Transformation and Identification between Two Generations Shanghai Dreams as a Political Melodrama
Xiaoping Wang
Mar 27, 2018
Shanghai Dreams (Qinghong青红), directed by Wang Xiaoshuai (王小帅,1966- ), is the first work created by a famed Chinese sixth-generation auteur to deal with the subject of construction of the “third line of defense” by focusing on...
Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs
The far-field profile of photonic quasi-crystal patterned and unpatterned LEDs, fabricated from commercial epitaxial substrates by electron beam lithography, has been measured prior to lapping and dicing. Emission enhancements...

Computation of three-dimensional flexural-gravity solitary waves in arbitrary depth
Fully-localised solitary waves propagating on the surface of a three-dimensional ideal fluid of arbitrary depth, and bounded above by an elastic sheet that resists flexing, are computed. The cases of shallow and deep water are...

Environmental Sustainability
Without embracing environmental sustainability (ES), the universal concept of Sustainable Development Goals (SDGs) cannot be achieved in today's world. As an inseparable part of SDGs, ES can help the nations to fulfil the goal...
Magnetization of YBCO film with ac travelling magnetic waves of relatively short wavelengths
W Wang, T Coombs
Aug 28, 2018
© 2017 Author(s). The magnetizations of the YBCO film with ac travelling magnetic waves of relatively short wavelengths were studied. The results have verified that the reported “intermediate value” of the superconducting...

Francis Burstall
Dec 31, 2019

 We characterise the maps into the space of 2-spheres in S n that are the conformal Gauss maps of conformal immersions of a surface into S n. In particular, we give an invariant formulation and efficient proof of a...
