BACKGROUND China, like other countries, is facing a growing burden of chronic disease but the prevalence of multimorbidity and implications for the healthcare system have been little researched. We examined the epidemiology of multimorbidity in southern China in a large representative sample. The effects of multimorbidity and other factors on usual source(More)
Deep level defects study of arsenic implanted ZnO single crystal Abstract of thesis entitled Zinc oxide has recently received great attention because of its potential applications in the fields of spintronics and optoelectronics. P-type doping is one of the greatest issues that have to be overcome for successfully developing ZnO based devices. Despite of(More)
This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Anthropogenic atmospheric emissions of typical toxic heavy metals have received worldwide concerns due to their adverse effects on human health and the ecosystem. By determining(More)
— We report on the low-frequency phase-noise measurements of AlGaN/GaN metal-oxide-semiconductor heterostructure field-effect transistors (MOS-HFETs) employing HfAlO as the gate dielectric. Some devices tested exhibited noise spectra deviating from the well-known spectrum. These devices showed broad peaks in the noise-spectral-density vs. frequency plots,(More)
