Heavy hitters, which are items occurring with frequency above a given threshold, are an important aggregation and summary tool when processing data streams or data warehouses. Hierarchical heavy hitters (HHHs) have been introduced as a natural generalization for hierarchical and multi-dimensional data domains. An important application, for instance, involves inferring patterns in the stream of ...

2'-O-methylation of eukaryotic ribosomal RNA (r)RNA, essential for ribosome function, is catalysed by box C/D small nucleolar (sno)RNPs. The RNA components of these complexes (snoRNAs) contain one or two guide sequences, which, through base-pairing, select the rRNA modification site. Adjacent to the guide sequences are protein-binding sites (the C/D or C'/D' motifs). Analysis of >2000 yeast box...
