Abstract

fetched live from OpenAlex

An isochoric equilibrium cell was used for measuring the solid−vapor−liquid equilibrium conditions of semiclathrates formed in an aqueous solution of tetra- n -butylammonium bromide (TBAB). The semiclathrates were formed from two different synthetic landfill gas (LFG) mixtures of CO 2 (1) + CH 4 (2), which had mole fractions of x 1 = 0.4 and x 1 = 0.6. The experimental temperature, pressure, and mass fraction of TBAB ranged from (286 to 293) K, from (3 to 6.5) MPa, and from (0.05 to 0.20), respectively. For both of the gases used in the present study, it was found that, at a given temperature, the pressure required to form semiclathrates is significantly lower than that required for forming gas hydrates from the same gases.

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.
