Metastability is observed when a physical system is close to a first order phase transition. In this paper the metastable behavior of a two state reversible probabilistic cellular automaton with self–interaction is discussed. Depending on the self–interaction, competing metastable states arise and a behavior very similar to that of the three state Blume–Capel spin model is found.

We show that the $d$-dimen\-sion\-al Blume-Emery-Griffiths model has a unique Gibbs state, for all temperature, in some portion of disordered region parameters, ruling out possibility reentrant behavior same

We obtained genetic information on sexual reproduction of the Closterium peracerosum-strigosum-littorale complex, a unicellular charophycean alga. Normalized cDNA libraries were constructed from cells in the sexual reproduction process, and a total of 1190 5'-end expressed sequence tags were established. Since 604 of these ESTs were classified into 174 non-redundant sequences, these 1190 ESTs i...

Abstract HPLC (high-performance liquid chromatography) is one of the accurate chromatographic techniques that widely used for analysis. This present review submitted extraction and methods determining compound in Melastomataceae Asteraceae families related with insecticidal compounds. discusses standard conditions. There are several species under both families. As family, Melastoma malabathricu...

Our interest lies in exploring the ability of a coupled nonlocal system two quasilinear parabolic partial differential equations to produce phase separation patterns. The obtained patterns are referred here as morphologies. target is derived literature rigorous hydrodynamic limit suitably scaled interacting particle Blume--Capel--type driven by Kawasaki dynamics. describes rather implicit way i...

Wetting may occur when three or more phases (A, B, C,...) coexist. It consists of the appearance of a thick (macroscopic) layer of the C phase at an interface between the A and the B phases. This phenomenon has been observed experimentally and in computer simulation (for a review, see Ref. 1). It has also been investigated by mean field theory ~2 4) and by lowtemperature expansions. (s'6) In th...
