Abstract

fetched live from OpenAlex

Many efforts in experimental and theory are dedicated to study the puzzling problem of glass transition. With the involvement of molecular modeling, a fresh look at this intricate phenomenon was taken. Nevertheless, the difficulty to accurately probe all the domains of times necessary to describe this process still remains. Moreover, using a full-atomic description to account for equilibrated systems has been called into question. However, such depiction offers a special regard since it could deal with small modifications in the polymer architecture. From an appropriate selection of phase space, it was shown that atomistic simulation was able to link simulated and experimental glass transition temperatures of vinylic polymers using the established Williams−Landel−Ferry equation. Consequently, atomic insight into the glass transition phenomenon can be gained from a comparison of simulated data with actual models and experimental data. In this paper, the different parameters intervening in the Vogel−Fulcher−Tamman equation stemming from the local dynamics of a series of vinylic polymers are thus compared. Their behavior yields an atomistic viewpoint of the Adam−Gibbs model.

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.
