An automated system for polymerase chain reaction (PCR) amplification and detection combats false-positive results caused by "PCR product carryover." The system uses a single vessel for both PCR amplification and the subsequent detection of PCR products, eliminating the need to handle PCR products in an open environment and risk product carryover. The sample and PCR reagents are introduced into...
The automatic analysis of retinal blood vessels plays an important role in the computer-aided diagnosis. In this paper, we introduce a probabilistic tracking-based method for automatic vessel segmentation in retinal images. We take into account vessel edge detection on the whole retinal image and handle different vessel structures. During the tracking process, a Bayesian method with maximum a p...
background: autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. the biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
