Analytical and Numerical Soliton Solutions of the Shynaray II‐A Equation Using the G′G,1G$$ \left(\frac{G^{\prime }}{G},\frac{1}{G}\right) $$‐Expansion Method and Regularization‐Based Neural Networks

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Nonlinear differential equations play a fundamental role in modeling complex physical phenomena across solid‐state physics, hydrodynamics, plasma physics, nonlinear optics, and biological systems. This study focuses on the Shynaray II‐A equation, a relatively less‐explored parametric nonlinear partial differential equation that describes ...

Explicit solutions of the fifth-order KdV type nonlinear evolution equation using the system technique

open access: yesResults in Physics, 2016
We consider the generalized fifth-order KdV type nonlinear evolution equation with variable coefficients. The system technique has been applied rigorously in order to find new exact solutions of the considered equations.

Supremacy Rule of Law in the Service of a Depoliticised Democracy—Pondering the Nature of the EU's ‘Social Contract’

open access: yesEuropean Law Journal, EarlyView.
ABSTRACT Seeing the EU roughly as a political system designed to remove the most essential political decisions from democratic control, while in a large part abiding by legal frameworks, we could speak about an opposition between technocratic legalism and democracy.

Justification of the NLS Approximation for the KdV Equation Using the Miura Transformation

open access: yesAdvances in Mathematical Physics, 2011
It is the purpose of this paper to give a simple proof of the fact that solutions of the KdV equation can be approximated via solutions of the NLS equation.

A systematic color correction pipeline for controlled‐environment imaging

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
ABSTRACT We present a stepwise color correction (CC) pipeline for controlled imaging environments. The workflow integrates flat‐field correction (FFC), gamma correction, and white‐balance correction, followed by a color‐mapping (CM) stage using machine‐learning regression—linear, partial least squares, and neural networks (NNs)—to deliver reliable CC ...

The simplified Hirota’s method for studying three extended higher-order KdV-type equations

open access: yesJournal of Ocean Engineering and Science, 2016
In this work we study three extended higher-order KdV-type equations. The Lax-type equation, the Sawada–Kotera-type equation and the CDG-type equation are derived from the extended KdV equation.

Computing the Solutions of the Combined Korteweg-de Vries Equation by Turing Machines [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
In this paper, we study the computability of the initial value problem of the Combined KdV equation. It is shown that, for any integer s>2, the nonlinear solution operator which maps an initial condition data to the solution of the Combined KdV ...

The Linearized Korteweg–de Vries Equation on the Line With Metric Graph Defects

open access: yesStudies in Applied Mathematics, Volume 156, Issue 4, April 2026.
ABSTRACT We study the small‐amplitude linearization of the Korteweg–de Vries equation on the line with a local defect scattering waves represented by a metric graph domain adjoined at one point. For a representative collection of examples, we derive explicit solution formulas expressed as contour integrals and obtain existence and unicity results for ...

On the Radius of Spatial Analyticity for the Quartic Generalized KdV Equation [PDF]

open access: yesAnnales de l'Institute Henri Poincare. Physique theorique, 2017
Lower bound on the rate of decrease in time of the uniform radius of spatial analyticity of solutions to the quartic generalized KdV equation is derived, which improves an earlier result by Bona, Grujić and Kalisch.
