Domain decomposition preconditioning for high-frequency Helmholtz problems with absorption
In this paper we give new results on domain decomposition preconditioners for GMRES when computing piecewise-linear finite-element approximations} of the Helmholtz equation $-\Delta u - (k^2+ \ri \eps)u = f$, with absorption...

Petascale solvers for anisotropic PDEs in atmospheric modelling on GPU clusters
Memory bound applications such as solvers for large sparse systems of equations remain a challenge for GPUs. Fast solvers should be based on numerically efficient algorithms and implemented such that global memory access is...

Placing strategy discourse in context
There has been increasing interest in the discursive aspects of strategy over the last two decades. In this paper we review the existing literature, focusing on six major bodies of discursive scholarship: post‐structural...

Associations of physical activity, sedentary time, and cardiorespiratory fitness with heart rate variability in 6- to 9-year-old children
Abstract: Purpose: To study the associations of physical activity (PA), sedentary time (ST), and cardiorespiratory fitness (CRF) with heart rate variability (HRV) in children. Methods: The participants were a population sample...

Longitudinal and cross-sectional associations of adherence to 24-hour movement guidelines with cardiometabolic risk.
This study aimed to examine (1) adherence to 24 h movement guidelines over a 2 years follow-up in children aged 6-8 years and (2) association of this adherence with cardiometabolic risk factors. Physical activity and sleep were...
