Abstract
This study proposes a comprehensive theory for the propagation of structured electron beams along atomic columns in crystals, by means of classical multislice and reformulated Bloch-wave algorithms, in the context of transmission electron microscopy. In particular, by making use of the symmetries of Bessel beams and Gaussian beams, the authors offer a clear description of the oscillatory behavior of the electron probe, including the dephasing of such an oscillation. This result provides a fresh methodological approach for the study of electron channeling, for the engineering of any desired depth behavior within a crystal, based on the initial probe shape.

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
