应用紫外敏感器可较高精度地实现航天器全程自主导航。为解决其应用于中高轨不全程可见以及地心距测量误差大的问题,将紫外敏感器采用中心视场和环形视场同轴的结构,用中心视场观测地球,仅以地心方向矢量作为观测量降维输出,采用扩展卡尔曼滤波算法估计出航天器的位置和速度。对该方案建立算法模型,以轨道高度1 000~36 000 km的转移轨道为例仿真验证,研究测量精度、采样周期对导航精度的影响,分析系统可观性。仿真结果表明,系统可观,紫外敏感器测量精度越高导航精度越高,地心方向测量误差不大于0.05°时导航精度位置误差不超过4km、速度误差不超过0.5 m/s,方案有效可行。

长链非编码RNA(lncRNA)被定义为长度超过200个核苷酸并从人类基因组转录而未翻译(非编码)的RNA。随着人类基因组测序及图谱绘制的顺利完成,在随后启动的ENCODE研究中发现,约75%的基因组序列可以被转录成RNA,而其中大部分转录产物为非编码RNA。近年研究发现,lncRNA广泛参与生物个体的发育、细胞增殖、细胞分化等体内多种重要的生理及病理过程,如细胞周期调控、细胞代谢、细胞凋亡、诱导多能干细胞的重编程及表观遗传调控等生物学功能,而差异性表达对人类各种疾病的发生起着重要的作用,如恶性肿瘤、炎症及免疫性疾病等。研究表明lncRNA与眼科疾病的发病机制也密切相关,本文对近年来关于lncRNA的异常表达与眼部疾病的研究现状做一综述。
