Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

최근 캄브리아기 초기에 해당하는 동물군 화석이 중국 운남성 부근에서 다량 발견되었다. 이 동물군 화석은 5억 2천만 년 전에서 5억 2천 5백만 년 전의 연대를 가진 마오탕샨 셰일에서 산출되며, 캐나다 로키의 버제스셰일동물군과 그린란드의 시리우스파세트동물군보다 약 1천만년 내지 2천만년 더 오래된 동물군으로 판단된다. 청지앙동물군은 아주 다양한 동물 화석으로 구성되며, 몸체의 약한 부분이 잘 보존되어 있다. 이러한 조건은 유수, 생란 작용, 생화학 작용을 받지 않는 환경 즉 반복된 빠른 퇴적작용에 의해서 화석화된 것이다. Recently lots of the Early Cambrian fauna were described from the Yunnan Province of China. The fauna occurs from the Maotiangshan shale that dated between 525 and 520 ma, which is about 10-20 million years earlier than the Burgess Shale fauna of Canadian Rocky Mountain and Sirius Passet fauna in North Greenland. The Chengjiang fauna comprises an extremely diverse faunal assembly, and soft body parts of the fauna are well preserved. Such condition probably resulted from repeated rapid burial environment that prevented the bodies from destruction by currents, bioturbation, and biolchemical activities.

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.
