Abstract

fetched live from OpenAlex

Insecticidal activity of Daphne tanutica, a local endemic plant from Qinghai-Tibet plateau, was first reported in this paper. The air-dried and powdered plant was extracted with methanol, acetone, ethyl acetate, chloroform, benzene and petroleum ester, and the results showed that foe extractive rate in methanol was the largest (22. 34% ), and the smallest (2. 21% ) in petroleum ester. The crude extracts of former five solvents were proved to possess strongly antifeeding effect on the 3rd instar larvae of tobacco cutworm, Spodoptera litura, through the preliminary bioassay with AFC50s of 108. 72, 111. 69, 102. 14, 71. 15 and 65. 51 g dried powder/L. At concentration of 500 g dried powder/L, antifeedant effect of the petroleum ester extract against the tested insects was 62. 31 %. Therefore benzene was the most effective extracting solvent.

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.

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.
