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.

Clinical Manifestations.

Background: Frontotemporal dementia (FTD) is a diverse spectrum of neurodegenerative disorders impacting the frontal and temporal lobes, primarily manifesting as behavioral and/or language issues. Accurate diagnosis is crucial for effective management, potential treatment, and care planning. While speech analysis has shown promise in detecting cognitive markers of Alzheimer's disease (AD), its exploration in FTD is limited.

Clinical Manifestations.

Background: Subjective memory concerns (SMC) may be a sensitive marker of future cognitive declines. However, there are multiple factors that can impact the predictive utility of SMC. Prior studies have demonstrated the effect of depression on SMC.

Barriers and facilitators for cardiopulmonary resuscitation discussions with people with heart failure.

Background: Care planning with people with advanced heart failure enables appropriate care, and prevents futile interventions, such as cardio-pulmonary resuscitation (CPR).

Aim: To explore what motivates clinicians to conduct, and people with heart failure and their carers, to engage in well-conducted CPR discussions.

Methods: In-depth remote interviews with i) people with heart failure and self-reported daily symptoms (≥ 3 months), ii) informal carers and, iii) clinicians recruited through social media and professional groups, team contacts and snowballing.

A new diminutive species of bohaiornithid enantiornithine (Aves: Ornithothoraces) from the Lower Cretaceous Jehol Group, northern China.

Enantiornithes are the most successful early-diverging avian clade, their fossils revealing important information regarding the structure of Cretaceous avifaunas and the parallel refinement of flight alongside the ornithuromorph lineage that includes modern birds. The most diverse recognized family of Early Cretaceous enantiornithines is the Bohaiornithidae, known from the Jehol Biota in northeastern China. Members of this clade enhance our understanding of intraclade morphological diversity and elucidate the independent evolution of this unique lineage.
