Abstract

fetched live from OpenAlex

Polymer capsules were prepared by photostimulated precipitation of azobenzene-functionalized poly(styrene- alt -maleimide) copolymers dissolved in an oil phase and dispersed in a continuous aqueous phase. The oil phase is selected to be a near ϑ-solvent for the copolymers, such that the increasing polarity of the polymer due to the photochemical trans-to-cis isomerization induces polymer phase separation and migration to the interface. The resulting polymer walls are permanent even during storage in the dark or irradiation with visible light.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
