Abstract

fetched live from OpenAlex

We introduce a Rayleigh equivalent criterion to measure stressed section shorter than the spatial resolution of a distributed Brillouin sensor. Under this criterion for the worst-case of any given sensing length, the minimum resolvable strain length is 1/2 of the pulse length (w) with Brillouin frequency uncertainty of 5% or 0.8w with 2% frequency uncertainty. This is smaller than the pulse length.

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.
