Abstract

fetched live from OpenAlex

38 healthy male volunteers were administered a graded exercise test during which selected respiratory gas exchange variables were monitored. In each case, two distinct ventilatory thresholds were observed. The first threshold was detected by the power output at which the V<sub>E</sub>/VO<sub>2</sub> ratio and FEO<sub>2</sub> reached a minimum. The mathematical relationship between these two variables was such that at power outputs above this threshold, hyperventilation with respect to oxygen consumption had to occur. The second threshold was detected by the power output at which the V<sub>E</sub>/VCO<sub>2</sub> ratio reached a minimum and the F<sub>E</sub>CO<sub>2</sub> reached a maximum. These two variables were related in a manner such that at power outputs above this threshold, hyperventilation with respect to carbon dioxide production had to occur.

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.
