The turnstile mechanism across the Kuroshio current: analysis of dynamics in altimeter velocity fields
Kuroshio current altimeter velocity fields dynamics
2010/4/2
In this article we explore the ability of dynamical systems tools to describe transport in oceanic flows characterized by data sets measured from satellite. In particular we have studied the geometric...
Order flow dynamics around extreme price changes on an emerging stock market
Order flow dynamics price changes emerging stock market
2010/4/27
We study the dynamics of order flows around large intraday price changes using ultra-high-frequency data from the Shenzhen Stock Exchange. We find a significant reversal of price for both intraday pri...
Opinion dynamics with confidence threshold: an alternative to the Axelrod model
stochastic processes Opinion dynamics homophily
2010/4/6
The voter model and the Axelrod model are two of the main stochastic processes that describe the spread of opinions on networks. The former includes social influence, the tendency of individuals to be...
Large-volatility dynamics in financial markets
Large-volatility dynamics financial markets
2010/4/27
We investigate the large-volatility dynamics in financial markets, based on the minutely and daily data of the Chinese Indices and German DAX. The dynamic relaxation both before and after large volati...
Cross-Correlation Dynamics in Financial Time Series
Correlation Matrix Eigenspectrum Analysis Econophysics
2010/4/27
The dynamics of the equal-time cross-correlation matrix of multivariate financial time series is explored by examination of the eigenvalue spectrum over sliding time windows. Empirical results for the...
Interaction and chaotic dynamics of the classical hydrogen atom in an electromagnetic field
classical hydrogen atom electromagnetic field angular momentum
2010/4/1
Expressions for energy and angular momentum changes of the hydrogen atom due to interaction with the electromagnetic field during the period of the electron motion in the Coulomb field are derived. It...
Multiscaled Cross-Correlation Dynamics in Financial Time-Series
Cross-Correlation Dynamics Financial Time-Series
2010/4/27
The cross correlation matrix between equities comprises multiple interactions between traders with varying strategies and time horizons. In this paper, we use the Maximum Overlap Discrete Wavelet Tran...
This paper investigates a family of dynamical systems arising from an evolutionary re-interpretation of certain optimal control and optimization problems. We focus particularly on the application in i...
Stochastic Nonlinear Dynamics of Interpersonal and Romantic Relationships
dyadic relational stochastic resonance sustained oscillation mathematical sociology social psychology
2010/4/8
Current theories from biosocial (e.g.: the role of neurotransmitters in behavioral features), ecological (e.g.: cultural, political, and institutional conditions), and interpersonal (e.g.: attachment)...
Anticipation and the Non-linear Dynamics of Meaning-Processing in Social Systems
anticipation social system meaning incursion globalization
2010/4/7
Social order does not exist as a stable phenomenon, but can be considered as "an order of reproduced expectations." When anticipations operate upon one another, they can generate a non-linear dynamics...
The Communication of Meaning in Anticipatory Systems: A Simulation Study of the Dynamics of Intentionality in Social Interactions
anticipation social system meaning communication incursion double contingency
2010/4/7
Psychological and social systems provide us with a natural domain for the study of anticipations because these systems are based on and operate in terms of intentionality. Psychological systems can be...
Measure-Differential Inclusions in Percussional Dynamics
Particle dynamics normal percussions bounded variation measure-differential inclusions
2009/2/5
We give an existence result for the dynamics of a system of particles moving on a line in a horizontal plane and subjected to friction, to percussional effects, to stiffness and to damping. The novelt...
Stabilizing the chaotic dynamics of the LÄu system
controlling chaos linear feedback control
2009/1/7
The chaotic dynamics of the LÄu system introduced in [5] is
stabilized. First, we suppress the chaos stabilizing the dynamics of the
system to the unstable equilibria. Then, using a simple line...
