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.

Exploratory interviews with Australian clinical research staff on how they communicate with participants.

Background: The connection between participants and their research team can affect how safe, informed, and respected a participant feels, and their willingness to complete a research project. Communication between researchers and participants is key to developing this connection, but there is little published work evaluating how communication during clinical research is conducted.

Purpose: This paper explores what communications happen (and how) with research participants in Australia post consenting to participate in clinical research.

Staff and Providers' Perceptions of Patients' PrEP Candidacy, Acceptability, and Adherence in Methadone Clinic Settings.

Background: People who use drugs and patients in substance use treatment may be placed at high risk for HIV due to mixing sex and drugs, potential engagement in sex work, and injection drug use. However, pre-exposure prophylaxis (PrEP) adoption among these populations remains low. Methadone clinics, a main point of contact with the healthcare system for this population, are a missed opportunity to offer biomedical HIV prevention.
