Important aspects in information theory and control theory appeared by studying the behaviour of biological systems. The classical control loop is a good example presenting the methods used by biological entities for controlling certain functional parameters in different circumstances. The further development of control theory and of dynamical models led to important achievements in the study of evolutionary processes. However, some modern aspects in physics (quantum theory) and mathematics (wavelets, fractal theory) imply a more profound approach of transitions and short range phenomena both in materials science and in natural (biological) systems.
The mathematical formalism of Impulsive Systems tries to use the rigorous aspects from Continuous Systems formalism and the wide range of applications of Discrete Systems formalism also. They were introduced due to the fact that many evolution processes are characterized by the fact that at certain moments of time they are subject to short-term perturbations (having the form of external impulses). It is known, for example, that many biological phenomena involving thresholds, bursting rhythm models in medicine and biology, optimal control models in economics, frequency modulated systems present impulsive effects. Thus impulsive differential equations, (involving impulse effects) can describe evolution of many scientific and technical phenomena.
Yet the study of such abrupt changes must be completed with logical, mathematical and technical aspects connected with the moment of action of such impulsive external commands.
For modelling such changes (transitions) in an accurate manner, specific dynamics on limited time interval is required. It must be taken into account the fact that bioinformatics should join together both statistical aspects (well known in natural sciences from thermodynamics theory and quantum theory) and deterministic aspects (descrobing the evolution of systems by differential equations, similar to classical mechanics). As a particular aspects for biological systems, aspects connected with the so-called free-choice (for human systems0 and external intervention (for human and biological systems) should be added . This implies the use of an accurate dynamics of perturbations, intervention and transition in multi-scale systems, so as deterministic aspects and stochastic aspects to be merged into an unitary model of the Proper Time of Intervention. (a very useful concept for human action).
The Workshop Dynamical Aspects of Perturbation, Intervention and Transition in Biological Systems is intended to emphasize the necessity of joining together deterministic and stochastic methods in an accurate multi-scale approach for modelling perurbations, transitions and interventions in biological systems.
