We derive an upper bound for the largest Lyapunov exponent of a Markovian product of nonnegative matrices using Markovian type counting arguments. The bound is expressed as the maximum of a nonlinearâ€¦ (More)

We consider partially asynchronous parallel iteration of a fixed nonnegative matrix with stationary ergodic interprocessor communication delays. We study the iteration via a random graph describingâ€¦ (More)

The parameters characterizing the quenching of fluorescence emitted by the four tryptophans of actin were measured by time resolved techniques in the monomeric (G) and the polymerized (F) forms ofâ€¦ (More)

Abst ract. We consider monotonic binary cellular automa ta on the lat tice ZP as models of systems capable of long-term memory, that is, capable of admitting multiple invariant configurat ions.â€¦ (More)
