Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

Advanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Controllability and feedback stabilizability in a nonuniform framework

Comptes Rendus. Mathématique
We propose a new controllability property for linear nonautonomous control systems in finite dimension: the nonuniform complete controllability, which is halfway between the classical Kalman’s properties of complete controllability and uniform complete ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

An analytical model for saturated nonuniform laminar flow through rough fractures

Estimating the flow rate accurately through a single rough fracture poses a fundamental challenge. This study presents an analytical model for single-phase saturated nonuniform laminar flow through rough fractures.

Tiny golden angles and nonuniform self-gating: MRI of nonuniform motion

, 2016
In this thesis, solutions to two previously unsolved problems in MR imaging of nonuniform motion will be proposed: First, the combination of golden angle ordering with b-SFFP sequences for real-time imaging, and second, the self-gated imaging of ...

Knowledge-based nonuniform crossover

Proceedings of the First IEEE Conference on Evolutionary Computation. IEEE World Congress on Computational Intelligence, 2002
Summary: We present a new ``knowledge-based nonuniform crossover'' operator for genetic algorithms that generalizes uniform crossover. We extend this to ``Dynamic knowledge-based nonuniform crossover'', which constantly updates the knowledge extracted thus far from the environment's feedback on previously generated chromosomes.

Nonuniform Sampling and Multiscale Computation [PDF]

Multiscale Modeling & Simulation, 2014
In homogenization theory and multiscale modeling, typical functions satisfy the scaling law $f^ε(x) = f(x,x/ε)$, where $f$ is periodic in the second variable and $ε$ is the smallest relevant wavelength, $0<ε\ll1$. Our main result is a new $L^{2}$-stability estimate for the reconstruction of such bandlimited multiscale functions $f^ε$ from periodic ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Admissibility for nonuniform exponential contractions [PDF]

, 2010
We study the relation between the notions of nonuniform exponential stability and admissibility. In particular, using appropriate adapted norms (which can be seen as Lyapunov norms), we show that if any of their associated Lp spaces, with p∈(1,∞], is ...
