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 ...

First, thank you for making such a flexible and robust code! I have been following this library for years now, and it has grown so much since then. I am currently trying to predict 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 ...

Abstract: The problem of signal estimation for sparsely and irregularly sampled signals is dealt with using continuous normalized convolution. Image values on real-valued positions are estimated using ...

Biden administration officials on Monday announced plans to expand the use of the new “continuous vetting” process for reviewing existing federal workers’ background checks to all “public trust” ...
