We propose a two-dimensional model of biochemical activation process. whereby self-propelling particles of finite correlation times are injected at the center of a circular cavity with constant rate equal to the inverse of their lifetime; activation is triggered when one such particle hits a receptor on the cavity boundary. modeled as a narrow pore. We numerically investigated this pr... https://ashleyshomestores.shop/product-category/outdoor-lounge-chair-with-cushion-set-of-2/
