Based on intravascular ultrasound (IVUS) video images, a novel motion estimation method combining the genetic algorithm-based optical flow method and a step-by-step and sum strategy has been developed to estimate the displacement and strain distributions on the scan cross sections of the arteries. And then, real elasticity distributions were reconstructed(More)
BACKGROUND Dry eye syndrome (DES) is a common ocular disorder occurring in general population. The purpose of this study is to evaluate the impact of DES on vision-related quality of life (QoL) in a non-clinic-based general population. METHODS This population-based cross-sectional study enrolled subjects older than 40 years, who took part in an(More)
In this paper, we study the problem of summarizing email conversations. We first build a sentence quotation graph that captures the conversation structure among emails. We adopt three cohesion measures: clue words, semantic similarity and cosine similarity as the weight of the edges. Second, we use two graph-based summarization approaches, Generalized(More)
To investigate the effects of visible light on the retinal development, we established an early-light-exposure model in neonatal mice. An incision was made on the right-sided eyelids of mice on postnatal day 4 (P4), and so that the right eyes were exposed to visible light (4000 lux) for 12h per day. The population in the retinal ganglion cells (RGCs),(More)
The popularity of email has triggered researchers to look for ways to help users better organize the enormous amount of information stored in their email folders. One challenge that has not been studied extensively in text mining is the identification and reconstruction of hidden emails. A hidden email is an original email that has been quoted in at least(More)
The popularity of email has triggered researchers to look for ways to help users better organize the enormous amount of information stored in their email folders. One challenge that has not been studied extensively in text mining is the reconstruction of hidden emails. A hidden email is an original email that has been quoted in subsequent emails but is not(More)
