Abstract

fetched live from OpenAlex

Thermal conductivity measurements show that ice continues to amorphize for several days when kept at a fixed pressure p in the 0.79-0.88 GPa range, and fixed temperature T in the 127-130 K range. Thermal conductivity kappa decreases according to a stretched exponential in time, and its limiting long time value kappa( infinity ) varies with p and T. At 0.8 GPa and 128 K, kappa( infinity ) remains 2.5 times the value observed for high-density amorph. Consequences of these findings for our understanding of amorphization are discussed.

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.
