Abstract

fetched live from OpenAlex

Air Liquide has paid $21 million for a 19% stake in Hydrogenics, a Canadian maker of fuel cells and equipment for generating hydrogen. The two plan to jointly develop proton exchange membrane electrolysis technology for hydrogen energy markets. Mitsui & Co. and Ishihara Sangyo Kaisha have jointly purchased a 25% stake in Ouro Fino Quimica, a Brazilian agrochemical company. Mitsui says the company, founded in 2010, has developed “top-notch” formulas for the Brazilian market. EverZinc, the former Umicore zinc chemical business, has acquired GH Chemicals, a Canadian maker of zinc oxide with 58 employees. The acquisition is EverZinc’s second since OpenGate Capital acquired it in 2016. Kyocera has acquired H.C. Starck Ceramics, a German ceramics maker, for an undisclosed sum.

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.
