Coding metasurfaces have found many applications in free space optics, but have not been used for integrated photonic applications.This can partly be attributed to the lack of implements to usefully implement such a framework in practice.The advent of low-loss phase change materials such as Sb2S3 has changed this by enabling the implementation Slee
Based on core description, thin section identification, X-ray diffraction analysis, scanning electron microscopy, low-temperature gas adsorption and high-pressure mercury intrusion porosimetry, the shale lithofacies of Shan23 sub-member of Permian Shanxi Formation in the east margin of Ordos Basin was systematically analyzed in this study.The Shan2
Competing hypotheses have been proposed to explain the subduction polarity of the Bangong-Nujiang Tethyan Ocean and the formation of the high-conductivity anomaly beneath the Qiangtang terrane.However, the lithospheric architecture of the northern Tibetan Plateau is still poorly understood due to inhospitable environments and topography.Therefore,
The rocking motion of two-wheeled suitcases is investigated.A rigid body mechanical model of the suitcase is constructed.All of the possible motion states (both wheels on the ground, one wheel Happy Camper Doormat on the ground, none of the wheels on the ground) are taken into account.The switching between the motion states is accomplished by a sim
