An outbreak of diarrhea in pigs started in Guangdong, South China in January 2011. Cases were characterized by watery diarrhea, dehydration and vomiting, with 80–100% morbidity and 50–90% mortality in suckling piglets. The causative agent of the diarrhea was ultimately identified as porcine epidemic diarrhea virus (PEDV). In this study, we isolated a PEDV(More)
Physical-layer Network Coding (PNC) can significantly improve the throughput of two-way relay channels. An interesting variant of PNC is Analog Network Coding (ANC). Almost all ANC schemes proposed to date, however, operate in a symbol by symbol manner (memoryless) and cannot exploit the redundant information in channel-coded packets to enhance performance.(More)
A porcine reproductive and respiratory syndrome virus (PRRSV) QY1 was serially passed on Marc-145 cells. Virulence of different intermediate derivatives of QY1 (P5, P60, P80, and P100) were determined. The study found that QY1 had been gradually attenuated during the in vitro process. Pathogenicity study showed that pigs inoculated with QY1 P100 and P80 did(More)
Interference between adjacent body area networks (BANs), leading to dramatic performance degradation of the whole system, is always an unsolved issue. In this paper, we study the interference game in which BANs adjust their resource allocation strategies to avoid putting highly interfering sensors into the same time slots. Dickhaut-Kaplan algorithm is used(More)
In this paper, the authors derive a symbol error rate expression for the M-ary TH-PPM UWB system under the interference from multiple users. Monte Carlo simulations are then used to validate the analytical solutions. Moreover, the analytical results are compared to those found by Gaussian approximation. The authors further show that compared to a binary(More)
