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)
In mice and in young adult humans, the subventricular zone (SVZ) contains multipotent, dividing astrocytes, some of which, when cultured, produce neurospheres that differentiate into neurons and glia. It is unknown whether the SVZ of very old humans has this capacity. Here, we report that neural stem/progenitor cells can also be cultured from rapid autopsy(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)
We propose a quantum key distribution scheme that combines a biased basis choice with the decoy-state method. In this scheme, Alice sends all signal states in the Z basis and decoy states in the X and Z basis with certain probabilities, and Bob measures received pulses with optimal basis choice. This scheme simplifies the system and reduces the random(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)
Grid computing is the key technology of next generation Internet. A promising way of solving the problem of resource allocation in a grid environment is a procedure based upon resource pricing. In Grid Computing Environment , it is very important how to allocate resources for achieving the goal of high effective utilization of resources. This paper targets(More)
