Abstract

fetched live from OpenAlex

The equal width equation has been solved numerically using the Galerkin finite-element method, based on the Adams-Moulton method for time integration and quadratic/cubic B-splines for space integration. The two proposed algorithms are tested on the problems of propagation of a solitary wave and interaction of two solitary waves. For the first test problem, the convergence rate is computed for the proposed algorithms and the L ∞ error norm is used to measure the differences between the exact and numerical solutions. The three conserved quantities of motion are calculated to determine the conservation properties of the two proposed algorithms for both test problems.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
