Construction of Small Worlds in the Physical Topology of Wireless Networks

The concept of small worlds is introduced into the physical topology of wireless networks in this work. A. Helmy provided two con- struction schemes of small worlds for the wireless networks, link rewiring and link addition, but he mainly focused on the virtual topology. Based on the broadcasting nature of the radio transmission, we propose a con- struction scheme of small worlds for the physical topology of Multiple- Input Multiple-Output (MIMO) wireless networks. Besides the topology- related topics, we also evaluate the reduction of the power required by a request.

SUMO Substrates and Sites Prediction Combining Pattern Recognition and Phylogenetic Conservation

Small Ubiquitin-related modifier (SUMO) proteins are widely expressed in eukaryotic cells, which are reversibly coupled to their substrates by motif recognition, called sumoylation. Two interesting questions are 1) how many potential SUMO substrates may be included in mammalian proteomes, such as human and mouse, 2) and given a SUMO substrate, can we recognize its sumoylation sites? To answer these two questions, previous prediction systems of SUMO substrates mainly adopted the pattern recognition methods, which could get high sensitivity with relatively too many potential false positives. So we use phylogenetic conservation between mouse and human to reduce the number of potential false positives.
