Galax is a lightweight , portable, open-source implementation of XQuery 1.0. Started in Decem-ber 2000 as a small prototype designed to test the XQuery static type system, Galax has now become a solid implementation, aiming at full conformance with the family of XQuery 1.0 specifications. Because of its completeness and open architecture , Galax also turns(More)
BACKGROUND Progressive multifocal leukoencephalopathy (PML) in natalizumab-treated MS patients is linked to JC virus (JCV) infection. JCV sequence variation and rearrangements influence viral pathogenicity and tropism. To better understand PML development, we analyzed viral DNA sequences in blood, CSF and/or urine of natalizumab-treated PML patients. (More)
One of the fundamental challenges in the management of converged networks is how to efficiently represent user profile information. In this technical report we outline the underlying technical challenges as well as our approach for modeling, storing and manipulating user profile information in a central profile server. The schema and algorithms described(More)
With recent advances in plant biotechnology, transgenic plants have been targeted as an inexpensive means for the mass production of proteins for biopharmaceutical and industrial uses. However, the current plant purification techniques lack a generally applicable, economic, large-scale strategy. In this study, we demonstrate the purification of a model(More)
Over half of adults are seropositive for JC polyomavirus (JCV), but rare individuals develop progressive multifocal leukoencephalopathy (PML), a demyelinating JCV infection of the central nervous system. Previously, PML was primarily seen in immunosuppressed patients with AIDS or certain cancers, but it has recently emerged as a drug safety issue through(More)
Rapid advancements in processor and networking technologies have led to the evolution of cluster and grid computing frameworks. These high-performance computing environments exploit geographically distributed, diverse resources, with the goal to provide efficient computing solutions to all kinds of parallel and distributed applications. The power of such(More)
