Abstract
While prenatal environmental tobacco smoke (ETS) exposure has been shown to be a major cause of sudden infant death syndrome, the effects of postnatal ETS exposure have been less studied. The objective of this study is to explore the effects of 15-days postnatal exposure to 20 cigarettes/day on heart rate variability (HRV), respiratory rate variability (RRV) and cardiorespiratory interrelations in newborn lambs. On postnatal day 16, sixhours polysomnographic recording was obtained from six control lambs exposed to room air (group C0) and six lambs exposed to 20 cigarettes/day (group C20) for the first 15 days of life. ECG and respiratory movements (RSP) were continuously monitored. Several analyses were performed on these signals, including heart rate variability analyses (on the RR intervals extracted from the ECG), respiratory rate variability analyses (on different time series extracted from the breathing signal) and cardiorespiratory interrelations analyses (on both the RR interval and the breathing signal). The results suggest that ETS exposure for the first 15 postnatal days leads to slight alterations of cardiorespiratory control, which predominate on respiration.

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
