Gao, Yuan (author), Qiao, Tiezhu (author), Zhang, Haitao (author), Yang, Yi (author), Pang, Y. (author), Wei, Hongyan (author)During the operation of the belt conveyor, measuring speed of the belt conveyor is vital to the safe and efficient operation.

Wang, Yunwei (author), Wang, Yaping (author), Yu, Qian (author), Du, Zhiyun (author), Wang, Zhengbing (author), Gao, Shu (author)Tidal flats, where significant land‐ocean interactions take place, are often abstracted as a cross‐shore bed profile with sediment zonation from the lower sand flat to the upper mud flat. However, in addition to cross‐shore tidal currents, the impact of the alongshore components on cross‐shore sediment transport, morphological evolution, and...journal article 2019

Gao, Yisong (author), Wu, Lifang (author), Yan, Dong Ming (author), Nan, L. (author)In 3D printing, it is critical to use as few as possible supporting materials for efficiency and material saving. Multiple model decomposition methods and multi-DOF (degrees of freedom) 3D printers have been developed to address this issue. However, most systems utilize model decomposition and multi-DOF independently. Only a few existing...journal article 2019

Dong, H. (author), Gao, P. (author), Ye, G. (author)Drying of cement-based overlay systems is a critical issue, because it causes differential shrinkage between the overlay material and the concrete substrate and may induce cracking or debonding of the overlay material. In this paper the mechanisms of moisture transport in hydrating cement-based overlay systems are studied. A model is proposed...journal article 2019

Gao, P. (author), Ye, G. (author), Wei, J. (author), Yu, Q. (author)The HYMOSTRUC3D model has been used successfully to predict hydration and microstructure development of pure Portland cement paste. In recent years, a number of numerical models were proposed for optimizing the use of supplementary cementitious materials. Also HYMOSTRUC3D was extended for simulating the hydration and microstructure development...journal article 2019

(author), van der Tak, Floris (author), Gao, J.R. (author)Large heterodyne receiver arrays (~100 pixel) allow astronomical instrumentations to map more area within limited space mission lifetime. One challenge is to generate multiple local oscillator (LO) beams. Here, we succeeded in generating 81 beams at 3.86 THz by combining a reflective, metallic Fourier grating with an unidirectional antenna...journal article 2019

(author)The ubiquitous biomacromolecule DNA has an axial rigidity persistence length of ~50 nm, driven by its elegant double helical structure. While double and multiple helix structures appear widely in nature, only rarely are these found in synthetic non-chiral macromolecules. Here we report a double helical conformation in the densely charged...journal article 2019
