Abstract
Covalently linked pairs of cross-linked hemoglobin tetramers ("bis-tetramers", shown schematically as 6-8) were prepared by reacting hemoglobin A with tetrakis acyl phosphate esters (3-5). The effects of the link between tetramers are observed in the oxygen-binding properties of the bis-tetramers: they bind oxygen cooperatively but with Hill coefficients (n(50)) lower than that of the native protein and with a high average affinity. The bis-tetramers with longer connections between tetramers show a higher n(50), suggesting that steric interactions between the tetramers affect cooperativity. These results correlate to the observed reduced vasoactivity of heterogeneous solutions of oligomeric cross-linked hemoglobin tetramers.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
