We analysed the early viremia and clinical tests in 82 patients with epidemic hemorrhagic fever (EHF). The results showed that the changes in viremia and clinical tests are related to the severity of the disease and prognosis. Higher concentrations of the virus in infected patients might cause a more unfavourable prognosis and more abnormalities in clinical(More)
Plasmonic vortices (PVs) are generated by focusing a radially polarized optical vortex (OV) beam onto a metal surface. The intensity distribution of the PV is registered with a near-field scanning optical microscopy and agrees well with a theoretical prediction as well as numerical calculation. Beside the dark central spot, the numerical calculation also(More)
Kinetic changes of viremia were observed in 287 cases of hemorrhagic fever with renal syndrome (HFRS) in whom ribavirin was administered with double blind random control studied by means of virus isolation, indirect immunofluorescence assay and enzyme-linked immunosorbent assay. The positive rate of viremia was 79.7% (Sp = 3%) and positive rate of HERS IgM(More)
This paper presents an approach to research the active suspension system under LQG control strategy through the method of co-simulation using ADAMS and MATLAB. For this approach, the dynamic model of 1/2 automobile suspension system is created in the ADAMS, and then the LQG controller of suspension system is established by MATLAB, taking the vertical(More)
The selection of the network nodes and the optimization are very important aspects in wireless sensor networks. In this paper, we introduced briefly the basic principles of the algorithm first, and introduced the GB (grid-based) node choice algorithm amply. In succession, the performance for above algorithms was analyzed. Based on performance analysis, some(More)
Apply siRNA technology to take Smoothened (Smo) genetic locus, the possibility of Hhsignaling pathway, and also inhibits esophageal squamous carcinoma cell proliferation and induction of apoptosis. Utilizing SmosiRNA transfected esophageal squamous carcinoma EC9706 cells, adopting RT-PCR and Western blot technology to detect Smo, Gli1 mRNA and protein(More)
Over the last decades, the food safety issues become more and more important, such as BSE crisis, genetically modified organism (GMO) illegal spreading and melamine-contamination event. The food industry established a traceability system to reduce the impact of food safety issues, and the system became an effective method of guaranteeing the food safety.(More)
Glial cell line-derived neurotrophic factor (GDNF) mediates signaling across the cell membrane by interaction with the RET-GDNFR alpha receptor complex. We identified a family in which one member had medullary thyroid carcinoma (MTC) and four members had vesicoureteral reflux (VUR). Knowledge that mutations in the RET proto-oncogene cause MTC and studies(More)
This paper presents an improved adaptive genetic algorithm for integration optimization design of active vibration isolation system. During the operation of the algorithm, according to the individual fitness, the crossover rate and mutation rate make adaptive adjustments in accordance with the sigmoid function curve, and individuals of each generation are(More)
A new type of nonlinear waveguides, photorefractive surface optical waveguides is suggested, which can be induced by photorefractive surface waves on the boundary of photorefractive crystal. The disturbed refractive index distribution of such waveguides behaves as a periodic lattice with apodized envelope, thus we call them photorefractive surface apodized(More)
