To identify the effects of the expression levels of DNMT3a and DNMT3b, coding the de novo methyltransferases DNMT3a and DNMT3b, on 16 beef carcass and quality traits, 50 beef cattle liver and ribeye muscle tissue samples were collected. Quantitative real-time RT-PCR was employed to quantify the expression level of these two genes, and a basic model included(More)

A set of indicator screening method on evaluation index system of new socialist countryside (NSC) is established and its rationality was tested in this paper. First, a preliminary index system containing 44 indicators was put forward concerning farmer, agricultural and rural economic development. Then, combining with a series of subjective and objective(More)
Litter size and piglet mortality are important traits in pig production. The study aimed to identify quantitative trait loci (QTL) for litter size and mortality traits, including total number of piglets born (TNB), litter size at day 5 (LS5) and mortality rate before day 5 (MORT) in Danish Landrace and Yorkshire pigs by genome-wide association studies(More)
Dominance and imprinting genetic effects have been shown to contribute to genetic variance for certain traits but are usually ignored in genomic prediction of complex traits in livestock. The objectives of this study were to estimate variances of additive, dominance and imprinting genetic effects and to evaluate predictions of genetic merit based on genomic(More)
Low-latency detections of gravitational waves (GWs) are crucial to enable prompt follow-up observations to astrophysical transients by conventional telescopes. We have developed a low-latency pipeline using a technique called Summed Parallel Infinite Impulse Response (SPIIR) filtering, realized by a Graphic Processing Unit (GPU). In this paper, we exploit(More)
PPMLR-MHD is a new magnetohydrodynamics (MHD) model used to simulate the interactions of the solar wind with the magnetosphere, which has been proved to be the key element of the space weather cause-and-effect chain process from the Sun to Earth. Compared to existing MHD methods, PPMLR-MHD achieves the advantage of high order spatial accuracy and low(More)
