Abstract

fetched live from OpenAlex

A novel structure in which a short optical fiber stub containing a weakly tilted Bragg grating is spliced to another slightly offset fiber. The total power reflected from this structure is independent of temperature and occurs in two well-defined wavelength bands, only one of which reflects a different amount of power as the fiber stub bends or vibrates. The smart sensing structure presents an extremely high sensitivity for microbending, and its frequency response has been tested to higher than 2 kHz so far in temperature-immune vibration measurements via cost-effective power detection.

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.
