Abstract: In this paper, we present a novel convolution theorem which encompasses the well known convolution theorem in (graph) signal processing as well as the one related to time-varying filters.

Update: A minibus spending package passed by the House of Representatives on January 8, 2026, effectively cancels the Mars Sample Return program by eliminating almost all funding for future missions.

The amount of noise The Row’s annual sample sale generated last weekend was perhaps antithetical to the brand’s ultimate quiet luxury status. But what else could be expected? The brand’s legions of ...

Android has long been focused on running mobile apps, but in recent years, features aimed at developers and power users have begun pushing its boundaries. One exciting frontier: running full Linux ...

TL;DR: Minecraft's next-generation update introduces Vibrant Visuals, a major graphical overhaul featuring directional and volumetric lighting, realistic shadows, reflections, and subsurface ...

On Thursday, pioneering computer engineer and Apple veteran William “Bill” Atkinson died of pancreatic cancer at his home in Portola Valley, California, surrounded by family. He was 74. “We regret to ...

Abstract: We propose reparameterized refocusing convolution (RefConv) as a replacement for regular convolutional layers, which is a plug-and-play module to improve the performance without any ...

A windowed sinc function can implement a low-pass filter, and a two-dimensional convolutional filter can blur or sharpen images. In part 3 of this series, we introduced a low-pass filter based on the ...

Convolution is used in a variety of signal-processing applications, including time-domain-waveform filtering. In a recent series on the inverse fast Fourier transform (FFT), we concluded with a ...

Freshly revealed at Minecraft Live, a major new graphical update is on the way to Minecraft, titled "Vibrant Visuals." This upcoming upgrade will initially be released for compatible Minecraft: ...
