During cardiac arrhythmia, the heart frequency is an important physiological parameter that can be identified by analyzing electrocardiogram (ECG) signals. However, the accuracy of the frequency ...

First-order derivatives: n additional function calls are needed. Second-order derivatives based on gradient calls, when the "grd" module is specified (Dennis and Schnabel 1983): n additional gradient ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last ...

Ultrafast lasers are lasers that produce short pulses of light, typically less than one picosecond. These devices often rely on techniques such as mode locking to create a train of pulses. Ultrafast ...

In this paper, we propose FrSAM, a channel structure-aware merging method in the fractional Fourier domain (FrFD) for single-input multiple-output (SIMO) underwater acoustic communication systems.

Prismo implements the Finite-Difference Time-Domain method for solving Maxwell's equations, with features designed for photonic integrated circuits, waveguides, and optical devices.
