We study the ratchet model with both thermal and potential fluctuations, discussing analytically the coherence resonance of the particle moving in such a potent
A suitable similarity transformation group is used to reduce the power law parabolic partial equation to a class of singular nonlinear boundary value problems.
The boundary diffraction wave theory is introduced to analyse a near-field diffraction (NFD) patte of a metallic probe tip of apertureless scanning near-field m
Ultrasonic P wave velocity (Vp) and quality factor (Qp value, on behalf of attenuation) in pyroxenite were presented as functions of pressures (0.3-3.0 GPa) and
We theoretically study the low temperature electron transport properties of a weak Rashba spin-orbit coupling (SOC) semiconductor quantum wire connected nonadia
