云南省2013-2015年间部分猪场猪瘟感染情况调查
Heilongjiang Animal Science and Veterinary Medicine(2017)
Abstract
了解云南省部分猪场猪瘟发病情况,为猪场制订合理的防控规程提供依据,采用RT-PCR方法对20132015年间云南省部分猪场1 055份样品进行了猪瘟病毒(CSFV)的病原检测.结果表明:2013-2015年猪瘟病毒阳性率分别为7.20%、17.65%、12.26%,三年间猪瘟参与混合感染占总混合感染的比例分别为37.5%、46.4%、67.4%.说明在云南省境内部分猪场猪瘟的发病率仍然很高,有的猪场甚至在使用疫苗后仍然发病.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
