A Stable Hybridized Discontinuous Galerkin Method for Solving Some Nonlinear m$$ m $$‐Component Reaction–Diffusion Systems

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we present a stable numerical scheme for solving two‐dimensional m$$ m $$‐component reaction–diffusion systems. The proposed approach utilizes the backward Euler method for temporal discretization and the hybridized discontinuous Galerkin (HDG) method for spatial discretization.

High‐density MRI coil arrays with integrated field monitoring systems for human connectome mapping

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and test two high‐density MRI coil arrays with integrated field monitoring systems for enhanced diffusion imaging with strong diffusion‐sensitizing gradients. Methods Two multichannel head coils were constructed for first‐ and second‐generation 3T Connectome MRI scanners, incorporating 64 and 72 receive channels ...

Better off by risk adjustment? Socioeconomic disparities in care utilization in Sweden following a payment reform

open access: yesJournal of Policy Analysis and Management, EarlyView.
Abstract Reducing socioeconomic health inequalities is a key goal of most health systems. A challenge in this regard is that healthcare providers may have incentives to avoid or undertreat patients who are relatively costly to treat. Due to the socioeconomic gradient in health, individuals with low socioeconomic status (SES) are especially likely to be

Impregnation and saturation analysis of microwave‐preheated reactive resin in liquid composite molding

open access: yesPolymer Composites, EarlyView.
Analysis of the improvements of impregnating and saturating resin flows in microwave‐preheated liquid composite molding. Abstract In liquid composite molding processes, resin preheating is a strategy to reduce the viscosity, which consequently improves resin flow and reduces impregnation time. However, the provision of heat to thermoset systems must be

Low‐ and High‐Frequency Noise in LEDs

open access: yesphysica status solidi (a), EarlyView.
The results of optical noise measurements for commercially available blue light‐emitting diodes in a range from kHz to MHz are reported. The noise spectra decomposition into components according to the theoretical model is performed. The coincidence of the experimental results with 1/fγ model for the low‐frequency range is proved and a fitting is made.
