锂电池异常状态监测的FEKF方法研究

为了保障锂离子电池的使用安全，提出了基于带渐消因子的扩展卡尔曼滤波 （Fading Extended Kalman Filter，FEKF）的电池状态在线监测方法. 建立锂电池一阶等效电路模型，利用递推最小二乘法进行锂电池状态参数在线辨识，建立状态方程；引入最优渐消因子，构造FEKF，得到端电压残差；使用端电压残差序列构造χ2分布的诊断函数，计算误检率与状态参数异常阈值. 实验结果显示利用FEKF生成的残差能更早对异常状态进行告警，证明FEKF能够显著提高χ2检验对锂电池内部缓变型异常状态判断的准确率.

Geochemistry of Clayey Aquitard Pore Water as Archive of Paleo-Environment,Western Bohai Bay

The record of paleo-environment in clayey aquitard pore water is much more effective relative to aquifer groundwater owing to the low permeability of clayey aquitard. Oxygen-18 (18O), deuterium (D), an...     

Variations on a theme: Clifford’s parallelism in elliptic space

In 1873, W. K. Clifford introduced a notion of parallelism in the three-dimensional elliptic space that, quite surprisingly, exhibits almost all properties of Euclidean parallelism in ordinary space. The purpose of this paper is to describe the genesis of this notion in Clifford’s works and to provide a historical analysis of its reception in the investigations of F. Klein, L. Bianchi, G. Fubini, and E. Bortolotti. Special emphasis is placed upon the important role that Clifford’s parallelism played in the development of the theory of connections.

水溶性La_(0.88)Sr_(0.12)MnO_3纳米粒子的非水相合成

采用纳米微乳液法,以三嵌段共聚物聚氧乙烯-聚氧丙烯-聚氧乙烯(PEO-PPO-PEO)为表面活性剂,乙酰丙酮镧(III),乙酰丙酮锰(III)和乙酰丙酮锶(II)为前驱体,1,2-十六烷二醇为还原剂成功合成了水溶性La0.88Sr0.12MnO3纳米粒子.FT-IR分析证实该纳米粒子表面存在PEO-PPO-PEO分子,XRD和TEM分析表明该纳米粒子基本上呈球形、粒径分布窄、结晶度高,VSM测试表明该纳米粒子室温下显示软铁磁性.纳米粒子在水中快速和高效的分散收集过程,表明该纳米粒子具有良好的水溶性和磁操控性.     

Whole genome sequencing as a means to assess pathogenic mutations in medical genetics and cancer

The past decade has seen the emergence of next-generation sequencing (NGS) technologies, which have revolutionized the field of human molecular genetics. With NGS, significant portions of the human genome can now be assessed by direct sequence analysis, highlighting normal and pathological variants of our DNA. Recent advances have also allowed the sequencing of complete genomes, by a method referred to as whole genome sequencing (WGS). In this work, we review the use of WGS in medical genetics, with specific emphasis on the benefits and the disadvantages of this technique for detecting genomic alterations leading to Mendelian human diseases and to cancer.
