Abstract

fetched live from OpenAlex

The Michelson‐Morley optical interferometric experiment is historically very important and stands at the basis of the developments that contributed to the acceptance of the special theory of relativity.1 The Sagnac experiment is much less known and considered from the theoretical point of view, even if it presently has a large field of very useful technological applications, namely in the field of compass gyroscopes. Here, we present a discussion on the temporal precision of these devices that undoubtedly shows the great advantage of the Sagnac device design.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
