Imaging Molecular Chemistry of Pioneer Corn
Bibliographic record
Abstract
Synchrotron Fourier transform infrared (FTIR) microspectroscopy as a rapid, direct, and nondestructive analytical technique can explore molecular chemical features of the microstructure of biological samples. The objective of this study was to use synchrotron FTIR microspectroscopy to image the molecular chemistry of corn (cv. Pioneer 39P78) to reveal spatial intensity and distribution of chemical functional groups in corn tissue. This experiment was performed at the U2B station of the National Synchrotron Light Source in Brookhaven National Laboratory (NSLS-BNL, Upton, NY). The Pioneer corn tissue was imaged from the pericarp, seed coat, aleurone, and endosperm under peaks at 1736 (carbonyl C=O ester), 1510 (aromatic compound), 1650 (amide I), 1550 (amide II), 1246 (cellulosic material), 1160 (CHO), 1150 (CHO), 1080 (CHO), 929 (CHO), 860 (CHO), 3350 (OH and NH stretching), 2929 (CH(2) stretching band), and 2885 cm(-1) (CH(3) stretching band). The results showed that with synchrotron FTIR microspectroscopy, the images of the molecular chemistry of Pioneer corn could be generated. Such information on the microstructural-chemical features of grain corn can also be used for corn breeding programs for selecting superior varieties of corn for targeted food and feed purposes and for prediction of corn quality and nutritive value for humans and animals.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
