Reaction-Driven Membrane Systems

چکیده
Membrane systems are gaining a prominent role in the modeling of biochemical processes and cellular dynamics. We associate specific reactivity values to the production rules in a way to be able to tune their rewriting activity, according to the kinetic and state-dependent parameters of the physical system. We come up with an algorithm that exhibits a good degree of versatility, meanwhile it gives an answer to the problem of representing oscillatory biological and biochemical phenomena, so far mostly treated with differential mathematical tools, by means of symbolic rewriting. Results from simulations of the Lotka-Volterra’s predator-prey population dynamics envision application of this algorithm in biochemical dynamics of interest.

متن کاملInfluence of Membrane Sealing in Pressure-Driven Test Cells on Their Performance
This communication demonstrates the relevance of membrane sealing in a test cell to its performance. Membranes need to be sealed, and therefore a more or less signifcant (depending on the test cell design) peripheral part of the membrane is supported directly by the cell body (instead of a permeate spacer). Although it may seem that there should be no fltration through ...
متن کاملEffect of Complexation Reaction Constant on the Separation of Propylene/Propane by Supported Liquid Membrane
Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibriu...

Membrane filtration, especially based on the size exclusion phenomenon, has long been established due to its abilities to addressing the growing demands of the clean water of the world’s population. However, widespread applications of the membranes face several challenges including chemical vulnerability, thermal deterioration, and biological degradation of the membranes that transpire while re...
متن کاملTime-Driven Computations in P Systems
It is a well-known fact that the time of execution of a (biochemical) reaction depends on many factors, and, in particular, on the current situation of the whole system. With this motivation in mind, we propose a model of computation based on membrane systems where the various rewriting rules have different times of execution and, moreover, the time of execution of each rule can vary during the...
متن کاملGABA-mediated membrane oscillations as coincidence detectors for enhancing synaptic efficacy in the developing hippocampus
Spontaneously occurring neuronal oscillations constitute a hallmark of developmental networks. They have been observed in the retina, neocortex, hippocampus, thalamus and spinal cord. In the immature hippocampus the so-called ‘giant depolarizing potentials’ (GDPs) are network-driven membrane oscillations characterized by recurrent membrane depolarization with superimposed fast action potentials...
