A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible. Sometime in the fall of 2021, Andrew ...

Enough landmines are buried underground worldwide to circle Earth twice at the equator, but the identification and removal of these explosives is costly and time-consuming. New research could help ...

Abstract: Measuring the in situ mutual impedance matrix (MIM) of a large phased array with a quasi-random element layout is a very challenging operation. A recently developed method for extracting the ...

Bigger is always better in Las Vegas. From the Vegas Sphere to the bright lights of Miracle Mile, the Vegas Strip seems to always be outdoing itself. AREA15 is doing just that with the help of ...

We audiophiles often say that our interest in gear is rooted in our love of music. That isn’t always truly the case, but in this instance, it is. My interest in the German pro-audio company Holoplot ...
