EEcient, large-scale estimation methods such as nested dissection or multiscale estimation rely on a divide-and-conquer strategy, in which a statistical problem is conditionally broken into smaller pieces. This conditional decorrelation is not possible for arbitrarily large problems due to issues of computational complexity and numerical stability. Given the growing interest in global-scale rem...

Application of the Minimum Description Length (MDL) principle to multiresolution image denoising has been somewhat unsuccessful to date. This disappointing performance is due to the crudeness of the underlying prior image models, which lead to overly sparse solutions. We propose a new family of complexity priors based on Rissanen's universal prior for integers , which produces estimates with be...

Blind synchronization of Minimum-Shift-Keying signals in the context of time-selective fading communication channels is considered. Strictly feedforward algorithms based on second-and fourth-order cyclic statistics are proposed for frequency and timing ooset estimation. The new esti-mators are shown to outperform existing methods. Extensions of the algorithm to GMSK are also studied. Finally, f...

A lo llargo del últimu añu, y pola mor de la pandemia coronavirus, apaecieron términos nuevos, neoloxismos construcciones léxiques que s’introduxeron nel nuestru vocabulariu diariu. Esti trabayu analiza si l’asturianu foi quien a absorber adaptar esti léxicu si, poro, puede considerase una llingua viva actualizada. Pa ello trabáyase cola terminoloxía d’un corpus formáu por testos periodísticos,...

We consider the problem of subspace estimation in aBayesian setting. Since we are operating in the Grassmann man-ifold, the usual approach which consists of minimizing the meansquare error (MSE) between the true subspace and its estimatemay not be adequate as the MSE is not the natural metric in theGrassmann manifold , i.e., the set of -dimensional subspacesin . As an al...

Currently the preferred method for implementing H esti mation algorithms is what is called the array form and includes two main families square root array algorithms which are typically more stable than conventional ones and fast array algorithms which when the system is time invariant typically o er an order of magnitude reduction in the com putational e ort Using our recent observation that H...

Three hundred commensal Escherichia coli recovered from healthy herbivorous, carnivorous, and omnivorous mammals from one zoo were characterized for their phylogenetic origin, intestinal virulence gene (VG) prevalence, and genomic diversity. The phylogenetic structure of the E. coli (groups A, B1, B2, and D) from the herbivores was homogenous, with a prevailing representation of group B1. In th...

Peritoneal dialysis (PD) catheter-related infection is still is the most troublesome problem for continuation of PD without the need to switch to hemodialysis. We have been performing subcutaneous pathway diversion (SPD) as a surgical treatment for refractory exit-site and tunnel infection (ESTI). To clarify the efficacy and safety of SPD, we conducted a retrospective study. From August 2008 to...

Brutsaert (1979, 1982) suggested a method for the complementary model taking atmospheric stability into account on the basis of the Monin-Obukhov similarity theory. Katul and Parlange (1992a, 1992b) and the authors (1993) independent ly published the papers on the estimation of latent and sensible heat fluxes including the effects of the atmospheric stabil ity. Parlange and Katul (1992c) actual...
