Abstract

fetched live from OpenAlex

X-ray photoelectron and emission spectra (XPS and XES) of diamond and graphite have been analyzed by deMon density-functional theory (DFT) calculations using the model adamantane derivative (C10H12(CH3)4) and pyrene (C16H10) molecules, respectively. The theoretical valence photoelectron and C Kα X-ray emission spectra for the allotrope are in good accordance with the experimental ones. The combined analysis of the valence XPS and C Kα XES enables us to divide the valence electronic distribution into the individual contributions for pσ-, and pπ-bonding MOs of the diamond and graphite, respectively. © 2000 John Wiley & Sons, Inc.

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.
