In this paper the quadratic risk of a homogeneous linear estimator and the ordinary least squares estimator is compared in subsets of the parameter space and conditions for strong (matrix risk) and ...

Let A be a stochastic matrix and ε a positive number. We consider all stochastic matrices within ε of A and their corresponding stochastic eigenvectors. A convex polytope containing these vectors is ...

Researchers have developed a spontaneous polymer network synthesis that allowed for the preparation of gels containing narrow molecular weight distribution polymers. The gel networks showed swelling ...
