Abstract
The fatigue effect has been studied experimentally in stoichiometric lithium tantalate single crystals produced by vapor transport equilibration with solid-state electrodes. It was shown that fatigue effect is due to increase of the frozen domain area composed of domains with charged domain walls (CDW). The formation of CDW: 1) hampers the domain kinetics by wall motion, 2) makes partial switching easier resulting in increase of the dielectric response, 3) decreases the threshold fields as the nucleation starts at the boundaries of frozen areas. The dependence of switched charge fraction on the cycle number has been analyzed by modified Kolmogorov-Avrami formula.

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
