Abstract

fetched live from OpenAlex

In search of low-energy excitations in rigid molecular crystals, the available heat capacity, Cp, data of 85%C60–15%C70 (wt %) mixture at temperatures in the 2–30 K range have been analyzed. It is found that its Cp/T3 against T plot has an asymmetric peak centered at 4.5 K, which has the features of both the Boson peak and of the peak attributed to librations of guest molecules in clathrates. Appearance of a peak in the Cp/T3 against T plot is a characteristic of the Einstein equation for random phase atomic motions. Most of the Cp of fullerenes at T<10 K is attributed to random phase librations of C60 and C70 molecules at their crystal sites.

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.
