Abstract

fetched live from OpenAlex

The upper and lower solution method is a recently developed and currently the most effective tool for determining the sign of bistable traveling wave. However, for systems with nonlocal diffusion terms, it is extremely challenging to find upper and lower solutions. In this paper, we develop a new idea for constructing the upper and lower solutions to establish the explicit conditions for obtaining positive or negative wave speed for a Lotka-Volterra competitive system with bistable nonlinearity. The theoretical results are demonstrated by directly integrating the considered system. This method can be used to improve or correct the related results in the known references.

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.
