Journal of Genetics and Genomics 2011年第11期38卷 505-513页

作者： linglin zhou Xueying Li Qi Liu Fangqing Zhao Jinyu Wu Institute of Genomic Medicine Wenzhou Medical College Wenzhou 325035 China Beijing Institutes of Life Science Chinese Academy of Sciences Beijing 100101 China

Over the past decade, there has been a growing realization that studying the small RNA transcriptome is essential for understanding the complexity of transcriptional regulation. With an increased throughput and a reduced cost, next-generation sequencing technology has provided an unprecedented opportunity to measure the extent and complexity of small RNA transcriptome. Meanwhile, the large amount of obtained data and varied technology platforms have also posed multiple challenges for effective data analysis and mining. To provide some insight into the small RNA transcriptome investigation, this review describes the major small RNA classes, experimental methods to identify small RNAs, and available bioinformatics tools and databases.

星地空间相干光通信中,受大气湍流及空间光耦合效率因素的影响,要实现高速率、高探测灵敏度的通信变得异常困难。针对星地空间相干光通信链路中空间光耦合较难的问题,提出了采用大面积平衡探测器来提高探测灵敏度的方法。通过分析平衡探测技术的原理及平衡探测器结构,设计了一种探测面直径为100μm、工作速率为5 Gbps的平衡探测器,搭建了空间相干光通信测试平台。在5 Gbps通信速率下,探测器的直接探测灵敏度达到-18.6 dBm,相干探测灵敏度达到-43.89 dBm,共模抑制比高于38.5 dB。测试结果验证了该空间光耦合平衡探测器用于空间相干光通信的可行性。
