UK researchers have developed a pioneering blood test using Fourier Transform Infrared microspectroscopy that can detect a single lung cancer cell circulating in the bloodstream. The technique ...

The steady-state heat equation for a circular plate with Dirichlet boundary conditions has been solved using a method that combines Fourier expansion and a second-order finite difference scheme. This ...

Terahertz (THz) communication has emerged as one of the key technologies for sixth-generation (6G) wireless networks. Nevertheless, the transition to higher operational frequencies poses various ...

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 ...

In this tutorial, we will show that by writing the Fourier series expansion of a periodic signal in an intuitively obvious form, it is possible to interpret Parseval’s equality energetically. In this ...

Convolution is a remarkable property of the Fourier transform, often cited in the literature as the “faltung theorem”. Convolution is a remarkable property of the Fourier transform, often cited in the ...

Another MLB season is almost here, and despite the many changes to the game this year — from new rules to a new schedule — 30 teams from six divisions will take the field on Opening Day, as they have ...
