Abstract

fetched live from OpenAlex

Statistics of China's sulphur import and analysis of domestic market in 2011 are carried out.China imported sulphur 9 523.2 kt in 2011,a decrease of 9.21%compared to 2010.In the first half of the year,sulphur price rose continuously and reached peak of about 1 800 RMB/t in early June in East China market.And in the second half of the year,the market fell into a sluggish and fragile status with the price below 1 700 RMB/t at the end of the year.In 2011,the main sulphur suppliers for China were Saudi Arabia,Kazakhstan and Canada and China's sulphur purchase concentrated in Jiangsu,Yunnan,Guizhou,Shandong,Hubei el at.

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.
