Abstract
We show that in monomeric supercooled liquids and glasses that are plastically flowing at a constant shear stress $\ensuremath{\sigma}$ while being deformed with strain rate $\stackrel{\ifmmode \dot{}\else \.{}\fi{}}{\ensuremath{\epsilon}}$, the microscopic structural relaxation time ${\ensuremath{\tau}}_{\mathrm{str}}$ is given by the universal relation $\ensuremath{\sigma}/{G}_{\ensuremath{\infty}}\stackrel{\ifmmode \dot{}\else \.{}\fi{}}{\ensuremath{\epsilon}}$ with ${G}_{\ensuremath{\infty}}$ a modulus. This equality holds for all rheological regimes from temperatures above the glass transition all the way to the athermal limit, and arises from the competing effects of elastic loading and viscous dissipation. In macromolecular (polymeric) glasses, however, the stress decouples from this relaxation time and ${\ensuremath{\tau}}_{\mathrm{str}}$ is in fact further reduced even though $\ensuremath{\sigma}$ rises during glassy strain hardening. We develop expressions to capture both effects and thus provide a framework for analyzing mobility measurements in glassy materials.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
