متن کاملLattice-gas model for collective biological motion.
One of the most interesting aspects of evolution is the emergence of multicellular organisms due to the appearance of cooperation and differentiation of eucariotes. Although much research has been done along this line, some of the related basic questions are still open. As a natural step towards the understanding of the physical and physicochemical background of self-organization of microorgani...
متن کاملCooperativity in biological systems
Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...
متن کاملCollective circular motion of multi-vehicle systems
This paper addresses a collective motion problem for a multi-agent system composed of nonholonomic vehicles. The aim of the vehicles is to achieve circular motion around a virtual reference beacon. A control law is proposed, which guarantees global asymptotic stability of the circular motion with a prescribed direction of rotation, in the case of a single vehicle. Equilibrium configurations of ...
متن کاملMotion Apparent Diffusion in Biological Systems
This work describes the basics of diffusion measurement in biological systems. The first portion is dedicated to providing an understandable, classical-mechanical description of the Stejskal ] Tanner pulse sequence to give the reader an intuitive understanding of the measurement. This is followed by a description of the various aspects of water motion in biological systems that should be taken ...
