Journal ArticleDOI
Joint estimation of multiple graphical models
TL;DR: An estimator forGaussian graphical models appropriate for data from several graphical models that share the same variables and some of the dependence structure is developed, aiming to preserve the common structure, while allowing for differences between the categories.
Journal Article
Gene expression in ovarian cancer reflects both morphology and biological behavior, distinguishing clear cell from other poor-prognosis ovarian carcinomas.

TL;DR: The data indicate that gene expression patterns in ovarian adenocarcinomas reflect both morphological features and biological behavior, and provide a foundation for the development of new type-specific diagnostic strategies and treatments for ovarian cancer.
Journal ArticleDOI
Regularized estimation in sparse high-dimensional time series models
Sumanta Basu,George Michailidis +1 more
TL;DR: In this article, a measure of stability for stable Gaussian processes using their spectral properties is introduced, which provides insight into the effect of dependence on the accuracy of the regularized estimates.
Journal ArticleDOI
Sequential Experiment Design for Contour Estimation From Complex Computer Codes
TL;DR: A sequential methodology for estimating a contour from a complex computer code using a stochastic process model as a surrogate for the computer simulator is developed and applied to exploration of a contours for a network queuing system.
Journal ArticleDOI
Differential protein expression profiling by iTRAQ-2DLC-MS/MS of lung cancer cells undergoing epithelial-mesenchymal transition reveals a migratory/invasive phenotype.

TL;DR: It is shown that TGF-beta induced-EMT in human lung cancer cells (A549; adenocarcinoma cells) mediates tumor cell migration and invasion phenotypes, suggesting the acquisition of a invasive phenotype.
