....process is a Markovian process in continuous time which is completely described by the transition rates, P ; 1 , P ; and P ; Gamma1 . The replicationdeletion process with the approximations adopted above, and with a finite population of constant size N , is a birth and death process [25, 35, 36] that converges to a stationary distribution, defined by: dP =dt = 0 8 . The time axis can be transformed such that the probability for a replication deletion event becomes independent of the population average. This reactor time t is defined by d t = dt (oe Gamma 1) N = dt ( ....

For our purposes it is sufficient to consider the time homogenous processes for which the infinitesimal parameters depend only on the state x and not on t. Following the procedure in [17], we now set the state 0 and the predefined overflow limit c as absorbing barriers. The problem is to find the probability of absorption into c when starting from the position X(0) x,0 x c. Denote this probability by u(x) and select a small time duration h,sosmall that the absorption ....

For the simplest model, we follow the example of Harrison and Patel [18] and shed light on a GI GI 1 queuing model with independent inter arrival time ....

....noise in the form of a Wiener or Gaussian process. The addition of random jumps and later Poisson processes became possible through the original work of theorists such as Florentin [ It6 [13] Kushner [16] and Gihman and Skorohod [8] and continued by people such as Karlin and Taylor [14], Ryan and Hanson [19] Marlton [18] and Westman and Hanson[20, 22] One general approach is to use stochastic dynamic programming, but this requires a large amount of memory. Large random jumps can be especially troublesome, even when finite elements are used, in part due to the Curse of ....

....v t v x v y is supposed to follow the stochastic infinitesimal equation (M1) dv t av t dt for positive constants a and b and a two dimensional Brownian motion W t . An introduction to SDEs can be found in [43] and an elegant treatment of one dimensional diffusions is given in [31]. The coefficient av t is called the infinitesimal drift and b the infinitesimal variance. Heuristically, a gives the rate at which the velocity regresses to zero and b gives the magnitude of the random innovations which tend to push the velocity away from zero. The root mean square speed ....

....of the bacterium up an increasing gradient of a ligand, and f : is a convex function, then the expected value E f x t is monotone increasing with time. This would also be true if x t were an unbiased random walk, or a martingale. Comparing the Ito and Stratonovich solutions [31] to the SDEs introduced in Section 3 gives a new insight into the controversy. Kinesis may be modeled in a simple but instructive way by considering a stochastic process x t , taking values in 0 , defined by the infinitesimal equation dx t sx t dW t This is a particular case of (M4) ....

....q distribution) on the set of vertices does not seem to be of simple nature and no substantial properties are known. Here we consider an extension of the second approach which is easily implementable by distributed algorithms. The idea is based on the assumptions linked to Poisson processes, see [4]. Each vertex which has become a leaf, has lifetime which is a real valued random variable exponentially distributed. The leaf is removed once its lifetime has expired (if the tree is not reduced at that time to a unique vertex) The process continues until the tree is reduced to a vertex; the ....

Once a vertex v has become a leaf, its death happens according to a Poisson process with a given parameter (v) which is supposed to have been determined by some speci c rules detailed in the sequel. Each leaf v of the residual tree behaves independently and, under the assumption that it is ....

For any ergodic Markov chain, the convergence of (n) a to a in Theorem 4 is also in the sense of l 1 . When the Markov chain P is ergodic, then 0 a 0;j = j according to Theorem 3. 3 of [8]. Using a similar argument (also see Remark 1) we can show that i a i;j = j .
