We evaluated theanti-arthritic and antinociceptive properties of an ethanolic extract of E. polystachya (EE) barkand its rich-flavonoids frac...

Rich-club and page-club coefficients and their null models are introduced for directed graphs. Null models allow for a quantitative discussion of the rich-club and page-club phenomena. These coefficients are computed for four directed real-world networks: Arxiv High Energy Physics paper citation network, Web network (released from Google), Citation network among US Patents, and Email network fr...
