Abstract
The component oxygen fluxes that constitute a single recording of corneal oxygen uptake when a polarographic oxygen sensor (POS) is placed in contact with the cornea were determined in the in vivo rabbit eye by removing the epithelium and injecting an air bubble into the anterior chamber. The relative contribution of epithelial oxygen consumption, stromal oxygen consumption and diffusion were approximately 55, 5 and 40%, respectively. It is demonstrated that differences in corneal oxygen uptake rates recorded with a POS primarily indicate differences in epithelial metabolic activity. Changes in epithelial metabolism can be determined by measuring both corneal oxygen uptake and corneal thickness. For example, if corneal thickness is constant, differences in epithelial oxygen flux (a) between two eyes of one person, or (b) before and after a procedure in the same eye, can be calculated by multiplying the difference in oxygen consumption measured with a POS by a factor of 1.8.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
