In the past two decades, there has been a huge amount of document data with rich tag information during the evolution of the Internet, which can be called semi-structured data. These semi-structured data contain both unstructured features (e.g., plain text) and metadata, such as tags in html files or author and venue information in research articles. It's(More)
To date, there have been massive Semi-Structured Documents (SSDs) during the evolution of the Internet. These SSDs contain both unstructured features (e.g., plain text) and metadata (e.g., tags). Most previous works focused on modeling the unstructured text, and recently, some other methods have been proposed to model the unstructured text with specific(More)
Convolutional neural networks (CNN) based tracking approaches have shown favorable performance in recent benchmarks. Nonetheless, the chosen CNN features are always pre-trained in different task and individual components in tracking systems are learned separately, thus the achieved tracking performance may be suboptimal. Besides, most of these trackers are(More)
OBJECTIVE Construction of a small interfering RNA (siRNA) eukaryotic expression vector specific to mouse myocardin gene and study on the role of myocardin-siRNA on differentiation of mouse bone mesenchymal stem cells (MSCs) into smooth muscle-like cells induced by PDGF-BB in vitro. METHODS Mouse MSCs were isolated from bone marrow and cultured with 50(More)
Multi-aperture receiver with optical combining architecture is an effective approach to overcome the turbulent atmosphere effect on the performance of the free-space optical (FSO) communications, in which how to combine the multiple laser beams received by the sub-apertures efficiently is one of the key technologies. In this paper, we focus on the combining(More)
OBJECTIVE To investigate the expression profiles of myocardin gene during the differentiation of bone marrow-derived mesenchymal stem cell to smooth muscle cells in the conditional medium combined with a high concentration of fetal bovine serum (FBS). METHODS Marrow-derived mesenchymal stem cells were isolated and purified from mouse femoral bone and(More)
