INFINITELY MANY SOLUTIONS FOR A CLASS OF SUBLINEAR SCHRÖDINGER EQUATIONS

Taiwanese Journal of Mathematics, 2015
In this paper, we deal with the existence of infinitely many solutions for a class of sublinear Schrodinger equation $$ \left\{ \begin{array}{ll} -\triangle u+V(x)u=f(x, u), \ \ \ \ x\in {\mathbb{R}}^{N},\\ u\in H^{1}({\mathbb{R}}^{N}). \end{array} \right. $$ Under the assumptions that $\inf_{{\mathbb{R}}^{N}}V(x) >0$ and $f(x,

Using High‐Throughput Screening to Identify Crosslinking Peptides That Control Cell‐Mediated Matrix Degradation

Advanced Healthcare Materials, EarlyView.
Protease‐degradable hydrogels mimic dynamic cell‐matrix interactions, but controlling hydrogel degradation is a challenge. We screen libraries of peptides to identify sequences that are primarily degraded by membrane‐localized proteases. Crosslinking hydrogels with these peptides enables cell to spread and migrate while reducing matrix degradation ...

Infinitely Many Sign-Changing Solutions for Some Nonlinear Fourth-Order Beam Equations

Abstract and Applied Analysis, 2013
Several new existence theorems on positive, negative, and sign-changing solutions for the following fourth-order beam equation are obtained: u(4)=f(t,u(t)),   t∈[0,1];  u(0)=u(1)=u′′(0)=u′′(1)=0, where f∈C([0,1]×ℝ1,ℝ1).

Robust pH Sensing Using a Graphene Oxide and Covalent Organic Frameworks Composite for Gastro‐esophageal Reflux Disease Diagnosis

Advanced Healthcare Materials, EarlyView.
A stable composite pH sensor is developed by coating graphene oxide (GO) nanosheets with covalent organic frameworks (COFs) to improve stability and sensitivity in acidic environments. The GO/COFs sensor demonstrates high selectivity, linearity, and biocompatibility, offering a promising strategy for continuous pH monitoring in gastro‐esophageal reflux
