Abstract

fetched live from OpenAlex

HbN and HbO are two truncated hemoglobins from Mycobacterium tuberculosis. Resonance Raman spectra of the deoxy derivatives of these two homodimeric hemoglobins indicate that there is no proximal strain imposed by intersubunit interactions on the proximal iron-histidine bond as that observed in the tetrameric human hemoglobin. In addition, with nanosecond laser flash photolysis, it was concluded that movement along the Fe-His bond following the dissociation of CO does not trigger a quaternary structural transition in these two hemoglobins.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
