The Combined Effect of Obesity and Contraceptive Use on Pulmonary Embolism in Adolescent Females Residing in the United States

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive

An Improved Three-Phase Voltage Source Converter With High-Performance Operation Under Unbalanced Conditions

open access: yesIEEE Access, 2018
The unbalance of the three-phase grid-voltages/loads can cause double-frequency power ripples in the voltage source converter (VSC) system. Such power ripples can further lead to current and/or voltage ripples on the dc link, which may create instability
