Amplified Biochemical Oscillations in Cellular Systems

Amplified biochemical oscillations in cellular systems

We describe a mechanism for pronounced biochemical oscillations, relevant to microscopic systems, such as the intracellular environment. This mechanism operates for reaction schemes which, when modeled using deterministic rate equations, fail to exhibit oscillations for any values of rate constants. The mechanism relies on amplification of the underlying stochasticity of reaction kinetics withi...

Secure Communication in Shotgun Cellular Systems

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

Cellular Automata Modeling of Complex Biochemical Systems

The role of a scientist is to study nature and to attempt to unlock her secrets. In order to pursue this goal, a certain process is usually followed, normally starting with observations. The scientist observes some part of the natural world and attempts to find patterns in the behaviors observed. These patterns, when they are found in what may be a quite complicated set of events, are then call...

MP Systems Approaches to Biochemical Dynamics: Biological Rhythms and Oscillations

Metabolic P systems are a special class of P systems which seem to be adequate for expressing biological phenomena related to metabolism and signaling transduction in biological systems. We give the basic motivation for their introduction and some ideas about their applicability to some basic biological oscillators.
