Understanding Atrial Fibrillation Complexity Through the Lens of Turbulence Dynamics: Implications for Treatment Strategies

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 2, Page 400-412, February 2026.
ABSTRACT Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. Its incidence increases significantly with age and has become a major global public health issue. Although research into the mechanisms of AF has spanned over a century‐ranging from the reentry theory to the rotor hypothesis‐none of these

Endogenous Tax Compliance and Macroeconomic Performance Driven by Satisficing Evolutionary Dynamics

Metroeconomica, Volume 77, Issue 1, Page 36-54, February 2026.
ABSTRACT We incorporate tax evasion to a demand‐led macrodynamic model of capacity utilization and output growth rate. The frequency of tax evaders is endogenously time‐varying, driven by imitation‐augmented satisficing evolutionary dynamics involving pecuniary factors, as well as non‐pecuniary elements which are reflected in the distribution of tax ...

Data‐Driven Sliding Mode Control for Partially Unknown Nonlinear Systems

International Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 629-638, 25 January 2026.
ABSTRACT This paper presents a novel data‐driven control framework for multi‐input multi‐output (MIMO) nonlinear systems with partially unknown dynamics and bounded disturbances. In practical scenarios, exact cancellation of system nonlinearities is often infeasible due to limited model information and unpredictable disturbances.

Frequency‐Domain Analysis of a Keldysh‐Like System

International Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 671-682, 25 January 2026.
ABSTRACT Complex dynamics of the system, revealing flutter and first presented by M. Keldysh, is analyzed in the paper in the frequency domain, through the describing function method. Motivated by this analysis, a system with similar behavior, but suitable for the exact frequency‐domain analysis through the locus of a perturbed relay system (LPRS ...
