We describe a novel adaptive wavelet-based compression scheme for images which takes advantage of image redundancy across scales. As with standard wavelet transform coders, our compressed image representation consists of a set of quantized wavelet coeecients and quantized wavelet subtrees. Instead of having a xed sub-tree codebook, however, we construct a(More)
The lack of standardized terminology in pelvic floor disorders (pelvic organ prolapse, urinary incontinence, and fecal incontinence) is a major obstacle to performing and interpreting research. The National Institutes of Health convened the Terminology Workshop for Researchers in Female Pelvic Floor Disorders to: (1) agree on standard terms for defining(More)
A DNA fusion containing the promoter of the pir gene of plasmid R6K that encodes for the pi-initiation protein and the beta-galactosidase gene of Escherichia coli (lacZ) is described. The synthesis of beta-galactosidase promoted by this pir-lac fusion was almost completely inhibited when an R6K sequence containing the pir gene was provided in trans in E.(More)
