Abstract
Modification of the microwave dielectric properties in Ba 6−3 x Nd 8+2 x Ti 18 O 54 ( x = 0.5) solid solutions by Bi/Sm cosubstitution for Nd was investigated. A large increase in the dielectric constant and near‐zero temperature coefficient combined with high Qf values were obtained in modified Ba 6−3 x Nd 8+2 x Ti 18 O 54 solid solutions where an enlarged solid solution limit of Bi in Ba 6−3 x Nd 8+2 x Ti 18 O 54 was observed. Excellent microwave dielectric characteristics (ɛ= 105, Qf = 4110 GHz, and very low τ f ) were achieved in the composition Ba 6−3 x (Nd 0.7 Bi 0.18 Sm 0.12 ) 8+2 x Ti 18 O 54 .

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
