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.

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.

Efficacy and safety of IMI/REL were studied in critically ill adults with hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP).
Methods: In this phase III, double-blind, multinational, randomized trial (NCT03583333), adults with HABP/VABP were randomized 1:1 to receive intravenous IMI/REL (500 mg/250 mg) or piperacillin/tazobactam (PIP/TAZ; 4000 mg/500 mg) every 6 h for 7-14 days.
Visits to hospital emergency departments by patients with multimorbidity, complex chronic conditions, and frailty are becoming an increasing challenge. A territorial strategy has been developed, based on automated preselection lists, a nurse case manager with specialized experience, and a multi-level territorial referral consensus. The feasibility of this approach has been demonstrated, with 368 alerts detected, 85% of which were well-selected.
