Abstract

fetched live from OpenAlex

Seeds are complex entities, within which the intricate processes of germination and early growth occur. We describe here a novel technique of our group in 2012 which is capable of simultaneous solution-, gel-, and solid-state analysis. CMP-NMR was applied to intact seeds where all components are studied and differentiated in situ.\nCharacterization, germination and early growth of seeds were studied by variety of 1D\nand 2D 1H and 13C CMP-NMR experiments. Various metabolites, lipids, carbohydrate\nbiopolymers and structural carbohydrates were first identified and further studied in\ngermination and early growth stages. This research demonstrates the utility of CMP-\nNMR as a powerful tool to better understand the composition of seeds and processes\nunderlying early seed growth.

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.
