Thin‐Film Transistor Based Active Taxel for Multimode Tactile Perception and Fused Processing
Advanced Science, EarlyView.Skin serves as the largest‐area organ for human and embodied intelligent robots, providing tactile interaction. An active multimode fused (AMF) artificial skin is developed using standard TFT processes, featuring 2T‐1C taxels with optical and electrostatic capacitive receptors for cross‐modal sensing.

Network locality in wireless networks
2013 ACS International Conference on Computer Systems and Applications (AICCSA), 2013The locality of reference is a well studied phenomenon in computer systems. As one special case, the network locality has been demonstrated to exist in the wired local area networks. Previous research suggests that the network traffic does not follow uniform distribution. In this paper, we explore the network locality in the wireless networks.

The Insecurity of Wireless Networks
IEEE Security & Privacy Magazine, 2012Wi-Fi is the standard protocol for wireless networks used extensively in US critical infrastructures. Since the Wired Equivalency Privacy (WEP) security protocol was broken, the Wi-Fi Protected Access (WPA) protocol has been considered the secure alternative compatible with hardware developed for WEP. However, in November 2008, researchers developed an

Authentication in Wireless Networks
2007 40th Annual Hawaii International Conference on System Sciences (HICSS'07), 2007With the explosive growth in the adoption of wireless networks in the recent years, the limitations of wireless security have become a topic of wide spread concern. It is easy for hackers to enter or leave a wireless network. They can directly attack the network and inject spurious packets, tamper with packets, drop packets, or impersonate another node.

Journal of Telemedicine and Telecare, 2008
Wireless telemedicine using GSM and GPRS technologies can only provide low bandwidth connections, which makes it difficult to transmit images and video. Satellite or 3G wireless transmission provides greater bandwidth, but the running costs are high. Wireless networks (WLANs) appear promising, since they can supply high bandwidth at low cost. However,

IEEE Network, 1997
Two network architectures for connecting fixed wireless nodes to a central concentrator-relay and star-are combined into a structured network architecture called a relay star network. A relay star network is characterized by the property that there is a unique communication path between any two nodes; that is, the graph of the network is a rooted tree.
