The homeobox gene family of Drosophila appears to control a variety of position-specific patterning decisions during embryonic and imaginal development. Most of these patterning decisions determine groups of cells on the anterior-posterior axis of the Drosophila germ band. We have isolated a novel homeobox gene from Drosophila, designated H2.0. H2.0 has the(More)
H2.0, a homeobox gene identified by homology to the Sex combs reduced homeobox of Drosophila, is expressed in all the cellular precursors of the visceral musculature. By analogy to the essential function of most other known homeobox genes in determining the fate of cells where they are expressed, we hypothesized that mutation of H2.0 would disrupt gut(More)
This paper presents Timed Petri Nets (TPN) as an analytical approach for verification of computerized queueing network simulation models at steady state. It introduces a generic approach to decomposing a queueing network into separate and independent TPNs, each representing a resource of specific type, such as a processing resource or a transporting(More)
A hybrid grid approach has been developed for the simulation of next generation heavy-lift space vehicles in the launch environment. The motivation for the hybrid method is to reduce the turnaround time of computational fluid dynamic simulations and improve the ability to handle complex geometry and flow physics. The LAVA (Launch Ascent and Vehicle(More)
Emergency department crowding is a significant international problem. The problem is on the edge of the emergency department and the departments where the patients will be subsequently admitted, provided they are not discharged. In this paper we present an analysis of the factors affecting waiting time in the emergency department of an eminent hospital in(More)
