In this report, we theoretically examine the responses of spiking neurons to spike sequences which obey an inhomogeneous Poisson process. When statistically independent random inputs are provided, the probability densities of membrane potential converge to Gaussian distribution. In this case, the stochastic process of the membrane potential becomes Gauss process. We introduce a calculation meth...

This study was conducted aiming to survey role of feeling of energy in relation of evolution leadership with staff contribute in work creativity. Statistical population was employees and staffs of Hier Company who were 525 persons (2009 summer). 332 employees were selected for contribution in the study by quota stratified sampling. Research instruments were 8-question feeling-of-energy question...

Semilinear stochastic evolution equations with multiplicative Poisson noise and monotone nonlinear drift in Hilbert spaces are considered‎. ‎The coefficients are assumed to have linear growth‎. ‎We do not impose coercivity conditions on coefficients‎. ‎A novel method of proof for establishing existence and uniqueness of the mild solution is proposed‎. ‎Examples on stochastic partial differentia...

In this paper, we consider a class of time-dependent neutral stochastic evolution equations with the infinite delay and a fractional Brownian motion in a Hilbert space. We establish the existence and uniqueness of mild solutions for these equations under non-Lipschitz conditions with Lipschitz conditions being considered as a special case. An example is provided to illustrate the theory

in this work, we successfully construct the new exact traveling wave solutions ofthe generalized sinh–gordon equation by new application of the homogeneousbalance method. the idea introduced in this paper can be applied to othernonlinear evolution equations.
