IET Power Electronics, EarlyView.Some of the topologies with a fewer number of power switches are reviewed and scrutinized. An extensive analysis of the topologies, control strategy and applications are presented here, suggesting suitable multilevel inverter solutions to the known industrial application or new research.

Parallel Simulations in Turbulent MHD
Physica Scripta, 2005 The large-scale dynamics of plasma flows can often be described within a fluidistic approximation known as onefluid magnetohydrodynamics. Complex flows such as those corresponding to turbulent regimes are ubiquitous in laboratory plasmas and in astrophysics, because of their typically very large Reynolds numbers.

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.ABSTRACT Background Risk factors for the placental disorders of pregnancy (pre‐eclampsia, fetal growth restriction, preterm birth, and stillbirth) are complex, frequently involving the interplay between clinical factors and wider social and environmental determinants of health.

Instrumental variables in the cost of illness featuring type 2 diabetes
Health Services Research, EarlyView.Abstract Objective To ascertain how an instrumental variables (IV) model can improve upon the estimates obtained from traditional cost‐of‐illness (COI) models that treat health conditions as predetermined. Study Setting and Design A simulation study based on observational data compares the coefficients and average marginal effects from an IV model to a

The mathematical theory of reduced MHD models for fusion plasmas [PDF]
arXiv, 2015 The derivation of reduced MHD models for fusion plasma is here formulated as a special instance of the general theory of singular limit of hyperbolic system of PDEs with large operator. This formulation allows to use the general results of this theory and to prove rigorously that reduced MHD models are valid approximations of the full MHD equations. In

MHD Simulation of Prominence Eruption [PDF]
The Astrophysical Journal, 2018 Abstract We carry out magnetohydrodynamic (MHD) simulations of the quasi-static evolution and eruption of a twisted coronal flux rope under a coronal streamer built up by an imposed flux emergence at the lower boundary. The MHD model incorporates simple empirical coronal heating, optically thin radiative cooling, and field-aligned ...

Therapeutic Apheresis and Dialysis, EarlyView.Abstract Objective To compare the dialysis efficiency parameters between new single‐needle dialysis and conventional double‐needle dialysis and to explore the optimal prescription parameters for single‐needle hemodialysis. Methods This study involved a prospective, cross‐over design. Eight patients were randomly divided into two cohorts, which received

Aging Cell, EarlyView.In this study, we describe a novel multi‐omics framework to train saliva‐based DNA methylation (DNAm) biomarkers that are reproducible and biologically interpretable. By leveraging a reliability dataset with replicates across tissues, we demonstrate knowledge transfer from blood DNAm to saliva DNAm data using DNAm proxies of blood proteins (EpiScores).
