Constrained-Transport Magnetohydrodynamics with Adaptive-Mesh-Refinement in CHARM
, 2011 We present the implementation of a three-dimensional, second order accurate Godunov-type algorithm for magneto-hydrodynamic (MHD), in the adaptive-mesh-refinement (AMR) cosmological code {\tt CHARM}.

Phantom validation of quantitative Y-90 PET/CT-based dosimetry in liver radioembolization
EJNMMI Research, 2017 BackgroundPET/CT has recently been shown to be a viable alternative to traditional post-infusion imaging methods providing good quality images of 90Y-laden microspheres after selective internal radiation therapy (SIRT).

Pairwise MRF Calibration by Perturbation of the Bethe Reference Point [PDF]
, 2012 We investigate different ways of generating approximate solutions to the pairwise Markov random field (MRF) selection problem. We focus mainly on the inverse Ising problem, but discuss also the somewhat related inverse Gaussian problem because both types

A Fast First-Order Optimization Approach to Elastoplastic Analysis of Skeletal Structures
, 2016 It is classical that, when the small deformation is assumed, the incremental analysis problem of an elastoplastic structure with a piecewise-linear yield condition and a linear strain hardening model can be formulated as a convex quadratic programming ...

The Origins of Computational Mechanics: A Brief Intellectual History and Several Clarifications [PDF]
, 2017 The principle goal of computational mechanics is to define pattern and structure so that the organization of complex systems can be detected and quantified.

A Bayesian Nonparametric Markovian Model for Nonstationary Time Series
, 2016 Stationary time series models built from parametric distributions are, in general, limited in scope due to the assumptions imposed on the residual distribution and autoregression relationship.
