Two and three-dimensional slope stability reanalyses of Bukit Batok slope by Leong, Eng Choon, Rahardjo, Harianto

“…The 2D and 3D slope stability analyses on the slope that failed in 1989 showed that the average shear strength parameters of the residual soils are representative of the slope and the factors of safety obtained from 2D slope stability analyses are not necessarily more conservative than 3D slope stability analyses. …”

An artificial neural network model for multi-flexoelectric actuation of plates by Fan, Mu, Yu, Pengcheng, Xiao, Zhongmin

“…Flexoelectric effect can be used to design actuators to control engineering structures including beams, plates, and shells. Multiple flexoelectric actuators method has the advantage of less stress concentration and better control effect, but the mode-dependent optimal actuator locations could influence the flexoelectric actuation effect significantly. …”

Large eddy simulations of turbulent circular wall jets by Zhang, Shuai, Law, Adrian Wing-Keung, Zhao, Bing

“…Overall, the study shows that LES coupling with proper near-wall modelling can simulate both the kinematic and mixing characteristics of the turbulent wall jet in a satisfactory manner, and the accuracy is superior to the RANS models with enhanced wall functions for this three-dimensional wall-bounded shear flow. The advantages can be attributed directly to the better simulations of the anisotropic jet spreading near the wall.…”

Self-organized canals enable long-range directed material transport in bacterial communities by Li, Ye, Liu, Shiqi, Zhang, Yingdan, Seng, Zi Jing, Xu, Haoran, Yang, Liang, Wu, Yilin

“…Using Pseudomonas aeruginosa colonies as a model system, we discover that a large-scale and temporally evolving open-channel system spontaneously develops in the colony via shear-induced banding. Fluid flows in the open channels support high-speed (up to 450 µm/s) transport of cells and outer membrane vesicles over centimeters, and help to eradicate colonies of a competing species Staphylococcus aureus. …”
