— Call graphs depict the static, caller-callee relation between " functions " in a program. With most source/target languages supporting functions as the primitive unit of composition , call graphs naturally form the fundamental control flow representation available to understand/develop software. They are also the substrate on which various interprocedural(More)
Wireless LAN (WLAN) market consists of IEEE 802.11 MAC standard conformant devices (e.g., access points (APs), client adapters) from multiple vendors. Certain third party certifications such as those specified by the Wi-Fi alliance have been widely used by vendors to ensure basic conformance to the 802.11 standard, thus leading to the expectation that the(More)
This study concerns the self-assembly of virus-like particles (VLPs) composed of an icosahedral virus protein coat encapsulating a functionalized spherical nanoparticle core. The recent development of efficient methods for VLP self-assembly has opened the way to structural studies. Using electron microscopy with image reconstruction, the structures of(More)
This paper presents the design and implementation of a host-based driver (a " volume manager ") for a 3-tier RAID storage system, currently with 3 tiers: a small RAID1 tier and larger RAID5 and compressed RAID5 (cRAID5) tiers. Based on access patterns (" temperature "), the driver automatically migrates frequently ac-cessed data to RAID1 while demoting not(More)
Brome mosaic virus (BMV) RNA replication has been examined in a number of systems, including Saccharomyces cerevisiae. We developed an efficient T-DNA-based gene delivery system using Agrobacterium tumefaciens to transiently express BMV RNAs in Nicotiana benthamiana. The expressed RNAs can systemically infect plants and provide material to extract BMV(More)
A virus isolate causing mosaic disease of commercial sugarcane was purified to homogeneity. Electron microscopy revealed flexuous filamentous virus particles of ca 890 x 15 nm. The virus isolate reacted positively with heterologous antiserum to narcissus latent virus form UK, but failed to react with potyvirus group specific antiserum. N-terminal sequencing(More)
The ever-increasing volume of archival data that needs to be reliably retained for long periods of time and the decreasing costs of disk storage, memory, and processing have motivated the design of low-cost, high-efficiency disk-based storage systems. However, <i>managed</i> disk storage is still expensive. To further lower the cost, redundancy can be(More)
