Abstract

fetched live from OpenAlex

Using a nonlinear critical layer analysis, we examine the behavior of disturbances to the Holmboe model of a stratified shear layer for Richardson numbers 0<J≤1/4, regarding J as an ϑ (1) quantity rather than a small quantity. By examining the structure of the solution inside the critical layer, we demonstrate that, for this particular flow, disturbances with a phase change of the form predicted by linear stability theory cannot exist on a purely linear basis, and because of this, an instability wave will have no phase change across the critical layer, and that instead we should regard the Richardson number J as a small quantity within the framework of a nonlinear analysis. We argue further that when nonlinear effects are included, disturbances with a phase change can exist, but this leads to such a slow time scale that the flow in question is unlikely to arise, except possibly as a secondary instability.

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.
