The comparison between China and UK of the construction of city community sports service system in the scope of eco-civilization

The construction of urban community sports public service is not only an important part of urban community public service management, but also an important content of building the national fitness public service system. In this paper, the author analyse the comparison between China and UK of the construction of city community sports service system in the scope of eco-civilization. With the rapid development of society and economy, people's demand for sports is more and more urgent, and community sports is the most effective and direct way to meet people's needs. Therefore, it has practical significance to study the construction and management mode of community sports facilities

Large Distance Modification of Newtonian Potential and Structure Formation in Universe

In this paper, we study the effects of super-light brane world perturbative modes on structure formation in our universe. As these modes modify the large distance behavior of Newtonian potential, they effect the clustering of a system of galaxies. So, we explicitly calculate the clustering of galaxies interacting through such a modified Newtonian potential. We use a suitable approximation for analyzing this system of galaxies, and discuss the validity of such approximations. We observe that such corrections also modify the virial theorem for such a system of galaxies.Comment: 13 pages, 3 captioned figure

Some new reactions of phosphonates.

The chemistry of a-ketophosphonates has been reviewed. New applications of a-ketophosphonates in synthesis are described. 1, 3-Diketoalkylphosphonates have been used to prepare phosphinyl - substituted heterocycles and imines derived from a-aminophosphonates have been used in syntheses of pyridyl phosphonates and in 1, 3-dipolar and carbanion additions to olefins. Acetylenic phosphonates have been prepared from a-phosphinylvinyl phosphates. The reactions of a-ketophosphonates with trialky phosphites are described; their use in 'ene' reactions has been investigated. N, N, N', N' -Tetramethylphenylphosphonic diamide has been ortho-lithiated and the resulting aryl-lithium reacted with a series of electrophiles. The Pummerer reaction intermediate from methyl diethoxy- phosphinylmethyl sulphoxide has been trapped with l-alkenes and the oxidative desulphurization of the products investigated

Face recognition accuracy of distinctive ways.

The continuous development of science and technology has led to the gradual digitization and intelligence of campus construction. To apply facial recognition technology to construct smart libraries in higher education, this study optimizes traditional facial recognition algorithm models. Firstly, a smart management system for university libraries is designed with facial recognition as the core, and secondly, the traditional FaceNet network is optimized. Combined with MobileNet, Attention mechanism, Receptive field module and Mish activation function, the improved multitask face recognition convolutional neural network is built and used in the construction of university smart library. The performance verification of the constructed model shows that the feature matching error value of the model in a stable state is only 0.04. The recognition accuracy in the dataset is as high as 99.05%, with a recognition error as low as 0.51%. The facial recognition model used in university smart libraries can achieve 97.6% teacher satisfaction and 96.8% student satisfaction. In summary, the facial recognition model constructed by this paper has good recognition performance and can provide effective technical support for the construction of smart libraries.</div
