Theory of small aspect ratio waves in deep water
(Elsevier B.V., 2005-11-15)
In the limit of small values of the aspect ratio parameter (or wave steepness) which measures the amplitude of a surface wave in units of its wave-length, a model equation is derived from the Euler system in infinite depth ...

Normative data of F-wave measures in China
(Elsevier B.V., 2013-01-01)
Objective: To establish normal ranges of F-wave measures in China as compared to published data in Brazil and Japan.Method: We studied F waves in 127 healthy Chinese subjects, aged 21-78 years old, stimulating the median, ...
Transmission and Reflection of Strongly Nonlinear SolitaryWaves at Granular Interfaces
(Amer Physical Soc, 2013-03-23)
The interaction of a solitary wave with an interface formed by two strongly nonlinear noncohesive granular lattices displays rich behavior, characterized by the breakdown of continuum equations of motion in the vicinity ...
THE OUTGOING TIME-HARMONIC ELASTIC WAVE IN A HALF-PLANE WITH FREE BOUNDARY
(SIAM PUBLICATIONS, 2011)
Under a time-harmonic assumption, we prove existence and uniqueness results for the outgoing elastic wave in an isotropic half-plane, where the source is given by a local normal stress excitation of the free boundary. This ...
On exact boundary controllability for linearly coupled wave equations
(Academic Press Inc. Elsevier B.V., 2011-09-15)
In this paper we study exact boundary controllability for a system of two linear wave equations coupled by lower order terms. We obtain square integrable control of Neuman type for initial state with finite energy, in ...

Stabilization of linear ion beam right-hand polarized instabilities by nonlinear Alfvén/ion-cyclotron waves
(Blackwell Publishing Ltd, 2003)
It is shown that ion-beam plasma electromagnetic right-hand polarized instabilities can be stabilized by nonlinear left-hand polarized waves. This phenomenon constitutes a nonlinear saturation mechanism for right-hand ...
Sound waves and solitons in hot and dense nuclear matter
(ELSEVIER SCIENCE BV, 2009)
Assuming that nuclear matter can be treated as a perfect fluid, we study the propagation of perturbations in the baryon density. The equation of state is derived from a relativistic mean field model, which is a variant of ...
