Abstract

fetched live from OpenAlex

The studies of insulating specimen by using scanning electron microscopy (SEM) or associated microanalytical techniques such as electron probe microanalysis (EPMA), Auger electron spectroscopy (AES), etc., is limited by the charging phenomena. Different techniques have been found to minimize this problem: coating the specimen with a conductor, working at low energy [1], etc. But for a better knowledge of this effect, we have started a study of the mechanisms of charging as well as its effect on the electrons trajectories in the case of an insulating specimen. with the success, in past years, of Monte Carlo (MC) simulation of electron scattering in solid specimens [2], we have been developing a new Monte Carlo program for the simulation of the electron trajectory in insulators. With this program, we want to understand the effect of the trapping charge on a insulating specimen. The new MC will be constructed by adding a succession of refined model. in each step, the model goes deeper in the mechanisms for the charging phenomena.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
