Abstract
Results of X-ray fluorescence measurements of MA 2 Ca n-1 Cu n O 2n + 3 compounds with [ M -12(n-1)n] type structures, ( C 0.8 N 0.2 Sr 2 CuO 5.3 , [ Cu 0.25 (C,N) 0.75 ] Sr 2 CaCu 2 O y , Cu 0.5 V 0.5 Sr 2 CaCu 2 O 7.5 , Cu 0.5 V 0.5 Sr 2 Ca 2 Cu 3 O 9.4 , Cu 0.5 V 0.5 Sr 2 ( Ca 3.6 Sr 0.4 ) Cu 5 O 13.5 and Cu 0.5 V 0.5 Sr 2 ( Ca 4.7 Sr 0.3 ) Cu 6 O 15.3 , are presented. The experiments show that C-atoms form a distorted CO 3 oxyacid group with a partial substitution of copper and nitrogen atoms in the M-sites. We conclude that the CO 3 2- group in (C,N) Sr 2 Ca n-1 Cu n O y and (Cu,C,N) Sr 2 Ca n-1 Cu n O y is substituted by the NO 2 - which induces the creation of the hole carriers in these compounds. We have found that V-atoms in the given compounds form ( VO 4 ) 3- tetrahedrons and have a pentavalent state.

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 it
