Design and Simulation Analysis of Short Circuit Protection for Electric Ship DC Grid-connected System

open access: yesKongzhi Yu Xinxi Jishu, 2021
DC grid-connection technology is the core technology of electric ship. For a ship DC grid-connected distribution system, when short-circuit occurs in a branch of the system, the short-circuit branch needs to be cut off, and the other branches can be ...

Photomultiplier circuit including means for rapidly reducing the sensitivity thereof [PDF]

open access: yes, 1974
A simple, reliable and inexpensive control circuit is described for rapidly reducing the bias voltage across one or more of the dynode stages of a photomultiplier, to substantially decrease its sensitivity to incoming light at those times where excess ...

The Diagnostic Value of Visual Evoked Potentials in Chronic Disorders of Consciousness

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In chronic disorders of consciousness (DOCs), the distinction between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) is as crucial as it is challenging. Evoked potentials (EPs) and event‐related potentials (ERPs) are helpful, but some limitations prevent their consistent use in the ...

Durable B‐Cell Impairment While Sparing IgA B Cells After Ocrelizumab Therapy in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Ocrelizumab (OCR), a humanized anti‐CD20 monoclonal antibody, is highly efficient in relapsing–remitting multiple sclerosis (RR‐MS). We assessed early cellular B‐cell profiles in patients prior to OCR treatment, on OCR treatment, and after 15 months of therapy discontinuation.
