Abstract
We investigate the response of amorphous silicon ($a$-Si) to external mechanical shear deformations using classical molecular dynamics simulations and the empirical environment dependent interatomic potential [Phys. Rev. B 56, 8542 (1997)]. In agreement with previous results, we find that, at low shear velocity and low temperature, shear deformations increase disorder and defect density. At low shear and high temperature, the deformations are found to induce crystallization, demonstrating a dynamical transition associated with both shear rate and temperature. The properties of $a$-Si under shear deformations and the extent at which the system crystallizes are analyzed in terms of the potential energy difference between the sheared and nonsheared material, as well as the fraction of defects and the number of particles that possess a crystalline environment.

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
