STABILITY CONSTANTS FOR GLYCINE UNDER HYDROTHERMAL CONDITIONS USING COLORIMETRIC INDICATORS
Bibliographic record
Abstract
Hydrothermal conditions are known to occur at deep ocean hydrothermal vents, where thermophilic life is hypothesized to exist. Amino acids under hydrothermal conditions are of interest as knowledge of their properties will contribute to theories of hydrothermal vents as possible sources for the origin of life. Amino acids, such as glycine, are zwitterions and have both basic and acidic dissociation reactions in solution. Glycine is known to have a limited stability under hydrothermal conditions (Clarke, Ph.D. Thesis, Memorial University of Newfoundland, 2000), thus stability constants for these reactions are not known above 423 K. In this work a UV-visible spectrophotometer and flow system with the colorimetric indicators acridine, 2-naphthol, and 2-naphthoic acid, developed by Xiang and Johnston (J.

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.
