噪声干扰对机载雷达系统效果评估和建模

选取干扰破坏因子作为评估标准,解决了自卫干扰和多架远距离支援干扰飞机下,多普勒噪声或调幅、调频噪声干扰对PD、脉冲机载雷达效果评估问题。在雷达方程和干扰方程基础上建立了数学模型,并用MATLAB实现,特别是远距离支援干扰考虑了斯韦林目标模型、大气、降雨影响,计算结果表明:不同的斯韦林目标模型下干扰破坏因子相同;噪声功率密度越大,干扰破坏因子就越大,即雷达探测距离减少的倍数增大。

Improved Non-Sieving Quadratic Sieve

In this paper, we give about prime numbers and Blum two theorems and one guess integers.We prove the two theorems about Blum integers.Combining the guess with the primitive non-sieving quadratic sieve,we proposed a improved non-sieving quadratic sieve（INQS）.In INQS,we not only reduce the times of squares and modulo n, but also imply another important conclusion,that is,we don＇t need to find the greatest common divisor of two integers as we do in PNQS.By some examples,we compare it with the primitive non-sieving quadratic sieve（PNQS）. It＇s faster to factor a integer by using improved non-sieving quadratic sieve than the primitive one.     

Towards genetic genome projects: genomic library screening and gene-targeting vector construction in a single step.

We have developed technologies that simplify genomic library construction and screening, substantially reducing both the time and the cost associated with traditional library screening methods and facilitating the generation of gene-targeting constructs. By taking advantage of homologous recombination in Escherichia coli, we were able to use as little as 80 bp of total sequence homology to screen for a specific gene from a genomic library in plasmid or phage form. This method, called recombination cloning (REC), takes only a few days instead of the several weeks required for traditional plaque-lift methods. In addition, because every clone in the mouse genomic library we have constructed has a negative selection marker adjacent to the genomic insert, REC screening can generate gene-targeting vectors in one step, from library screening to finished construct. Conditional targeting constructs can be generated easily with minimal additional manipulation.
