Optimal control of spiral waves in heterogeneous excitable media: non-monotonic efficacy of localized optogenetic inhibition

Structural heterogeneity stabilizes spiral waves in excitable media, yet how its spatial architecture, ranging from diffuse interstitial deposition to focal scar patterns, modulates the efficacy of localized optogenetic control remains poorly understood. Using a two-dimensional c...

Potato Planting Quality Detection and Reseeding System Based on Lightweight Detection and Multi-Frame Decision Making

Automatic reseeding in spoon-chain potato planters requires reliable classification of miss-seeding, normal, and multiple-seeding events. Oblique viewing and continuous spoon motion cause scale changes, boundary truncation, blur, and occlusion, which destabilize single-frame pred...

Advances in Technologies and Equipment for Potato Seed-Metering Quality Detection and Reseeding

Fast and accurate detection of missed and multiple seeding, followed by timely correction, is needed to maintain potato planting quality. Photoelectric, laser, capacitive, and machine vision methods have been developed for defect detection. Backup metering channels, catch-up comp...
