China Society for Human Rights Studies, I would like to extend my warm greetings to the launch of your Human Rights magazine. Enjoying human rights fully is a lofty goal long pursued after by human race. Over the years when they carried out revolution, construction and reforms, the Chinese people have struggled indomitably and strived incessantly to achieve this goal. Progress made in this regard has caught worldwide attention. When struggling for, safeguarding, promoting and developing human rights, the Chinese people have always combined the universality prin-

背景:运动对肠道菌群的调节与人体健康密切相关,但肠道菌群涉及多方面因素影响,国内外研究尚缺乏有关运动对大学生肠道菌群影响的较为一致的证据。目的:探讨运动对大学生肠道菌群多样性和物种组成的影响。方法:通过系统检索PubMed、Web of Science、Embase、Medline、Cochrane library、中国知网、万方、维普数据库,筛选后纳入8篇实证研究,对其采用半定量的方法进行分析。结果与结论:①在运动改变大学生肠道菌群物种多样性方面,高强度间歇训练和太极拳运动均能显著提升大学生肠道菌群的物种多样性,而有氧运动对大学生肠道菌群多样性的提升效果不显著;②在运动影响肠道菌群物种组成方面,3种运动方式均能显著改变大学生肠道中菌群的组成结构,可以提高瘤胃球菌、普氏粪杆菌、布劳提亚菌等有益菌的丰度,降低埃希氏菌属等有害菌的丰度;相较于高强度间歇训练,有氧运动和太极拳运动引起了更多有益菌丰度的提升;③除肠道菌群特征的变化外,运动还可以改善大学生体成分、心肺功能以及执行功能等,这些健康效益与运动引起的菌群变化密切相关,这些菌群可通过代谢调节、屏障功能以及神经调节对机体产生健康效益;④虽然目前已有研究证实了运动与肠道菌群存在关联,但运动影响肠道菌群的机制尚未明确,同时定位与宿主健康相关的菌群是未来以肠道菌群为治疗靶点的关键,这些均值得学者进一步关注和探究。

The malicious computer code immune system and the biological immune system are highly similar:both preserve the stability of the system in real time in a constantly changing environment. This similarity is exploited to design a malicious code immune system to solve the malware active defense problem. The malicious code immunization project is mainly composed of four major components: the immune information collection program,immune information filtering processing program, immunization information discrimination program, and immune response program. An imbalanced support vector machine method was applied to optimize output results of malicious code immunization, thereby removing uncertain malicious code immune outputs. This demonstrates in detail the feasibility of the imbalanced support vector machine method in optimizing the immunization program output data. We showed that an imbalanced support vector machines can optimize the outputs of the malicious code immune system by removing glitches from the outputs. As a result,the machine helps to determine the precise time of the emergence of the immune response.

This paper describes the calculation method for unsteady state conditions in the secondary air systems in gas turbines. The 1D-3D-Structure coupled method was applied. A 1D code was used to model the standard components that have typical geometric characteristics. Their flow and heat transfer were described by empirical correlations based on experimental data or CFD calculations. A 3D code was used to model the non-standard components that cannot be described by typical geometric languages, while a finite element analysis was carried out to compute the structural deformation and heat conduction at certain important positions. These codes were coupled through their interfaces. Thus, the changes in heat transfer and structure and their interactions caused by exterior disturbances can be reflected. The results of the coupling method in an unsteady state showed an apparent deviation from the existing data, while the results in the steady state were highly consistent with the existing data. The difference in the results in the unsteady state was caused primarily by structural deformation that cannot be predicted by the 1D method. Thus, in order to obtain the unsteady state performance of a secondary air system more accurately and efficiently, the 1D-3D-Structure coupled method should be used.

Modeling of the roughness in micro-nano scale and its influence have not been fully investigated, however the roughness will cause amplitude and phase errors of the radiating slot, and decrease the precision and efficiency of the SWA in Ku-band. Firstly, the roughness is simulated using the electromechanical coupled（EC） model. The relationship between roughness and the antenna＇s radiation properties is obtained. For verification, an antenna proto- type is manufactured and tested, and the simulation method is introduced. According to the prototype, a contrasting experiment dealing with the flatness of the radiating plane is conducted to test the simulation method. The advantage of the EC model is validated by comparisons of the EC model and two classical roughness models （sine wave and fractal function）, which shows that the EC model gives a more accurate description model for roughness, the maxi- mum error is 13%. The existence of roughness strongly broadens the beamwidth and raises the side-lobe level of SWA, which is 1.2 times greater than the ideal antenna. In addition, effect of the EC model＇s evaluation indices is investigated, the most affected scale of the roughness is found, which is 1/10 of the working wavelength. The proposed research provides the instruction for antenna designing and manufacturing.
