Abstract
Understanding chemical transformations in polymethylmethacrylate (PMMA) during helium ion beam exposure will help researchers involved in nanofabrication, materials synthesis or transformation, patterning polyenes, developing phantoms for radiation therapy, and realizing carbonaceous quantum emitters. The level of conjugation in PMMA can be controlled using a helium ion beam to realize patterns that are suitable for positive tone lithography, polyenes, dye‐like fluorescent materials, and polycyclic aromatic compounds with very similar properties to carbon dots. High‐resolution dose studies employing Raman scattering and atomic force microscopy (AFM) reveal the conditions under which these very different conjugated carbonaceous materials form, their spatial distribution, and dissolution characteristics in common solvents.

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
