Abstract

fetched live from OpenAlex

The anisotropy and phonon focusing of MgS are investigated through continuously elastic medium theory and physical acoustics theory in the solid state. The anisotropy and phonon propagation are theoretically researched in three–dimensional figures and their projections. The contours of three dimensional slowness surfaces give insights into the mixing of longitudinal modes and transverse modes, and show the origin of the phonon caustics due to the fact that the phonon phase velocity and group velocity are generally not collinear in elastically anisotropic crystals. The comparative investigations between anisotropy and slowness show that the propagation of elastic wave is affected by the elastic anisotropy of the lattice, and the phonon caustics “walk along” the extreme direction of elastic anisotropy.

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.
