A stabilized MFE reduced-order extrapolation model based on POD for the 2D unsteady conduction-convection problem

Journal of Inequalities and Applications, 2017
In this study, we devote ourselves to establishing a stabilized mixed finite element (MFE) reduced-order extrapolation (SMFEROE) model holding seldom unknowns for the two-dimensional (2D) unsteady conduction-convection problem via the proper orthogonal ...

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Modulating the Optoelectronic Properties of Tripodal Fluorophores Through Fluorine‐Substituted Peripheral Phenyls

Chemistry – A European Journal, EarlyView.
C3‐symmetric D‐(π‐D‐π‐A)3 fluorophores featuring central triphenylamine donor, polarizable 2,5‐divinylthiophene linker, and a broad portfolio of fluorine‐based substituents show tunable (non)linear optical properties. ABSTRACT Fourteen novel tripodal fluorophores based on a central triphenylamine donor, electron‐rich, and polarizable divinylthiophene ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

An optimized finite difference Crank-Nicolson iterative scheme for the 2D Sobolev equation

Advances in Difference Equations, 2017
In this paper, we devote ourselves to establishing the unconditionally stable and absolutely convergent optimized finite difference Crank-Nicolson iterative (OFDCNI) scheme containing very few degrees of freedom but holding sufficiently high accuracy for

A Modular Regularized Variational Multiscale Proper Orthogonal Decomposition for Incompressible Flows

, 2017
In this paper, we propose, analyze and test a post-processing implementation of a projection-based variational multiscale (VMS) method with proper orthogonal decomposition (POD) for the incompressible Navier-Stokes equations.
