DC Solid-State Circuit Breakers with Two-Winding Coupled Inductor for DC Microgrid
Ensuring a protection scheme in a DC distribution system is more difficult to achieve against pole-to-ground faults than in AC distribution system because of the absence of zero crossing points and low line impedance.

The employment effects of working time reductions: Sector‐level evidence from European reforms
Abstract In this paper, we exploit a panel of industry‐level data in European countries to study the economic impact of national reductions in usual weekly working hours between 1995 and 2007. Our identification strategy relies on the five national reforms that took place over this period and on initial differences across sectors in the share of ...

A review on insulation challenges towards electrification of aircraft
Abstract Compared to the traditional aircraft, electrification of power system in aircraft has potential to revolutionise the aviation industry. Typically, more‐electric aircraft (MEA), even all‐electric aircraft has been developed and delivered to decrease the greenhouse gas emission and increase the energy efficiency.

Background Daily skin‐to‐skin contact (SSC) during early infancy fosters the long‐term development of children born preterm. This is the first randomized controlled trial assessing the potential beneficial effects of daily SSC on executive functioning and socio‐emotional behavior of children born full‐term.
