Collaborative spectrum sensing has been regarded as a promising approach to enable secondary users to detect primary users by exploiting spatial diversity. In this paper, we consider a converse question: could space diversity be exploited by a malicious entity, e.g., an external attacker or an untrusted Fusion Center (FC), to achieve involuntary geolocation(More)
UNLABELLED MicroRNAs (miRNAs) have recently been proposed as a versatile class of molecules involved in regulation of various biological processes. Although there is emerging evidence that some microRNAs can function as oncogenes or tumor suppressors, the specific role of miRNA in human hepatocellular carcinoma (HCC) is unclear at this point. In this study,(More)
Late-phase long-term potentiation (L-LTP) and long-term memory depend on the transcription of mRNA of CRE-driven genes and synthesis of proteins. However, how synaptic signals propagate to the nucleus is unclear. Here we report that the CREB coactivator TORC1 (transducer of regulated CREB activity 1) undergoes neuronal activity-induced translocation from(More)
In this paper, we introduce <i>Facet</i>, an unobservable transport service for social video sites. Facet evades detection by Internet censors by streaming social videos over Skype calls, and applying a novel traffic-analysis countermeasure called video morphing. We report on the performance and security of a prototype implementation of Facet and find that(More)
BACKGROUND AND AIMS Recently, some miRNAs have been reported to be connected closely with the development of human hepatocellular carcinoma. However, the functions of these miRNAs in HCC remain largely undefined. METHODS The expression profiles of miR-193b were compared between HCC tissues and adjacent normal liver tissues using qRT-PCR method. This(More)
Collaborative spectrum sensing is regarded as a promising approach to significantly improve the performance of spectrum sensing in Cognitive Radio Networks (CRNs). However, due to the open nature of wireless communications and the increasingly available software-defined radio platforms, collaborative spectrum sensing also poses many new research challenges,(More)
We introduce a novel algorithmic approach to content recommendation based on adaptive clustering of exploration-exploitation (“bandit”) strategies. We provide a sharp regret analysis of this algorithm in a standard stochastic noise setting, demonstrate its scalability properties, and prove its effectiveness on a number of artificial and real-world datasets.(More)
A novel actinomycete, designated as strain YIM 75980T, was isolated from a soil sample collected from a dry-hot river valley in Dongchuan county, Yunnan province, south-west China and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, red to black coloured colonies comprising coccoid-shaped cells. Colonies on(More)
CREB-target gene transcription during neuronal excitation is important for many aspects of neuronal development and function, including dendrite morphogenesis. However, the signaling events that regulate cAMP response element-binding protein (CREB)-mediated gene transcription during dendritic development are not well understood. Herein we report that the(More)
UNLABELLED Although gankyrin is involved in the tumorigenicity and metastasis of some malignancies, the role of gankyrin in cholangiocarcinoma (CCA) is unclear. In this study we investigated the expression of gankyrin in human CCA tissues and cell lines. The effects of gankyrin on CCA tumor growth and metastasis were determined both in vivo and in vitro.(More)
