Abstract

fetched live from OpenAlex

A simple general corresponding-states principle for vapor pressure incorporated with a simple vapor-pressure equation is presented to describe within and extend beyond the range of available experimental data for 25 halomethane substances. Apparatus type, measurement method, and precision and uncertainties are listed for the experimental vapor-pressure data sets. The experimental data with the corresponding ranges have been reviewed to test the present method in representing the vapor-pressure behavior. Comparisons with available data show that the extended corresponding-states principle for vapor pressure has very good accuracies with different data sets. The substance-dependent characteristic parameters such as critical temperature, critical density, critical pressure, and acentric factor are given from reliable literature sources along with the general method. The values of the pressures, along with their first and second derivatives as function of temperature over the entire region from the triple point to the critical point, are tabulated and recommended for scientific and practical uses.

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. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
