Abstract

fetched live from OpenAlex

Agelaea pentagyna (Lam.) Baill. is an endemic plant of Madagascar belonging to the Connaraceae family. The essential oil from leaves of this plant was extracted by hydrodistillation and analyzed by gas chromatography coupled with mass spectrometry (GC/MS), in order to determine the chemical composition of the volatile fraction and to identify the chemotypes of the species. The essential oil has a yellowish color and has a no odor; the yield was 0.05%. A total of fifty-nine compounds, 99.93% of its compounds are identified in the sample. The main compounds in the oil were δ-cadinene (16.284%), caryophyllene (10.151%), and benzylbenzoate (09.57%).

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.

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.
