Racial discrimination has been linked to allostatic load (i.e., cumulative biological stress) among African American women. However, limited attention has been given to psychosocial processes involved in the stress response—critical for understanding biological pathways to health—in studies examining racial discrimination as a social determinant of health. We examined whether the superwoman schema...
This paper presents a novel structure of high step-up DC/DC converters intended for distributed generation systems such as fuel cells and photovoltaic (PV) systems. Proposed topologies integrate the classical Y-source impedance network with different step-up cells to acquire strong boost ability which is unmatched by existing impedance networks. Compared to Y-source, proposed converters reserve versatile...
In this paper, a high performance boost converter consisting of an integrated dual-boost converter and a voltage doubler is proposed. The converter possesses quadric voltage gain through single switch and the voltage doubler further increases the voltage gain as the turn ratio rises. The voltage stresses on the switch and diodes are decreased for such cascaded topology. Mathematical analysis of the...
