Consider the single server queue with an infinite buffer and a FIFO discipline, either of type M/M/1 or Geom/Geom/1. Denote by A the arrival process and by s the services. Assume the stability condition to be satisfied. Denote by D the departure process in equilibrium and by r the time spent by the customers at the very back of the queue. We prove that (D, r) has the same law as (A, s) which is...

Software-managed local stores have proven to be more efficient than hardware-managed caches for some important applications, yet their use has been mostly confined to embedded systems that run a small set of applications in a limited runtime environment. Local stores are problematic in general-purpose systems because they add to process state on context switches, and because they require fast d...

Remarkable progress was recently achieved in the studies on molecular regulators of iron metabolism. Among the main regulators, storage iron, iron absorption, erythropoiesis and hepcidin interact in keeping iron homeostasis. Diseases with gene-mutations resulting in iron overload, iron deficiency, and local iron deposition have been introduced in relation to the regulators of storage iron metab...

Considerable effort has been expended over the last decade on the production of persistent stores, for example CMS POMS, CPOMS, MONADS and Thatte's Persistent Memory. These generally did not provide for concurrent access to the store, and included no support for distribution. In this paper we investigate the distribution of persistent stores, including the issues of uniformity, unbounded size, ...

CT showed that our needle was too deep and the glue had reached the hypothalamus. The patient spent a week in the intensive care unit, and though he completely recovered, it still gives me goose bumps to think about it. There is no consensus about the most comfortable temperature. The way we perceive temperature has a lot to do with the humidity accompanying it. For example, if the humidity is ...

In response to lack of access to healthy foods, many low-income communities are instituting local healthy corner store programs. Some stores also participate in the United States Department of Agriculture's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and the Supplemental Nutrition Assistance Program (SNAP). This study used two assessment tools to compare the he...

OBJECTIVE To assess and evaluate the drug storage quality and regulatory compliance among privately operated drug stores of Karachi Pakistan. METHODS A cross-sectional survey of drug stores located in Karachi was conducted from May to December 2013. A total of 1003 drug stores that were involved in the sales, purchase and dispensing of pharmaceutical products were approached by non-probabilit...

BACKGROUND Aspects of the food environment such as the availability of different types of food stores have recently emerged as key modifiable factors that may contribute to the increased prevalence of obesity. Given that many of these studies have derived their results based on secondary datasets and the relationship of food stores with individual weight outcomes has been reported to vary by st...

INTRODUCTION Small food stores are prevalent in urban neighborhoods, but the availability of nutritious food at such stores is not well known. The objective of this study was to determine whether data from 3 sources would yield a single, homogenous, healthful food store category that can be used to accurately characterize community nutrition environments for public health research. METHODS We...
