Abstract

fetched live from OpenAlex

The effect of an increase in respiratory dead space on the ventilation during exercise was studied in 4 normal subjects breathing through a mixing chamber of variable volume at one or more work loads. The resulting increases in ventilation and alveolar Pco<sub>2</sub> were dependent on the work load and the volume of added dead space. The magnitude of the changes were related to the subject’s ventilatory response to CO<sub>2</sub>, as measured at rest. The level of exercise, CO<sub>2</sub> output, or volume of dead space did not appear to have independent effects on the ventilatory response.

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.
