Abstract

fetched live from OpenAlex

The essential oil from Malania Olceifera Chum was extracted by steam distillation,and the chemical components were identified and determined by gas chromatography-mass spectrometry(GC-MS) method.The results show that the yield of essential oil was 1.3% from peel and flesh of Malania Olceifera Chum,and 6 compounds(99.37%) of 10 chromatographic components in the oil were identified.The major constituents include benzaldehyde(78.79%),benzyl alcohol(14.69%),mandelonitrile(4.74%),benzoic acid(0.15%),benzyl benzoate(0.12%),α-cyanobenzyl benzoate(0.88%).The yield of oil extracted from the branches and leaves was 0.3%,which contains 6 chromatographic components and 4 compounds(99.6%) in that were identified,the major components were benzaldehyde(61.88%),benzyl alcohol(1.51%),mandelonitrile(24.80%) and benzoic acid(11.32%).The yield of benzaldehyde was 80.8%,purity was 98% by vacuum rectification in N2.

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.
