Growth and oscillation of differential polynomials generated by complex differential equations

Electronic Journal of Differential Equations, 2013
The main purpose of this article is to study the controllability of solutions to the linear differential equation $$ f^{(k)}+A(z) f=0quad (kgeqslant 2) .

Regularity and convergence rates for the Lyapunov exponents of linear cocycles

Journal of Modern Dynamics, 2013
We study linear co-cycles in GL(d,R) (or C) depending on a parameter (in a Lipschitz or Holder fashion) and establish Holder regularity of the Lyapunov exponents for the shift dynamics on the base. We also obtain rates of convergence of the finite volume exponents to their infinite volume limits.

Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching

Advanced Materials, EarlyView.
By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...

Growth of solutions to linear differential equations with entire coefficients

Electronic Journal of Differential Equations, 2012
In this article, we study the growth of solutions of linear differential equations with some dominant entire coefficients. Especially, we obtain some results on the iterated p-lower order of these solutions, which extend previous results.

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Where Precursor Loading Stops Making a Difference: Resolving an Operational Infiltration Limit for Nanoparticle Synthesis Using Dual Quantification of Reverse Micelle Nanoreactors

Advanced Materials Interfaces, EarlyView.
A dual characterization strategy combining nanomechanical and mass measurements resolves a common operational loading threshold in reverse micelle nanoreactors. This transferable framework provides a rational strategy for optimizing precursor loading and nanoparticle synthesis, across template‐mediated fabrication systems.

Tracking the chaotic behaviour of fractional-order Chua’s system by Mexican hat wavelet-based artificial neural network

Journal of Low Frequency Noise, Vibration and Active Control, 2019
In this paper, a process is devised systematically to scrutinize the scrolling chaotic behaviour of fractional-order Chua's system. The process is composed of fractional Laplace transformation, artificial neural network with Mexican hat wavelet as an ...

Cellulose Surface Modification Effects on Equilibrium and Non‐Equilibrium Wetting by Water

Advanced Materials Interfaces, EarlyView.
Molecular dynamics simulations of nanometer‐sized water droplets spreading on cellulose substrates show strong effects from surface chemistry on both equilibrium contact angles and spreading dynamics. ABSTRACT Chemical modification is an important route to tuning interactions between nanocellulose and its surrounding media. Specifically, it affects the

Hurst's exponent behaviour, weak-form stock market efficiency and financial liberalization: the Tunisian case [PDF]

In this paper, we test the weak-form stock market efficiency for the Tunisian stock market (TSE). Our empirical approach is founded on the analysis of the behaviour over time of the Hurst's exponent.

Multi‐Parametric Fluorescence Spectroscopy for the Detection and Characterization of Plant‐Derived Protein Residues on 316L Stainless Steel

Advanced Materials Interfaces, EarlyView.
UV–vis fluorescence spectroscopy enables sensitive monitoring of plant protein adsorption on AISI 316L stainless steel under food‐processing‐relevant conditions. Spectral deconvolution reveals adsorption‐induced changes associated with protein–surface interactions and conformational alterations, demonstrating the potential of the technique for ...
