inhibitors at developing frog embryos. Many of the chemicals that disrupted LR asymmetry (e.g., caused the normally leftlying heart to be situated on the right) displayed a common attribute: they influenced potassium transport into or out of the cell.

متن کاملChoose the Damping, Choose the Ranking?
To what extent can changes in PageRank’s damping factor affect node ranking? We prove that, at least on some graphs, the top k nodes assume all possible k! orderings as the damping factor varies, even if it varies within an arbitrarily small interval (e.g. [0.84999 , 0.85001]). Thus, the rank of a node for a given (finite set of discrete) damping factor(s) provides very little information about...
