Abstract
Abstract The interphase region in an epoxy - aluminum adhesive bond has been micromechanically characterized using a new acoustic microscope which employs a coupling fluid with a low speed of sound. A V(z) curve fitting method was used to calculate the property profiles across the interphase. The interphase region appeared to have shear and longitudinal wave speeds which were, on average, 14% and 11% larger than those of the bulk adhesive, respectively. The average interphase density was 5.5% smaller than the bulk density. The results were in conformity with a previous microscopic and nano-indentation study on the same adhesive system.

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
