Abstract

fetched live from OpenAlex

Harvesting of saltwater pearls in China extends back to 200 BC, but only in the last 30-40 years have cultured saltwater pearls been farmed there. Production is mostly from the Akoya pearl oyster Pinctada imbricata and is limited to the southern provinces of Guangxi, Guangdong, and Hainan, which have suitable water temperature. The first private saltwater cultured pearl farms were established in 1986. Production grew rapidly, and by 1995 it reached ~15 tons/year. Production subsequently reached ~20 tons/year, but recently it has decreased in both quality and quantity due to several factors (e.g., environmental degradation).

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.
