Asymptotic behavior in time periodic parabolic problems with unbounded coefficients [PDF]

, 2010
We study asymptotic behavior in a class of nonautonomous second order parabolic equations with time periodic unbounded coefficients in R×Rd. Our results generalize and improve asymptotic behavior results for Markov semigroups having an invariant measure.

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

Three Bounded Solutions for a Degenerate Nonlinear Dirichlet Problem

Axioms
The existence of at least three bounded weak solutions is established for a nonlinear elliptic equation with unbounded coefficients. The approach is based on variational methods and critical point theorems.

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Unbounded-time reachability analysis of hybrid systems by abstract acceleration

, 2015
Linear dynamical systems are ubiquitous in hybrid systems, both as physical models or as software control modules. Therefore we need an unbounded-time reachability analysis that can cope with industrial-scale hybrid system models with hundreds of ...

Nonautonomous Kolmogorov parabolic equations with unbounded coefficients

, 2010
We study a class of elliptic operators A with unbounded coefficients defined in I x R-d for some unbounded interval I subset of R. We prove that, for any s in I, the Cauchy problem u(s, .) = f in C-b(R-d) for the parabolic equation D_tu = Au admits a ...
