Optimal control for a higher-order nonlinear parabolic equation describing crystal surface growth
Nonlinear Analysis, 2018 In this paper, we shall study the optimal control of the initial-boundary value problem of a higher-order nonlinear parabolic equation describing crystal surface growth. The existence and uniqueness of weak solutions to the problem are given.

Exact controllability of a second order integro-differential equation with a pressure term
Electronic Journal of Qualitative Theory of Differential Equations, 1998 This paper is concerned with the boundary exact controllability of the equation $$u''-\Delta u-\int_0^t g(t-\sigma)\Delta u(\sigma) d\sigma=-\nabla p$$ where $Q$ is a finite cilinder $\Omega\times]0,T[$, $\Omega$ is a bounded domain of $R^n$, $u=(u_1(x,t)

Chemistry – A European Journal, EarlyView.Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Despite its prevalence, research on binge‐eating disorder (BED) outcomes for residential treatment remains limited. To address this research scarcity, we evaluated changes in ED behaviors and comorbid symptoms, including depression and anxiety, for patients with BED that received residential eating disorder (ED) care from a ...
