The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time ...

Abstract: A complex-frequency-shifted perfectly matched layer (CFS-PML) for the face-centered cubic finite-difference time-domain (FCC-FDTD) method with second-order in time and fourth-order in space, ...

Decades of cognitive research reveal that parrots can understand what numbers represent. Here’s how these birds use them to ...

The Bjerksund-Stensland model is a key method for pricing American options. It helps investors determine optimal times for exercising options with dividends considered.

Periodic wetting and drying occur extensively in many shallow water systems such as coastal wetlands. Proper description of the wetting and drying front (WDF) is a challenge for hydrodynamic models of ...

Abstract: The article traces the evolution of numerical tools from the Renaissance to the present. It examines the flourishing of numerical methods and concepts in the nineteenth century, particularly ...

Our Methods Groups provide policy advice and focus on developing the methods used to produce Cochrane reviews. Over the past year they’ve been working hard on activities from writing papers on ...

Inspired by path integral solutions to the quantum relaxation problem, we develop a numerical method to solve classical stochastic differential equations with multiplicative noise that avoids ...

This study presents an (ε, μ)−uniform numerical method for a two-parameter singularly perturbed time-delayed parabolic problems. The proposed approach is based on a fitted operator finite difference ...
