High crystallinity of ZnWO4 nanoparticles has been successfully synthesized via a highly effective and environmentally friendly microwave route by controlling the reaction time and temperature. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and Fourier infrared spectrum (FT-IR). The crystallinity(More)
OBJECTIVE To investigate the gene-expression profile of chronic obstructive pulmonary disease (COPD) patients and explore the possible therapeutic targets. METHODS The microarray raw dataset GSE29133, including three COPD samples and three normal samples, was obtained from Gene Expression Omnibus. After data preprocessing with the Affy package, Student's(More)
The diameter of a cluster is the maximum intracluster distance between pairs of instances within the same cluster, and the split of a cluster is the minimum distance between instances within the cluster and instances outside the cluster. Given a few labeled instances, this paper includes two aspects. First, we present a simple and fast clustering algorithm(More)
A total of 24 children with cerebral palsy were enrolled in this study and underwent ultrasound guided transplantation of neural stem cells through the lateral ventricle. Neural stem cells (3.8 × 10(6)-7.3 × 10(7)) were injected into the lateral ventricles. Mild injury of lateral ventricular blood vessels occurred in only two cases (8.3%). Seven cases(More)
