The efficient and robust extraction of repetitive patterns from images is a ground challenge problem in computer vision. The repetitive patterns in images are products of both repetitive structures as well as repetitive reflections or color patterns. The perception of repetitive patterns in an image is strongly linked to the visual interpretation and composition of objects or textures. In other...

DNA Sequence, Satellite DNA, Cucumis melo The primary sequence of the prominent Cucumis melo satellite DNA is presented. The cloned Hind Ill-repeat unit has a length of 352 bp and a GC-content of 56%. Within this sequence an inverted repeat of 9 bp, including a 286 bp loop, and one direct repeat are shown. Several open reading frames are possible following the sequence in both directions whose ...

We have previously shown that computer simulations of processes that generate selectively advantageous changes together with random duplications and deletions give rise to genomes with many different genes embedded in a large amount of dispensable DNA sequence. We now explore the consequences of neutral changes on the evolution of genomes. We follow the consequences of sequence divergences that...

OBJECTIVES This article describes the characteristics of people who report a repetitive strain injury (RSI) and examines the association of an RSI with chronic pain and with psychological distress. DATA SOURCES The data are from Statistics Canada's 2000/01 Canadian Community Health Survey (CCHS) and the 1994/95 to 2000/01 National Population Health Survey (NPHS). ANALYTICAL TECHNIQUES Cross...
