We present numerical and analytical results for a special kind of one-dimensional probabilistic cellular automaton, the so called Domany-Kinzel automaton. It is shown that the phase boundary separating the active and the recently found chaotic phase exhibits reentrant behavior. Furthermore exact results for the p 2 =0-line are discussed.

Abstract. A coagulation-decoagulation model is introduced on a chain of length L with open boundary. The model consists of one species of particles which diffuse, coagulate and decoagulate preferentially in the leftward direction. They are also injected and extracted from the left boundary with different rates. We will show that on a specific plane in the space of parameters, the steady state w...

an analytical model for a coastal boundary current was used to investigate heat and salt budget of exchange flows in the persian gulf as a marginal sea. coastal boundary currents exchange heat and freshwater with the mosphere and the offshore waters. as heat and salinity fluxes caused by air-sea interaction and eddy activities, different temperature and salinity associated with boundary current...

The homologous recombination between direct repeat sequences separated by either 200 or 1000 bp was induced by active transcription of the downstream gene when poly(dG)-poly(dC) sequences exist between the two direct repeats. This dG tract-mediated and transcription-induced recombination was RecA independent, and the frequency of recombination was dependent on both the length and the orientatio...

We study the behavior of several physical properties of the Haldane model as the system undergoes its transition from the normal-insulator to the Chern-insulator phase. We find that the density matrix has exponential decay in both insulating phases, while having a power-law decay, more characteristic of a metallic system, precisely at the phase boundary. The total spread of the maximally locali...

This paper reports new data on the distribution of grain boundary planes in commercially available GBE copper. The results show that nearly 60% of grain boundary length was Σ3, i.e. annealing twin related. There was a slightly enhanced proportion of {111} boundary planes, even after Σ3 boundary segments were excluded from the data set. There was a high proportion of boundary plane length on the...

Direct observation of electric potential and field variation near local scatterers like grain boundaries, triple points and voids in thin platinum films studied by scanning tunneling potentiometry is presented. The field is highest at a void, followed by a triple point and a grain boundary. The local field near a void can even be four orders of magnitude higher than the macroscopic field. This ...

In this paper, we investigate the thermodynamics of D-dimensional charged Gauss-Bonnet black holes in anti-de Sitter spacetime. By considering variations cosmological constant, Newton's constant and coupling bulk, one can rewrite first law a holographic form, where contributions thermodynamical variables bulk boundary field theory are both included. Based on approach, study phase transition cen...
