Abstract

fetched live from OpenAlex

Getting the air out: A bottleneck in transition-metal chemistry is the laborious process of identifying organometallic molecules. Anaerobic, charge-transfer MALDI-MS is a powerful new tool for observation of these reactive, often fragile species. Examples are drawn from catalysts relevant to olefin metathesis, hydrogenation, polymerization, and cyclopropanation. IMes=N,N′-bis(mesityl)imidazol-2-ylidene.

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.
