YouTube uploaders are the central agents in the YouTube phenomenon. We conduct extensive measurement and analysis of YouTube uploaders. We estimate YouTube scale and examine the uploading behavior of YouTube users. We demonstrate the positive reinforcement between on-line social behavior and uploading behavior. Furthermore, we examine whether YouTube users(More)
In Delay Tolerant Networks (DTNs), information search is an important topic, which has not been widely investigated yet. Recently, pervasive and ubiquitous computing scenarios are pushing situations where it is the recipient (instead of the sender) who determines whether and how to seize data flowing in the network. Most existing information search schemes(More)
A current-mode mm-wave direct-conversion receiver breaking trade-offs among bandwidth, NF and linearity is designed and realized in 65nm CMOS. The 60GHz receiver employs novel Frequency-staggered Series Resonance Common Source (FSRCS) stage to extend RF bandwidth with superior noise performance. The receiver's current-mode operation offers excellent(More)
In mobile social networks (MSNets), data dissemination is an important topic, which has not been widely investigated yet. Active data dissemination is a networking paradigm where a superuser intentionally facilitates the connectivity in the network. One of the key challenges under this paradigm is how to design the most efficient superuser route to achieve(More)
A current-mode 60-GHz direct-conversion receiver, which can break performance tradeoffs among bandwidth, noise figure (NF), and linearity is designed and realized in 65-nm CMOS. The 60-GHz receiver employs the novel frequency-staggered series resonance common source (FSRCS) stage to extend RF bandwidth with superior noise performance. The receiver's(More)
As constituents of lysosomes, lysosomal membrane proteins play important roles in lysosome-related autophagy and apoptosis. In a recent proteomic study of lysosomal proteins, we identified transmembrane protein 192 (TMEM192) as a novel lysosomal membrane protein candidate. Using specific anti-TMEM192 antibody (More)
In this paper, we consider the issue of data broadcasting in mobile social networks (MSNets). The objective is to broadcast data from a superuser to other users in the network. There are two main challenges under this paradigm, namely 1) how to represent and characterize user mobility in realistic MSNets; 2) given the knowledge of regular users' movements,(More)
