Abstract

fetched live from OpenAlex

To properly model highly entropic inhomogeneous materials in the canonical ensemble by molecular dynamics simulations, it is necessary to choose algorithms which rigorously implement the ensemble. Approximate methods may have either very low efficiency or completely fail in the very soft regime. The calculation of the shear modulus of the diluted central force network is used to illustrate this point. Four algorithms to realize the canonical ensemble have been tested on two methods of evaluation of the shear modulus.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
