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 the FDDI guarantees a bounded access delay and an average bandwidth for synchronous traac. However, this fact alone cannot eeectively support many real-time applications that require the timely delivery of each critical message. We solve this problem by developing a synchronous bandwidth allocation SBA scheme which calculates the(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)
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)
A new antitumor and antioxidant peptide (H3) was isolated from Arca subcrenata Lischke using ion exchange and hydrophobic column chromatography. The purity of H3 was over 99.3% in reversed phase-high performance liquid chromatography (RP-HPLC) and the molecular weight was determined to be 20,491.0 Da by electrospray-ionization mass spectrometry (ESI-MS/MS).(More)
