Piwi-interacting RNAs (piRNAs) silence transposons in animal germ cells. piRNAs are thought to derive from long transcripts spanning transposon-rich genomic loci and to direct an autoamplification loop in which an antisense piRNA, bound to Aubergine or Piwi protein, triggers production of a sense piRNA bound to the PIWI protein Argonaute3 (Ago3). In turn,(More)
Ranking of relevant objects plays an important role in various applications especially in multimedia database systems and information retrieval systems. In contrast to traditional database systems, multimedia database systems deal with similarity queries returning a list of objects ranked by the objects' overall score. The overall score for objects in the(More)
