Abstract

fetched live from OpenAlex

Abstract Two possible variation approximations for the exchange‐correlation interaction are considered in the one‐particle approach to the electronic structure theories. These approximations appear within the Super‐CI procedure in the MCSCF optimization schemes. The basic formalism shows its close connection to the Green's function theory in the extended Koopmans' approach. An immediate implementation of the corresponding Super‐CI Green's functions is the Møller‐Plesset open‐shell and quasi‐degenerate perturbation expansions, and the density matrix functional theory. The relativistic formulation which is based on the relativistic extended Koopmans' approach can be used to calculate radiation corrections in frames of the conventional Feynman formalism. © 2007 Wiley Periodicals, Inc.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
