Analytical calculation of resonant inductance for zero voltage switching in phase-shifted full-bridge converters [PDF]
, 2013 The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the ...

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

A Novel Method of Estimating Induction Motor q-axis Leakage Inductance
Kongzhi Yu Xinxi Jishu, 2010 The q-axis leakage inductance Ls is always used in the control of induction motor. The parameters generally come from the analysis and calculation of the magnetic field or magnetic path, so some errors are hard to avoid.
