transport within t

The purpose of the present chapter is to discuss whether psychological science today is in a state of crisis, and if so how that crisis is to be characterized. Three aspects of a possible crisis are discussed: a replicability crisis, a normativity crisis, and a validity crisis. It is argued that the present crisis goes deeper than being merely a replicability crisis. There are also signs of a norm

For accurate determination of particle masses accurate knowledge of the momentum scale of the detectors is crucial. The procedure used to calibrate the momentum scale of the LHCb spectrometer is described and illustrated using the performance obtained with an integrated luminosity of 1.6 fb−1 collected during 2016 in pp running. The procedure uses large samples of J/ → +− and B+ → J/K+ decays and

BackgroundThe literature on the relationship between anxiety and suicidal behaviors is limited and findings are mixed. This study sought to determine whether physicians noted anxiety symptoms and suicidality in their patients in the weeks and months before suicide.MethodsData were derived from a nationwide medical record review of confirmed suicides in Sweden in 2015. Individuals with at least one

The aim of the paper is to (re-)evaluate the treatment of reduplicative expressions as compound words in nearly all previous work on English. Examples of reduplicative expressions are listed, out of context, and they are labelled as compound words, without providing proper motivations as to why it makes sense to treat them as compounds, in the sense of lexical items that are formed of other lexicaThe aim of the paper is to (re-)evaluate the treatment of reduplicative expressions as compound words in nearly all previous work on English.

The identification of helium nuclei at LHCb is achieved using a method based on measurements of ionisation losses in the silicon sensors and timing measurements in the Outer Tracker drift tubes. The background from photon conversions is reduced using the RICH detectors and an isolation requirement. The method is developed using pp collision data at √s = 13 TeV recorded by the LHCb experiment in th

The production rate of Λb0 baryons relative to B0 mesons in pp collisions at a center-of-mass energy s=13 TeV is measured by the LHCb experiment. The ratio of Λb0 to B0 production cross sections shows a significant dependence on both the transverse momentum and the measured charged-particle multiplicity. At low multiplicity, the ratio measured at LHCb is consistent with the value measured in e+e-

What is striking in the twenty years since 9/11 is not only the renewed attention to religion in the Western public sphere but the forms this attention has taken. Suspicion towards Islam has intensified. Narratives in which the West and Islam are conflicting and clashing entities have become entrenched. In Europe, anti-Muslim rhetoric has reached fever-pitch in far-right movements. What has gone l
