"A stochastic hybrid system (SHS) is a dynamic system that exhibits both a continuous and\r\na discrete dynamical behavior. In the scientific literature on SHS the principle of causality\r\nis commonly assumed, but more realistic models should account on history dependence. In\r\nthis thesis we developed and analyze a new mathematical model called Hereditary Stochastic\r\nHybrid System which, with the help of a generalization of stochastic time change, allows for\r\ngeneral history dependence. We apply the above model to the study of the movement of the\r\nbacterium E. coli: when these bacteria swim in a field of chemoattractant molecules, they\r\nperform a random walk characterized by a run-and-tumble motion. This random walk is\r\nbiased towards regions of higher concentration of the chemoattractant. These bacteria are,\r\nhowever too small to sense spatial gradients along their body axis. Instead they developed\r\na history-dependent strategy to search of food, namely the use of memory of previous mea-\r\nsurements of chemical concentrations. In this way the bacteria are able to infer whether they\r\nswim up or down a chemical gradient. By using our framework we are able to generalize the\r\nexisting models for E. coli movement and have a better fitting of the experimental data. We\r\ndeveloped also a software that simulates and compares the different models existing in the\r\nliterature, with special care for high performance and usability."^^ . "2018" . . . . . . .
