Chemical speciation of arsenic in uranium mine tailings by X-ray absorption spectroscopy
Bibliographic record
Abstract
Afin de comprendre le monde changeant des questions environnementales, la capacite de comprendre et de predire la stabilite et la biodisponibilite decontaminants de metaux lourds dans les dechets demine devient de plus en plus importante. Les spectroscopies de structure pres du front d'absorption de rayon-X (XANES) et de structure fine etendue d'absorption de rayon-X furent utilisees pour caracteriser une serie d'echantillons synthetiques et naturels associes aux dechets de mine. XANES fut demontree comme etant un excellent outil pour differencier les etats d'oxydation de l'arsenic dans les echantillons. Les spectres d'EXAFS fournirent de l'information sur la mineralogie des raffinats et dechets precipites, et montrerent que ces echantillons sont composes d'un melange d'arsenates ferriques amorphes, d'arsenates adsorbes et d'un melange d'autres arsenates peu ordonnes.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
