Abstract

fetched live from OpenAlex

(NaIO4) [7790-28-5] INaO4 (MW 213.89) InChI = 1S/HIO4.Na/c2-1(3,4)5;/h(H,2,3,4,5);/q;+1/p-1 InChIKey = JQWHASGSAFIOCM-UHFFFAOYSA-M (OsO4) [20816-12-0] O4Os (MW 254.20) InChI = 1S/4O.Os InChIKey = VUVGYHUDAICLFK-UHFFFAOYSA-N (oxidizing agent for oxidative cleavage of carbon–carbon double bonds3 to give aldehydes and ketones) Physical Data: NaIO4: mp 300 °C (dec); specific gravity 3.865. OsO4: bp 130 °C; mp 40 °C; specific gravity 4.900 at 22 °C. Solubility: NaIO4: sol H2O (14.4 g/100 mL H2O at 25 °C; 38.9 g/100 mL at 51.5 °C), H2SO4, HNO3, acetic acid; insol organic solvents. OsO4: sol alcohol, Et2O, benzene, CCl4, NH3, POCl3, H2O (25%). Form Supplied in: NaIO4: colorless to white tetragonal, efflorescent crystals. OsO4: colorless to pale yellow crystals contained in ampules. Both reagents are readily available. Handling, Storage, and Precautions: NaIO4: irritant; gloves and safety goggles should be worn when handling this oxidant; avoid inhalation of dust and avoid contact of oxidant with combustible matter. OsO4: acrid, chlorine-like odor; irritant; highly corrosive; causes burns to skin, eyes, and respiratory tract; gloves and safety goggles must be worn and this reagent must be handled in a well ventilated fume hood.

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.
