Abstract

fetched live from OpenAlex

Despite great advances in forensic sciences in the last decades, our knowledge of the pathophysiology of ligature strangulation is still largely based on old writings from the 19th and beginning of the 20th century. The study of filmed hangings by the Working Group on Human Asphyxia has contributed to a better understanding of the agonal responses to strangulation by hanging, and judo-related studies have given some insight into the pathophysiology of manual strangulation, but the pathophysiology of ligature strangulation has remained largely unexplored so far. Three nonlethal strangulations filmed by an autoerotic practitioner are here presented. In these 3 ligature strangulations, the 35-year-old man is sitting on a chair. A pair of pajama pants is rolled once around his neck, with the extremities of the pants falling down on each side of his chest. The man is pulling the extremities of the pants with both hands to apply compression on his neck. After losing consciousness, he ceases to pull on the ligature, and the pants slowly loosen around the neck. A few seconds later, he regains consciousness and gets up from the chair. In the 3 nonlethal ligature strangulations presented in this study, the loss of consciousness occurred in 11 seconds. The loss of consciousness was closely followed by the onset of convulsions (7-11 seconds). These results are compared with the early agonal responses documented in filmed hangings and judo studies.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
