OAM-based reconfigurable doppler shifts enable PAPR reduction for multi-carrier doppler diversity
Published 2023“…In a recent study, we discovered that even when the transceivers are stationary, a specific spatial Doppler shift can be generated by rotating the wavefront structure of the OAM helical beams. Furthermore, arbitrary integer rotational OAM Doppler shifts can be realized flexibly by using the recently popular digital encoding metasurfaces. …”

Small-scale wind energy harvesting using piezoelectric materials
Published 2015“…A two degree-of-freedom galloping piezoelectric energy harvester (GPEH) is proposed which successfully enhances the output power in low wind speeds. A beam stiffener is employed as an electromechanical coupling magnifier, which is proved to be an easy but greatly effective efficiency enhancing method for energy harvesting from VIV, flutter as well as galloping. …”

论李世民音乐政治观对儒家礼乐思想的继承和转化 = A study on Li Shimin music-politics: inheritance and transformation of Confucian ritual and music thought
Published 2014“…To a certain extent, he had inherited Yueji, Confucian ritual and Music thought - which extensively covers the social influence and educational function of music to society – while at the same time, his Music-politics thought bears much resemblance to those of Ji Kang. This article hopes to explore in detail Li Shimin’s Music-politics thought, and by using Yueji as a comparison, analyses how his inheritance and transformation of Confucian Ritual and Music thought played an important role in shaping the Tang Culture.…”
