Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

The crystal structure of a potentially new member of the eudialyte group, the Nb-deficient analogue of oneillite from Mont Saint-Hilaire, Québec, Canada, with the idealized formula: Na13(Ca3Mn3)Zr3(Fe,Mn)3(,Nb)(Si,Nb,) [Si3O9]2[Si9O27]2(O,OH,Cl)3•2H2O, has been re-studied within the space group P3. The unit-cell parameters are: a = 14.134(3), c = 30.178(6) Å, V = 52201 Å3. The crystal structure of the mineral has been previously investigated using the space group R3 (typical for the members of oneillite family). In this work a structural model characterized by 155 crystallographic sites was solved in the frame of the low symmetry space group P3 and refined to R = 5.9 % using 4179 reflections with F > 2(F). The cation distribution between the key sites in low symmetry is more detailed.

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.
