Direct Synthesis of High‐Valence Protein@UiO‐66 Composites: Linking Crystallization Pathways to Protein Encapsulation

open access: yesAdvanced Materials, EarlyView.
This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...

Principles of Constructing Layered Neural Networks Based on Pulse Neurons

open access: yesМоделирование и анализ информационных систем, 2011
In the article we describe principles of pulse implementation of multilayer neural networks using biologically plausible neurons. It is shown that the multilayer perceptron can be modeled with a neural network composed of pulse neurons using impulse ...

Asymptotic behaviours of stochastic differential delay equations

open access: yes, 2005
Most of the existing results on stochastic stability use a single Lyapunov function, but we shall instead use multiple Lyapunov functions in this paper.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Asymptotic expansion of stationary distribution for reflected Brownian motion in the quarter plane via analytic approach

open access: yesStochastic Systems, 2017
Brownian motion in R2+ with covariance matrix Σ and drift μ in the interior and reflection matrix R from the axes is considered. The asymptotic expansion of the stationary distribution density along all paths in R2+ is found and its main term is ...

High-frequency averaging in semi-classical Hartree-type equations [PDF]

open access: yes, 2009
We investigate the asymptotic behavior of solutions to semi-classical Schröodinger equations with nonlinearities of Hartree type. For a weakly nonlinear scaling, we show the validity of an asymptotic superposition principle for slowly modulated highly ...

Asymptotic Analysis of Symmetric Functions [PDF]

open access: yesJournal of Theoretical Probability, 2016
In this paper we consider asymptotic expansions for a class of sequences of symmetric functions of many variables. Applications to classical and free probability theory are discussed.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Time‐Resolved Simultaneous Mapping of Thickness and Nanoparticle Concentration in Nanofluid Thin Films via Imaging Ellipsometry and Deep‐UV Reflectance Imaging

open access: yesAdvanced Materials Interfaces, EarlyView.
This study establishes a dual‐channel optical metrology framework integrating phase‐shifting imaging ellipsometry and deep‐UV reflectance imaging. This label‐free approach enables simultaneous, time‐resolved mapping of film thickness and nanoparticle (NP) concentration in dynamic nanofluid thin films.

Asymptotic Analysis of Quenching Problems

open access: yesRocky Mountain Journal of Mathematics, 1992
Let \(\Omega\subset \mathbb{R}^ n\) be a bounded domain with smooth boundary and let \(\alpha>0\). Consider the problem \[ u_ t- \Delta u=- u^{- \alpha}\text{ in }(0,T)\times \Omega,\;u=1\text{ on } (0,T)\times \partial\Omega,\;u(0,x)= u_ 0(x). \] Here \(0< u_ 0(x)\leq 1\) is assumed and we assume that \(u\) quenches at time \(T< \infty\).
