More than 150, 000 patients undergo ablation for atrial fibrillation (AF) each year.Current guidelines recommend oral anticoagulation in all patients undergoing AF ablation. A large number of patients undergoing cardiac implantable electronic devices (CIEDs) are on long-term oral anticoagulation. These patients are at increased risk for thromboembolism with interruption of oral anticoagulation....

Circadian patterns have been shown in several acute cardiovascular events—for example, myocardial infarction and stroke—and such patterns could be related to blood pressure rhythms. We reviewed all cases of epistaxis from 1 January 1992 to 31 December 1998 in the emergency department of St Anna Hospital, the emergency hospital for the 150 000 people in the city and suburbs of Ferrara, Italy. In...

The molecular weight and hydrodynamic properties of a polypeptide isolated from the lamellar system of Antirrhinum chloroplasts were determined in sodium dodecyl sulphate solution by measurement of sedimentation velocity, diffusion and effective partial specific volume. The polypeptide fraction exhibits a molecular weight of 25000 which agrees with the apparent molecular weight found by polyacr...

Genetic correlations between production traits (average daily gain from birth till the end of the field test and ultrasonically predicted lean meat content at the end of the field test) and semen traits (semen volume, sperm concentration, motility, percentage of abnormal spermatozoa, total number of spermatozoa and number of functional spermatozoa) were estimated from a large dataset (44 500 ob...

Two crucial environmental problems in Louisiana are high rates of wetland loss and surface water pollution. Using wetlands for wastewater treatment can address both of these concerns by reducing the amount of pollutant discharge into surface water bodies while simultaneously serving to restore and replenish deteriorating marshes by enhancing productivity and accretion. Using wetlands for wastew...

Focusing of 8 keV x rays to a spot size of 150 and 90 nm full width at half maximum have been demonstrated at the firstand third-order foci, respectively, of a phase zone plate ~PZP!. The PZP has a numerical aperture of 1.5 mrad and focusing efficiency of 13% for 8 keV x rays. A flux density gain of 121 000 was obtained at the first-order focus. In this article, the fabrication of the PZP and i...

In this paper, we introduce a model of engagement dynamics in spelling learning. The model relates input behavior to learning, and explains the dynamics of engagement states. By systematically incorporating domain knowledge in the preprocessing of the extracted input behavior, the predictive power of the features is significantly increased. The model structure is the dynamic Bayesian network in...

Abstract. This dataset is a comprehensive, global compilation of published uranium–thorium (U-series) dated fossil coral records from ∼ 150 000–110 000 years ago, as well associated elevation measurements and sample metadata. In total, 1312 U-series 994 unique colonies are included in the current version dataset, all which have been normalized recalculated using same decay constant values. Of t...
