Abstract

fetched live from OpenAlex

Commentary on: van der Ploeg HP, Chey T, Korda RJ, et al . Sitting time and all-cause mortality risk in 222 497 Australian adults. Arch Intern Med 2012; 172 :494–500. Sedentary behaviour is defined by posture (sitting or lying) and low energy expenditure (<1.5 times the energy expenditure required for rest).1 The health effects of sedentary behaviour or sitting too much are not the same as the health effects of not getting enough moderate intensity physical activity. …

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.
