Abstract

fetched live from OpenAlex

A forensic geo-gas investigation within an urban environment has identified distinct compositional and stable-isotope characteristics related to various reference sources of methane gas by using analytical techniques such as geochemical screening, stable-carbon and stable-hydrogen isotope analysis, and radioactive carbon-isotope analysis. The results of the investigation concluded that the combination of a number of geochemical indicators produced a distinctive geo-gas fingerprint for samples from similar reference sites.

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.
