Abstract

fetched live from OpenAlex

The structural characterization of Al 2(PO 4)(OH) 3augelite, a natural orthophosphate coming from Rapid Creek, Yukon, Canada, was carried out by means of a multi-methodological approach based on WDS-EMPA chemical analysis, single crystal X-ray diffraction, and infrared spectroscopy. The structure was solved in the C2 /mmonoclinic space group, with the following unit cell constants: a= 13.0740(10), b= 7.9690(7), c= 5.0910(7) Å, β= 112.282(5)°, V= 490.81(9) Å 3. Phosphorus atoms display tetrahedral (PO 4) coordination, while aluminum cations display octahedral and unusual five-fold coordination. The framework of the mineral can be viewed as the repetition of cationic arrays made up by AlO 6/AlO 5polyhedra, bridged by PO 4groups, and further joined by O–H···O hydrogen bonds: such interactions were also correlated to IR spectroscopy analysis, by means of Libo­witzky formula applied on OH stretching vibrations.

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.
