Abstract

fetched live from OpenAlex

We have demonstrated the ability of the quartz crystal microbalance to successfully measure the formation and dissociation of thin films of Xe hydrate formed from ice films in the presence of Xe gas or from a cooled mixture of water vapor and Xe gas. By monitoring the uptake of mass, we have measured the formation of Xe hydrates on ice films in the temperature range 180<T<251K. Analysis of the mass uptake reveals a final sample that has 60% by weight of Xe, in good agreement with a fully hydrated sample. The formation and dissociation conditions suggest that there is a critical temperature T0∼255K beyond which thin films of Xe hydrate are not stable.

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.

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.
