Optimized intermolecular potential for nitriles based on Anisotropic United Atoms model [PDF]

open access: yes, 2008
An extension of the Anisotropic United Atoms intermolecular potential model is proposed for nitriles. The electrostatic part of the intermolecular potential is calculated using atomic charges obtained by a simple Mulliken population analysis.

Time-Dependent Perpendicular Transport of Energetic Particles in Magnetic Turbulence with Transverse Complexity

open access: yes, 2017
The motion of energetic particles in magnetic turbulence across a mean magnetic field is explored analytically. The approach presented here allows for a full time-dependent description of the transport, including compound sub-diffusion. The first time it

Stacked Search for Gravitational Waves from the 2006 SGR 1900+14 Storm [PDF]

open access: yes, 2009
We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with the 2006 March 29 SGR 1900+14 storm. A new search method is used, "stacking'' the GW data around the times of individual soft-gamma bursts in the storm ...
