MRI-acquired volumetric measurements from 100 dogs with presumptive idiopathic epilepsy (IE) and 41 non-epileptic (non-IE) dogs were used to determine if hippocampal asymmetry exists in the IE as compared to the non-IE dogs. MRI databases from three institutions were searched for dogs that underwent MRI of the brain and were determined to have IE and those that were considered non-IE dogs. Volu...

EEcient iterative methods for the numerical solution of three-dimensional acoustic scattering problems are considered. The underlying exterior boundary value problem is approximated by truncating the unbounded domain and by imposing a non-reeecting boundary condition on the artiicial boundary. The nite element discretization of the approximate boundary value problem is performed using locally t...

Particle-based simulation represents a powerful approach to modeling physical systems in electronics, molecular biology, and chemical physics. Accounting for the interactions occurring among charged particles requires an accurate and efficient solution of Poisson's equation. For a system of discrete charges with inhomogeneous dielectrics, i.e., a system with discontinuities in the permittivity,...

This paper contrasts the performances of three iterative solvers for large sparse linear systems arising in the numerical computations of incompressible Navier-Stokes equations. The emphasis is on the traditional GaussSeidel (GS) and Point Successive Over-relaxation (PSOR) algorithms as well as Krylov projection techniques such as Generalized Minimal Residual (GMRES). The performances of these ...

Economic models are used for many purposes, including forecasting and simulation. Economic models are generally nonlinear. Even simple macroeconomic models, where all the stochastic equations in the system may be linear in logarithms, need to be completed by accounting identities that are linear in levels. As a consequence, although a model may be estimated using linear techniques, forecasts wi...
