Abstract

fetched live from OpenAlex

Two triblock copolymers of the poly(butyl methacrylate)- block -poly(2-cinnamoyloxyethyl methacrylate)- block -poly( tert -butyl acrylate) or PBMA- b -PCEMA- b -P t BA family were synthesized and characterized. The triblocks had PCEMA to P t BA volume ratios ≥1.3 and PBMA volume fractions ≥0.56. Their bulk morphologies consisted of cylindrical domains with P t BA cores and PCEMA shells dispersed in the PBMA matrix. Nanofibers of PBMA- b -PCEMA- b -P t BA were obtained after cross-linking PCEMA photochemically and separating the cross-linked cylinders from dissolved PBMA chains. PBMA- b -PCEMA nanotubes with PAA-lined channels were obtained after tert -butyl group removal from the P t BA cores by selective hydrolysis.

Full frame distilled prediction

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.
