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 ...

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 ...

A moving-average filter can address white noise in the time domain but performs poorly in the frequency domain. Figure 1. The convolution engine calculates y(tn) for n=6 (a) and then goes on to ...

The U.S. Office of Personnel Management (OPM) recently emailed over 2 million federal employees an offer to pay eight months of salary in exchange for resignation. Initiated by the newly launched ...

Zero-sum thinking has spread like a mind virus, from geopolitics to pop culture. Credit...Photo illustration by Pablo Delcan Supported by By Damien Cave Damien covers global affairs. He is based in ...

Chess, a zero-sum game, here seen played at a strategy session at Camp David in 1978 between the Israeli prime minister and the US National Security Advisor. The concept of zero-sum thinking ...

We report a fast and easy method (PACMAN) to assign partial atomic charges on metal–organic framework (MOF) and covalent–organic framework (COF) crystal structures based on graph convolution networks ...

Abstract: Convolution integral and convolution summation play an important role in the analysis of the linear time invariant systems. At present, many text books have published in my home country or ...
