Phase Locking in the Oscillations Leading to Turbulence
The transition to turbulence often occurs through one or more hydrodynamic instabilities, each characterized by the onset of a qualitatively distinct type of time dependence as a dimensionless parameter is var...

Electrical Effects in Nonlinear Physico-Chemical Systems: Field Chemical Wave Interaction and Bio-Self Electrophoresis
The presence of membrane potentials in electrophysiological systems is shown to be capable of profoundly influencing the course of biomorphogenesis. We focus on the problem of self organization in the egg of Fucu...

Chaos and Its Description
There may be various different physical origins for the phenomenon called “fluctuation”. Here, however, we confine ourselves to those fluctuations for which the best possible description is a stochastic one. F...

The Oscillatory Basis of Cell Energy Metabolism
The aim of this paper is to outline a proof that long-period sustained oscillations are necessary for precise stabilization of ATP concentration by cell energy metabolism.

Non-Uniform Stable Solutions to Reaction-Diffusion Equations: Applications to Ecological Pattern Formation
In the mathematical theory of ecological communities, there are two major subjects: (i) the temporal dynamics of interacting populations and (ii) the spatial pattern of the community. Historically, these subje...

Abduction of Semantic Patterns
In the study of regular structures the map**s between them play a central role, just as is the case in algebra in general. One there-fore examines homomorphisms, isomorphisms, and deformations between regula...

Systems and Changes of Systems in History
Historians speak relatively little about systems. Using this word ‘system’ they describe a social system as a group of persons in which the individual has different functions and in which individuals are conne...

Thermodynamics of Nonequilibrium Processes
Thermodynamics had its origins in the work of engineers at the beginning of the industrial revolution. People like Thompson and Carnot were concerned with practical questions concerning the lathing of cannon a...

Evolution of Systems. Time Scaling and Scaling Factors
Patterns may not be self-evident features of phenomena. It may even be said that some patterns exist only when they have been discovered, so that imagination is at the origin of a search for patterns: the obse...

Atomic Cooperation in Quantum Optics: Superfluorescence and Optical Bistability
Despite the fact that both Spectroscopy and Quantum Optics study the radiation-matter interaction, these two chapters of Physics present a fundamental difference. In fact, Spec troscopy considers those phenomena ...

Laser with Saturable Absorber. Fluctuations and Stability
The development of laser theory has focused recently much of interest on the general description of instabilities in systems far from thermal equilibrium. It is well recognized now a-days that in physics, biop...

A Theory of Drug Induced Visual Hallucination Patterns
At the last synergetics workshop [1], one of us (JDC) discussed some aspects of signal processing in the vertebrate visual system in synergetic terms, i.e., in terms of the study of those cooperative interacti...

Laserlike Approach to the Dynamics of the Rayleigh-Bénard and the Soret-Driven Instabilities
The aim of this work is to discuss some recent theoretical results concerning the steady-state and the dynamics of both the Rayleigh-Bé nard instability (RBI) and the Soret-driven instability (SDI) [1].

Similarities Between Pattern Formation and Pattern Recognition (Interpretation) During Biological Development
The development of a higher organism begins from a more or less homogeneous egg. The final complexity of structures must be generated during its development. Differences between parts of a develo** system ca...

A Simplified Theory of Intermittent Fully-Developed Turbulence
Fully-developed turbulence consists of hierarchies of eddies of various sizes, where a small-scale eddy is generated from a larger eddy and disintegrates into smaller eddies of about the half-length size in a ...

Patterns in the Immune System
There is a hierarchy of four levels on which one may talk about patterns in the immune system. The highest level concerns the morphology of the entire organ. Important as its detailed design may be in reality,...

Recent Advances in Syntactic Pattern Recognition
The many different mathematical techniques used to solve pattern recognition problems may be grouped into two general approaches [1,2]. They are the decision-theoretic (or discriminant) approach and the syntac...

Socioeconomic Inequalities: Adaptation and Application of a Theory of Biological Pattern Formation
It is proposed that socioeconomic inequalities between individuals, subgroups or nations result to a considerable extent from a combination of self-enhancing and depletion effects which are counteracted by red...

Representation and Processing of Associations Using Vector Space Operations
Vector space operations, in particular orthogonal projection operations have been extensively used in estimation theory and the optimal control of dynamic processes. It seems that they apply to the processing ...

Bifurcation and Nonlinear Focusing
We suggest that the phenomenon of nonlinear focusing can play an important role in the transition of a system from one wavelike state to another.
