Agriculturalization of the Nomad‐Dominated Empires of the Northern Wei Dynasty in Pingcheng city (398–494 <scp>ad</scp>): A stable isotopic study on animal and human bones from the Jinmaoyuan cemetery, China
Bibliographic record
Abstract
Abstract To investigate the agriculturalization of the Nomad‐Dominated Empires of the Northern Wei Dynasty, we analysed the δ 13 C and δ 15 N values of animal and human bone/dentine collagen from the Jingmaoyuan cemetery, Datong city, China. The majority of the Jingmaoyuan humans predominately relied on a diet of C 4 plants, likely millets and/or domestic animals fed on by‐products of millet. Other individuals had a C 3 /C 4 mixed diet, indicating diets with more protein from domestic animals and/or freshwater fish. The economy of millet‐based agriculture and diversified animal husbandry together with the integration between the nomadic Tuoba Xianbei and Han Chinese in Pingcheng city probably were driving forces behind the agriculturalization and development of the Northern Wei Pingcheng period (398–494 ad ).

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
