Efficient routing among a set of mobile hosts (also called nodes) is one of the most important functions in ad hoc wireless networks. Routing based on a connected dominating set is a promising approach, where the searching space for a route is reduced to nodes in the set. A set is dominating if all the nodes in the system are either in the set or neighbors(More)
Visual experience scales down excitatory synapses in the superficial layers of visual cortex in a process that provides an in vivo paradigm of homeostatic synaptic scaling. Experience-induced increases in neural activity rapidly upregulates mRNAs of immediate early genes involved in synaptic plasticity, one of which is Arc (activity-regulated cytoskeleton(More)
Systemic exposure to nicotine induces glutamatergic synaptic plasticity on dopamine (DA) neurons in the ventral tegmental area (VTA), but mechanisms are largely unknown. Here, we report that single, systemic exposure in rats to nicotine (0.17 mg/kg free base) increases the ratio of DA neuronal currents mediated by AMPA relative to NMDA receptors (AMPA/NMDA(More)
Ternary content-addressable memories (TCAMs) have gained wide acceptance in the industry for storing and searching patterns in routers. But two important problems block the way to deploy TCAMs as deep package matching engines for network intrusion detection systems (NIDS): long patterns matching and range patterns matching. A novel high speed long patterns(More)
Recently, data mining over uncertain data streams has attracted a lot of attentions because of the widely existed imprecise data generated from a variety of streaming applications. In this paper, we try to resolve the problem of clustering over uncertain data streams. Facing uncertain tuples with different probability distributions, the clustering algorithm(More)

In the current Web 2.0 era, the popularity of Web resources fluctuates ephemerally, based on trends and social interest. As a result, content-based relevance signals are insufficient to meet users' constantly evolving information needs in searching for Web 2.0 items. Incorporating future popularity into ranking is one way to counter this. However,(More)
Recent advances in nanophotonic fabrication have made the optical network-on-chip an attractive interconnect option for next-generation multi-/many-core systems, providing high bandwidth and power efficiency. Both postfabrication and runtime calibration of the optical components (ring resonators) are essential to building a robust optical communication(More)
The aim of our study was to find a specific imaging (contrast-enhanced ultrasound, CEUS) to detect extracapsular extension and cervical lymph node metastases (ECE-LNM) that associated with BRAF protein expression in papillary thyroid carcinoma (PTC). Preoperative utrasonography (US) or CEUS was performed in the diagnosis of extracapsular extension (ECE) in(More)
