Probing phase transitions of regular black holes in anti-de Sitter space with Lyapunov exponent
European Physical Journal C: Particles and FieldsWe investigate the relationship between thermodynamic phase transitions and the Lyapunov exponent of charged regular anti-de Sitter black holes in quasi-topological gravity. Our results show that the Lyapunov exponent displays multivalued behavior during

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 ...

dynoGP: Deep Gaussian Processes for Dynamic System Identification
International Journal of Adaptive Control and Signal Processing, EarlyView.This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

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.

Lyapunov exponent and charged Myers–Perry spacetimes [PDF]
, 2013 We compute the proper time Lyapunov exponent for the charged Myers–Perry black hole spacetime and investigate the instability of the equatorial circular geodesics (both time-like and null) via this exponent. We also show that for more than four spacetime
