Mobile ad hoc networks (MANET) is a new networking paradigm for wireless hosts. Because of infrastructureless, self-organization, dynamic topology and openness of wireless links, the routing security problem in MANET is more seriously than in wired networks. Optimized link state routing (OLSR) (T. Clausen et al., 2003) is proposed by IETF's MANET Group at(More)
In real-world graphs such as social networks, Semantic Web and biological networks, each vertex usually contains rich information, which can be modeled by a set of tokens or elements. In this paper, we study a subgraph matching with set similarity (SMS<sup>2</sup>) query over a large graph database, which retrieves subgraphs that are structurally isomorphic(More)

Modulation classification is to identify the modulation type of a received signal automatically. It is a promising technique that can increase the throughput of adaptive modulation systems such as IEEE 802.11 and HIPERLAN systems. While a variety of approaches have been proposed for modulation classification, most of them rely on the unrealistic assumption(More)
OBJECTIVE We developed an augmented reality system that enables intraoperative image guidance by using 3-dimensional (3D) graphics overlaid on a video stream. We call this system DEX-Ray and report on its development and the initial intraoperative experience in 12 cases. METHODS DEX-Ray consists of a tracked handheld probe that integrates a lipstick-size(More)
Amyloid-beta (Abeta) peptide is the original causative factor of Alzheimer's disease (AD) according to the amyloid cascade hypothesis. The ubiquitin-proteasome system (UPS), the major intracellular protein quality control system in eukaryotic cells, is related to AD pathogenesis. There is growing evidence showing that there is a tight relationship between(More)
