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 ...

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

Advanced 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.

The exponent of convergence of Poincaré series of combination groups

Tohoku Mathematical Journal, 1991
The author considers the free product of two discrete subgroups of the Möbius group of transformations \(GM(B^{n+1})\) with an amalgamated subgroup. For this general case he gives an estimate from below for the exponent of convergence in terms of the individual exponents.

Monolithic 3D‐Integrated All‐Solid Ion‐Gated Carbon Nanotube Transistors With Tunable Ionic Conductance for Multi‐Timescale Reservoir Computing

Advanced Materials, EarlyView.
A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...

Growth of solutions of linear differential equations with analytic coefficients of [p,q]-order in the unit disc

Electronic Journal of Differential Equations, 2014
In this article, we study the growth of solutions of homogeneous linear differential equation in which the coefficients are analytic functions of [p,q]-order in the unit disc. We obtain results about the (lower) [p,q]-order of the solutions, and the (

Existence and convergence of sign-changing solutions for Kirchhoff-type $p$-Laplacian problems involving critical exponent in $\mathbb{R}^N$

Electronic Journal of Qualitative Theory of Differential Equations
We investigate the existence of sign-changing solutions for Kirchhoff-type problems with $p$-Laplacian involving critical exponent: \begin{equation*} -\left(1+b \vert \nabla v \vert_p^p\right)\Delta_p v+a(x)\vert v\vert^{p-2}v=\vert v\vert^{p^*-2}v ...
