Tel Aviv University Dear all, The last meeting of the year for the Horowitz seminar on Probability, Ergodic Theory and Dynamical Systems will be held this Monday. Come celebrate with us! Speaker: Isaac Meilijson, Tel Aviv University Title: Granule membranes play dice Date: Monday, June 6 Time: 14:30 Place: Schreiber 209 NOTE SPECIAL ROOM!!! Abstract: Granules are secreted by the cell in either spontaneous or evoked mode, and the distribution of their volume is recorded, which we have modeled respectively as the exit and stationary distributions of a Growth & Elimination Markovian stochastic model. Growth requires granule-granule fusion and elimination requires granule-membrane fusion, by linking SNARE protein pairs diffusing in the granule and membrane surfaces. Transition rates of the Growth & Elimination model depend on the required number of such pairs for fusion, that can be identified (theoretically and experimentally estimated) from the two secretion volume distributions. Based on joint work with Ilan Hammel and Eyal Nitzany.
