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://www.diegojavierfares.com/best-price-Electro-Mech-LX174-Ten-Inning-Baseball-Scoreboards-special-buy/
