Symmetry and rigidity results for composite membranes and plates

open access: yesBruno Pini Mathematical Analysis Seminar, 2020
The composite membrane problem is an eigenvalue optimization problem deeply studied from the beginning of the '00's. In this note we survey most of the results proved by several authors over the last twenty years, up to the recent paper [14] written in ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Picone's identity and the moving plane procedure

open access: yesElectronic Journal of Differential Equations, 1995
Summary: Positive solutions of a class of nonlinear elliptic partial differential equations are shown to be symmetric by means of the moving plane argument coupled with spectral theory results and Picone's identity. The method adapts easily to situations where the moving plane procedure gives rise to variational problems with positive eigenfunctions.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Dynamic response of a multilayered half-plane under moving loads with analytical layer-element method

open access: yesYantu gongcheng xuebao, 2018
The analytical layer-element method owns higher computation efficiency and numerical stability. Hence, this method is utilized to analyze the dynamic response of an isotropic multilayered half-plane subjected to a moving load.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

A Liouville Type Result for Schrödinger Equation on Half-Spaces

open access: yesAbstract and Applied Analysis, 2013
We consider a nonlinear Schrödinger equation with a singular potential on half spaces. Using a Hardy-type inequality and the moving plane method, we obtain a Liouville type result for its nonnegative solutions.
