Abstract

fetched live from OpenAlex

Interdependence of the configurational, vibrational, and anharmonic-force contributions to the entropy of a liquid during its supercooling is investigated, and the effect of the anharmonic-force contribution to the entropy at constant pressure and constant volume conditions is analyzed. For realistic values of the Grüneisen parameter and expansion coefficient of a liquid, this contribution is found to be 30–40% of the heat capacity, which is high enough to affect the relation between the viscosity and excess entropy. An analysis of the resolved contributions to entropy of liquid selenium, an N-type liquid, shows that its configurational entropy is not proportional to its excess entropy.

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.
