Spintronics-based mesoscopic heat engine [PDF]
, 2012 We consider a nanowire suspended on two spin-polarized leads and subject to a nonuniform magnetic field. We show that in such a system a temperature drop between leads can significantly affect the nanowire dynamics. In particular, it is demonstrated that

Elastic Wave Properties of an Adaptive Electromechanical Metamaterial Beam
Shock and Vibration, 2020 An adaptive metamaterial beam with a couple of electromechanical resonators in each unit cell is proposed in this study to open Bragg bandgap or locally resonant bandgap for flexural wave attenuation in Euler–Bernoulli beams.

Nonlinear Dynamics of the High-Speed Rotating Plate
International Journal of Aerospace Engineering, 2018 High speed rotating blades are crucial components of modern large aircraft engines. The rotating blades under working condition frequently suffer from the aerodynamic, elastic and inertia loads, which may lead to large amplitude nonlinear oscillations ...

Initial Parameter Analysis about Resonant Orbits in Earth-Moon System
Advances in Astronomy, 2019 The initial parameters about resonant orbits in the Earth-Moon system were investigated in this study. Resonant orbits with different ratios are obtained in the two-body problem and planar circular restricted three-body problem (i.e., PCRTBP).
