About the Benjamin-Bona-Mahony Equation in Domains with Moving Boundary

open access: yesTrends in Computational and Applied Mathematics, 2007
In this article, we prove the existence of solutions for an hyperbolic equation known as the Benjamin-Bona-Mahony equation. Our study involves increasing, decreasing, and mixed non-cylindrical domains and for this analysis, our main tools are the change ...

General Fractional Vector Calculus

open access: yesMathematics, 2021
A generalization of fractional vector calculus (FVC) as a self-consistent mathematical theory is proposed to take into account a general form of non-locality in kernels of fractional vector differential and integral operators.

Fredholmness of an abstract differential equation of elliptic type

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2004
In this work, we obtain algebraic conditions which assure the Fredholm solvability of an abstract differential equation of elliptic type. In this respect, our work can be considered as an extension of Yakubov's results to the case of boundary conditions ...

Capillary Surfaces in Non-Cylindrical Domains

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2000
This paper is concerned with the capillary problem in a class of non-cylindrical domains in K \subset \mathbb R^{n+1} obtained by scaling a bounded cross-section ­ \Omega \subset \mathbb R^n

Thermoelastic Analysis of Functionally Graded Cylindrical Panels with Piezoelectric Layers

open access: yesApplied Sciences, 2020
We propose a coupled thermoelastic approach based on the Lord-Shulman (L-S) and Maxwell’s formulations to study the wave propagation in functionally graded (FG) cylindrical panels with piezoelectric layers under a thermal shock loading.

Linear stability of certain translationally symmetric MHD equilibria with incompressible flow

open access: yesResults in Physics, 2017
In this paper, the linear stability analysis for ideal incompressible magnetohydrodynamic (MHD) flows is investigated. MHD flows in cylindrical domains with arbitrary cross-section as well as circular cross-section are considered.

Construction of a Right Inverse for the Divergence in Non-cylindrical Time Dependent Domains

open access: yesAnnals of PDE, 2023
AbstractWe construct a stable right inverse for the divergence operator in non-cylindrical domains in space-time. The domains are assumed to be Hölder regular in space and evolve continuously in time. The inverse operator is of Bogovskij type, meaning that it attains zero boundary values.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
