The attractivity of nonlinear differential equations with time delays and impulsive effects is discussed. We obtain some criteria to determine the attracting set and attracting basin of the impulsive delay system by developing an impulsive delay differential inequality and introducing the concept of nonlinear measure. Examples and their simulations illustrate the effectiveness of the results an...

The impulsive noise is the main cause of packet errors in power line communication networks. In this paper, the bit error rate (BER) and medium access control (MAC) protocol analytical models under impulsive noise interference are developed. The accuracy of the developed models is verified by computer simulations. In the computer simulations, the Poisson arrival of the impulsive noise is simula...

background: studies show that vestibular rehabilitation is an important option in the treatment bppv that is common in elderly. the purpose of this study was to analyze the effect of epley maneuver on vertigo symptoms in elderly patients with benign paroxysmal positional vertigo. methods: this cross-sectional-analytic study was performed from may 2007 to february 2010 on 67 patients (29 female,...

in this paper, global robust stability of stochastic impulsive recurrent neural networks with time-varyingdelays which are represented by the takagi-sugeno (t-s) fuzzy models is considered. a novel linear matrix inequality (lmi)-based stability criterion is obtained by using lyapunov functional theory to guarantee the asymptotic stability of uncertain fuzzy stochastic impulsive recurrent neural...

Risky sexual behavior (RSB) is associated with a variety of negative health and social consequences including STDs and unplanned pregnancies. The present study focused on the association between psychopathic personality traits and RSB. College students (N = 511) completed self-report measures of RSB, psychopathic personality traits, and sensation seeking. When sensation seeking, Fearless Domina...

The purpose of this paper is to present the fundamental concepts of the basic theory for linear impulsive systems on time scales. First, we introduce the transition matrix for linear impulsive dynamic systems on time scales and we establish some properties of them. Second, we prove the existence and uniqueness of solutions for linear impulsive dynamic systems on time scales. Also we give some s...

In this paper, impulsive control and synchronization for the newly presented Lorenz systems family are systematically investigated. Some new and more comprehensive criteria for global exponential stability and asymptotical stability of impulsively controlled Lorenz systems family are established with varying impulsive intervals. In particular, several simple and easily verified criteria are der...

In this paper, we consider a class of impulsive stochastic Volterra-Levin equations. By establishing a new integral inequality, some sufficient conditions for the existence and global attractivity of periodic solution for impulsive stochastic Volterra-Levin equations are given. Our results imply that under the appropriate linear periodic impulsive perturbations, the impulsive stochastic Volterr...

BACKGROUND The relationship between impulsivity and suicide has been conceptualized in the literature as a direct one. In contrast, Joiner's [Joiner, T.E., 2005. Why people die by suicide. Harvard University Press, Cambridge, MA.] theory posits that this relationship is indirect in that impulsive individuals are more likely to engage in suicidal behavior because impulsivity makes one more likel...
