A novel dual-leg DC-DC converter for wide range DC-AC conversion

open access: yesAutomatika, 2022
This paper proposes DC–AC Dual-leg dual-stage Conversion (DDC) and DC–AC Direct single-stage conversions (DSC). Conventional energy conversion system has only two-stage conversion, so it has some drawbacks such as huge power loss, less conversion range ...

The tarantula toxin GxTx detains K+ channel gating charges in their resting conformation. [PDF]

open access: yes, 2019
Allosteric ligands modulate protein activity by altering the energy landscape of conformational space in ligand-protein complexes. Here we investigate how ligand binding to a K+ channel's voltage sensor allosterically modulates opening of its K ...

Nonequilibrium current driven by a step voltage pulse: an exact solution

open access: yes, 2006
One of the most important problems in nanoelectronic device theory is to estimate how fast or how slow a quantum device can turn on/off a current. For an arbitrary noninteracting phase-coherent device scattering region connected to the outside world by ...

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Breakdown voltage improvement of enhancement mode AlGaN/GaN HEMT by a novel step-etched GaN buffer structure

open access: yesResults in Physics, 2021
A research on breakdown voltage improvement of the enhancement mode (E-mode) AlGaN/GaN high electron mobility transistor (HEMT) has been carried out. A novel step-etched GaN buffer structure combined with a thin GaN buffer is studied by simulating.

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...

Design of High-Efficiency Isolated Bidirectional DC/DC Converter With Single-Input Multiple-Outputs

open access: yesIEEE Access, 2019
This study mainly develops a high-efficiency isolated bidirectional DC/DC converter (HEIBDC) with a single input and multiple outputs. For the requirement of multiple output voltages with only one single input source, the proposed HEIBDC can achieve the ...

Double Dual High Step-Up Power Converter with Reduced Stored Energy

open access: yesEnergies, 2023
This paper introduces a dual-switchhigh step-up DC-DC power converter. The proposed converter features a high step-up voltage gain, relatively low cumulative stored energy over its inductors, low voltage stress on the active switches, and high efficiency,

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours
