We establish heavy traffic limit theorems for queue-length processes in critically loaded single class queueing networks with state dependent arrival and service rates. A distinguishing feature of our model is non-Markovian state dependence. The limit stochastic process is a continuous-path reflected process on the nonnegative orthant. We give an application to generalised Jackson networks with...

This paper presents a simple model of wage bargaining and employment ows designed to address the e ects of policies to increase the rate of exit to employment of the long-term unemployed. Exit rates from long and short-term unemployment have two e ects on the unemployment rate: a positive one as high exit rates strengthen current employees' bargaining positions and thus wages and a negative one...

the capability of sand constitutive models is remarkably improved by taking into account the effect of soil state in their formulations. in this study, it has been shown that considering the effect of soil state leads to better simulation of soil instability of shear banding type. to this aim, constitutive equations of a state dependent sand model are explained first. consequently, the general ...

In the present study, the effects of morphine sensitization on morphine-induced impairment of memory formation and the state-dependent retrieval of a passive avoidance task learned under morphine influence have been investigated in mice. Pre-training administration of morphine (0.5, 2.5 and 5 mg/kg) dose dependently suppressed the learning of one-trial passive avoidance task. Pre-test administr...

In this article, the problem of time-dependent stress redistribution of a piezomagnetic rotating thick-walled cylinder under an axisymmetric hygro-thermo-magneto-electro-mechanical loading is analyzed analytically for the condition of plane strain. Using the constitutive equations, a differential equation is found in which there are creep strains. Primarily, eliminating creep strains, an analyt...

Introduction: There are many similarities between memory impairment in patients suffering from Alzheimer and animals treated by Cannabinoids. The agonists of Cannabinoid receptors affect on a variety of memories and leanings. The present study aims to investigate the role of α-1-adrenergic receptors in central region of amygdala in state-dependent learning induced by WIN55,212-2 (cannabin...
