In this paper, we review recent work on novel computing paradigms using coupled oscillatory dynamical systems. We explore systems of relaxation oscillators based on linear state transitioning devices, which switch betwee...

In this paper , a new four-dimensions hyperchaotic system is proposes based on a three-dimensional Pan system by introducing a nonlinear state feedback controller, and we investigated some basic properties for this syste...

In the present study, the transmission error (TE) behaviour of an identical involute spur gear pair dynamically coupled with an attached subsystem is investigated through numerical modelling. The surrounding mechanical s...

Nació en el contexto del proyecto europeo SICONOS (del inglés SImulation and Control of NOnsmooth Dynamical System), cuyo propósito fue desarrollar algoritmos y programas para la simulación y control por realimentaci...

Until the spread of digital recording technology, our knowledge of the history of avian vocal culture was based on onomatopoeic descriptions or notations inspired by musical notation. In the 1960s, hand-drawn annotations...

Abstract It is often argued that constitution and causation are different kinds of dependence relations. Some have argued for a distinction between constitutive explanation of causal capacities that explain what a system...

We propose a plain files cipher by means of a stream cryptosystem scheme with chaotic addition and a symmetric key. The sequence of numbers used for encryption is generated by a continuous chaotic dynamical system; in pa...

This brief addressed the control design problem for a bilinear dynamical system with two approaches. The first approach is proportional-integral passivity-based control theory (PI-PBC), and the second control approach is...

NESTE ARTIGO tenta-se estabelecer algumas interpretações teóricas para os conceitos de auto-organização e complexidade em sistemas biológicos, utilizando-se idéias originárias da Teoria da Informação e da Teori...

Maintaining B-cell tolerance – the elimination of self-reactive B-cells – is literally a life-long challenge because the B-cell receptor mutates to generate millions of new variants during each immune response in the...

This study investigates a fractional partial differential equation in the field of mathematical biology. The Bernoulli (G'⁄G)-expansion method is applied to solve this class of fractional-order nonlinear differential e...

Abstract We explore a cosmological framework in which a Gauss–Bonnet (GB) coupled scalar field, acting as dark energy, interacts with a fermionic dark matter field through a coupling obtained from the point of view of ...

We study a mechanistic mathematical model of extinction and coexistence in a generic hunter-prey ecosystem. The model represents typical scenarios of human invasion and environmental change, characteristic of the late Pl...

Mathematics and computer science play a pivotal role in modern biology. Dynamical models based on differential equations are particularly adapted to describe dynamic behaviors of many biological processes. However, tradi...

In this paper we raise the question “why is agreement so common across natural languages?”. We will argue that the challenge of grammar inference in natural and artificial languages provides key insights into the ubi...

The concept of topology is universally observed in various physical objects when the objects can be described by geometric structures. Although a representative example is the knotted geometry of wavefunctions in recipro...

Springer-Verlag Berlin Heidelberg(Review por invitación)In this chapter we discuss in a pedagogical way and from the verybeginning the "Mean Exponential Growth factor of Nearby Orbits method" (MEGNO), that has proven, i...

For p-polarized light incident on an interface between an ordinary dielectric and an epsilon-near-zero (ENZ) material, an enhancement of the component of the electric field, normal to this interface, has been shown to oc...
