Abstract

fetched live from OpenAlex

Linear dose response in the range 0–30 Gy was observed in spin-lattice and spin-spin relaxation rates of water protons in 10 wt% sugar Fricke solutions at 300 MHz and 25 MHz. Spin-lattice dose sensitivities were higher at 300 MHz (0.058 s−1 Gy−1 with xylenol orange, 0.024 s−1 Gy−1 without) than at 25 MHz (0.047 s−1 Gy−1 with xylenol orange, 0.026 s−1 Gy−1 without), despite slightly less linearity. Spin-spin dose sensitivities at 25 MHz (0.029 s−1 Gy−1 with xylenol orange, 0.033 s−1 Gy−1 without) were slightly higher than corresponding spin-lattice dose sensitivities. Unirradiated sugar was found to accelerate background oxidation in Fricke solution, following a logistic time development curve.

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.
