Abstract
In this study, we report the observation of oscillatory clusters in the photosensitive Belousov–Zhabotinsky reaction switching between excitable and unexcitable states. Numerical studies with a three-variable Oregonator model have been carried out in one- and two-dimensional media. Both non-flux and periodic boundaries have been characterized. Two- and three-phase clusters with standing, breathing, and irregular segregations are achieved when the intensity and durations of the two phases of the square-wave forcing are varied. The occurrence of oscillatory clusters in the excitable medium is due to the dual functions of the inhibitory light perturbation, i.e. eliminating existing wave activity as observed in earlier studies and initiating pattern formation at unexcited regions. The unusual positive impact of the inhibitory perturbation is analyzed, based on the flow trajectories of the system in a two-dimensional concentration phase plane.

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 it
