Abstract

fetched live from OpenAlex

Abstract The solubility of sulphur dioxide in mixed polyethylene glycol dimethyl ethers was determined at 25°C, 40°C, 70°C and 100°C. The results were best correlated with the NRTL activity coefficient model. Henry's law constants were obtained from the data and the excess enthalpy of the liquid mixture over the full range of composition was predicted at each temperature. In addition, the enthalpy of mixing and the enthalpy of solution were both determined at infinite dilution. The effect of water on the solubility of sulphur dioxide was also investigated with a 6.04 mass% water solution.

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.
