Abstract

fetched live from OpenAlex

We report on an x-ray diffraction investigation of the nucleation and growth of wax crystals and the evolution of the resulting wax-gel deposit in mixtures of paraffin wax and dodecane under pipe flow. This work is an in situ x-ray diffraction study of wax crystallization in oil-wax mixtures under flow and is completely noninvasive. This technique is shown to be consistent with other methods.

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.
