Estimation of volume status is integral to heart failure (HF) management. Measurement of inferior vena cava (IVC) diameter (IVCd) by ultrasound provides a noninvasive estimate of right atrial pressures. The GE Vscan is a handheld ultrasound (HHU) dev

The capability of intense ultrashort laser pulses to initiate, control and image vibrational wavepacket dynamics in the deuterium molecular ion has been simulated with a view to inform and direct future femtosecond pump–control–probe experiments.

Gismerøy is a small island close to the city of Mandal on the south coast of Norway. The site has been selected for industrial development. An industrial estate was developed close to the sea with no particular attention to protection. The landfill

The ionization dynamics of an initially excited aligned H(2p, m = 0) atom exposed to short intense laser pulses is studied in the non-perturbative regime based on a three-dimensional numerical solution of the time-dependent Schrodinger equation on a

Few-photon-induced breakup of helium is studied using a newly developed ab initio numerical framework for solving the six-dimensional time-dependent Schroedinger equation. We present details of the method and calculate (generalized) cross sections fo

We investigate the impact of electron-electron correlation on the ionization dynamics of helium in intense, high-frequency laser fields by solving the time-dependent Schr\"odinger equation from first principles. Although we observe a decrease in the

We present a detailed analysis of the interference effects observed for ionization in collisions of fast highly charged projectiles with molecular hydrogen. We propose a nonperturbative semiclassical approach to describe the process under considerati

Simulations in quantum mechanics can easily become extremely computationally demanding, making parallel computing a necessity. In this chapter we outline a computational technique of the time-dependent Schrodinger equation (TDSE) using pseudo-spectra

A quantum-mechanical approach is employed to study the binding of two bare nuclei of equal charge in strong laser fields beyond the dipole approximation [Smirnova et al., Phys. Rev. Lett. 90, 243001 (2003)]. The role of nondipole effects in the bindi
