Ferroin-Induced Complex Oscillations in the Bromate−Hydroquinone Photochemical Reaction
Bibliographic record
Abstract
This study presents an experimental investigation on the dynamics of the ferroin-bromate-hydroquinone photoreaction, in which two isolated oscillatory regimes emerge due to the presence of ferroin. Oscillations within the two isolated regimes exhibit different dependence on light intensity and initial compositions of the reaction solution. A phase diagram outlining the occurrence of the new oscillatory regime has been established in the bromate-ferroin concentration plane. As opposed to the ferroin-free system, in which there is nearly no difference in the reaction behavior whether benzoquinone or hydroquinone is used as the starting reactant, here the two-staged oscillatory behavior can only be obtained with hydroquinone as the initial reagent. This observation suggests that the reduction of ferriin by hydroquinone and the autocatalytic oxidation of ferroin by acidic bromate may have played a major role in the new oscillation window.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
