Conservative finite volume element schemes for the complex modified Korteweg–de Vries equation

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2017
The aim of this paper is to build and validate a class of energy-preserving schemes for simulating a complex modified Korteweg–de Vries equation. The method is based on a combination of a discrete variational derivative method in time and finite volume ...

Dependence of two-nucleon momentum densities on total pair momentum

open access: yes, 2008
Two-nucleon momentum distributions are calculated for the ground states of 3He and 4He as a function of the nucleons' relative and total momenta. We use variational Monte Carlo wave functions derived from a realistic Hamiltonian with two- and three ...

Fluidic Momentum Controller [PDF]

open access: yes, 1988
Large angular control moments and torques are developed by controllably circulating a relatively small mass of liquid through small diameter pipes describing a large diameter loop. The loop, by generating and storing angular momentum, can thereby provide

Short-term effects of pet acquisition and loss on well-being in an unbiased sample during the COVID-19 pandemic

open access: yesScientific Reports
Research on the impact of pet ownership on well-being has produced mixed results, often influenced by a focus on pet enthusiasts. To address this bias, we conducted a longitudinal study in Hungary using a stratified random sample based on gender, age ...

Spin-Orbital momentum decomposition and helicity exchange in a set of non-null knotted electromagnetic fields

open access: yes, 2017
We calculate analytically the spin-orbital decomposition of the angular momentum using completely non-paraxial fields that have certain degree of linkage of electric and magnetic lines.
