Our research proves a conjecture from string theory asserting the vanishing of a specific convolution sum arising in the 4-graviton scattering amplitude in 10-dimensional type IIB string theory. The ...

Abstract: Efficient computation of the Discrete Fourier Transform (DFT) for signals with structured frequency support remains a significant challenge in signal processing. The traditional Fast Fourier ...

The semiconductor industry continues to face numerous challenges as designs approach reticle limits, process nodes evolve and engineering resources become increasingly stretched. It is essential to ...

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 ...

Design for testability (DFT) embeds testable features into an integrated circuit (IC) during design, while silicon bring-up initiates chip evaluation and debugging. Streamlining these sequential ...

Experts at the Table: Semiconductor Engineering sat down to discuss the rapidly changing landscape of design for testability (DFT), focusing on the impact of advancements in fault models, high-speed ...

The previous generation, the Circular Ring Slim, didn’t impress us too much in our review testing process. But the company has been hard at work righting some of those wrongs. It updated the Ring Slim ...

Forbes contributors publish independent expert analyses and insights. Prakhar Khanna covers the consumer tech beat for Forbes. Buying a smart ring isn’t as seamless as purchasing a smartwatch. Ideally ...

Density functional theory (DFT) is one of the most widely used methods in the field of computational materials and has become an important research method for photocatalytic heterojunctions. Based on ...

An electromagnetic wave or signal traveling from “here” to “there” has an electrostatic field component that we call its E-field and whose direction we assign as the signal’s polarity. Often, the ...
