Abstract

fetched live from OpenAlex

The results of investigations of the physical properties and electronic structure in the Hf x Ta1−x solid solutions have been generalized. The N 3 X-ray emission spectra Ta in hafnium and tantalum carbides have been investigated for the first time. Peak locations and intensities have been compared with the results of calculations of the electron band structure of Hf x Ta1−x C alloys with x = 0, 0.25, 0.5, and 0.75. It has been found that the inversion of peak intensities with increasing hafnium concentration is due to a nonmontonic variation in the density of Ta 5d states in the valence band of these compounds.

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.
