This is a Python 3 package to calculate the constant angular matrix elements of spherical tensor operators of lanthanide ions in exact arithmetic using SymPy. Each matrix element is stored as signed ...

Spherical approximation techniques form a cornerstone of modern numerical integration on curved domains. These methods seek to approximate integrals over the unit sphere or related manifolds by ...

Giro arguably were the first to debut the aero road helmet genre back in 2012 with their Air Attack lid, a product that helped redefine what performance-focused road helmets could look like and ...

This paper presents a novel approach for simulating acoustic-shell interaction, specifically focusing on seabed reflection effects. The interaction between acoustic waves and shell vibration is ...

Add a description, image, and links to the shell-integration topic page so that developers can more easily learn about it.

Abstract: We present a new numerical method to solve the Boltzmann equation based on a finite element approach in angle, that combines the advantages of the discrete ordinate method (SN) and the ...

The universe might not be as you think. Until recently, the Lambda Cold Dark Matter model seemed to have a lock on cosmology. Like earlier Big Bang models, it supposes that the universe expanded from ...

Abstract: This work presents a novel dual-lens architecture using an electrically small, nondiffractive core lens made of dense thermoplastics and a large shell lens. The electrically small core lens ...

A federal law aimed at making anonymous business dealings in the United States essentially a thing of the past will go into effect on New Year’s Day, three years after becoming law. The Corporate ...
