Abstract
The first Director of the Division of Applied Physics brought with him a strong interest in ultrasonics, thereby opening a line of research in acoustics, which has continued unbroken even since. It was George J. Thiessen, Section Head from 1950 to 1975, who rebuilt the acoustics section after the war effort and charted the course the laboratory follows today. It was in the early 50s that Edgar Shaw and Tony Embleton joined the laboratory. They were both students of R. W. B. Stephens, a research supervisor who has taught and inspired a generation of acoustics students and guided them in the attainment of excellence. During the over 50 intervening years, several generations of acousticians have studied and been mentored in the laboratory. Most of the students and post-docs that have spent time in the laboratory now hold faculty, government, or industry positions in acoustics.

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
