Study on a class of Schrödinger elliptic system involving a nonlinear operator [PDF]

open access: yes, 2020
This paper considers a class of Schrödinger elliptic system involving a nonlinear operator. Firstly, under the simple condition on and \u27, we prove the existence of the entire positive bounded radial solutions.

High Sensitivity Integrated Visible to Mid-Infrared Nonlinear Plasmonic Sensor

open access: yesIEEE Photonics Journal, 2017
We propose a Kretschmann-based nonlinear plasmonic sensor with a gold thin film deposited on a glass prism. Visible and mid-infrared signals are generated in this configuration through the nonlinear processes of sum- and difference-frequency generation ...

Nonnegative solutions for a system of impulsive BVPs with nonlinear nonlocal BCs [PDF]

open access: yes, 2014
We study the existence of nonnegative solutions for a system of impulsive differential equations subject to nonlinear, nonlocal boundary conditions. The system presents a coupling in the differential equation and in the boundary conditions. The main

Existence and uniqueness of positive solutions for a class of nonlinear fractional differential equations with mixed-type boundary value conditions [PDF]

open access: yes, 2018
In this article, we study a class of nonlinear fractional differential equations with mixed-type boundary conditions. The fractional derivatives are involved in the nonlinear term and the boundary conditions. By using the properties of the Green function,

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.
