Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...

Unravelling vicious circles of land use competition and food insecurity in agropastoral rangelands

People and Nature, EarlyView.
Abstract In many regions of the world, the adoption of new livelihood strategies that compete with traditional strategies is one driver of competition over land, resulting in unforeseen impacts on the livelihoods of land users and accelerating land degradation. One example is the Borana Zone in southern Ethiopia, where the expansion of crop cultivation

Comparative Analysis of the Performances of a Nonlinear Observer and Nonlinear Kalman Filters in the Presence of Non‐Gaussian Disturbances

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper focuses on state estimation for a fairly general class of systems, involving nonlinear functions and disturbances in both the process dynamics and output equations. A nonlinear observer that satisfies a H∞$$ {\boldsymbol{H}}_{\boldsymbol{\infty}} $$ disturbance attenuation constraint in addition to providing asymptotic stability in ...

Unlocking Klockmannite: Formation of Colloidal Quasi‐2D CuSe Nanocrystals and Photo‐Physical Properties Arising From Crystal Anisotropy

Small, EarlyView.
Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...

Nonlocal fractional differential inclusions with impulses at variable times

Surveys in Mathematics and its Applications, 2019
By utilizing the measure of noncompactness, multivalued fixed point theory, and fractional calculus, the authors obtain the existence of mild solutions for a fractional semilinear differential inclusions with nonlocal conditions and impulses at variable times. Moreover, the topological properties of the solution set are investigated. Some known results
