We present a simple mean value analysis (MVA) framework for analyzing the effect of scheduling within queues in classical asymmetric polling systems with gated or exhaustive service. Scheduling in polling systems finds many applications in computer and communication systems. Our framework leads not only to unification but also to extension of the literature studying scheduling in polling system...

BACKGROUND Increased left atrial (LA) size is a prognostic marker of mortality in the general population. LA size varies considerably in patients with dilated cardiomyopathy (DCM), but its clinical significance has not been widely studied. OBJECTIVE To evaluate the long-term prognostic value of LA volume (LAV) in patients with DCM. METHODS We prospectively studied patients admitted from Jan...

We consider systems of tandem blocking queues having a common retrial queue. The model represents dynamics of short TCP transfers in the Internet. Analytical results are available only for a specific example with two queues in tandem. We propose approximation procedures involving simple analytic expressions, based on mean value analysis (MVA) and on fixed point approach (FPA). The mean sojourn ...

This study tests the hypothesis that market value added (MVA) is more highly associated with stock return (SR) than traditional performance measures. The purpose of this study is to provide empirical evidence on the relative and incremental information content of MVA and traditional performance measures, namely, net income (NI), net operational profit after tax (NOPAT), and earning per shares (...

Respiratory diseases are multifactorial heterogeneous diseases that have proved recalcitrant to understanding using focused molecular techniques. This trend has led to the rise of 'omics approaches (e.g., transcriptomics, proteomics) and subsequent acquisition of large-scale datasets consisting of multiple variables. In 'omics technology-based investigations, discrepancies between the number of...

Industrialization is required to increase an economy's competitiveness and living standards, as well catch up more developed economies; while low lower-middle-income countries' average performance over the last five decades has been disappointing at 6.7 17.4%, respectively. Fabrication exports account for 37.1% of total low-middle-income 9.6% income. As a result, this article's main...
