In this paper, we deduce the analytical form of many-body interatomic potentials based on the Green's function in tight-binding representation. The many-body potentials are expressed as the functions of the hopping integrals which are the physical origin of cohesion of atoms. For thesimple case of s-valent system, the inversion of the many-body potentials are discussed in detail by using the lattice inversion method. 展开更多

By describing the evolution of a quantum state with the trajectories of the Majorana stars on a Bloch sphere,Majorana’s stellar representation provides an intuitive geometric perspective to comprehend the quantum system with highdimensional Hilbert space.However,the representation of a two-spin coupling system on a Bloch sphere has not been solved satisfactorily yet.Here,a practical method is presented to resolve the problem for the mixed-spin(s,1/2)system and describe the entanglement of the system.The system can be decomposed into two spins:spin-(s+1/2)and spin-(s−1/2)at the coupling bases,which can be regarded as independent spins.Besides,any pure state may be written as a superposition of two orthonormal states with one spin-(s+1/2)state and the other spin-(s−1/2)state.Thus,the whole initial state can be regarded as a state of a pseudo spin-1/2.In this way,the mixed spin decomposes into three spins.Therefore,the state can be represented by(2s+1)+(2s−1)+1=4s+1 sets of stars on a Bloch sphere.Finally,some examples are given to show symmetric patterns on the Bloch sphere and unveil the properties of the high-spin system by analyzing the trajectories of the Majorana stars on the Bloch sphere. 展开更多

We consider the complex specializations of Krammer’s representation of the pure braid group on three strings, namely K(q,t), where q and t are non-zero complex numbers. We then specialize the indeterminate t by one and replace by for simplicity. Then we present our main theorem that gives us sufficient conditions that guarantee the irreducibility of the tensor product of two irreducible complex specializations of Krammer’s repre- sentations . 展开更多

Adding colors to monochrome thermal infrared images can help observers understand the scenery better. A nonlinear color estimation method for single-band thermal infrared imagery based on kernel principal component analysis (KPCA) and sparse representation was proposed. Nonlinear features of infrared image were extracted using KPCA. The relationship between image features and chromatic values was learned using sparse representation and a color estimation model was obtained. The thermal infrared images can be rendered automatically using the color estimation model. The experimental results show that the proposed method can render infrared image with an accurate color appearance. The proposed idea can also be used in other color estimation problem. 展开更多

The writers of this study are the Countess de Ségur,Louisa May Alcott and Maria Clarice Marinho Villac,from France,the United States and Brazil,respectively.It’s possible to identify a connection in their life trajectories―aristocratic and bourgeois families―and the ability to write their books.These publications address a specific audience,composed of children and young people,especially females.The representation of femininity in the narratives is related to the representation of family and religiosity,since it is up to the family to guide the girls in moral terms and this question is quite highlighted by religion.Analyzing the representation of femininity is due to the fact that the main books of female writers bring female protagonists,who exhibit a rebellious and mischievous behavior,which is observed and guided by adults.The representations of femininity is still valued and legitimized.For this reason,the narratives continue to be published and adapted to other languages,bringing to light these representations that remain until the 21st century in new clothing and updated vocabulary.Some adaptations for the Portuguese will also be analyzed,trying to identify longevity the works of these writers and their meaning in some epochs. 展开更多

This study's objective is to thoroughly analyze representations of teenage sexuality portrayed in two Chinese youths' films, which represent social, cultural, and historical diversities in China's Mainland, as well, to unfold some particular natures and trends of Chinese youth cinema in the context of globalization and internationalization. Content analysis and methodology of narrative explore the ideological nature of representations of youth as well as the interpretation of trends in Chinese youth cinema. This study argues the particular manners of representations of Chinese youth in the youths' films produced in China's Mainland, through distinct elements such as film properties, film discourse, and acting on set It will explain how functional and social category diversity, cultural diversity, and historical diversity derive the actuality in Chinese communities, and center on a series of sex-based issues that revel correlations between Chinese youths' ideology, psychology, and social construction. Including a discussion of technical factors, it defines the specific natures of Chinese youth cinema in the region based on fixed parameters of culture or ancestry that convey rhetorical messages to discover the characteristics of genre film so that the interpretation of the term "peers groups" represents the values and beliefs in modern Chinese society, thus presenting the exchange approaches which construct and validate the relationship among society, global film industry, young audience and film content. 展开更多

The Whole-Process People’s Democracy has become an important proposition of the socialist modernization democratic theory with Chinese characteristics,and has important value for the development of the new form of human civilization.The Whole-Process People’s Democracy is not only a“democracy”system,its focus is to achieve“people’s democracy”,its unique feature is to surpass“non process”democracy with the“Whole-Process”,and create a new governance path of a new form of human civilization.Of course,the emphasis of people’s democracy on the consciousness of people’s subjective participation in the whole process also puts forward corresponding requirements for the cultural quality construction of Chinese social citizens in the new era,so it is also of great significance to pay attention to the cultivation of citizens’public spirit. 展开更多

This was hardly possible in the past in China where the old feudalistic tradition dies hard. But this is really possible today when the common people cannot only sue officials and also get compensation if they are wronged. State compensation system It would be inevitable for government functionaries to cause damages to some citizens, legal persons or other organizations in the course of their management of the society. That is why China has established a State compensation system to compensate for the damages to citizens, legal persons and other organizations caused by government functionaries in exercising their power. 展开更多
