Unequal access to timely care: Geographic variation in prehospital time among injured patients at risk of hemorrhagic shock

open access: yesTransfusion, EarlyView.
Abstract Background Hemorrhage remains the leading cause of preventable traumatic deaths, with many fatalities occurring before hospital arrival. Although geographic differences in prehospital time (PHT) are recognized, contemporary national estimates and their implications for resuscitation readiness are not well defined.

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Bayesian Analysis of Postoperative Complication Risk Associated With Preoperative Exposure to Fine Particulate Matter: A Single‐Center Cohort Study

open access: yesActa Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Background Air pollution, especially particle pollution, is increasingly recognized as a potential perioperative risk factor, yet modeling environmental exposures in surgical cohorts remains methodologically underdeveloped. We demonstrate a Bayesian hierarchical framework to quantify probabilistic associations between preoperative fine ...

Topological Graph Neural Networks: A Novel Approach for Geometric Deep Learning

open access: yesApplied AI Letters, Volume 7, Issue 2, June 2026.
This graphical abstract illustrates the Topological Graph Neural Network (TopGNN) architecture. It demonstrates a parallel processing approach where an input graph is simultaneously analyzed by a standard GNN Encoder to capture local node features and by Persistent Homology to extract global topological features (like cycles and voids), visualized as a

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated
