A Schwarzschild model of the Galactic bar with initial density from N-body simulations
, 2013 Using the potential from N-body simulations, we construct the Galactic bar models with the Schwarzschild method. By varying the pattern speed and the position angle of the bar, we find that the best-fitting bar model has pattern speed (p) = 40 km s(-1 ...

A Freefall-based Switching Criterion for P3T Hybrid N-body Methods in Collisional Stellar Systems
The Astrophysical JournalThe P ^3 T scheme is a hybrid method for simulating gravitational N -body systems. It combines a fast particle-tree (PT) algorithm for long-range forces with a high-accuracy particle–particle (PP; direct N -body) solver for short-range interactions ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Cosmological N-body simulations
, 1997 In this review we discuss cosmological N-body codes with a special emphasis on particle mesh codes. We present the mathematical model for each component of N-body codes. We compare alternative methods for computing each quantity by calculating errors for
