Cover Story: One of the most important applications of graph theory is the study of metabolic networks, i.e., those networks in which occurs the transformation of one or several molecules into one or several final products. In living organisms, metabolic network evolution is explained by assuming the independent evolution of the enzymes involved in the isolated biochemical reactions. In this paper, we present a simulation model in which enzymes, the real drivers of metabolism, are modeled as automata simulating their evolution with a genetic algorithm. The results obtained not only give clues about the evolution of metabolic pathways in organisms, but also introduce a new approach to simulating the evolution of other complex networks. View this paper

Mathematical Modeling of Multi-Phase Filtration in a Deformable Porous Medium

  • V. F. Burnashev,
  • K. K. Viswanathan and
  • Z. D. Kaytarov

In this paper, a mathematical model of multiphase filtration in a deformable porous medium is presented. Based on the proposed model, the influence of the deformation of a porous medium on the filtration processes is studied. Numerical calculations a...
