Programmable Metamaterials with Perforated Shell Group Supporting Versatile Information Processing
Advanced Science, EarlyView.This study proposes a novel mechanical metamaterial with high‐density memory based on multi‐stable perforated shells to realize multi‐layer information encoding, storage, decoding, and reading. The metamaterial can perform more application‐oriented tasks to process information, such as encryption and dynamic behavior regulation, which hopefully enables

Energy Dispersion Induced Precisely Tunable Friction of Graphitic Interface
Advanced Science, EarlyView.This study introduces a novel approach to precisely tune nanoscale friction on monolayer graphene using coupled DC/AC electric fields. Combining experiments (contact‐mode electrostatic force microscopy) and simulations (generalized Prandtl–Tomlinson model), vertical resonance is shown to disperse horizontal energy, reducing friction while preserving ...

Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity
Advanced Science, EarlyView.This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

Oscillation of Second-Order Nonlinear Delay Dynamic Equations with Damping on Time Scales
International Journal of Differential Equations, 2014 We use the generalized Riccati transformation and the inequality technique to establish some new oscillation criteria for the second-order nonlinear delay dynamic equation with damping on a time scale T(r(t)g(x(t), xΔ(t)))Δ+p(t)g(x(t), xΔ(t)) + q(t)f(x ...

An explicit unconditionally stable numerical method for solving damped nonlinear Schrödinger equations with a focusing nonlinearity [PDF]
SIAM J. Numer. Anal., Vol. 41, No. 4. pp. 1406-1426, 2003., 2003 This paper introduces an extension of the time-splitting sine-spectral (TSSP) method for solving damped focusing nonlinear Schr\"{o}dinger equations (NLS). The method is explicit, unconditionally stable and time transversal invariant. Moreover, it preserves the exact decay rate for the normalization of the wave function if linear damping terms are ...

Smooth attractors of finite dimension for von Karman evolutions with nonlinear frictional damping localized in a boundary layer [PDF]
arXiv, 2012 In this paper dynamic von Karman equations with localized interior damping supported in a boundary collar are considered. Hadamard well-posedness for von Karman plates with various types of nonlinear damping are well-known, and the long-time behavior of nonlinear plates has been a topic of recent interest.
