Abstract

fetched live from OpenAlex

山东莲藕(Nelumbo nucifera Gaertn.)栽培历史悠久,在中国北方具有重要影响。但是,山东莲藕种质资源研究一直没有开展。为收集和保存莲藕种质资源,本研究从山东省8个种植面积较大的地区采集了76份莲藕材料,并利用RAPD分子标记对这些材料进行了遗传相似性分析,共鉴定出38份种质资源。遗传多样性指数分析显示,38份种质资源的Nei’s多样性指数(H)平均值为0.26,Shannon信息指数(I)平均值为0.41。研究数据表明,山东莲藕种质资源相对丰富,但要建立高质量的种质资源圃,仍需要加强种质资源的引进。

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.
