Abstract

fetched live from OpenAlex

A gold nanoparticle (Au NP)-based plasmonic tongue is shown to correlate well with the emergence of flavor defects in the late season harvest of maple syrup, validated with a representative sampling of 29 304 maple syrups of different grades. The daily average temperatures, pH, transmittance, °Brix, and total and individual amino acid concentrations provided evidence that the plasmonic tongue responds to amino acid concentrations, which is then correlated to an off-flavor index. The amino acid to sugar ratio decreased significantly in syrup compared to sap, a result of their consumption in the Maillard reaction during the boiling process. An ordinal mixed-effect model was shown to accurately predict the amino acid concentrations and the most likely grading class of maple syrup from the plasmonic tongue’s response. Taken together, the plasmonic tongue with the mathematical model could serve as a predictor of the output quality of maple syrup from maple sap at the production site.

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.
