Given shifts to dimensional models of personality pathology and a growing consensus that personality disorder (PD) often onsets during adolescence, there is a need for validated measures of PD in adolescents.

However, no studies as of yet have validated a measure of LPF in a sample of Spanish-speaking adolescents.

Concerned about declining managed honeybee populations in North America, this study employed the random survival forest (RSF) model to assess beehive mortality, considering 18 diverse environmental, weather, and management practices. Our analysis focused on 15,906 and 6,690 beehives in California state, United States, and Quebec province, Canada for 2023, respectively. The accuracy of the RSF model was assessed through three accuracy metrics, namely concordance index (C-index), integrated Brier score (IBS), and time-dependent area under the curve (AUC).

The study of human body shape using classical anthropometric techniques is often problematic due to several error sources. Instead, 3D models and representations provide more accurate registrations, which are stable across acquisitions, and enable more precise, systematic, and fast measuring capabilities. Thus, the same person can be scanned several times and precise differential measurements can be established in an accurate manner.

A tension pneumothorax can evolve from a simple pneumothorax if there is a continued air leak from the lung without mechanism for egress.
