Cardiac electrophysiology is a rapidly expanding sub speciality of cardiology with ever increasing new information coming in every day, with quite a few journals devoted to it. Complexity of arrhythmias are sometimes puzzling for a busy cardiologist and so are electrophysiology studies. Electrophysiology for Clinicians is a concise book on basic concepts of cardiac electrophysiology for the bus...

This paper shows that in the G/M/1 queueing model, conditioning on a busy server, the age of the inter-arrival time and the number of customers in the queue are independent. Explicit expressions for the density functions of this age conditioning on a busy server and conditioning on an idle server are given. Moreover, we show that this independence property, which we prove by elementary argument...

Due to the effective role of Markov models in customer relationship management (CRM), there is a lack of comprehensive literature review which contains all related literatures. In this paper the focus is on academic databases to find all the articles that had been published in 2011 and earlier. One hundred articles were identified and reviewed to find direct relevance for applying Markov models...

In this paper we study the busy period in GI/G/1 work-conserving queues. We give the exact asymptotics of the tail distribution of the busy period under the light-tailed assumptions. We also study the workload process in the M/G/1 system conditioned to stay positive.
