Abstract

fetched live from OpenAlex

A new strategy for producing ordered polymeric films is proposed, which employs replication of interfacial instabilities. In the first step, a thin film of a monomeric fluid is brought in contact with a nonpolymerizable template layer of poly(dimethylsiloxane), and surface tension-driven convection is induced in the template liquid. In the second stage, Bénard cells replicated in the monomeric layer by a viscous drug are trapped in the solid state by UV-induced polymerization. Following this step, the template fluid is removed. The topographic patterns "frozen" in the polymeric film have lateral and vertical periodicity determined by the properties of the template fluid.

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.

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.
