Abstract

fetched live from OpenAlex

The specific heat ${C}_{p}$ and thermal conductivity $\ensuremath{\kappa}$ of water's high density amorph have been measured as a function of pressure up to $1.2\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$. ${C}_{p}$ decreases on an increase in the pressure and $\ensuremath{\kappa}$ increases, both approaching a plateau value asymptotically. The decrease in ${C}_{p}$ on an increase in pressure is shown to be due to increase in the phonon frequency. The Debye temperature calculated from the available sound velocity data increases asymptotically with an increase in pressure and increases approximately linearly with an increase in the density of the amorph. The Gr\"uneisen parameter of the high density amorph is 1.3. While the Debye theory explains the variation of ${C}_{p}$ with pressure, it does not seem to do so for the variation of $\ensuremath{\kappa}$ with pressure.

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.
