The problem solved in this paper is to design a video streaming protocol which is accomplished by the application layer multicast in the WLANThis protocol, WVALM, divides the whole video streaming into small blocks, and achieves the requirement of streaming multicast by multicasting those small blocksThe receiver and the sender use streaming window and retransmit window respectively to coordinate their relationshipThrough experiment test, WVALM achieves the original object and could work well in the wireless environment.
Non-deterministic polynomial (NP)-complete problems are collections of intractable problems for classical computers, but they may be easier to solve for quantum computers. Considering that practical quantum computers ...

Benefiting from the development of molecular electronics and molecular plasmonics, the interplay of light and electronic transport in molecular junctions has attracted growing interest among researchers in both fields, leading to a new research direction of "single-molecule optoelectronics". Here, we review the latest developments of photo-modulated charge transport,electroluminescence and Raman spectroscopy from single-molecule junctions, and suggest future directions for single-molecule optoelectronics.
