So far away: threshold copying distances for multiple-choice answers in different exam room settings.

Clinical Relevance: Paper-based multiple-choice exams are commonly used to assess students. Answer sheets for these exams have a configuration which affords a potential opportunity for cheating.

Background: A proportion of students report cheating on assessments.

Misspecification Strikes: ASTRAL can Mislead in the Presence of Hybridization, even for Non-Anomalous Scenarios.

ASTRAL is a powerful and widely used tool for species tree inference, known for its computational speed and robustness under incomplete lineage sorting. The method has often been used as an initial step in species network inference to provide a backbone tree structure upon which hybridization events are later added to such a tree via other methods. However, we show empirically and theoretically, that this methodology can yield flawed results.

Understanding Psychedelic-Assisted Psychotherapy Providers' Perspective and Insights: A Qualitative Analysis.

Background: There is increasing interest in the use of psychedelics for therapeutic and recreational use. Research has been hindered by federal prohibition, put in place in 1970. Despite the regulatory difficulty, research has rapidly expanded in the past decade.

A Case Report of Obstructive Shock from an Esophageal Bolus Leading to Left Atrial Compression.

Introduction: Obstructive shock results from reduced cardiac output due to physical blockage of blood flow, such as cardiac tamponade. Cardiac tamponade compresses cardiac chambers, particularly the left atrium, causing decreased end-diastolic volume and cardiac output. Rapid fluid accumulation within the pericardial sac is the usual cause.

Portrait of a Cerebral Killer.

: Primary amebic meningoencephalitis (PAM) caused by is a rare and devastating infection of the central nervous system, often diagnosed late, due to its rapid progression and nonspecific symptoms. We report one of the youngest documented pediatric Vietnamese cases of PAM in a 10-month-old girl from the Mekong Delta, Vietnam. The diagnosis was confirmed through multiplex real-time PCR (MPL-rPCR), microscopy, and sequencing.
