Butterfly-Inspired 2D Periodic Tapered-Staggered Subwavelength Gratings Designed Based on Finite Difference Time Domain Method by Wang, Houxiao, Zhou, Wei, Li, Er Ping, Mote, Rakesh Ganpat

“…The butterfly-inspired 2D periodic tapered-staggered subwavelength gratings were developed mainly using finite difference time domain (FDTD) method, assisted by using focused ion beam (FIB) nanoscale machining or fabrication. The periodic subwavelength structures along the ridges of the designed gratings may change the electric field intensity distribution and weaken the surface reflection. …”

Backbone boogie : dance the osteoporosis away! by Gey, Elainn Yee Rong, Lim, Cheryl Yi Xuan, Tan, Cammie Yi Jia

“…Based on the formative research gathered, reducing susceptibility to osteoporosis was found to be largely dependent on early prevention through a combination of calcium, vitamin D and regular weight-bearing exercise. Exercise was the least known aspect of osteoporosis prevention by the target audience and about 50% did not regularly exercise at all. …”

Secure image encryption based on an ideal new nonlinear discrete dynamical system by Lin, M. Rongming, Ng, Teng Yong

“…Extensive numerical experiment results have revealed that the proposed image encryption algorithm offers advantages of unlimited key space and high-level security, since those problematic periodic windows are no longer present within the key space, and it is extremely robust against known-plain-text attack, since the chaotic sequence generated bears no correlation whatsoever due to the folding effect of modulo operation. …”

Settlement behavior of shallow foundations in unsaturated soils under rainfall by Kim, Yongmin, Park, Hyundo, Jeong, Sangseom

“…The changes in the settlement during rainfall were also affected by the groundwater table position near the ground surface due to changes in matric suction. In addition, higher bearing capacity in response to rainfall infiltration was observed in the soil with smaller permeability function as compared to larger permeability function.…”
