a modified f-expansion method to find the exact traveling wave solutions of  two-component nonlinear partial differential equations (nlpdes) is discussed. we use this method to construct many new solutions to the nonlinear whitham-broer-kaup system (1+1)-dimensional. the solutions obtained include jacobi elliptic periodic wave solutions which exactly degenerate to the soliton solutions, triangu...

Artificial Fingertips Human fingertips with intricate structures and delicate perspiration system help people in gripping, climbing, or even more complex activities. In article number 2209729, Dirk J. Broer, Danqing Liu, co-workers report the design of a coating made cholesteric liquid crystal networks to mimic not only unique fingerprint topography but also secretion human fingertips. The biom...
