Plasma Brain Dynamics (PBD): A Mechanism for EEG Waves Under Human Consciousness [PDF]
, 2017 EEG signals are records of nonlinear solitary waves in human brains. The waves have several types (e.g., α, β, γ, θ, δ) in response to different levels of consciousness. They are classified into two groups: Group-1 consists of complex storm-like waves (α,

He–Laplace method for nonlinear vibration in shallow water waves
Journal of Low Frequency Noise, Vibration and Active Control, 2019 This study is based on an analytical approach for nonlinear vibration of nonlinear evaluation equations which arises in shallow water waves. This approach is, coupled with variational iteration method and Laplace transformation, known as He–Laplace ...

The gravitational-wave memory effect
, 2010 The nonlinear memory effect is a slowly-growing, non-oscillatory contribution to the gravitational-wave amplitude. It originates from gravitational waves that are sourced by the previously emitted waves.

Internal solitary wave transformation over the slope: Asymptotic theory and numerical simulation
Journal of Ocean Engineering and Science, 2018 The propagation and evolution of long nonlinear internal solitary waves over slope-shelf topography is theoretically and numerically studied in a two-layer fluid system of finite depth. The variable Korteweg–de Vries (vKdV) and variable extended Korteweg–

Nonlinear acoustic–gravity waves
Journal of Plasma Physics, 2009 AbstractPrevious results on nonlinear acoustic–gravity waves are reconsidered. It turns out that the mathematical techniques used are somewhat similar to those already adopted by the plasma physics community. Consequently, a future interaction between physicists in different fields, e.g. in meteorology and plasma physics, can be very fruitful.
