Abstract

fetched live from OpenAlex

Evanescent liquid sound-pressure waves are standing waves of limited spatial extension. These waves involve variable pressure and liquid-particle velocity but negligible liquid-density variation: they are predicted to occur also in strictly ideal liquids. The present note is intended to show that classroom demonstrations of these latter waves can provide a plausible introduction to the subject of spring-driven evanescent liquid sound-pressure waves. That inaccuracy occurs because the small- displacement approximation has been used. In both cases, standing waves with linear oscillations of liquid particles along time-independent streamlines are generated. Since thermal motion and diffusion of the molecules are neglected, in the no-wave state the liquid particle is concluded to keep its initial place and shape.

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.
