We thought it would be helpful to put together a glossary with definitions of some of the most important words and phrases that we use in our articles.

Abstract: This paper is concerned with a modified version of the frequency domain physical realizability ... quantum harmonic oscillator and are governed by linear quantum stochastic differential ...

This is a 2D orthogonal elliptic mesh (grid) generator which works by solving the Winslow partial differential equations (Elliptic ... to an arbitrarily defined domain. The implemented solution uses ...

Abstract: In this paper, a novel model reduction technique for discrete linear time invariant systems ... Two modified Lyapunov equations are derived for the proposed frequency-domain balancing.

Over the intervening years, fitted meshes have been shown to be effective for an extensive set of singularly perturbed partial differential equations. In the revised version of this book, the reader ...

Boundary-domain integral equations (BDIEs) have emerged as a robust framework for the reformulation and solution of boundary value problems (BVPs) in complex settings. By incorporating integrals ...

Time-domain integral equations (TDIEs) play a central role in the numerical simulation of electromagnetic scattering phenomena. Unlike frequency-domain methods, TDIEs capture the transient ...

Southern Oscillation’s global reach and complex ocean–atmosphere interactions across timescales, two simple, elegant equations capture its key dynamics and defining properties.

A research team has developed a novel method for estimating the predictability of complex dynamical systems. Their work, ...

As quantum computing hardware advances, the demand for scalable, precise, and fully automated verification techniques for ...

Symmetry is a fundamental characteristic of most multi-cell animals. However, the cell division of embryonic cells is ...

A team of researchers from the Massachusetts Institute of Technology used Frontier to chart the isospin density of a neutron ...
