Abstract

fetched live from OpenAlex

The Courant-Friedrich-Levy (CFL) stability condition makes the explicit finite-difference time-domain (FDTD) methods computationally expensive in applications where small cell sizes are needed to resolve high variations of fields. To circumvent the problem, unconditionally stable alternate-direction implicit (ADI)-FDTD method has been recently proposed. However, its uses are limited by large errors associated with larger time steps. In this letter, based on the Crank-Nicolson FDTD methods, we propose two new ADI-FDTD methods with reduced errors at large time steps. Numerical examples are presented to demonstrate the methods.

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.
