On the Convergence Rate of the Caputo Fractional Difference Logistic Map of Nilpotent Matrices

Fractal and Fractional
The convergence rate of the Caputo fractional difference logistic map of nilpotent matrices is investigated in this paper. The divergence rate of the auxiliary parameters governing the dynamics of nilpotents is exponential and is multiple to the Lyapunov

Quantization of Nonlinear Systems

Journal of Mathematical Physics, 1960
A direct method of quantization, applicable to a given nonlinear hyperbolic partial differential equation, is indicated. From such classical equations alone, without a given Lagrangian or Hamiltonian, or a priori linear reference system such as a bare or incoming field, a quantized field is constructed, satisfying the conventional commutation relations.

Structure of hexapod 3D packings: understanding the global stability from the local organization

EPJ Web of Conferences, 2017
Aggregates of non-convex particles have shown to be particularly stable which makes them good candidates to design new lightweight and reversible structures. However, few is known about the fundamental reason of their stability. In this paper we presents

ECG Heartbeat Classification Using Echo State Networks with Noisy Reservoirs and Variable Activation Function

Computation
In this work, we use an Echo State Network (ESN) model, which is essentially a recurrent neural network (RNN) operating according to the reservoir computing (RC) paradigm, to classify individual ECG heartbeats using the MIT-BIH arrhythmia database.

Nonlinear systems in medicine.

The Yale journal of biology and medicine, 2004
Many achievements in medicine have come from applying linear theory to problems. Most current methods of data analysis use linear models, which are based on proportionality between two variables and/or relationships described by linear differential equations.
