In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...

It has been proposed that cholesterol in host cell membranes plays a pivotal role for cell entry of HIV. However, it remains largely unknown why virions prefer cholesterol-rich heterogeneous membranes to uniformly fluid membranes for membrane fusion. Using giant plasma membrane vesicles containing cholesterol-rich ordered and cholesterol-poor fluid lipid domains, we demonstrate that the HIV rec...

In this paper we examine a database assembled from an Australian public register of 553 merger decisions taken between March 2004 and July 2008. Mergers may be accepted without public assessment, accepted in conjunction with publication of a Public Competition Assessment, or rejected. We estimate an ordered probit model, using these three possible outcomes, with the objective of gaining better ...

Lipid rafts in plasma membranes have emerged as possible platforms for the entry of HIV and other viruses into cells. However, little is known about how lipid phase heterogeneity contributes to viral entry because of the fine-grained and still poorly understood complexity of biological membranes. We used model systems mimicking HIV envelopes and T cell membranes and found that raft-like liquid-...

Objectives  To determine whether real-time passive notification of patient radiation exposure via a computerized physician order entry system would alter the number of computed tomography scans ordered by physicians in the Emergency Department (ED) setting. Methods  When a practitioner ordered a computed tomography scan, a passive notification was immediately and prominently displayed via the c...

Abstract We study equilibria in static entry games with single‐dimensional private information. Our framework embeds many models commonly used applied work, allowing for firm heterogeneity and selective entry. introduce the notion of strength, which summarizes a firm's ability to endure competition. In environments interest, an equilibrium strategies are ordered according firms' strengths alway...

INTRODUCTION Computerized decision support decreases the number of computed tomography pulmonary angiograms (CTPA) for pulmonary embolism (PE) ordered in emergency departments, but it is not always well accepted by emergency physicians. We studied a department-endorsed, evidence-based clinical protocol that included the PE rule-out criteria (PERC) rule, multi-modal education using principles of...

In this note, we consider ordered partitions of integers such that each entry is no more than a fixed portion of the sum. We give a method for constructing all such compositions as well as both an explicit formula and a generating function describing the number of k-tuples whose entries are bounded in this way and sum to a fixed value g.
