Reconfigurable anomalous reflectors with stretchable elastic substrates at 140 GHz band by Kato Yuto, Yonemura Kazuma, Seki Kento, Kambara Retsuku, Sanada Atsushi

“…From full-wave simulations, we numerically confirm that highly efficient anomalous reflections with suppressed parasitic reflections in the undesired directions are achieved toward shallower angles as the substrate is stretched. We experimentally demonstrate that the proposed reflectors allow a dynamic control of the reflection direction with wide steering ranges of more than 20°. …”

Improvement of Specific Multi-target Tracking Algorithm in Cross-domain Environment by MU Xiaofang, LI Hao, LIU Jiaji, LIU Zhenyu, LI Yue

“…The difficulties of this task lie in the frequent occlusion between the objects in video frame, the unknown start and end time of the trajectory, the too small sized targets, the interactions between the objects, the apparent similarity, and the camera angle changes. In view of the frequent occlusions and apparent similar problems, an improved multiple target tracking algorithm is put forward. …”

Effect of Different Types of Middle Columns on the Seismic Performance of Single-Story Subway Station Structure by Sheng Li, Haiyang Zhuang, Wei Wang, Liguo Jin, Zhengfang Dong

“…This analysis model is further used to investigate the influence of different types of middle columns on the seismic response characteristics of the underground structure, such as the interstory displacement angle, seismic damage, and dynamic response. The results show that, compared with the rectangular columns, the circular columns with the equal moment of inertia suffer less damage in the earthquake and have better seismic performance. …”
