This paper addresses the modeling of power supply voltage transients in digital systems, in order to estimate the system’s tolerance to this disturbance, in order to demonstrate EMI/EMC standard compliance. Electrical simulation is extensively used to demonstrate the possibility of exploiting the duality between time excitation and delay response, for combinational CUT (Circuit Under Test). We ...

AIMS The aim of this retrospective analysis was to investigate VDD mode survival, development of atrial tachyarrhythmias (AT), and long-term atrial sensing performance of VDD pacing systems. METHODS AND RESULTS We implanted single-lead VDD pacemakers in patients with isolated atrioventricular block and performed a retrospective analysis of 307 patients who had their devices implanted between ...

Vitamin D may influence iron metabolism and erythropoiesis, whereas iron is essential for vitamin D synthesis. We examined whether vitamin D deficiencies (VDD) are associated with reduced iron status and whether progressive iron deficiency (ID) is accompanied by inferior vitamin D status. The study included 219 healthy female (14-34 years old) athletes. VDD was defined as a 25(OH)D concentratio...

OBJECTIVES Vitamin D deficiency (VDD) is common in immigrant children with increased skin pigmentation living in higher latitudes. We assessed the pattern of and risk factors for VDD in immigrant East African children living in Melbourne (latitude 37 degrees 49' South). STUDY DESIGN A prospective survey of 232 East African children attending a clinic in Melbourne. Data were collected by quest...

Sixteen patients treated with a noninvasively programmable pacemaker were examined after a prolonged period of ventricular inhibited (VVI) and atrial synchronous ventricular inhibited (VDD) pacing. Maximal working capacity was determined by bicycle ergometry. Atrial and ventricular rates, brachial artery cuff pressure and breathing rate were determined at rest and during exercise. There was a m...

We present two techniques to reduce the power consumption in FPGAs. The first technique uses two supply voltages: timing-critical paths run on normal Vdd, while the non-critical ones save power by using a lower Vdd. Our programmable dual-Vdd architectures and Vdd assignment algorithms provide an average power saving of 61% across the MCNC benchmarks. The second technique targets applications wh...

In energy-aware design, especially for systems with uncertain power sources, asynchronous computation loads which can function under variable power supply have many potential advantages. Fully safe asynchronous loads based on delay insensitivity (DI), however, tend to suffer power and size penalties. As a compromise, delay bundling has been widely used in asynchronous computation, but tradition...

OBJECTIVE To examine the hypothesis that vitamin D deficiency (VDD) is associated with an increased prevalence of microvascular complications in young people with type 1 diabetes. RESEARCH DESIGN AND METHODS In a cross-sectional study of 517 patients, 25-hydroxyvitamin D was measured. Retinopathy was assessed by 7-field stereoscopic retinal photography, peripheral neuropathy by thermal and vi...

Vine decline disease (VDD) constitutes a menace to melons worldwide. Especially, the one caused by fungus Monosporascus cannonballus. Thus, resistant plant material must be released help growers. Hence, our goal was develop VDD. More than 600 melon accessions are expected tested for resistance in M. cannonballus infested soil Weslaco, Texas, USA, identify VDD, and other important traits. So far...

Studies from our center and other parts of India have drawn attention towards wide prevalence of vitamin D deficiency (VDD) in our country. VDD has been reported in all age groups including toddlers, school children, pregnant women and their neonates and adult males and females residing in rural and urban India. We reviewed implications of VDD in our population based on the preliminary data ava...
