Small RNAs (sRNA) of 15-30 nucleotides regulate various processes in eukaryotes. Regulatory sRNAs are produced through the RNA interference (RNAi) pathway from double stranded RNA (dsRNA). Dicer or dicer-like enzyme processes the dsRNAs into 15-30 bp dsRNAs, which in turn bind to the RNA-induced silencing complex (RISC) to regulate gene expression. We previously cloned sRNAs from barley. In thi...

Let Z and IR (C) denote the ring of the integers and the field of real (complex) numbers, respectively. For a field F, we put i* = F\{0}. Fix A GC and B G C*, and let X(A, B) consist of all those second-order recurrent sequences {wn}neZ of complex numbers satisfying the recursion: n+i = „ ~ n-i (i.e., Bwn_Y = Awn wn+l) for n = 0, ± 1, ± 2,.... (1) For sequences in SE(A,B), the corresponding cha...

There is good agreement am:mg the people of various ti.rres and cultures concerning the basic elements present in the world. In nature there are celestial J:xxlies and rrovements, weather, plants and animals, and the land and water of the earth's surface. In htmliID affairs there are families, problems of food and reproduction, social and political structures, and experiences of unseen realitie...

In this paper, we present two contributions for Arabic Word Sense Disambiguation. In the first one, we propose to use both two external resources AWN and WN based on Term to Term Machine Translation System (MTS). The second contribution relates to the disambiguation strategies, it consists of choosing the nearest concept for the ambiguous terms, based on more relationships with different concep...
