Abstract
The motion of high-intensity aerial converged ultrasonic waves (frequency: 20 kHz) as studied as they entered a perforation which had a smaller diameter than the wavelength of the radiated acoustic waves (approx. 17.4 mm). In addition, the characteristics of the sound field created in the perforation were studied experimentally. The acoustic waves incident upon the perforation were convergent, having a spreading angle of approx. 90°. As a result, it was elucidated that the acoustic waves favorably entered the perforation with a sufficiently smaller diameter (5 mm max) than the wavelength of the acoustic waves. A sound field of standing waves was created with the sound pressure being the maximum at the bottom of the perforation. The sound pressure increased in the ratio of the 0.5th power of the electric power supplied to the sound source. When the electric power supplied to the sound source was 50 W, a very powerful ultrasonic field of approx. 170 dB was created at the bottom of the perforation.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
