Stability of a Quartic and Additive Functional Equation in a 2-Banach Space
International Journal of Mathematics and Soft Computing, 2014 In this paper, we investigate the generalized Hyers-Ulam stability of the functional equation f(2x+y)+f(2x-y) = 4(f(x+y)+f(x-y))-3/7 (f(2y)-2f(y))+2f(2x)-8f(x) in 2-Banach space.

Journal of Food Science, Volume 91, Issue 6, June 2026.ABSTRACT Cellular aquaculture offers a sustainable solution to global seafood demand, yet the production of high‐value, whole‐cut fillets is hindered by the “texture gap,” the inability to replicate the complex, anisotropic architecture of native fish muscle and its collagenous myosepta.

From gateway to value ladder—The curious case of online mutual aid in China
Journal of Risk and Insurance, Volume 93, Issue 2, Page 349-387, June 2026.Abstract This study examines how InsurTech‐enabled information provision, specifically the disclosure of claimant information previously unavailable in conventional insurance, influences individuals' insurance uptake. We leverage Mutual Aid (MA) platforms as a natural context to examine how socially framed loss information, peer influence, and salience

On an improved restricted reverse weak‐type bound for the maximal operator
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract We obtain an improved lower bound for the restricted reverse weak‐type estimate of the Hardy–Littlewood maximal operator M$M$. This result is applied to the λ$\lambda$‐median maximal operator mλ$m_{\lambda }$ acting on a Banach function space X$X$.

Stable factorization of the Calderón problem via the Born approximation
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract In this article, we prove the existence of the Born approximation in the context of the radial Calderón problem for Schrödinger operators. The Born approximation naturally appears as the linear component of a factorization of the Calderón problem; we show that the nonlinear part, obtaining the potential from the Born approximation, enjoys ...

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks
Mathematical Methods in the Applied Sciences, Volume 49, Issue 8, Page 8095-8117, 30 May 2026.ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

Stability of Quadratic Mappings in 2-Banach Spaces and Related Topics
American Journal of Applied MathematicsFunctional analysis is an important branch of mathematics widely used to study the stability of different functional equations. This includes the stability of various quadratic functional equations, which typically involve a specific number of variables to reach results more easily in this field.
