Bimetric, conformal supergravity and its superstring embedding

Abstract We discuss the connection between Weyl2 supergravity and superstrings and further discuss holography between 4-dimensional, N $$ mathcal{N} $$ = 4 superconformal Weyl2 supergravity and N $$ mathcal{N} $$ = 8, higher spin-four theory on AdS 5.The Weyl2 plus Einstein supergravity theory is a special kind of a bimetric gravity theory and cons

A Study of Support Characteristics of Collaborative Reinforce System of U-Steel Support and Anchored Cable for Roadway under High Dynamic Stress

This paper presents a comprehensive study of the support effect and characteristics of a collaborative reinforce system of U-steel support and anchored cable (USS-AC) for roadway under high dynamic stress in a coal mine in China.The deformational behavior of the roadway and the load characteristics of reinforcing elements were Baby measured in real
