Abstract

fetched live from OpenAlex

The Fourier transform approach to multicenter electronic integrals from molecules over Slater-type basis is briefly presented. A basis of B functions is used because of their compact Fourier transform. This leads to analytical expressions involving very oscillatory semi-infinite integrals for Coulomb and hybrid integrals over three and four atomic centers. These semi-infinite integrals are evaluated precisely and rapidly with the help of the new nonlinear HD and \documentclass{article}\pagestyle{empty}\begin{document}$H\overline{D}$\end{document} transformations which are based on the D and \documentclass{article}\pagestyle{empty}\begin{document}$\overline{D}$\end{document} transformations. Numerical values are tabulated and presented for a selection of molecular geometries and integrals with emphasis on improved precision and rapidity compared with alternatives methods. © 2000 John Wiley & Sons, Inc.

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.
