Cellular automata are collections of cells arranged in some manner such that each cell contains a value that is updated from generation to generation according to a local rule. The Game of Life [1-5,7,15] is perhaps the best known cellular automaton. It is based upon a rectangular arrangement of cells that are either 0 or 1, along with simple rules of evolution: if a cell is 0 and has exactly 3...

We employ the statistical reactions with memory approach to study oscillating excitation functions in the Si(Elab = 120 − 126.75 MeV)+64Ni strongly dissipative reaction and the time evolution of the collision process. The nonself-averaging of the oscillations in the excitation functions is interpreted as indication of quantum chaos and damping of the coherent nuclear rotation in dissipative hea...

“Oscillations and Dynamic Instabilities in Chemical Systems” is the title of the Gordon Research Conference inaugurated in 1982 by Irving R. Epstein, whom we honor with this Focus Issue. Oscillations and dynamic instabilities in chemical systems comprise the study of dynamical phenomena in chemically reacting systems far from equilibrium. Systematic exploration of this area began with investiga...

Chemically oscillating reactions are abiotic that produce characteristic, periodic patterns during the oxidation of carboxylic acids. They have been proposed to occur early diagenesis sediments contain organic matter and partly explain some enigmatic spheroids in malachite, phosphorite, jasper chert, stromatolitic chert from rock record. In this work, circularly concentric self-similar shown fo...

Polymerase chain reactions (PCR), thermally activated chemical reactions which are widely used for nucleic acid amplification, have recently received much attention in microelectromechanical systems and micro total analysis systems because a wide variety of DNA/RNA molecules can be enriched by PCR for further analyses. In the present work, a droplet-based micro oscillating-flow PCR chip was des...

The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...

Belousov–Zhabotinsky (BZ) reactions have been used to investigate periodic spatial patterns due the oscillatory nature of reaction. However, these systems not confined, nor controlled, in macro-scaled architectures, making it hard translate observations natural behavior. Here, a poly(electrolyte) complex is designed that can be ionically or covalently reinforced construct 3D geometries with add...

QCD predictions for moments of parton multiplicity distributions are discussed. The next-to-leading terms and conservation law give rise to the peculiar oscillating shape of some ratio of the moments. The similar shape has been found by moment analysis of hadron multiplicities. Experimental data, theoretical Monte Carlo models and phenomenological fits have been used for ee, hh, hA, AA reaction...

Relaxation processes in proteins range in time from picoseconds to seconds. Correspondingly, biological electron transfer (ET) could be controlled by slow protein relaxation. We used the Langevin stochastic approach to describe this type of ET dynamics. Two different types of kinetic behavior were revealed, namely: oscillating ET (that could occur at picoseconds) and monotonically relaxing ET. ...
