Abstract
This paper presents the experimental data of densities and viscosities for aqueous 2-(methylamino)ethanol solutions at six temperatures in the range (298.15 to 343.15) K and refractive indices at seven temperatures in the range (293.15 to 323.15) K. Excess molar volumes, viscosity deviations, and molar refraction changes were calculated from the experimental results and correlated as a function of the mole fractions. The molar refraction changes were correlated as a function of the volume fractions. The partial molar volumes at infinite dilutions were determined from the apparent molar volumes. Negative values for both the excess molar volumes and the molar refraction changes were observed over the entire range of mole fractions, whereas the viscosity data exhibited positive deviations from linearity.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
