Abstract

fetched live from OpenAlex

Dielectric spectra of ${\mathrm{TiBO}}_{3}$ single crystals, grown by the chemical vapor transport technique, have been studied at temperatures between 40 and 200 \ifmmode^\circ\else\textdegree\fi{}C and frequencies from 100 Hz to 1 MHz. The shape of the spectra is well parameterized in terms of the temperature-independent Kohlrausch-Williams-Watts (stretched exponential) form, modified with the superimposed low-frequency dispersion and dc component. A deviation of the relaxation time from the Arrhenius law has been observed, which cannot be fitted into the known formulas. This deviation is phenomenologically explained by the screening effect. A formula has been proposed to describe such a complex dielectric relaxation behavior that is expected to exist in many more materials.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
