Identification of gene pathways implicated in Alzheimer's disease using longitudinal imaging phenotypes with sparse regression. [PDF]
We present a new method for the detection of gene pathways associated with a multivariate quantitative trait, and use it to identify causal pathways associated with an imaging endophenotype characteristic of longitudinal structural change in the brains ...

A Numerically Stable Reduced-gradient Type Algorithm For Solving Large-scale Linearly Constrained Minimization Problems [PDF]
In this paper we present a reduced-gradient type algorithm for solving large-scale linearly constrained minimization problems. During each iteration of the algorithm linear systems are solved using a preconditioned conjugate-gradient scheme.

Adapted Nested Force-Gradient Integrators: The Schwinger Model Case [PDF]
We study a novel class of numerical integrators, the adapted nested force-gradient schemes, used within the molecular dynamics step of the Hybrid Monte Carlo (HMC) algorithm.

Flows of singular vector fields and applications to fluid and kinetic equations [PDF]
Several physical phenomena arising in fluid dynamics and kinetic equations can be modeled by nonlinear transport PDE. Such quantities are the vorticity of a fluid, or the density of a collection of particles advected by a velocity field which is highly ...
