The stochastic minimum-variance pseudo-unbiased reduced-rank estimator
(stochastic MV-PURE estimator) has been developed to provide linear estimation
with robustness against high noise levels, imperfections in model knowledge,
and ill-condi...

The current flow of high accuracy astrophysical data, among which are the
Cosmic Microwave Background (CMB) measurements by the Planck satellite, offers
an unprecedented opportunity to constrain the inflationary theory. This is
however a ch...

We show that the mapping class group of a closed surface admits a cocompact
classifying space for proper actions of dimension equal to its virtual
cohomological dimension....

This paper considers the prescribed zero scalar curvature and mean curvature
problem on the n-dimensional Euclidean ball for n≥3. Given a
rotationally symmetric function H:∂Bn→R, in this work,
we will prove th...

A model of computer system security operation is developed based on the
fork-join queueing network formalism. We introduce a security operation
performance measure, and show how it may be used to performance evaluation of
actual systems....
Koszul complexes and spectra of projective hypersurfaces with isolated

For a projective hypersurface Z with isolated singularities, we generalize
some well-known assertions in the nonsingular case due to Griffiths, Scherk,
Steenbrink, Varchenko, and others about the relations between the Steenbrink
spectrum,...
