Abstract

fetched live from OpenAlex

Adjusting the pore size and volume of molecular sieve MCM-41 over a very wide range is possible through simple hydrothermal treatment of “off the shelf”, as-synthesized materials in a decyldimethylamine (DMDA)–water emulsion (see schematic representation). The amine/silica ratio as well as the time and temperature of the treatment are the main parameters that control the pore size expansion process.

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.
