Abstract: This paper proposes two modulation schemes for Dual Active Bridge (DAB) converters, with the aim of maximizing Zero Voltage Switching (ZVS) operation over a wide operational range. The first ...

Human biology evolved for a world of movement, nature, and short bursts of stress—not the constant pressure of modern life. Industrial environments overstimulate our stress systems and erode both ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Scott Glaberman previously worked at the US EPA. North Carolina State University receives funding from the California Air Resources Board for a research project for which Dr. Frey is a co-principal ...

The bee, says Dr. Max Renner of the University of Munich, has a built-in time sense that ticks away, independent of all “environmental factors.” To prove his point, Dr. Renner completed this week the ...

This is a proposal to add a new kind of constant expressions: With this definition, evaluation of e.v is guaranteed to be an invocation of the implicitly induced getter named v. This does not involve ...

One of the most exciting and pressing issues in cosmology today is the discrepancy between some measurements of the local Hubble constant and other values of the expansion rate inferred from the ...

As given by Britain’s brilliant, opinionated Sir Arthur Stanley Eddington, the seven fundamental constants of Nature are: e, the charge of an electron; m, the mass of an electron (at rest); M, the ...

In one research study, participants were given a choice: Either they could pay $38 to guarantee they would get a $50 gift certificate, or they could pay $28 to enter a lottery for a chance to win ...

We have known for almost a century that the universe is expanding, but it's been surprisingly hard to nail down the rate of expansion. The availability of the James Webb Space Telescope is finally ...

Exposure to light is key in adjusting drivers' body clocks to new time zones. The Las Vegas Grand Prix is "the nastiest one of the season," one performance coach said. This article is part of "Behind ...
