Recently, we have proposed a computational method based on a random walk framework on a miRNA-target gene network to predict disease-associated miRNAs. The prediction performance of our method is better than that of some existing state-of …

Nettet1. jul. 2010 · It is well-known that for such random walks P { min 1 ≤ k ≤ n ∑ i = 1 k ξ i 0 ≥ 0 } ∼ c n as n → ∞ for a certain constant c > 0. On the other hand, η 0 ( N) ≍ N 1 / 2 in probability as N → ∞ because of another well-known fact that θ 1 0 belongs to the domain of normal attraction of an α -stable law with exponent 1/2. NettetPOSITIVITY OF INTEGRATED RANDOM WALKS VLADISLAV VYSOTSKY Abstract. Take a centered random walk Snand consider the sequence of its partial sums An:= Pn i=1Si. Suppose S1is in the domain of normal attraction of an α-stable law with 1 < α ≤ 2. Assuming that S1is either right-exponential (that is P(S1> x S1> 0) = e−ax
