Abstract

fetched live from OpenAlex

The solubility of Np(Ⅳ) in simulated underground water and redistilled water has been measured with the variations of pH(6~12) and storage time(0~100 d) in the presence of reductants(Na 2S 2O 4, metallic Fe). All experiments are performed in a low oxygen concentration glove box containing high purity Ar(99.99 %), with an oxygen content of less than 5×10 -6 mol/mol . Experimental results show that the variation of pH in solution has little effect on the solubility of Np(Ⅳ) in the two kinds of water; the measured solubility of Np(Ⅳ) is affected by the composition of solution; with Na 2S 2O 4 as a reductant, the solubility of Np(Ⅳ) in simulated underground water is (9 23±0 48)×10 -10 mol/L, and that in redistilled water is (8 31±0 35)×10 -10 mol/L; with metallic Fe as a reductant, the solubility of Np(Ⅳ) in simulated underground water is (1 85±0 56)×10 -9 mol/L, and that in redistilled water is (1 48±0 66)×10 -9 mol/L.

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.
