The focus of this work was to explore the mediation of abscisic acid(ABA) on woundinduced suberization and to determine expression profiles of specific genes involved in wound-induced suberization in tomato fruit. The measurements of weight loss and fruit firmness suggested wound-induced suberization started at 2 d after wounding. The suberization process with the accumulation of suberin polyphenolics(SPP) and polyaliphatics(SPA) observed through autofluorescence microscopy and Sudan IV staining was accelerated by ABA. Expressions of SlPAL5 and Sl4 CL involved in the synthesis of SPP reached the highest at 4 and 8 d after wounding following ABA application, respectively. Associated with SPA biosynthesis, SlLACS1 and SlLACS2 showed the most abundant transcripts at 8 and 6 d in ABA group, respectively. Transcript levels including SlKCSs, SlCYP86 B1, SlFAR3, and Sl GPATs were up-regulated at 2 d after wounding by ABA. Activities of polyphenol oxidase and lipoxygenase were also enhanced during wound-induced suberization following ABA application. The results in this study proved that ABA accelerated the wound-induced suberization progress by increasing the transcript levels of relevant genes in postharvest tomato fruit.展开更多

This paper described the advantages and principles of the Hibernate, and then showed the written work of the configuration files, mapping files, persistent classes, etc. Finally, the paper showed how to display the specific data information in the TableViewer based on the Eclipse RCP framework. It is observed that, operating the objects in the Hibernate framework is more flexible and efficient than using JDBC directly. Ad in addition, the application based on Eclipse RCP framework can take over many excellent features of Eclipse, and the developers can improve their efficiency by these features.展开更多

In the last few years, plenty of methods have been proposed for key-frame extraction of motion capture data, and it is a common method to extract key-frame using quaternion. Here, one main difficulty is due to the fact that previous algorithms often need to manually set various parameters. In addition, it is problematic to predefine the appropriate threshold without knowing the data content. In this paper, we present a novel adaptive threshold-based extraction method. Key-frame can be found according to quaternion distance. We propose a simple and efficient algorithm to extract key-frame from a motion sequence based on adaptive threshold. It is convenient with no need to predefine parameters to meet certain compression ratio. Experimental results of many motion captures with different traits demonstrate good performance of the proposed algorithm. Our experiments show that one can typically cut down the process of extraction from several minutes to a couple of seconds.展开更多

The research of on-orbit service spacecraft orbit can be roughly divided into orbit design and orbit optimization. The paper mainly focuses on the orbit design problem. We simply summarize of the previous works, and point out the main content of the on-orbit service spacecraft orbit design. We classify current on-orbit service spacecraft orbit design problem into parking-orbit design, maneuvering-orbit design and servicing-orbit design. Then, we give a detail description of the three specific orbits, and put forward our own ideas on the existed achievements.
