Since early 2006, porcine epidemic diarrhea virus (PEDV) has been reemerging in immunized swine herds. Open reading frame 3 (ORF3) is the only accessory gene in the PEDV genome. The entire ORF3 genes of 12 PEDV field strains and one vaccine strain were sequenced. The ORF3 genes of Chinese PEDV field strains (excluding CH/GSJIII/07) contain a single 672- or(More)
The major structural protein of coronaviruses, the membrane (M) protein, can elicit the formation of protective antibodies, but little information is available about the M protein of porcine epidemic diarrhea virus (PEDV). Identification of epitopes on the PEDV M protein will be helpful in the elucidation of the antigenic properties of this protein. One(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) is an aetiological agent that can lead to reproductive failure and respiratory diseases of pigs. The replication and pathogenesis of PRRSV, although poorly understood, has been associated with the host factors. DDX18 is a member of DEAD-box RNA helicases (DDXs) family which were proved to(More)
Rig-space physics a finite element method(FEM) based simulation technique that aims at adding secondary motion on a character while maintaining seamless cooperation with traditional animation pipelines. We enhance the rig-space physics by introducing several techniques, including general field interaction, proportional-derivative control, and improved(More)
Shape interpolation, as a bridge communicating static geometries and dynamic shape sequences, is a fundamental operation in digital geometry processing and computer animation. We propose a fast asisometric-as-possible (AIAP) 3D mesh interpolation approach which casts the shape interpolation problem to finding an AIAP motion trajectory from the start shape(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) causes reproductive failures in sows and respiratory diseases in growing pigs, resulting in huge economic loss for the pig production worldwide. The nonstructural protein 9 (nsp9) and nonstructural protein 2 (nsp2) of PRRSV are known to play important roles in viral replication. Cellular(More)
Porcine reproductive and respiratory syndrome virus (PRRSV), the causative agent of PRRS, has two distinct and highly diverse genotypes (genotype 1 and genotype 2) in the field. Accurate diagnosis and differentiation of the two genotypes of PRRSV are critical to the effective prevention and control of PRRS. The non-structural protein 10 (Nsp10) plays a(More)
