A highly accurate method for multi-term time fractional diffusion equation in two dimensions with ψ-Caputo fractional derivative

open access: yesResults in Applied Mathematics
In this study, the ψ-Caputo fractional derivative (as a generalization of the classical Caputo derivative where the fractional derivative is defined with respect to the function ψ) is considered to introduce a class of multi-term time fractional 2D ...

Generalized Hyers–Ulam Stability of Laplace Equation With Neumann Boundary Condition in the Upper Half‐Space

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 521-530, 30 January 2026.
ABSTRACT This paper investigates the generalized Hyers–Ulam stability of the Laplace equation subject to Neumann boundary conditions in the upper half‐space. Traditionally, Hyers–Ulam stability problems for differential equations are analyzed by examining the system's error, particularly in relation to a forcing term.

Disordered N‐termini enhance the thermostability of SGNH‐hydrolase family polyesterases

open access: yesProtein Science, Volume 35, Issue 1, January 2026.
Abstract Polyesters are widely used plastics that persist in the environment due to their resistance to degradation. Microbial polyesterases potentially offer recycling and remediation solutions. However, most polyesterases lack the thermostability and catalytic efficiency required for practical application.

Supercritical Pitchfork Bifurcation of a Fractional‐Order Doubly‐Fed Induction Generator

open access: yesEnergy Science &Engineering, Volume 13, Issue 12, Page 5970-5987, December 2025.
ABSTRACT To address the problem of the chaos phenomenon caused by the parameter drift of a doubly‐fed induction generator (DFIG) due to a changing operating environment, a fractional‐order stator voltage/flux‐oriented control model is developed, and bifurcation theory and numerical simulations reveal that the chaos mechanism originates from ...
