This is a python version of the logarithmic FFT code FFTLog as presented in Appendix B of Hamilton (2000) and published at jila.colorado.edu/~ajsh/FFTLog. A simple ...

Snapchat announced Monday that a new Bitmoji style inspired by the classic 2D look will be an option for Snapchat+ subscribers in the coming days. The revamped style for the app’s popular avatars is ...

Researchers are exploring MXenes, 2D materials that could transform air into ammonia for cleaner fertilizers and fuels. Their atomic structures can be tuned to optimize performance, making them ...

A research team in Shanghai has built a full 2D flash memory chip directly on a silicon control die. It programs in 20 nanoseconds and runs real instruction sets, not just lab demos. The chip sits on ...

It stopped in for a bite. Fast food workers got a large-scale surprise when they spotted a massive python slithering around an In-N-Out burger joint in California. The non-venomous snake made its ...

Copilot 3D will turn your 2D images into 3D models. The tool is freely available to anyone, though you do need a Microsoft account. Microsoft suggests using an image with a single subject, even ...

Obtaining high-quality images of Limulidae in amphibious environments is a challenging task due to insufficient light and the complex optical properties of water, such as light absorption and ...

Fourier Neural Operators (FNO) are powerful tools for learning partial differential equation solution operators, but lack architecture-aware optimizations, with their Fourier layer executing FFT, ...

In a significant advancement for semiconductor technology, researchers at UC Santa Barbara have unveiled novel three-dimensional (3D) transistors utilizing two-dimensional (2D) semiconductors. Their ...

In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...
