An unknot (also known as the trivial knot) can be drawn with any number of crossings. Any possible manipulation of a knot ...

Abstract: A novel approach is proposed to solve ultrawideband scattering problem of dielectric objects, which employs the time-domain integral equation (TDIE) method. The frequency band spans from ...

This tried-and-true method is one of the best ways to study so you actually retain information—and it's not hard to do. Here's what you need to know.

Certain appliances will pull power as long as they're plugged in, running up your electric bill in the process.

Abstract: Tropical geometry has recently found several applications in the analysis of neural networks with piecewise linear activation functions. This article presents a new look at the problem of ...
