Abstract

fetched live from OpenAlex

Spectroscopic measurements are amongst the most important optical experimental methods with applications ranging from physics to chemistry, material science, and biology [1] . Conventionally, spectroscopy is performed by measuring wavelength-dependent changes in the transmitted light. In one recent study, it was shown that a strong correlation between a transverse position and the polarization in spatial vector beams can be beneficially applied in high-speed kinematic sensing [2] . We extend this idea to the spectral domain and generate states of light, in which beams have a varying polarization vector across their frequency spectrum. We term such states of light spectral vector beams and use them for spectroscopic measurements.

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.
