Abstract

fetched live from OpenAlex

We have synthesized and characterized novel, copper-metalated, polymeric templates that contain adenine nucleobases. These promote hydrolysis of non-natural and natural phosphate ester substrates in a highly efficient and catalytic fashion. The crystal structure of the cooper-containing adenylated monomer reveals the formation of a polymeric array, through coordination to both N1 and N7 atoms. Possible implications of these studies for prebiotic catalysis, involving synergism between adenine and copper ions, are also discussed.

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.
