Abstract:The interaction functions of electrically coupled Hindmarsh-Rose (HR) neurons for different firing patterns are investigated in this paper. By applying the phase reduction technique, the burst phase response curve (BPRC) of the bursting neuron is derived. Then the interaction function of two coupled neurons can be calculated numerically according to the BPRC and the voltage time course of the neuron. Results show that the BPRC is more and more complicated with the increase of the spiking number within a burst, and the curve of the interaction function oscillates more and more frequently with it. However, two certain things are unchanged: $phi=0$, which corresponds to the in-phase synchronization state, is always the stable equilibrium, while the anti-phase synchronization state with $phi=0.5$ is an unstable equilibrium. | |||

Abstract:In this paper, burst synchronization of a small-world neuronal network consisting of mixed bursting types of neurons coupled via inhibitory-excitatory chemical synapses is explored. The quantities, the synchronization parameter, is used to characterize the synchronization degree of the neuronal network. Numerical results show that the percentage of the inhibitory synapses in the network is the major factor for we get a similarly bell-shaped dependence of synchronization on it. We also find that not only the value of the coupling strength can promote the synchronization degree, but also the probability of random edges adding to the small-world network can. The ratio of the long bursting neurons has little effect on the burst synchronization of the network. | |||

Abstract:For the nonlinear and dispersive long gravity waves traveling in twohorizontal directions with varying depth of the water, we consider avariant Boussinesq with variable coefficients (vcvB) system withsymbolic computation. Using the Darboux transformationof the vcAKNS system, we present the double Wronskian-type solutionfor the vcvB system. Two sorts of inelastic interactions for thevcvB system are graphically discussed. | |||

Abstract:The Mickens iteration method is modified for solving limit cycle oscillations (LCOs) of self-excited systems. Different from other existing procedures, the unknown frequency that arises in the nonlinearity is replaced by the previous iteration value. Therefore, the unknown frequency appears just in linear terms and its square can be considered as an independent parameter. Simpler algebraic equations are then deduced and solved numerically. Numerical examples show the modified algorithm can provide very accurate LC solutions. Since the unknown frequency is uncoupled from nonlinear terms, this approach is rather appropriate for a type of systems with nonlinear damping terms. | |||

Abstract:Referring to the central line of rod to establish local dragging coordinator system, the S+R decomposition of deformation tensor is used to obtain the two sets of non-linear motion equations of rod with large deformation. One set is about the central line, another set is out-central line regions. For simple bending and simple torsion, simplifed non-linear motion equations are obtained. The research shows that: 1) for sharp bending, the exact motion equations for elastic line is obtained; 2) for simple torsion, the intrinsic stretching along the rotation direction is indispensable. This is the main distinction between rigid rotation and the local whole rotation in continuum; 3) when the local rotation angle is big enough, the deformation will jump to the another kind of formation form; 4) the S+R decomposition can be viewed as decomposing the general deformation into one torsion-free local stretching S and one deformation with torsion R. | |||

Abstract:The non-linear motion equations of deformation are open problem for rational mechanics. For this research, the deformation is defined as the base vector transformation of commoving dragging coordinator system in geometrical field theory. As a logic conclusion, the strain and stress is defined as mixture tensors with the lower index related with current configuration and the upper index related with initial configuration. In this research, after a simply review about the mixture stress tensor, the corresponding motion equations are introduced. Then, the S+R decomposition is used to simplify the non-linear motion equations. To compare the general motion equations obtained in this research with the well-known non-linear motion equations, the motion equations in curvature coordinator systems are derived from general equations, respectively. Finally, the strategy to solve the general motion equations for large deformation is discussed. | |||

Abstract:Under periodic boundary condition, dynamic bifurcation and stability in the modified Kuramoto- Sivashinsky equation with a higher-order nonlinearity are investigated by using center manifold reduction procedure. The result shows, as the control parameter crosses a critical value, the system undergoes a bifurcation from the trivial solution to produce a cycle consisting of locally asymptotically stable equilibrium points. Furthermore, for the distance from bifurcation small enough, one-order approximations to the bifurcation solutions are obtained. | |||

Abstract:In this work, through the three-point bending, the mechanical properties of metal honeycomb sandwich structure were analyzed theoretically under room and high temperature environment. The numerical simulations of this structure were carried with the finite element software. The simulation results were well agreed with the experiment results. The results show that the honeycomb sandwich structure which brazed by carbon steel under the three-bending experiments, the L direction specimen were 10% stronger than W direction specimen. The shear strength of honeycomb core was enhanced, but still satisfied the shear strength requirements. Then based on the method of equal rigidity, with the same length, width, and different equal height, the sandwich structure was equaled to a solid panel, and the honeycomb sandwich structure was lighter than the equivalent panel. Finally the optimization design of the metal honeycomb sandwich structure was accomplished by finite element analysis, under the premise of the strength and stiffness satisfied, the optimal solution of the weight was obtained. The minimum weight's geometry of the metal honeycomb sandwich structure was gained. | |||

Abstract:The method of Delays is commonly used in state space reconstruction of chaotic time series, and the quality of attractor reconstruction of phase space is sensitive to the choice of embedding parameters, i.e. embedding dimension and time delay. In this paper, a new information measure based on singular entropy (SE) is proposed to choose the optimal time delay in reconstructed dynamical system, which differs from the correlation function method by using singular value fraction (SVF). The robustness of singular entropy algorithm is further discussed, and it shows the advantage of the proposed method. | |||

Abstract:As an important model mathematically and physically, a non-isospectral and variable-coefficient modified Korteweg-de Vries (mKdV) equation is investigated in this paper. Starting from the Lax pair presented, the Bäcklund transformation in original variables is explicitly deduced. And then, by a dependent variable transformation, the non-isospectral and variable-coefficient mKdV equation is transformed into bilinear equations, by virtue of which the N-soliton-like solution is obtained. Subsequently, through the bilinear Bäcklund transformation gained, the one-soliton-like solution is derived from a vacuum one. Furthermore, the N-soliton-like solution in the Wronskian form is constructed and verified via the Wronskian technique. | |||
