Abstract

fetched live from OpenAlex

In order to better accommodate the actual ecological environment, a more practical predator-prey model with fear effect, predator-taxis and degeneracy in spatially heterogeneous environment is proposed and analyzed in this paper. We are mainly concerned with positive steady state solutions and we investigate not only the individual effect of degeneracy but also the combined effects of predator-taxis and degeneracy on the such solutions of the models. Our results not only demonstrate some similarities but also reveal differences between the models with and without predator-taxis that partially reflects the fear effect.

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.
