<i>Geometry compression</i> is the coding of 3D geometric data in a form that requires less space to store and less bandwidth to transmit. <i>Animated geometry compression</i> is the compression of temporal sequences of geometric data. An octree-based motion representation method in which a small set of motion vectors are generated for each frame by(More)
BACKGROUND Association studies have been employed to investigate the relationships between host single nucleotide polymorphisms (SNPs) and susceptibility to pulmonary Tuberculosis (PTB). However, such candidate genetic markers have not been widely studied in Chinese population, especially with respect to the disease development from latent M. tuberculosis(More)
In this paper we propose a model to predict the performance of synchronous discrete event simulation. The model considers parameters including the number of active objects per cycle, event execution granularity and communication cost. We derive a single formula that predicts the performance of synchronous simulation.We have benchmarked several VHDL circuits(More)
Computer visualization and animation have been used in computer science education to help students better understand the concepts. This paper presents an animated simulator for packet sniffer and its use in a network security course. The animated packet sniffer simulator was designed to demonstrate graphically the security concept packet sniffer and related(More)
Using animated visualization tools has been an important teaching approach in computer science education. We have developed three visualization and animation tools that demonstrate various information security concepts and actively engage learners. The information security concepts illustrated include: packet sniffer and related computer network concepts,(More)
Wikipedia, a User Innovation Community (UIC), is becoming increasingly influential source of knowledge. The knowledge in Wikipedia is produced and processed collaboratively by UIC. The results of this collaboration process present various seemingly complex patterns demonstrated by update history of different articles in Wikipedia. Agent simulation is a(More)
Hepatitis B virus (HBV) DNA is prone to mutations because of the proofreading deficiencies of HBV polymerase. The postoperative prognostic value of HBV mutations in HBV X protein (HBx) gene was assessed in HBV associated hepatocellular carcinoma (HCC) patients. The HBx gene was amplified and sequenced, the HBV mutations was identified according to NCBI(More)
The accumulation of single nucleotide polymorphisms (SNPs) in the displacement loop (D-loop) of mitochondrial DNA (mtDNA) has been described in various types of cancers, and their association with cancer risk and disease outcome has been extensively identified. In the present study, we investigated the association between age-at-onset and SNPs in the(More)
