Abstract

fetched live from OpenAlex

Chirality transfer from chiral to achiral molecules can occur through hydrogen-bonding interactions. In their Communication on page 2073 ff., Y. Xu and C. Merten use matrix-isolation vibrational circular dichroism spectroscopy to measure the spectral signatures of chirality transfer from methyl lactate to ammonia, data which cannot be obtained in solution owing to the immediate protonation of ammonia (graphic by W. Jäger).

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.
