Refractory Status Epilepticus Treated With Bilateral Pulvinar Deep Brain Stimulation—A Case Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT New‐onset refractory status epilepticus (NORSE) arises without an identifiable cause or prior epilepsy history, with a 16%–27% mortality rate and significant long‐term neurological sequelae. Neuromodulation such as deep brain stimulation (DBS) targeting the anterior and centromedian thalamic nuclei has shown promise when the traditional ...

A novel high-conversion-ratio bidirectional three-phase DC–DC converter

open access: yesThe Journal of Engineering, 2019
A novel high-conversion-ratio bidirectional three-phase DC–DC converter is proposed in this paper, which features not only low switch voltage and current stresses, but also automatic voltage balancing and current sharing ability without adding extra ...

Control method for improvement of power quality in single interlinking converter hybrid AC‐DC microgrids

open access: yesIET Smart Grid, 2021
Hybrid AC‐DC microgrids (HMGs) are formed by interconnecting AC microgrids (MGs) and DC microgrids via AC‐DC interlinking converters (ICs). In the islanded mode, apart from power sharing in a single MG, power sharing expansion throughout HMG is desirable.

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.

Capacitor voltage balancing control with reducing the average switching frequency in MMC

open access: yesThe Journal of Engineering, 2019
Modular multilevel converter (MMC) has a very good application prospect in the flexible high-voltage direct current (HVDC) transmission, but higher self-loss will affect the efficiency and restrict the development.

Effect of spin rotation coupling on spin transport

open access: yes, 2013
We have studied the spin rotation coupling(SRC) as an ingredient to explain different spin related issues. This special kind of coupling can play the role of a Dresselhaus like coupling in certain conditions.

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Loop stability analysis of boost circuit under globally dynamic compensation strategy

open access: yesThe Journal of Engineering, 2018
The PFC Boost converter controlled by the mode of CCM has strong non-linearity due to the use of non-linear elements such as power switch and multipliers.
