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 ...

Stability of mappings on multi-normed spaces [PDF]
, 2007 In this paper, we define multi-normed spaces, and investigate some properties of multi-bounded mappings on multi-normed spaces. Moreover, we prove a generalized Hyers–Ulam–Rassias stability theorem associated to the Cauchy additive equation for mappings ...

The Journal of Physiology, EarlyView.Abstract figure legend We proposed a computational constitutive modelling framework that leverages longitudinal acquisitions of haemodynamic waveforms at multiple arterial locations to achieve a biomechanical characterisation of their (micro)structural remodelling processes.

A microstructurally motivated framework to study autoregulation in the coronary circulation
The Journal of Physiology, EarlyView.Abstract figure legend A microstructurally motivated framework was constructed to simulate coronary autoregulation in symmetrically bifurcating trees at three myocardial depths: subepicardial (subepi), midwall and subendocardial (subendo). Wall mechanics of individual vessels are governed by a constrained‐mixture model, incorporating elastin, collagen ...

Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.ABSTRACT We performed first‐principles density functional theory calculations to methodically analyse the structural, mechanical, electronic, thermal, and optical properties of trigonal ZrSnO3 under external pressure up to 60 GPa with GGA‐PBE and HSE06 functionals.

International Journal of Robust and Nonlinear Control, Volume 36, Issue 10, Page 5619-5634, 10 July 2026.ABSTRACT In this paper, we consider the optimal control problem for an unknown continuous‐time nonlinear system, and present a framework that integrates model‐based and model‐free methods to solve it. Each approach offers distinct advantages: model‐based techniques provide offline synthesis and data efficiency, while model‐free procedures excel at ...

Journal of Microscopy, Volume 303, Issue 1, Page 37-52, July 2026.Abstract Paganin's method for image reconstruction in propagation‐based phase‐contrast X‐ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publications citing its use. The present paper discusses approaches to optimisation of the method with respect to simple image quality metrics, such as signal‐to‐noise ...
