Stochastic Galerkin Matrices
We investigate the structural, spectral, and sparsity properties of Stochastic Galerkin matrices as they arise in the discretization of linear differential equations with random co...

Discovering Cyclic Causal Models by Independent Components Analysis
We generalize Shimizu et al's (2006) ICA-based approach for discovering linear non-Gaussian acyclic (LiNGAM) Structural Equation Models (SEMs) from causally sufficient, conti...

Delay Analysis for Cognitive Radio Networks with Random Access: A Fluid Queue View
Abstract—We consider a cognitive radio network where multiple secondary users (SUs) contend for spectrum usage, using random access, over available primary user (PU) channels. Ou...

A Mathematical Analysis of an Age-sex-space-structured Population Dynamics Model with Random Mating and Females' Pregnancy
We discuss an age-sex-structured population dynamics deterministic model taking into account random mating of sexes, females’ pregnancy and its dispersal in whole space. This mod...

Assessing Statistical Reliability of LiNGAM via Multiscale Bootstrap
Structural equation models have been widely used to study causal relationships between continuous variables. Recently, a non-Gaussian method called LiNGAM was proposed to discover ...
