| 1 | Spatial and temporal analysis of tuberculosis in Zhejiang Province, China, 2009-2012显示文摘Background:Tuberculosis(TB)is an infectious disease of major public health concern.The disease has demonstrated large space-time variations.This study aims to explore the space-time dynamics of TB cases in an economically and geographically dynamic province in China with specific references of TB control for policy makers.Methods:Data on all reported TB cases from 2009 to 2012 were collected from the TB program at the Zhejiang Provincial Center for Disease Control and Prevention.We employed time series and exploratory spatial data analyses,including Moran’s I,Local Getis’s G_(i)^(*),and Kulldorff’s space-time scan statistics,to identify the temporal trends and spatial patterns of TB at a county level.Results:A total of 147,941 TB cases were reported during 2009–2012 in Zhejiang.A higher proportion of TB cases were younger,male,and registered permanent residents among all TB cases notified in the province.TB cases were reported most frequently in April with small peaks in June,July,and October.This disease was spatially clustering with Moran’s I values ranged from 0.29 to 0.32(p<0.001).A most likely cluster and ten secondary clusters were identified,mainly concentrated in the southeast and west counties of the province.Conclusions:This study identified seasonal patterns and significant space-time clusters of TB cases in Zhejiang,China.Poverty,migration,and seasonal effects may play important roles in potential clusters. | Erjia Ge Xin Zhang Xiaomeng Wang Xiaolin Wei | 2016 | Infectious Diseases of Poverty2016，5，1： | 13 |
| 2 | Electrolyte-gated transistors for neuromorphic applications显示文摘Von Neumann computers are currently failing to follow Moore’s law and are limited by the von Neumann bottleneck.To enhance computing performance,neuromorphic computing systems that can simulate the function of the human brain are being developed.Artificial synapses are essential electronic devices for neuromorphic architectures,which have the ability to perform signal processing and storage between neighboring artificial neurons.In recent years,electrolyte-gated transistors(EGTs)have been seen as promising devices in imitating synaptic dynamic plasticity and neuromorphic applications.Among the various electronic devices,EGT-based artificial synapses offer the benefits of good stability,ultra-high linearity and repeated cyclic symmetry,and can be constructed from a variety of materials.They also spatially separate“read”and“write”operations.In this article,we provide a review of the recent progress and major trends in the field of electrolyte-gated transistors for neuromorphic applications.We introduce the operation mechanisms of electric-double-layer and the structure of EGT-based artificial synapses.Then,we review different types of channels and electrolyte materials for EGT-based artificial synapses.Finally,we review the potential applications in biological functions. | Heyi Huang Chen Ge Zhuohui Liu Hai Zhong Erjia Guo Meng He Can Wang Guozhen Yang Kuijuan Jin | 2021 | Journal of Semiconductors2021，42，1： | 0 |
