Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Impact of acetylsalicylic acid on perioperative bleeding complications in deceased donor kidney transplantation.

Purpose: The objective of this study was to evaluate the perioperative outcomes and complications associated with the use of acetylsalicylic acid (ASA) in deceased donor kidney transplantation (KTX), with a particular focus on bleeding events.

Methods: We retrospectively analyzed 157 kidney transplant recipients (KTRs) who underwent KTX at Charité Berlin, Department for Urology, between February 2014 and December 2017. Patients were divided into two groups: patients with ASA in their preoperative medication (Group A, n = 59) and patients without ASA use (Group B, n = 98).

(Mis)estimation of the modal number of desired sexual partners.

Misperceptions of the social world can lead to actions and social policy that are detrimental to an individual's or group's well-being. Here we investigate whether misperceptions arise when participants make predictions of the modal number of ideal future sexual partners reported by heterosexual cohorts (younger cohort: 18-23 years; older cohort: 24-29 years). For both men and women and in both cohorts, the modal number of reported partners equaled 1.

Between scents and sterols: Cyclization of labdane-related diterpenes as model systems for enzymatic control of carbocation cascades.

The citrus scent arises from the volatile monoterpene limonene, whose cyclic nature can be viewed as a miniaturized form of the poly-cyclic sterol triterpenoids. In particular, as these rings are all formed from poly-isoprenyl precursors via carbocation cascades. However, the relevant reactions are initiated by distinct mechanisms, either lysis/ionization of an allylic diphosphate ester bond, as in limonene synthases, or protonation of a terminal olefin or epoxide, as in lanosterol synthases.

Lower risk of revision in fixed-bearing compared to mobile-bearing total ankle arthroplasties: A register based evaluation of 1246 patients in the Netherlands.

Background: Total ankle arthroplasty (TAA) has been developed as treatment for disabling tibiotalar osteoarthritis. TAAs are divided into mobile- and fixed-bearings. The aim was to determine the incidence and trends of fixed- and mobile bearings over time and investigate the association of bearing type and risk of revision after primary TAA in the Netherlands.
