In this paper, we investigate the multicast routing problem in sparse splitting networks (MR-SSN). The MRSSN problem is to find a route from the source node of a session to all destinations of the session such that the total number fibers used in establishing the session is minimized while the multicast capable nodes are evenly distributed throughout the(More)
In this paper, we investigate the problem of Multicast Routing in Sparse Splitting Networks (MR-SSN). Given a network topology with the multicast capable nodes distributed uniformly throughout the network, and a multicast session, the MR-SSN problem is to find a route from the source node of the multicast session to all destinations of the multicast session(More)
Ag2Se quantum dots (QDs) have attracted a lot of interest due to their potential applications in biosensing and bioimaging. A strategy is presented that involves coupling of selenium powder reduction with the binding of silver ions, and thioglycollic acid (TGA) and glycine as stabilizers to obtain ultrasmall Ag2Se QDs at 85 °C in aqueous solution. This(More)
OBJECTIVE To observe the effect of vasoactive intestinal peptide (VIP) on the metabolism of intestinal fluid and cyclic AMP protein kinase A signaling pathway (cAMP-PKA) and water channel protein 3 (AQP3) in rats with constipation, and to explore the mechanism of VIP in the treatment of constipation.
 Methods: A total of 45 healthy adult rats were randomly(More)
Global warming and its accompanying sea level rise will be serious issues in the future. According to the Intergovernmental Panel on Climate Change (IPCC) , a global average sea level rise of 9cm to 88cm is projected for 1990 to 2100 and a steady increase of sea level for all of the scenarios considered is expected. In the coast regions, coast disasters(More)
