Abstract

fetched live from OpenAlex

Equilibrium experimental data for methane, ethane, and propane incipient hydrate formation in the presence of diethylene glycol and that for propane in the presence of ethylene glycol were obtained. Forty-six experiments were performed in the temperature and pressure ranges (264 to 283) K and (0.181 to 4.5) MPa, respectively, using the pressure search method. The experimental data were compared with predictions made using a hydrate equilibrium calculation method. The average deviation between the experimental data and calculated values was found to be 4.91%.

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.

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.
