• Identical synchronization in complete network of ordinary differential equations of fitzhugh-nagumoIdentical synchronization in complete network of ordinary differential equations of fitzhugh-nagumo

    Abstract: Synchronization is a ubiquitous feature in many natural systems and nonlinear science. In this paper, the synchronization in complete network consisting of n nodes is studied. Each node is connected to all other nodes by linear coupling and it is represented by a system of ordinary differential equations of FitzHugh-Nagumo type which i...

  • Novel exponential stability criterion of nonlinear systems with interval time-varying delaysNovel exponential stability criterion of nonlinear systems with interval time-varying delays

    Abstract: This paper presents a new result on delay-dependent exponential stability for nonlinear linear systems with interval time-varying delay. By constructing a set of improved Lyapunov-Krasovskii functionals combined with Wirtinger-based integral inequality, a new delay-dependent condition is established in terms of linear matrix inequality...

  • Global attractors of nonlocal reaction diffusion equations with exponential nonlinearitiesGlobal attractors of nonlocal reaction diffusion equations with exponential nonlinearities

    Abstract: In this paper, we investigate the existence, uniqueness, and continuity of weak solutions with respect to initial values for a nonlinear parabolic equation of reactiondiffusion nonlocal type by an application of the Faedo-Galerkin approximation and AubinLions- Simon compactness results. The nonlocal quantity appears in the diffusion coef...

  • Nursery conditions for oncidium (Sweet sugar) growth and development at seedling and adult stagesNursery conditions for oncidium (Sweet sugar) growth and development at seedling and adult stages

    Abstract: Viet Nam is a tropical country with monsoons, which is suitable for growing different kinds of flowers including Oncidium-sweet sugar Orchids. Production of Orchids in Viet Nam has not fully developed, compared with the potentials of this kind of flowers due to a lack of appropriate process of technology to produce Orchids. Research on...

    Abstract: Consider an ideal gas system consisting of a large number of particles. The nature of the macroscopic system could not be described in detail. It could only be described in terms of averages, i.e. only the mean values of the thermodynamic quantities characteristic of the medium of the macro system. The average values of the thermodynam...

  • Determined conditions of laser field on acoustic phonon increasing in semiconductor blockDetermined conditions of laser field on acoustic phonon increasing in semiconductor block

    1. Introduction Phonon amplification by absorption of laser field energy is a subject extensively investigated in different structures [1,2,3,4,8]. The main results of these papers are that by absorption of laser field energy, the interaction of the laser field with electron can lead to the excitation of higher harmonics and the amplification o...

  • Some main occurrences of crossed modulesSome main occurrences of crossed modules

    1. Introduction Crossed modules (over groups) were invented almost 70 years ago by J. H. C. Whitehead in his work on combinatorial homotopy theory [10]. Whitehead's ideas on crossed modules and their applications were developed and explained in the book by R. Brown, P. J. Higgins, R. Sivera [1]. Some generalisations of the idea of crossed modul...

    Abstract: Semi-synthesized products derived from natural compounds currently play an important role in the research and finding new substances. Allobetulin, obtained through a process of transformation from betulin, is compound extracted from the birch trees, could be used as the starting material for some transformation reactions. Some new deri...
