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 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 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 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)
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)
Mobility pattern of device users plays a crucial role in a wide range of mobile computing applications, including data forwarding, content sharing, information search and advertising. Hence, it is important to characterize the mobility path information of users, so as to accurately predict user mobility. In this paper, we introduce two typical user mobility(More)
This paper presents a novel self-equalized and skewless frequency-division multiplexing memory interface. To prove its feasibility, we have realized a 5-band QPSK transceiver in 40 nm CMOS to transmit up to 4 Gb/s through 10 orthogonal communication channels (each with 400 Mb/s) via on-chip TSV emulator with effective loading of 1 pF or 5-cm FR-4 PCB trace.(More)
