Abstract

fetched live from OpenAlex

Arrhenius parameters, obtained with the blackbody infrared radiative dissociation technique, are reported for the dissociation of gaseous protonated complexes of a single-chain variable fragment (scFv) of the monoclonal antibody Se155-4 with structurally constrained trisaccharide ligands that resemble the bioactive conformer. The similarity in the dissociation activation energies measured for the +10 charge-state complexes of the constrained ligands and the native trisaccharide is evidence that the bioactive conformation of the native ligand is retained in the gas phase.

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.
