Exponential windowing is a widely used technique for suppressing the effects of old data as new data is added to a matrix. Specifically, given an n x p matrix Xn and a "forgetting factor" ß € (0, 1 ), one works with the matrix diag(/i'1_1, ß"~2, ... , \)Xn ■ In this paper we examine an updating algorithm for computing the QR factorization of diag(/j"-1, ß"~2 , ... , \)X„ and show that it is unc...

Introduction Although several studies suggest that the prognosis of hypertensive dialysis patients can be improved by using antihypertensive drug therapy, it is unknown whether the prescription of a particular class or combination of antihypertensive drugs is beneficial during hemodialysis. Methods We performed a propensity score matching study to compare the effectiveness of various classes ...

The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases bacteria.

In the last decades new pharmacodynamic properties of beta-adrenoceptors have been discovered that could greatly impact in the use of beta-adrenergic agents in the clinical practice. Concepts such as multiple binding sites, constitutive activity, polymorphism and intracellular signaling of betaadrenoceptors may contribute in the discovery of more efficacious pharmacological agents for treatment...

The total and regional peripheral resistance and capacitance of the vascular system is regulated by the sympathetic nervous system, which influences the vasculature mainly through changes in the release of catecholamines from both the sympathetic nerve terminals and the adrenal medulla. The knowledge of the targets for noradrenaline and adrenaline, the main endogenous catecholamines mediating t...

BACKGROUND Family- and home-related factors have been shown to be associated with children's physical activity (PA), but may be time-dependent. Here we investigate whether family- and home-related correlates of children's PA are different for the after-school period on weekdays than for the weekend. METHODS Data on 21 family- and home-related variables and objectively measured PA (Actigraph G...

We report on variational calculations of the energy E(p, ß) of asymmetric nuclear matter having p = p +pp = 0.05 to 0 .35 fm-~, and ß = (P -p~)lp = 0 to l . The nuclear hamiltonian used in this work consists of a realistic two-nucleon interaction, called °i<, that fits the available nucleon-nucleon scattering data up to 425 MeV, and a phenomenological three nucleon interaction adjusted to repro...

Background The extended spectrum ß-lactamases (ESBL) are enzymes that produce resistance to ß-lactam antibiotics, including penicillins, wide spectrum cephalosporins and aztreonam, by cleavage of ß-lactam ring (BUSH & JACOBY, 2010). Since ESBL-producing bacteria are frequently associated with nosocomial infections, treatment options are becoming increasingly limited (RAWAT & NAIR, 2010). In thi...

ß We develop an application to identify and characterize polygonal features in SAR images, based on a watershed algorithm, modified for a good robustness to radar noise. ß Our system performs a multi-scale analysis of the image. Oversegmentation is prevented by a selection of outstanding contours; regions with less prominent contours are merged ß This analysis is applied to Venus images from th...
