Abstract: Peak-to-average power ratio (PAPR) is an important issue for orthogonal frequency division multiplexing (OFDM) systems. In this letter, we derive a new piecewise nonlinear companding scheme ...

Abstract: The non-linear property of magnetics poses challenges for their loss modelling in power electronics due to lacking full physical models. As a practical approach for their loss estimation, ...

Fine-scale exogenous attention within the foveola selectively enhances contrast gain at low-to-mid spatial frequencies while increasing response gain across a broad spatial frequency range.

The result is a simple and efficient neuromorphic device that mimics a brain cell ...

Amid a surge in cyberattacks, security expert Daniel Dobrygowski shares steps every small to midsize business can take to avoid being an easy target.

Background Socioeconomic deprivation has been associated with adverse outcomes after aortic surgery, although evidence ...
