Abstract

fetched live from OpenAlex

Around 83 B.C., give or take a century, comet Kiess (C/1911 N1) passed by the Sun, ejecting a cloud of dust particles. The comet returned in 1911, after completing one orbit. The dust particles were pushed by solar radi-ation pressure into slightly wider orbits and have been returning ever since, forming a thin ongoing stream of dust that usually passes just outside Earth’s orbit. On occasion, the combined gravity of the solar system’s plan-ets moves this dust trail into Earth’s path. Earth encountered this 2000-year-old dust in 1935, 1986, and 1994, causing a meteor shower known as the Aurigids. This very rare shower will occur again on 1 September 2007. A brief shower of tens of meteors will radiate from the constellation of Auriga, many as bright as the brighter stars in the sky. The Earth will be in the thick of it during the 1 hour centered on 0436 PDT. The shower will be visible with the naked eye from locations in the western United States, including Hawaii and Alaska, from Mexico, and from the western provinces of Canada

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.
