简介：AbstractCoronavirus disease 2019 (COVID-19) has rapidly swept around the globe since its emergence near 2020. However, people have failed to fully understand its origin or mutation. Defined as an international biosafety incident, COVID-19 has again encouraged worldwide attention to reconsider the importance of biosafety due to the adverse impact on personal well-being and social stability. Most countries have already taken measures to advocate progress in biosafety-relevant research, aiming to prevent and solve biosafety problems with more advanced techniques and products. Herein, we propose a new concept of biosafety chemistry and reiterate the notion of biosafety materials, which refer to the interdisciplinary integration of biosafety and chemistry or materials. We attempt to illustrate the exquisite association that chemistry and materials science possess with biosafety -science, and we hope to provide a pragmatic perspective on approaches to utilize the knowledge of these two subjects to handle specific biosafety issues, such as detection and disinfection of pathogenic microorganisms, personal protective equipment, vaccine adjuvants and specific drugs, etc.. In addition, we hope to promote multidisciplinary cooperation to strengthen biosafety research and facilitate the development of biosafety products to defend national security in the future.

简介：最近对在对称的锥上学习一些优化问题有许多兴趣。这份报纸在对称的锥(SCLP)上处理线性编程。这里的目的是扩大弄平牛顿算法解决SCLP的Qi-Sun-Zhous，在用乔丹代数学的对称的锥的描述为我们的分析形成基本基础的地方。由使用欧几里德几何学的乔丹代数学的理论，作者证明算法是全球性并且局部地在合适的假设下面二次地会聚。解决秒顺序锥编程的初步的数字结果也被报导。

简介：英语中的“仿词”是指因表达的需要，在某一个别场合或特殊情况下，临时仿制而成并加以使用的新词。分析专业英语第四册第一分册第三课中的5个仿词，就可以看到它对增强语言的表现力和表达效果的作用是很突出的。

简介：在这份报纸，一条直接概率的途径(DPA)被介绍为能是任何一个的环境负担激动的非线性的系统提出并且解决时刻方程一静止或nonstationary随机过程。建议方法有的优点从起始的条件和相应外部刺激的统计特征直接获得回答时刻。首先，回答时刻方程直接基于DPA被导出，它完全独立于它?后来，关于关联的特定的假设都不刺激组织的/filtering途径被做。由在Gaussian闭合下面解决他们，回答时刻能被获得。随后，为时刻方程的数字答案的一个多尺度的算法被利用改进计算效率并且避免许多墙钟时间。最后，有蒙特卡罗(MC)模拟的结果的比较给好同意。而且，多尺度的算法的优点被一个设计例子也以效率表明。
