AIMS The impact of CrossFit (high energy and intensity exercise) on SUI has not been well described. This study evaluates the incidence of SUI in physically active women, and examines specific exercises that can increase SUI. METHODS A cross-sectiona

The non-adiabatic wave packet collisions of B( 2 P 1/2 ) + H 2 ( j = 0) ↔ B( 2 P 3/2 ) + H 2 ( j = 0) were calculated using the time dependent Channel Packet Method to compute transition probabilities, cross sections and rate constants. While the H

The Naval Research Laboratory tight-binding (TB) method accurately describes the electronic and mechanical properties of many elemental systems, including semiconductors, simple metals, and transition metals. We report an extension of the method to a

I develop an ab initio local-orbital method for transition metals and semiconductors. The method of calculation is based on the non-self-consistent Harris functional version of the local-density approximation. In particular, I use a generalization of

We apply our tight-binding (TB) methodology to the $\mathrm{sp}$ metals Al, Ga, and In, all of which have distinctive ground states. The results show that this approach works as well for such elements as it does for transition metals. Bulk properties

We present results of a density functional theory study of the structure and energetics of small Pt clusters. The method of calculation is based on the non-selfconsistent Harris functional version of LDA (as formulated by Sankey and Niklewski, and ge

Ab initio calculations of the optical properties of silicon clusters of 20, 60, and 70 atoms are presented. Quantum molecular dynamics using a minimal sp 3 basis set are performed to find metastable and equilibrium atomic configurations. The optical

Nanoparticles are known to melt at temperatures well below the bulk melting point. This behavior is being exploited for the recrystallization of Germanium to form large-grain semiconductor thin films on flexible and low temperature substrates. The me

We describe our progress in developing an ab initio computational scheme for the calculation of the dielectric response function of solids, with special emphasis here on Si and C clusters. All calculations are carried out employing a basis of localiz
