High Performance Computing (HPC) applications are scientific applications that require significant CPU capabilities. They are also data-intensive applications requiring large data storage. While many researchers have examined the performance of Amazon’s EC2 platform across some HPC benchmarks, an extensive study and their comparison between Amazon’s EC2 and Microsoft’s Windows Azure is largely ...

leukocyte physiology related to the genesis or perpetuation of the leukemic state. Ilistochemical,2,’ biochemical4 and fine structural studies5’t’ have defined a number of similarities between Auer rods and the primary dense particles of immature granulocytes, the azurophilic granules. The resemblance of the two types of cytoplasmic organelles has prompted the conclusion that Auer bodies are un...

Finding key vertices in large graphs is an important problem in many applications such as social networks, bioinformatics, and distribution networks. Betweenness centrality is a popular algorithm for finding such vertices and has been studied extensively, yielding several parallel formulations suitable to supercomputers and clusters. In this paper we implement and study betweenness centrality i...

Many modern scalable cloud networking architectures rely on host networking for implementing VM network policy e.g. tunneling for virtual networks, NAT for load balancing, stateful ACLs, QoS, and more. We present the Virtual Filtering Platform (VFP) a programmable virtual switch that powers Microsoft Azure, a large public cloud, and provides this policy. We define several major goals for a prog...

HE INTRODUCTION OF the carboxylic acid cation exchange Amberlite XE-96 (or IRC-50) Azure A resin’ as the medium for hydrogen ion exchange in place of the quininium exchange resin has simplified greatly the determination of gastric acidity without intubation (1). Solvent extraction and fluorimetry are no longer required. The amount of blue dye excreted in the urine is readily measured by visual ...

Chitinolytic activities were identified in the Protozoa Trichomonas vaginalis. Overall chitinase activity assessed using chitine-azure as substrate was 10.93 ± 1.21 nmoles/min/mg prot. End nonreducing chitobiosidase (exochitinase) and chitotriosidase (endochitinase) activities were shown using p-nitrophenyl-substrates and had specific activities of 4 .55 ± 0.53 and 0.47 ± 0.06 nmol/min/mg prot,...

Cloud Contracts capture architectural requirements in datacenters. They can be expressed as logical constraints over configurations. Contract violation is indicative of miss-configuration that may only be noticed when networks are attacked or correctly configured devices go off-line. In the context of Microsoft Azure’s data-center we develop contracts for (1) network access restrictions, (2) fo...

Methods Determining how academic clinical trials units can optimise data quality via central monitoring methods is an important factor in trial management. In the AZURE trial, it became apparent from site monitoring that the endpoint dates as defined in EORTC literature [1] were misinterpreted at site. Although a training programme was initiated, some sites were seen to report date of confirmat...

Resumen. Hoy en día, las tecnologías para la Internet aumentan a pasos agigantados, provocando la existencia de un gran número de proveedores de servicios en la nube como: Google App Engine, Windows Azure, Amazon E2C, entre otros. Esto a su vez hace que las empresas adoptantes sean más exigentes al adquirir un servicio. En este sentido, este trabajo propone un análisis comparativo entre los dif...
