Abstract
Retro-reflective Bragg gratings were made with a phase mask and femtosecond radiation from a Ti : sapphire infrared laser into the core and cladding region of a tapered single-mode fiber. The evanescent field in the taper interacts with the ambient environment and the intensity of the reflected signal is used to measure the refractive index changes of the ambient environment as low as 2.5/spl times/10/sup -5/. By controlling the immersion depth of the grating taper, use of the taper as a single port point sensor for measuring fluid levels is also demonstrated.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
