Unlike relative location information, obtaining absolute location in multi-hop way usually requires anchor nodes to periodically flood the network. However, due to the limited resource of sensor nodes, this causes significant reduction in sensor nodes lifetime. In this paper, we propose a localization system called Mosaic. As the name implies, by matching pieces of the puzzle, which plays similar...
Phosphoinositide 3-kinases (PI3Ks) have known to be key enzymes activating intracellular signaling molecules when a number of growth factors bind to their cell surface receptors. PI3Ks are divided into three classes (I, II, and III) and enzymes of each class have different tissue-specificities and physiological functions. Class II PI3Ks consist of three isoforms (α,β,γ). Although the α-isoform (PI3K-C2α)...
