Abstract

fetched live from OpenAlex

Raman active phonons of Yb doped LuVO4 ranging from 0.25% to 30% are detected and analyzed at low temperature in order to determine the doping effects on the crystalline quality and the phonon contribution to the crystal-field vibronics. Also, Yb3+ ion F7∕22 and F5∕22 crystal-field energy levels are measured as a function of doping by infrared absorption and luminescence. The appropriate crystal-field Hamiltonian parameters are determined and the presence of Yb3+–Yb3+ magnetically interacting pairs, which play an important role in cooperative emission, is confirmed.

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.
