Abstract

fetched live from OpenAlex

A technique is proposed for reducing unwanted diffraction contrast when imaging second phases in crystalline materials using transmission electron microscopy. With the suggested name of plasmon-ratio imaging, the technique uses an energy-filtered imaging system to record and determine a ratio for two images taken at energies in the low loss region. Unlike core-loss imaging, the use of very thin specimens is not required. It is concluded that it is often possible to create a ratio image in which the contrast is dominated by energy loss, that is, chemical differences, rather than by diffraction effects.

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.
