Computational model of haemodynamics during atrial fibrillation
The Journal of Physiology, EarlyView.Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

Designing B1‐Selective Pulses by Frequency Modulating in a Second Rotating Frame
Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2689-2701, May 2026.ABSTRACT Purpose To create a frequency‐modulated pulse for slice selection of arbitrary, uniform flip angle even when B0 and B1 are inhomogeneous, without utilizing B0 gradients Theory and Methods An amplitude‐modulated hyperbolic secant pulse (AMHS1) was derived from Hoult's B1‐selective imaging method which utilizes one component, B1y, as a gradient ...

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Dynamic Event‐Triggered Robust Model Predictive Control for Quadrotor Trajectory Tracking
International Journal of Robust and Nonlinear Control, Volume 36, Issue 6, Page 3676-3688, April 2026.ABSTRACT This paper addresses the trajectory tracking problem for a full‐state quadrotor subject to physical model constraints and unknown external disturbances. A robust tube‐based model predictive control (MPC) approach is successfully applied to the system, which is subject to bounded disturbances and hard constraints.

Efficient Numerical Method for Solving a Quadratic Riccati Differential Equation
Abstract and Applied AnalysisThis study presents families of the fourth-order Runge–Kutta methods for solving a quadratic Riccati differential equation. From these families, the England version is more efficient than other fourth-order Runge–Kutta methods and practically well-suited
