Abstract

fetched live from OpenAlex

Based on the former research results,the green nephrite from Taiwan has been experimented by SEM,XRD and FTIR and the experimental results are compared with the green nephrite from Canada.The results indicate that the green nephrite from Taiwan mainly consists of tremolite,small amounts of actinolite and chlorite.The tremolite shows fibrous structure under microscope which arrays intensively along the macro-axis and interweaved closely.Cell parameters of the green nephrite from Taiwan calculated by XRD show that the crystallinity goes up to 94.62%.Besides,the content of Fe2+ in the green nephrite from Taiwan is much higher than that in the green nephrite from Canada.Among IR spectra,the bands near 3 674 cm-1 identify the band of OH stretching vibration,the bands near 900—1 150 cm-1 identify Si4O11 stretching vibration,the bands near 600—800 cm-1 identify the γs(Si-O-Si) vibration,the bands near 400—600 cm-1 identify the coupling of Si—O bending vibration,Mg—O stretching vibration and OH parallel vibration.

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.
