Scrub typhus is an acute infectious disease caused by Orientia tsutsugamushi that transmitted primarily through the bite of infected chigger mite larvae. The prevalence closely associated with environments characterized high moisture levels and abundant vegetation. This study documents first confirmed case scrub in Ningxia Hui Autonomous Region, China. patient presented characteristic clinical manifestations, including abnormal biochemical indicators positive serum-specific IgM antibodies...

With the country’s policy support and rapid development of Internet technology, domestic consumption level has been escalating structure changed. The traditional retail industry cannot integrate all relevant data due to security privacy protection concerns so that it is unable adjust sales strategies in an accurate timely manner. New sounded clarion call for revolution. supply chain demand forecasting important problem management. In this research, we propose a new commodity framework based...

Abstract The recessive genic male sterility (RGMS) method has several benefits in hybrid seed production; however, it is seldom employed industrial production owing to the difficulty of producing an ample number pure male-sterile seeds. In this study, we present efficient methodology for developing a two-line strategy produce through targeted mutation BnaMS1 and BnaMS2 conjunction with RUBY reporter Brassica napus. method, lines were successfully created directly from different elite...

Fluorescence diffuse optical tomography (FDOT) is an emerging imaging tool for in-vivo observation of organisms and small-animal. This modality retrieves the distribution concentration fluorescent biomarkers noninvasively quantitatively, which related to interior cellular molecular events. After FDOT system established, its performance parameters should be comprehensively systematically evaluated. paper conducts experimental study on such as spatial resolution sensitivity our system. The...

The perception layer of Internet Things (IOT) consists various sensors. It is the source IOT to identify objects and collect information. Information fusion collected from multi-sensor has been widely used in fields, such as intelligent industry, agriculture, transportation, environmental protection. In this paper, image fusion, multispectral (MS) panchromatic (PAN) images, studied, fused images are target detection, recognition, classification. However, traditional methods based on an...

Yersinia pestis , the bacterial causative agent of plague, remains an important threat to human health. Here we conducted genomic population and phylogenetic analyses using nucleotide polymorphisms (SNPs) 626 global whole-genome sequencing data reconstruct evolutionary history correlation between genetic groups plague foci. The phylogeographic diversity Y. in different kinds foci China showed host niches adaptation. Most natural strains are region-and focus-specific, with one main cluster...
