Abstract

fetched live from OpenAlex

The photolysis of a variety of fluorinated and chlorinated compounds was investigated under actinic radiation.Chloroacetanilide herbicides were irradiated with the intent of identifying the extent of monochloroacetic acid ( K A ) production.Conversion OF rnetolachlor to MCA as a result of photolysis increased from 5% during direct photolysis to near 30% conversion during indirect photolysis in a synthetic field water matrix.The photodegradation of aiachlor, butachior and a rnodel chIoroacetanilide.2-chloro-iVmethylacetanilide in SFW was also investigated.An investigation involving Buoroanilims (FAs) was conducted with the intent of identifying monofluoroacetic acid (MFA) as a photoproduct.Direct and indirect photolysis revealed the photoproduction of fluoride fiom ?-FA.3-FA.2.4-FA and 3.6-FA.aminophcnol from 3-FA and fluoronitrobenzene isomers for each of 2-FA.4-FA, 2.4-FA and 2.6-FA.Conversion to photoproducts varied with direct vs. indirect photolysis.MFA was not identiiied as a photoproduct of the Buoroanilines.The photodegradation of flumetsularn, flampropmethyl and ciprofloxacin were dso investigated.This work is dedicated to Ken. my best fnend and better half whose courage and strength keep me in constant love and admiration.

Full frame distilled prediction

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.
