How Nonlinear Can Nonlinear Be? [PDF]

open access: yes, 1993
The development of the subject of nonlinear acoustics has been described in some detail in previous QNDE volumes. [1, 2, 3]· The subject, however, continues to grow and to expand. Therefore, it is as difficult to define an end to the subject as it was to define a beginning.

High‐Fat and Low‐Carbohydrate Dietary Environments Are Linked to Reduced Idiopathic Epilepsy Incidence and Prevalence

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Dietary manipulations like ketogenic diets are established interventions for recalcitrant epilepsy. However, it remains unknown whether specific macronutrient exposure through dietary environments could possibly extend to primary preventive qualities, associated with changes in epilepsy disease burden (prevalence and incidence).

A machine learning based Bayesian optimization solution to nonlinear responses in dusty plasmas [PDF]

open access: yesarXiv, 2020
Nonlinear frequency response analysis is a widely used method for determining system dynamics in the presence of nonlinearities. In dusty plasmas, the plasma-grain interaction (e.g., grain charging fluctuations) can be characterized by a single particle nonlinear response analysis, while grain-grain nonlinear interactions can be determined by a multi ...

Two-mode Nonlinear Coherent States [PDF]

open access: yesOptics Communications 178(4-6)(2000)365-369, 2000
Two-mode nonlinear coherent states are introduced in this paper. The pair coherent states and the two-mode Perelomov coherent states are special cases of the two-mode nonlinear coherent states. The exponential form of the two-mode nonlinear coherent states is given.

Nonlinearity in a dynamo [PDF]

open access: yesGeophysical & Astrophysical Fluid Dynamics, 2010
Using a rotating flat layer heated from below as an example, we consider effects which lead to stabilizing an exponentially growing magnetic field in magnetostrophic convection in transition from the kinematic dynamo to the full non-linear dynamo. We present estimates of the energy redistribution over the spectrum and helicity quenching by the magnetic

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

Nonlinear gauge transformation for a class of Schroedinger equations containing complex nonlinearities [PDF]

open access: yesRep. Math. Phys. 46, 113 (2000), 2002
We consider a wide class of nonlinear canonical quantum systems described by a one-particle Schroedinger equation containing a complex nonlinearity. We introduce a nonlinear unitary transformation which permits us to linearize the continuity equation.

A Nonlinear Adiabatic Theorem for Coherent States [PDF]

open access: yesNonlinearity 24, 8 (2011) 2143-2164, 2010
We consider the propagation of wave packets for a one-dimensional nonlinear Schrodinger equation with a matrix-valued potential, in the semi-classical limit. For an initial coherent state polarized along some eigenvector, we prove that the nonlinear evolution preserves the separation of modes, in a scaling such that nonlinear effects are critical (the ...
