Based on gauge principle, quantum gauge theory of gravity, which is perturbatively renormalizable, is formulated in the Minkowski space-time. In quantum gauge theory of gravity, gravity is treated as a kind of fundamental interactions, which is transmitted by gravitational gauge field, and Dirac field couples to gravitational field through gravitational gauge covariant derivative. Based on this theory, we can easily explain gravitational phase effect, which has already been detected by COW experiment.展开更多

Nonverbal communication (NVC) is an essential component of human verbal communication. Sometimes it is even more powerful and expressive than verbal interactions, for they can convey such subtle feelings and fine emotions that verbal entries feel impotent of. This paper intends to make a survey on the notion of nonverbal communication and further explore the function and the significance of body language on remolding teachers' behaviors in foreign language teaching.展开更多

As is shown by the logic of argumentation and the relational logic of process- oriented constructivism, the development of intemational norms may take another approach, one of origination, diffusion and remolding. Through dialogues on norms, discourse critique, self-remolding and other means, China has enriched the practice of remolding international human rights norms with a human rights theory centered on the right to survive and develop, thereby providing a new approach and new angle of vision that allows non-Western countries to break away from the monist approach of norm development.展开更多

We also design a practical algorithm for the decomposition of thematrix triplet. As applications, we present necessary and suficient conditions for the existence of the generalsolutions to the system of matrix equations DXA = C1, EXB = C2, F XC = C3 and the matrix equation AXD + BY E + CZF = Gover F. We give the expressions of the general solutions to the system and the matrix equation when thesolvability conditions are satisfied. Moreover, we present numerical examples to illustrate the results of thispaper. We also mention the other applications of the equivalence canonical form, for instance, for the compressionof color images.展开更多

The interpolating currents are composed of a heavy diquaxk field and a light quark field. Contributions of the operators up to dimension six are taken into account in the operator product expansion. Within a reasonable error tolerance, our numerical results axe compatible with other theoretical predictions. This indicates that the diquaxk picture reflects the reality and is applicable to the study of doubly heavy baryons.展开更多
