This paper suggests tools that provide significant improvements in the design and verification of FPGA-based digital circuits. These tools include reusable specifications of hardware components (modules) that have been proposed for two types of CAD environments; Xilinx ISE 5.x and Celoxica DK1. The components can be employed to implement both(More)
Electronic devices used in the scope of robotics and embedded systems have to be adapted to numerous external events and many of them might be unknown in advance. This application-specific particularity requires environment-specific adaptation and frequent changes in the pre-defined behaviour. In general, all feasible functionality cannot be incorporated in(More)
Endomyocardial biopsy is still the principal method for diagnosing cardiac allograft rejection. However, this procedure can be associated, albeit rarely, with potentially serious complications. We describe the case of a patient with extensive anterior myocardial infarction without revascularization, who developed cardiogenic shock and required heart(More)
Atrial fibrillation is the most common cardiac arrhythmia, and its prevalence is increasing. Cardioembolic stroke, most of the times secondary to thrombus formation in the left atrial appendage, is its most feared and life threatening consequence. Oral anticoagulation with vitamin-K-antagonists is currently the most used prophylaxis for stroke in patients(More)
Coronary subclavian steal syndrome is a rare ischemic cause in patients after myocardial revascularization surgery. Subclavian artery stenosis or compression proximal to the internal mammary artery graft is the underlying cause. The authors present a clinical case of a patient with previous history of non-ST elevation myocardial infarction, triple coronary(More)
BACKGROUND The revascularization strategy of the left main disease is determinant for clinical outcomes. OBJECTIVE We sought to 1) validate and compare the performance of the SYNTAX Score 1 and 2 for predicting major cardiovascular events at 4 years in patients who underwent unprotected left main angioplasty and 2) evaluate the long-term outcome according(More)
[U(Tp(Me2))2(bipy˙)], a uranium(III) complex with a radical bipyridine ligand which has magnetic properties with contributions from both the ligand and the metal, presents slow relaxation of the magnetisation at low temperatures, already under zero static magnetic field, and energy barriers slightly above the non-radical analogues.
