Abstract

fetched live from OpenAlex

Exploiting the locality of the chemical potential of an excited state when it is evaluated using the ground state Density Functional Theory (DFT), a new local descriptor for excited states has been proposed (J. Chem. Theory Comput.2009, 5, 2274). This index is based on the assumption that the relaxation of the electronic density toward that of the ground state drives the chemical reactivity of excited states. The sign of the descriptor characterizes the electrophilic or nucleophilic behavior of atomic regions. Through an exact excited state DFT formalism provided by Gross, Oliveira, and Kohn, a mathematical argument is given for this descriptor only for the first excited state. It is afterward used to rationalize the occurrence and the regioselectivity of some DNA lesions based on the [2 + 2] cycloaddition between two adjacent bases.

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.
