This paper presents a system to facilitate the mobile devices to browse and retrieve video clips from a large amount of media contents. The media server in the proposed system is capable of recommending video clips to users that is adapt to their resolutions. Users are able to send feedbacks about user experiences to the server through the interactive client. Based on the user feedbacks, the media server could update the metadata for video clips such as popularity and acceptable resolution. In addition, redundant versions with lower resolution are generated for video clips by estimating their popularities, and sent to users with lower resolution directly to save the downsizing transcoding process. Experimental results demonstrate that user experiences are improved according to the increase of positive user feedbacks and the decrease of average transcoding delay.
We propose that locations of genes on chromosomes can contribute to the prediction of gene regulatory relationships. We constructed a time-based gene regulatory network of zebrafish cardiogenesis on the basis of a spatio-temporal neighborhood method. Through the network, specific regulatory pathways and order of gene expression during zebrafish cardiogenesis were obtained. By comparing the order with locations of these genes on chromosomes, we discovered that there exists a reversal phenomenon between the order and order of gene locations. The discovery provides an inherent rule to instruct exploration of gene regulatory relationships. Specifically, the discovery can help to predict if regulatory relationships between genes exist and contribute to evaluating the correctness of discovered gene regulatory relationships.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
