Abstract

fetched live from OpenAlex

Abstract The effects of dissolved carbon dioxide (CO 2 ) molecules on the glass‐transition temperature as well as the crystallization kinetics of poly(lactic acid) have been investigated with a novel device that combines ultrasonic and volumetric measurements. Ultrasonic parameters such as the sound velocity are very sensitive to crystallization and can be used to monitor the crystallization kinetics. The glass‐transition temperature has been found to decrease nonlinearly as the CO 2 concentration increases. The maximum in the crystallization rate has been found to increase with the addition of CO 2 . © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009

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.
