The new MPEG-21 standard defines a multimedia framework to enable transparent and augmented use of multimedia resources across heterogeneous networks and devices used by different communities. In this paper, we incorporated the perceived motion energy (PME) model into the proposed MPEG-21 digital item adaptation framework for frame dropping in H.264 encoded(More)
Liver fibrosis is characterized by an exacerbated accumulation of deposition of the extracellular matrix (ECM), and the activation of hepatic stellate cells (HSC) plays a pivotal role in the development of liver fibrosis. Periostin has been shown to regulate cell adhesion, proliferation, migration and apoptosis; however, the involvement of periostin and its(More)
The receptor for advanced glycation end products (RAGE) and the angiotensin II type I receptor (AT1R) have been separately linked to the pathogenesis of diabetic atherosclerosis. However, no prior study has addressed a linkage between RAGE and AT1R in diabetic atherogenesis. Therefore, we tested the hypothesis that upregulation of the ligand-RAGE axis via(More)
Calcium channel blockers (CCBs) have been shown to improve clinical outcomes in atherosclerotic vascular disease. The mechanisms underlying the vasculoprotective effects of a third-generation calcium channel blocker, azelnidipine, are incompletely understood. We asked whether azelnidipine attenuates atherosclerosis in monkeys and mice beyond its blood(More)
We developed a highly sensitive method to detect liver tissue stiffness with atomic force microscopy (AFM), and investigated the physical features of hepatocarcinogenesis. Wistar rats received weekly intraperitoneal injections of diethylnitrosamine (DEN) or saline (control) followed by a 2-week wash-out period. Liver samples were harvested at 10, 14, or 18(More)
— Enterprise level software is implemented using multi-layer architecture. These layers are often implemented using de-coupled solutions with millions of lines of code. Programmers often have to track and debug a function call from user interface layer to the data access layer while troubleshooting an issue. They have to inspect the code based on search(More)
This paper examines use of dynamic probabilistic networks (DPN) for human action recognition. The actions of lifting objects and walking in the room, sitting in the room and neutral standing pose were used for testing the classification. The research used the dynamic interrelation between various different regions of interest (ROI) on the human body (face,(More)
IPTV based E-Learning is an attractive and promising service for the widespread of TV devices and potential consumers. Especially in rural area in China, it is more useful than traditional web-based learning application for the lack of computers. However, the transition from traditional web-based Learning system to IPTV-based learning is not trivial for the(More)
For the problem of low detection accuracy and slow speed to fast motion object, when solving the basic optical flow constraint equation with the traditional algorithm, an improved optical flow algorithm based on LK optical flow algorithm has been put forward in this paper. The intensive optical flow is the biggest characteristic of the algorithm, the(More)
This paper illustrated the design and implementation of a distributed learning resource registry system. This system faces the challenge that e-learning users can hardly find out their interested learning resources in current distributed and relatively isolated environment where Web-based learning contents are stored in different resource repositories or(More)
