Abstract

fetched live from OpenAlex

Seventy-three samples of motor gasoline, collected in winter 2010 from eight provinces across Canada, and representing three different grades from 18 different refiners/retailers, were analyzed by gas chromatography-mass spectrometry. Each sample was analyzed in its unevaporated state, at four different levels of evaporation (25%, 50%, 75%, 90% by volume), and as a residue (approximately 99% evaporated). The resulting total ion chromatographic patterns and extracted ion profiles from these samples were compared and differences discussed in the context of identifying gasoline recovered from a fire scene

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.

Full frame distilled prediction

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.
