In order to solve the problem of reflection cracks in semi-rigid base asphalt pavement, a study of temperature-type reflection crack expansion is carried out according to the typical climatic characteristics of Guilin, Guangxi Province.According to the theory of fatigue fracture mechanics, the stress intensity factor analysis at the crack tip is ca
We first derive the boundary theory from the U(1) Chern-Simons theory.The boundary action on an n-sheet manifold appears from its back-reaction of the Wilson line.The reason is that the U(1) Chern-Simons theory can provide an exact effective action when introducing the Wilson line.The Wilson line in the pure AdS3 Einstein gravity is equivalent to e
Abstract Background Cuticular hydrocarbons (CHC) have been documented to play crucial roles as species- and sex-specific cues in the chemical communication systems of a wide variety of insects.However, whether they Pants are sufficient by themselves as the sole cue triggering sexual behavior as well as preference of con- over heterospecific mating
Volcanic eruptions comprise an important airborne hazard for aviation.Although significant events are rare, e.g.compared to the threat of thunderstorms, they have a very high impact.The current state of tools and abilities to mitigate aviation hazards associated with an LED G8.5 assumed volcanic cloud was tested within an international demonstratio
The transitional faunas of the Permian Huqf succession Shaving Foam of Oman make it one of the key-sections for the intercalibration of Early to Middle Permian biostratigraphical scales.The abundance of fossils improved the knowledge of some marine faunas which populated the North-Eastern Gondwanan fringe during times of climatic changes in the Per
