针对目前无人机反制技术存在的干扰功率高、易造成二次伤害等问题,提出一种基于软件无线电的全球卫星导航系统(global navigation satellite system,GnSS)欺骗方法。根据真实信号的发射时间、多普勒频率和导航电文等信息重构欺骗基带信号,并通过软件无线电平台将数字基带信号转变为射频信号,实现信号的播发。欺骗信号参数预测精度仿真结果表明,所提出的算法预测信号发射时间能达到小于10 ns的精度,预测多普勒频移能达到小于1 Hz的精度,验证了该欺骗方法的隐蔽性和可行性;实物实验结果表明,该欺骗系统能够有效进行授时、位置、轨迹欺骗。所提出的算法能够在软件无线电平台上实现隐蔽性较好的欺骗,具有成本低、实现简单、负面影响小等特点。

Refolding of reduced/denatured bovine pancreatic insulin with ion-exchange chromatography coupled with MALDI-TOF MS

引用

Chinese Chemical Letters 2009年第12期20卷 1487-1490页

作者： Cui e. Lin Quan B ai Institute of Modern Separation Science Key Laboratory of Synthetic and Natural Functional Molecule Chemistry of Ministry of Education Northwest University Xi'an 710069 China

The refolding of the reduced/denatured insulin from bovine pancreas as the model protein was investigated with weak anion exchange chromatography （WAX） coupled with MALDI-TOF MS. The results indicated that the disulfide bonds almost cannot be formed correctly with the common mobile phase by WAX. However, with the urea gradient elution and in the presence of GSSG/ Cyst as the ratio 1：6 in the mobile phase employed, the disulfide exchange of reduced/denatured insulin can be accelerated resulting in forming the correct three disulfide bonds. The protein refolding efficiency of reduced/denatured insulin can be increased from 3 % to 34%. The effects of urea gradient and the oxidant and reductant groups, such as GSSG/GSH, Cyst, and GSSG/Cyst, on the forming the disulfide bonds of reduced/denatured insulin were investigated in detail. The results were further tested by the separation of the WAX fraction of reduced/denatured insulin with RPLC and MALDI-TOF MS.

The Classical Binary and Triplet Distribution Functions for Dilute Relativistic Plasma

引用

natural Science 2015年第1期7卷 42-54页

作者： n. A. Hussein D. A. eisa e. G. Sayed Mathematics Department Faculty of Science Assiut University Assiut Egypt Mathematics Department Faculty of Science Assiut University New Valley Egypt

The aim of this paper is to calculate the binary and triplet distribution functions for dilute relativistic plasma in terms of the thermal parameter μ where , is the mass of charge;c is the speed of light;k is the Boltzmann’s constant;and T is the absolute temperature. Our calculations are based on the relativistic Bogoliubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy. We obtain classical binary and triplet distribution functions for one- and two-component plasmas. The excess free energy and pressure are represented in the forms of a convergent series expansions in terms of the thermal parameter μ.

Background:To develop and validate a deep learning-based approach to the fully-automated analysis of macaque corneal sub-basal nerves using in vivo confocal microscopy(IVCM).Methods:IVCM was used to collect 108 images from 35 macaques.58 of the images from 22 macaques were used to evaluate different deep convolutional neural network(Cnn)architectures for the automatic analysis of sub-basal nerves relative to manual *** remaining images were used to independently assess correlations and interobserver performance relative to three ***:Correlation scores using the coefficient of determination between readers and the best Cnn averaged *** inter-observer comparison,inter-correlation coefficients(ICCs)between the three expert readers and the automated approach were 0.75,0.85 and *** ICC between all four observers was 0.84,the same as the average between the Cnn and individual ***:Deep learning-based segmentation of sub-basal nerves in IVCM images shows high to very high correlation to manual segmentations in macaque data and is indistinguishable across *** quantitative measurements of corneal sub-basal nerves are important biomarkers for disease screening and management,the reported work offers utility to a variety of research and clinical studies using IVCM.
