Abstract
Abstract Nuclear magnetic resonance (NMR) spectroscopy, or magnetic resonance spectroscopy (MRS), is a powerful physical technique to determine the quantity and structure of chemical compounds in a specimen. It involves the interaction of radiofrequency (RF) electromagnetic radiation with a collection of nuclei immersed in a strong magnetic field. It is unique in its ability to provide nondestructive chemical analyses in vivo and in vitro. Moreover, no or very little pretreatment of the specimen is required prior to making a measurement. Spectra take only a few minutes to acquire, and it is not necessary to preselect the metabolites of interest in order to detect and quantify them. Its limitations are a lack of availability of instruments and large databases of spectral changes correlated with pathological conditions, and a detection sensitivity of approximately 1 µM.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
