ABSTRACT
Molecular systems are much closer to the quark than the jaguar in terms of complexity. This is the basis for an effective and classical approach to determining energy in atomic and molecular systems. The water molecules surrounding the molecule, the authors focus on exert an electric field on this molecule. Effective models can also be designed to account for complex spatial correlations between atoms. However, if chemical bonds are neither formed nor broken during the system’s evolution, the system can be modeled with an effective, purely classical model. More recently, effective force fields have even been able to account for the effects of chemical reactions through the definition of reactive force fields, in which functional forms model the bond breaking and forming. Signaling is a very general term encompassing communication processes in their broadest sense. Chemotaxis denotes the motion of an organism in response to a chemical stimulus, such as spatial gradients in the concentration of specific compounds.
