[1] An effective and widely used method for removing spurious pits in digital elevation models consists of filling them until they overflow. However, this method sometimes creates large flat regions which in turn pose a problem for the determination of accurate flow directions. In this study, we propose to suppress each pit by creating a descending path(More)
AIMS To investigate the effects of cardiac resynchronization therapy (CRT) on survival in heart failure (HF) patients with permanent atrial fibrillation (AF) and the role of atrio-ventricular junction (AVJ) ablation in these patients. METHODS AND RESULTS Data from 1285 consecutive patients implanted with CRT devices are presented: 1042 patients were in(More)
Diatoms are generally known for superior mechanical properties of their mineralised shells. Nevertheless, many copepod crustaceans are able to crush such shells using their mandibles. This ability very likely requires feeding tools with specific material compositions and properties. For mandibles of several copepod species silica-containing parts called(More)
AIMS Studies have shown that remote magnetic navigation is safe and effective for ablation of atrial arrhythmias, although optimal outcomes often require frequent manual manipulation of a circular mapping catheter. The Vdrive robotic system ('Vdrive') was designed for remote navigation of circular mapping catheters to enable a fully remote procedure. This(More)
Drought is a normal, recurring feature of climate. The characteristics of this hazard, along with its far-reaching impacts, make its effects on society, economy, and environment difficult to identify and quantify. A national drought watch system has been recommended as a necessary component of drought assessment and management. The National Drought(More)
OBJECTIVE This study aimed to investigate whether adequate treatment of Cheyne-Stokes respiration (CSR) reduces the risk of arrhythmic events in patients with chronic heart failure (CHF). METHODS A cohort of 403 registry patients with CHF (LVEF≤45%, NYHA-class≥2) and implanted cardioverter-defibrillator devices (ICD) was studied. They underwent overnight(More)
So beware, those of you to attempt to write philosophy for anyone else to read! (Reimer 2003, x) Despite attempts to establish some sort of international community of music educators who work in the field of philosophy and/or theory of music education, there remains little exchange or discussion between the Anglo-American and the European philosophy of(More)
Over the years the MOGADOC database, which covers the literature for gas-phase electron diffraction, microwave spectroscopy, and molecular radio astronomy from the inception of each method, has been developed. Recently visualization and substructure retrieval tools have been implemented. New features are described by means of typical database applications.
