Synchronization of complex networks of identical and nonidentical chaotic systems via model-matching control.

open access: yesPLoS ONE, 2019
In this work, a synchronization scheme for networks of complex systems is presented. The proposed synchronization scheme uses a control law obtained with some definitions from graph theory and solving the Model-Matching Problem for complex networks.

Rebuilding the Ladder? Contemporary Contests Over Industrial Policy

open access: yesGlobal Policy, EarlyView.
ABSTRACT Does the greater embrace of industrial policy globally signal the emergence of a New Washington Consensus? We show that the multiplication of industrial policies, while consequential, signals neither normalisation nor consensus. Rather, industrial policy is increasingly the object of contestation over norms and practices of state ...

RBFNN-PSO Intelligent Synchronisation Method for Sprott B Chaotic Systems with External Noise and Its Application in an Image Encryption System

open access: yesEntropy
In the past two decades, research in the field of chaotic synchronization has attracted extensive attention from scholars, and at the same time, more synchronization methods, such as chaotic master–slave synchronization, projection synchronization ...

Study on Super-Twisting synchronization control of chaotic system based on U model

open access: yesJournal of Hebei University of Science and Technology, 2016
A U model based Super-Twisting synchronization control method for chaotic systems is proposed. The chaos control of chaotic systems is prescribed, then, based on the current research status of chaotic systems and some useful research results in nonlinear

ALTAA: Analysis of long‐term activity patterns in ant colonies

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Collective behaviours are a fascinating study area due to the emergent properties that can only arise in groups of interacting individuals. However, their quantitative study is often impaired by technical difficulties, creating either low‐quality and sparse data or impractical data amounts, particularly when capturing large groups over long ...

Can riots represent? A democratic theory

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Political theory has been perennially concerned with interrogating, identifying, and clarifying the political functions of riots. Yet, political theorists have mostly fallen short of explaining the relationship between riots and democracy, although this is central to the democratic theory of contestation and crucial for evaluating the ...

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Generalized Synchronization of Stochastic Discrete Chaotic System with Poisson Distribution Coefficient

open access: yesDiscrete Dynamics in Nature and Society, 2013
This paper addresses the generalized synchronization of stochastic discrete chaotic systems with Poisson distribution coefficient. Firstly, based on the orthogonal polynomial approximation theory of discrete random function in Hilbert spaces, the ...

Spanish stock returns, growth, and inflation, 1900–2020

open access: yesThe Economic History Review, EarlyView.
Abstract This paper studies equity returns in the Madrid Stock Exchange and their connections with the macroeconomy from the emergence of a stock market around 1900 to its ‘big bang’ at the turn of the twenty‐first century. Using high‐quality data from primary sources and the methodology of the modern IBEX35 (published since 1987), we constructed an ...

Chaos Control and Synchronization via Switched Output Control Strategy

open access: yesComplexity, 2017
This paper investigates the control and synchronization of a class of chaotic systems with switched output which is assumed to be switched between the first and the second state variables of chaotic system.
