Abstract

fetched live from OpenAlex

We report a synchrotron study of GeO2 nanowires (NWs) prepared by a vapor- liquid-solid (VLS) method on a silica glass substrate. The electronic and local structure of GeO2 NWs were studied by X-ray Absorption Near-Edge Structure (XANES) at the O K- and Ge L3,2-edges. X-ray Excited Optical Luminescence (energy and time resolved) were used to monitor the optical emission upon X-ray absorption with the excitation energy tuned across absorption edges of interest. Using this method one obtains site specific insight into the chemical origin of luminescence.

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.
