Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

fundA Canadian funder is recorded on the work.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

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.

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.
