Abstract
It was previously shown that protein aggregation induced by gamma-irradiation can be prevented by L-tyrosine, even when irradiation was done in solution at doses as high as 10 kGy. It is now reported that caeruloplasmin irradiated at low to moderate doses appears more resistant to trypsin-mediated proteolysis than native caeruloplasmin. Ceruloplasmin presents an irradiation-dose-dependent decrease of oxidase activity and a slight increase of ferroxidase activity at low irradiation doses (2 kGy), followed by a decrease at high doses (4-8 kGy). In all cases, the catalytic activities are higher when caeruloplasmin is irradiated under tyrosine protection. Irradiated caeruloplasmin in the presence of tyrosine preserves its oxidase and ferroxidase activities. Caeruloplasmin irradiated in solution at a dose of 2-3 kGy and higher, in the presence and absence of L-tyrosine, remained sterile during at least 8 weeks of storage at 4 degrees C, as evaluated by the plate-count-agar method for assessing total viable lactic acid bacteria content after incubation for 48 h at 30 degrees C.

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
