Giant Molecular Clouds are More Concentrated to Spiral Arms than Smaller Clouds

From our catalog of Milky Way molecular clouds, created using a temperature thresholding algorithm on the Bell Laboratories CO Survey, we have extracted two subsets: (1) Giant Molecular Clouds (GMCs), clouds that are definitely larger than 10 M⊙, even if they are at their “near distance”, and (2) clouds that are definitely smaller than 10 M⊙, even if they are at their “far distance”. The positi...

The Arms Race in P2P

Peer-to-peer (P2P) networks have recently grown in popularity for a variety of applications such as content distribution, streaming multimedia and voice-over IP. P2P networks are built around a decentralized architecture to distribute data in a manner that offers high availability of content, inherent fault-tolerance and efficiency. While P2P networks offer several important advantages over tra...
