Probing thermodynamic phase transitions of 4D R-charged black holes via lyapunov exponent
Nuclear Physics BWe investigate the thermodynamic phase structure of four-dimensional R-charged black holes–characterized by four independent U(1) charges–through the lens of Lyapunov exponents associated with unstable circular orbits of both massless and massive ...

The Cardiodynamicsgram Based Early Detection of Myocardial Ischemia Using the Lempel-Ziv Complexity
IEEE Access, 2020 Background: Electrocardiogram (ECG) is a routine method for detecting myocardial ischemia in clinical practice, but more than half of ECGs are without specific ischemic changes.

On Gait Stability: Correlations between Lyapunov Exponent and Stride Time Variability
Current Directions in Biomedical Engineering, 2022 Lyapunov exponent is a promising parameter to ascertain the stability of the human gait. In this work, we use a time-series model based on a second-order delay-system with inertial measurement units placed on the foot and wrist.

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates
Advanced Science, EarlyView.Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

Probing the thermodynamics of charged Gauss Bonnet AdS black holes with the Lyapunov exponent
European Physical Journal C: Particles and FieldsIn this paper, we investigate the thermodynamic properties of the charged AdS Gauss–Bonnet black holes and their associations with the Lyapunov exponent. The chaotic features of the black holes and the isobaric heat capacity characterized by the Lyapunov

Moment Lyapunov exponent of delay differential equations
International Journal of Mathematics and Mathematical Sciences, 2002 The aim of this paper is to establish a connecting thread through the probabilistic concepts of pth-moment Lyapunov exponents, the integral averaging method, and Hale's reduction approach for delay dynamical systems.

COVARIANT LYAPUNOV EXPONENTS FOR THE MIXMASTER [PDF]
The Tenth Marcel Grossmann Meeting, 2006 The dynamics of the Mixmaster Universe is analized in a covariant picture via Misner--Chitre-like variables for an ADM Hamiltonian approach. The system outcomes as isomorphic to a billiard on the Lobachevsky plane and Lyapunov exponents are calculated explicitly.

Advanced Science, EarlyView.Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes.

Synchronization and chaos in spin torque oscillator with two free layers
AIP Advances, 2020 The magnetization dynamics in a spin torque oscillator (STO) consisting of two in-plane magnetized free layers is studied by solving the Landau-Lifshitz-Gilbert equation and evaluating the Lyapunov exponent numerically.

Lyapunov Exponent Enhancement in Chaotic Maps with Uniform Distribution Modulo One Transformation
Chaos Theory and Applications, 2022 Most of the chaotic maps are not suitable for chaos-based cryptosystems due to their narrow chaotic parameter range and lacking of strong unpredictability.
