Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Background: There is increasing recognition that the interpretation of active-controlled HIV prevention trials should consider the counterfactual placebo HIV incidence rate, that is, the rate that would have been observed if the trial had included a placebo control arm. The PrEPVacc HIV vaccine and pre-exposure prophylaxis trial (NCT04066881) incorporated a pre-trial registration cohort partly for this purpose. In this article, we describe our attempts to model the counterfactual placebo HIV incidence rate from the registration cohort.

Background: Tecovirimat, an antiviral treatment for smallpox, was approved as a treatment for mpox by the European Medicines Agency in January 2022. Approval was granted under "exceptional circumstances" based on effectiveness found in pre-clinical challenge studies in animals and safety studies in humans showing minimal side effects. As clinical efficacy studies are still ongoing, there is currently limited information with regard to the acceptability of tecovirimat to treat mpox.

Background: Herpes simplex virus type 2 (HSV2) is an important cofactor for HIV acquisition and transmission. Associations between the infections are reexamined in longitudinal data from an HIV prevention trial.

Methods: The HPTN 071 (PopART) trial evaluated a combination prevention intervention in 21 urban communities in Zambia and South Africa.
