Geographic opportunistic routing (GOR) is a new routing concept in multihop wireless networks. In stead of picking one node to forward a packet to, GOR forwards a packet to a set of candidate nodes and one node is selected dynamically as the actual forwarder based on the instantaneous wireless channel condition and node position and availability at the time(More)
Hadoop is widely adopted to support data intensive distributed applications. Many of them are mission critical and require inherent high availability of Hadoop. Unfortunately, Hadoop has no high availability support yet, and it is not trivial to enhance Hadoop. Based on thorough investigation of Hadoop, this paper proposes a metadata replication based(More)
The functional specificity of type 1 protein phosphatases (PP1) depends on the associated regulatory/targeting and inhibitory subunits. To gain insights into the mechanism of PP1 regulation by inhibitor-2, an ancient and intrinsically disordered regulator, we solved the crystal structure of the complex to 2.5A resolution. Our studies show that, when(More)
In this paper, we study the geographic collaborative forwarding (GCF) scheme, a variant of opportunistic routing, which exploits the broadcast nature and spatial diversity of the wireless medium to improve the packet delivery efficiency. Our goal is to fully understand the principles, the gains, and the tradeoffs of the node collaboration and its associated(More)
Cloud platforms offer resource utilization as on demand service, which lays the foundation for applications to scale during runtime. However, just-in-time scalability is not achieved by simply deploying applications to cloud platforms. Existing approaches require developers to rewrite their applications to leverage the on-demand resource utilization, thus(More)
Real-time parking availability information is important in urban areas, and if available could reduce congestion, pollution, and gas consumption. In this paper, we present a software solution called PhonePark for detecting the availability of on-street parking spaces. The solution uses the GPS and/or accelerometer sensors in a traveler's mobile phone to(More)
Raf kinase inhibitor protein (RKIP) has been shown to be a metastasis suppressor in many kinds of malignant tumors. But its function in breast cancer was not yet clarified completely. We detected RKIP expression in clinical samples of primary breast cancer, breast cancer metastases, and in different breast cancer cells. Compared with the normal breast(More)
The medicinal properties of curcumin are well documented in Indian and Chinese systems of medicine, which refer to its wide use in the treatment of some diseases. It has shown to have anti-carcinogenic properties and is known to prevent tumor development in some cancers. In our study, we confirmed that the expression of miR-15a and miR-16 was upregulated(More)
OBJECTIVE The objective of this study was to compare 2-dimensional intraoral digital images with 3-dimensional cone beam CT (CBCT) in assessment of periodontal bone levels and defects. METHODS Thirty periodontal bone defects of 2 adult human skulls (with soft tissue or substitute) were evaluated by using intraoral digital radiography and CBCT. Digital(More)
The human p100 protein is a vital transcription regulator that increases gene transcription by forming a physical bridge between promoter-specific activators and the basal transcription machinery. Here we demonstrate that the tudor and SN (TSN) domain of p100 interacts with U small nuclear ribonucleoprotein (snRNP) complexes, suggesting a role for p100 in(More)
