Abstract

fetched live from OpenAlex

Two separate cases of death due to suicidal formaldehyde poisoning are reported. Formaldehyde is very rapidly metabolized to formic acid (formate). Formate concentrations were as follows: Case 1—blood 0.37, vitreous humor 0.12, urine 0.08; Case 2—blood 0.72, vitreous humor 0.57, urine 0.41 (all g/L). Methanol was also detected in all specimens, attributed to its presence as a stabilizer in commercial formaldehyde solutions. Formate was measured by headspace gas chromatography on an Rtx-BAC1 fused silica column (30 m × 0.53 mm ID, 3.0 μm film thickness, Restek #18001) after in situ methylation using methanol and concentrated sulfuric acid. The internal standard was diisopropyl ether.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
