Inhomogeneities in 3 dimensional oscillatory media
We consider localized perturbations to spatially homogeneous oscillations in dimension 3 using the complex Ginzburg-Landau equation as a prototype. In particular, we will focus on inhomogeneities that locally change the phase of the oscillations.

Magnetic Resonance Imaging in patients with ICDs and Pacemakers [PDF]
Magnetic resonance (MR) imaging has unparalleled soft-tissue imaging capabilities. The presence of devices such as pacemakers and implantable cardioverter/defibrillators (ICDs), however, is historically considered a contraindication to MR imaging.

INTRODUCTION The first fully implantable cardiac pacemaker was inserted by Elmqvist and Senning in 19591 into an electrical engineer suffering from complete atrioventricular (AV) block. He is still alive today. Since then, and more specifically in the last decade, cardiac pacing has been transformed by technological innovation, and has resulted in ...

Post‐Translational Modifications in Animal Circadian Clocks
Circadian clocks coordinate physiology with daily environmental cycles through conserved transcriptional–translational feedback loops. This review summarizes how post‐translational modifications fine‐tune clock function, highlights the evolutionary convergence of circadian timekeeping in Drosophila and mammals, and emphasizes the central of these ...

The authors evaluated six machine‐learned interatomic potentials for simulating threshold displacement energies and tritium diffusion in LiAlO2 essential for tritium production. Trained on the same density functional theory data and benchmarked against traditional models for accuracy, stability, displacement energies, and cost, Moment Tensor Potential ...

Hacking NHS Pacemakers: A Feasibility Study [PDF]
Pacemakers are common types of implants, in recent years there have been growing concerns around the security within these devices. This paper was created with the assistance of the NHS staff at NGH, it attempts to answer the question of if it is ...

ABSTRACT Pathogenic variants in the SCN5A gene and its subunits have been identified in individuals with Brugada Syndrome. One such SCN5A variant, c.689T>C(p.Ile230Thr), was previously reported as disease‐causing only in homozygous individuals, with heterozygous carriers being unaffected.

Importance of maintained atrio-ventricular synchrony in patients with pacemarkers [PDF]
The effect of atrial contraction on cardiac function is reviewed in patients with dual chamber and rate-responsive ventricular pacemakers. The question posed was is there any haemodynamic, clinical or prognostic advantage of AV synchrony in dual chamber ...
