Familial hypertrophic cardiomyopathy (HCM) is a prevalent hereditary cardiac disorder linked to arrhythmia and sudden cardiac death. While the causes of HCM have been identified as genetic mutations in the cardiac sarcomere, the pathways by which sarcomeric mutations engender myocyte hypertrophy and electrophysiological abnormalities are not understood. To(More)

Packrat parsing is a powerful parsing algorithm presented by Ford in 2002. Packrat parsers can handle complicated grammars and recursive structures in lexical elements more easily than the traditional <i>LL(k)</i> or <i>LR</i>(1) parsing algorithms. However, packrat parsers require <i>O(n)</i> space for memoization, where <i>n</i> is the length of the(More)
In this paper, we present a thread-based programming model for the EM-4 hybrid dataflow machine, where parallelism and synchronization among threads of sequential execution are described explicitly by the programmer. Although EM-4 was originally designed as a dataflow machine, we demonstrate that it provides effective architectural support for a variety of(More)
Accumulating evidence indicates that TNFalpha plays an important role in the pathogenesis of periodontitis, but the effect of TNFalpha on the degradation of the periodontal ligament is not well understood. This study used reverse transcriptase-PCR to investigate the effects of TNFalpha on matrix metalloproteinase (MMP) mRNA expression in human periodontal(More)
This paper proposes a method of generating a lightweight scalable NFA-based string matching circuit with elimination of redundant resources. String matching circuits have been studied extensively for intrusion detection systems. An NFA-based string matching circuit, one of the works, has expandability of the processing data width. Due to the huge hardware(More)
Latency tolerance is essential in achieving high performance on parallel computers for remote function calls and fine-grained remote memory accesses. EM-X supports interprocessor communication on an execution pipeline with small and simple packets. It can create a packet in one cycle, and receive a packet from the network in the on-chip buffer without(More)
The design and performance of a priority f omarding router chip are presented. The chip has four input and four output ports, employs clock-synch,ronited packet switching, and facilitates 32-bit priority arbitration by means of a priority forwarding scheme that prevents priohty inversion and enables accurate pr i ority control within a network. Packets are(More)
