Two main transitions may take place during the formation of a polymer network gelation, a critical transition defined by the conversion at which the mass-average molar mass becomes infinite (Chapter 3) glass transition, or vitrification, characterized by the conversion at which the polymer begins to exhibit the typical properties of a glass. 

Equation (33) means also that spectroscopic terms (energy levels) can be assigned to the product functions and the transitions defined between them have well determined energies (Figure 6). These transitions define the precession frequency of the corresponding single quantum coherences. 

In order to deal with a chemical reaction it is convenient to express the energy U by the perturbed Hamiltonian matrix as a function of the reaction coordinates t). Expressing the nuclear coordinates of the quantum center (we consider it as the solute or a part of the solute) as r = xq, t, f where xq are the internal quantum vibrational coordinates, t) the reaction coordinates (belonging to the solute classical internal coordinates Xjn) and the remaining classical coordinates. Defining with all the solute classical internal coordinates except t, i.e., Xjn =, tt, we have that the free-energy change for a chemical transition defined by %, is... 

Frank-Condon transition) define the potential energy surface. The meaning of the parameters is clear - energy stabilization due to the JT effect is given by the value of Ejy (or alternatively by E c = Eji), and direction and magnitude of the distortion by the Rjy.

A fictive temperature 7 based approach firstly introduced by Tool [47] has been proved to be extremely successful in supplying the information about the free volume or the structure in the formulation of the free energy density. The fictive temperature 7/ is an internal variable to characterize the actual thermodynamic state during the glass transition, defined as the temperature at which the temporary nonequilibrium stmcture at T is in equilibrium [20]. It was assumed that the rate change of the fictive temperature is proportional to its deviation from the actual temperature and the proportionality factor depends on both T and Tf [48], as indicated in the evolution equation [47] ...

Following the ideas of AndersonP l, Langton , who is one of the founders of artificial life research, coined the phrase life at the edge of chaos . To identify the condition of life for a cellular automaton system, he defined a control parameter A. For a cellular automaton with K states and N neighbors the A parameter is defined as follows. An arbitrary state Sq is chosen as a quiescent state, as for instance, the solution zero, with for the logistic map. If there are n, transitions defined to state Sq, the remaining...
