PLACENTAL PATHOLOGY OF COVID-19 WITH AND WITHOUT FETAL AND NEONATAL INFECTION: TROPHOBLAST NECROSIS AND CHRONIC HISTIOCYTIC INTERVILLOSITIS AS RISK FACTORS FOR TRANSPLACENTAL TRANSMISSION OF SARS-COV-2

Placental Pathology of COVID-19 with and without Fetal and Neonatal Infection: Trophoblast Necrosis and Chronic Histiocytic Intervillositis as Risk Factors for Transplacental Transmission of SARS-CoV-2

The mechanism(s) by which neonates testing positive for coronavirus disease 2019 (COVID-19) acquire their infection has been largely unknown.Transmission of the etiological agent, SARS-CoV-2, from mother to infant has been suspected but has been difficult to confirm.This communication summarizes the spectrum of pathology findings from pregnant wome

Study on screening current field of quasi-isotropic strand and directly stacked strand at different field orientations

REBCO tapes, the so-called second-generation high temperature superconductor, have wide application prospects in electrical engineering and high field magnets because of their high critical current density and superior mechanical and electromagnetic properties.However, a screening current field (SCF) can be induced by the perpendicular component of
