Abstract

fetched live from OpenAlex

Forensic taphonomy investigates the postmortem processes of human remains, focusing on the environmental factors that influence decomposition. Recent studies have highlighted the potential forensic relevance of fungi in this context, but the knowledge base remains limited. This study explored fungal communities associated with outdoor human decomposition at the REST[ES] facility in Quebec. Nested PCR amplification and Illumina MiSeq sequencing were used to identify fungal species on discolored patches of twelve samples of desiccated soft tissues from three donors. Twelve fungal species were putatively identified, some of which were previously unknown on human remains, including Leucosporidium yakuticum , Tausania pullulans , and Fusicolla species. These fungi may contribute to tissue discoloration and following longitudinal investigation, could serve as biomarkers for forensic reconstructions, including place and time of death. This study emphasizes the need for further research into the role of fungi in human decomposition processes and their applications in forensic science. • We identified the first fungal species associated with human decomposition in Quebec. • Twelve fungal species were identified, some previously unknown on human remains. • The molecular identification of fungi avoided bias toward only culturable species.

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.
