Positive solutions of a boundary value problem with integral boundary conditions

Electronic Journal of Differential Equations, 2011
We consider boundary-value problems studied in a recent paper. We show that some existing theory developed by Webb and Infante applies to this problem and we use the known theory to show how to find improved estimates on parameters $mu^*, lambda ...

Hierarchically Porous Heteroatom‐co‐Doped Carbons for Enhanced Carbon Dioxide Capture

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Polythiophene‐derived N,S‐co‐doped carbons with tailored surface functionalities exhibit enhanced CO₂ adsorption. The efficiency of carbon dioxide (CO2) adsorption in carbonaceous materials is primarily influenced by their microporosity and thermodynamic affinity for CO2.

Approximate controllability of Sobolev type fractional evolution systems with nonlocal conditions

, 2017
In this paper, we study the approximate controllability of Sobolev-type fractional evolution systems with non-local conditions in Hilbert spaces. Sufficient conditions of approximate controllability of the desired problem are presented by supposing an ...

A seamless local-nonlocal coupling diffusion model with $H^1$ vanishing nonlocality convergence [PDF]

arXiv
Based on the development in dealing with nonlocal boundary conditions, we propose a seamless local-nonlocal coupling diffusion model in this paper. In our model, a finite constant interaction horizon is equipped in the nonlocal part and transmission conditions are imposed on a co-dimension one interface.

Solar Energy Storage Optimization Using Fractional Derivative Simulations of Maxwell Hybrid Nanofluid Flow: Entropy Generation Analysis

Energy Science &Engineering, EarlyView.
ABSTRACT This attempt examines the heat transfer enhancement from unsteady bioconvective Maxwell nanofluid flow under the incidence of solar radiation influenced by viscous dissipation and chemical reaction through a porous medium. The nanofluid contains silver and titanium alloy hybrid nanoparticles with gyrotactic micro‐organisms in ethylene glycol ...

Alexandrov Theorem for nonlocal curvature [PDF]

arXiv
In this article we obtain a nonlocal version of the Alexandrov Theorem which asserts that the only set with sufficiently smooth boundary and of constant nonlocal mean curvature is an Euclidean ball. We consider a general nonlocal mean curvature given by a radial and monotone kernel and we formulate an easy-to-check condition which is necessary and ...

Helmholtz-Hodge decompositions in the nonlocal framework. Well-posedness analysis and applications [PDF]

arXiv, 2019
Nonlocal operators that have appeared in a variety of physical models satisfy identities and enjoy a range of properties similar to their classical counterparts. In this paper we obtain Helmholtz-Hodge type decompositions for two-point vector fields in three components that have zero nonlocal curls, zero nonlocal divergence, and a third component which

A Nonlocal Biharmonic Model with $Γ$-Convergence to Local Model [PDF]

arXiv
Nonlocal models and their associated theories have been extensively investigated in recent years. Among these, nonlocal versions of the classical Laplace operator have attracted the most attention, while higher-order nonlocal operators have been studied far less.
