Cardioimmunologic response patterns after an acute heart failure event: Design and first results of AHF‐ImmunoCS Open
Aims We have previously shown that patients who develop heart‐reactive antibodies (HRAs) de novo after a heart failure (HF) hospitalization are at increased risk of adverse outcomes, lending weight to the hypothesis that B cells may play a…

Fluid structure interaction in pulsatile flow through an elastic pipe segment Open
Fluid-structure interaction (FSI) in elastic vessels occurs in a wide range of systems in nature and technology. A difficulty in the development and validation of FSI models is the lack of quantitative measurements of vessel response to un…

Dynamics and bifurcations of critical points of vorticity, with application to vortex merging Open
The critical points of vorticity in a two-dimensional viscous flow are essential for identifying coherent structures in the vorticity field. Their bifurcations as time progresses can be associated with the creation, destruction or merging …

From fluttering to drifting in inertialess sedimentation of achiral particles Open
There has been much recent interest in the chiral motion of achiral particles that sediment in a viscous fluid in a regime where inertial effects can be neglected. This occurs in a broad range of applications such as those involving biolog…

U-shaped disks in Stokes flow: chiral sedimentation of a non-chiral particle Open
We study the sedimentation of U-shaped circular disks in the Stokes limit of vanishing inertia. We simulate the flow past such disks using a finite-element-based solution of the three-dimensional Stokes equations, accounting for the integr…

On the short-wavelength three-dimensional instability in the cylinder wake Open
We examine the mechanisms responsible for the onset of the three-dimensional mode B instability in the wake behind a circular cylinder. We show that it is possible to explicitly account for the stabilising effect of spanwise viscous diffus…

Light-scattering reconstruction of transparent shapes using neural networks Open
The accurate characterisation of the 3D deformations of slender fibres and thin sheets in flow, is a key experimental challenge in the study of particle-laden flows. We propose a high-resolution, single-camera method to visualise non-intru…

On the onset of long-wavelength three-dimensional instability in the cylinder wake Open
We study the onset of the three-dimensional mode A instability in the near wake behind a circular cylinder. We show that long-wavelength perturbations organise in a time-shifting pattern such that the in-plane velocity in each streamwise s…

Modeling Graphene–Polymer Heterostructure MEMS Membranes with the Föppl–von Kármán Equations Open
Ultra-thin graphene-based membranes have shown significant promise for high-performance nano-electro-mechanical (NEMS) devices. The key challenge in the modeling of such membranes is that they often operate in deflection regimes where the …
