Near-infrared single photon sources in telecommunication bands,especially at 1550 nm,are required for long-distance quantum communication.Here a down-conversion
In this paper, Ta/[NiFe(15 nm)/FeMn(10 nm)]/Ta exchange-biased bilayers are fabricated by magnetron sputtering, and their static and dynamic magnetic properties
A novel three-module robot has been introduced. It can change its configuration to adapt to the uneven terrain and to improve its tipover stability. This three-
This research of bidirectional pedestrian flows at signalized crosswalks is divided into two parts:model and applica-tion. In the model part, a mixed survey inc
