A Novel Analysis of Oscillatory Properties in Nonlinear Differential Equations With Damping Terms and Advanced Arguments

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This research investigates the oscillatory behavior of a class of second‐order nonlinear advanced differential equations with a damping term. Sufficient conditions for the oscillation of all solutions were obtained using the Riccati transform and comparison techniques with first‐order advanced differential inequalities. The new results are more general

Nonlinear oscillations in disconjugate forced functional equations with deviating arguments

International Journal of Mathematics and Mathematical Sciences, 1983
For the equation Lnv(t)+a(t)h(y(g(t)))=f(t) where Lny(t)=pn(t)(pn−1(t)(…(p1(t)(po(t)y(t))′)′…)′)′ sufficient conditions have been found for all of its solutions to be oscillatory.

A Hybrid Fitted Mesh Numerical Scheme for Solving Singularly Perturbed Reaction–Diffusion Equation With Mixed Shifts

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study develops a robust hybrid numerical scheme for a class of time‐dependent, singularly perturbed differential‐difference equations characterized by a small positive parameter multiplying the highest order derivative term and mixed spatial shifts (delay and advance) in the reaction terms.

Exact Solitary Wave Solutions in Nonlinear Carbon Nanotube Composite Beams on Viscoelastic Foundations Under M‐Truncated Derivative

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this study, the nonlinear partial differential equation that governs the free vibration of a carbon nanotube composite beam is analytically investigated using the truncated M‐fractional derivative. This model is a beam supported by a nonlinear viscoelastic base and reinforced by carbon nanotubes.

Oscillation of solutions to second-order nonlinear differential equations of generalized Euler type

Electronic Journal of Differential Equations, 2013
We are concerned with the oscillatory behavior of the solutions of a generalized Euler differential equation where the nonlinearities satisfy smoothness conditions which guarantee the uniqueness of solutions of initial value problems, however, no ...

Oscillation and nonoscillation theorems for some mixed difference equations

International Journal of Mathematics and Mathematical Sciences, 1992
In this paper we investigate the oscillatory and nonoscillatory behavior of solutions of certain mixed third and fourth order difference equations. Specific results are also obtained for the constant coefficient cases.

Manipulator Control Using CSRT Algorithm in Image‐Based Visual Servoing Technique and ROS 2 Tools

Journal of Robotics, Volume 2026, Issue 1, 2026.
Achieving precise robotic manipulation is difficult when objects are unknown or not pretrained, and the environment is unpredictable. Traditional cameras often struggle with depth perception and lag when a robot gets close to its target. To address these limitations, this study explores the design and implementation of an image‐based visual servoing ...

Dynamics of Downdrafts Around a Growing Convective Cloud: A Numerical Study

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract We examine the dynamics of cloud‐edge downdrafts over the growth phase of isolated cumuli, combining Eulerian and Lagrangian analyses. As in previous studies, our results show that growing cumuli are surrounded by downdrafts linked to cloud‐scale quasi‐toroidal circulations at all times at middle and upper cloud levels consistent with the ...

Oscillatory and nonoscillatory solutions of multivalued differential inclusions

Computers & Mathematics with Applications, 2005
The paper concerns the existence of Carathéodory solutions to the ``scalar'' differential inclusion \(y'(t)\in F(t,y(t))\) subject to the constraints \(\alpha(t)\leq y(t)\leq\beta(t)\) (if \(\alpha\) and \(\beta\) are oscillatory functions, then so is \(y\)). The hypotheses must be added that \(\alpha\) and \(\beta\) are absolutely continuous (for the `
