We study the stochastic growth process in discrete time $x_{i+1} = (1 + \mu_i) x_i$ with rate $\mu_i \rho e^{Z_i - \frac12 var(Z_i)}$ proportional to exponential of an Ornstein-Uhlenbeck (O-U) $dZ_t \gamma Z_t dt \sigma dW_t$ sampled on a grid uniformly spaced times $\{t_i\}_{i=0}^n$ step $\tau$. Using large deviation theory methods we compute asymptotic (Lyapunov exponent) $\lambda \lim_{n\to ...

results the amount of hgbr2 (0.1% wt/vol) and cdso4 (0.2% wt/vol) were considered as lethal doses for l. monocytogenes ptcc 1297 (serotype 4a). different concentrations of pbo could not kill bacteria yet decreased their growth. the bacteria showed different morphologic and biochemical characteristics under each stressor. objectives the aim of this work was evaluate the growth, surface structure...
