DART is an ATM Network Interface Controller chip designed for both high bandwidth and low overhead communication. Innovative features are direct, protected application access to/from the network, host-assisted flow control, and¨message processing¨for flexible low overhead communication mechanisms. DART is being manufactured as a commercial product by(More)
It is well-known that an FDDI token ring network provides a guaranteed throughput for synchronous messages and a bounded medium access delay for each nodeestation. However, this fact alone cannot eeectively support many real-time applications that require the timely delivery of each critical message. The reason for this is that the FDDI guarantees a medium(More)
Iron is critical for virtually all forms of life. The production of high-affinity iron chelators, siderophores, and the subsequent uptake of iron-siderophore complexes are a common strategy employed by microorganisms to acquire iron. Staphylococcus aureus produces siderophores but genetic information underlying their synthesis and transport is limited.(More)
In order to realize real-time communication over Ether-net or fast Ethernet, one must be able to bound the medium access time within an acceptable limit. The multiple access nature of an Ethernet makes it impossible to guarantee a deterministic medium access time (hence packet delivery deadlines) to individual stations. However, one can bound the medium(More)

MapReduce has been used at Google, Yahoo, FaceBook etc., even for their production jobs. However, according to a recent study, a single failure on a Hadoop job could cause a 50% increase in completion time. Amazon Elastic MapReduce has been provided to help users perform data-intensive tasks for their applications. These applications may have high fault(More)
Primary sensory neurons in the DRG play an essential role in initiating pain by detecting painful stimuli in the periphery. Tissue injury can sensitize DRG neurons, causing heightened pain sensitivity, often leading to chronic pain. Despite the functional importance, how DRG neurons function at a population level is unclear due to the lack of suitable(More)
