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.

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 ...

With talk of the Big Ten potentially kicking off another round of college football conference realignment, two current ACC schools could be in their sights, but the SEC may also be interested if it ...

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 ...
