Abstract
We have examined whether there are changes in the day-night variation in plasma cortisol in normal women during the third trimester of pregnancy. Maximum cortisol values at 07.30-10.30 h were similar at 30-31, 34-35 and 38-39 weeks of pregnancy. The daily increment in plasma cortisol (fold change) was greater, and the trough values lower at 30-31 than at 38-39 weeks. The time taken for plasma cortisol to fall to 50% of the morning maximum values was longer at 38-39 weeks than at 30-31 weeks of pregnancy. These changes in cortisol rhythms may have implications with respect to alterations in circadian patterns of maternal steroid concentrations as well as fetal biophysical functions.

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
