Abstract

fetched live from OpenAlex

Both chronic sleep deprivation and oversleeping increase the risk of heart disease in women, a new North American study has found ( Archives of Internal Medicine 2003;163:205-9). As short term sleep deprivation has been associated with increases in cortisol and cholesterol levels, as well as causing increases in sympathetic tone and hypertension, researchers from the Harvard School of Public Health in Massachusetts and from the Department of Medicine in Vancouver, British Columbia, sought to investigate whether chronic sleep deprivation increased the risk of heart disease in women. Led by Drs Najib …

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.
