The nifedipine effect was studied in 8 extrinsic asthmatic subjects with exercise-induced asthma. Before the exercise the patients received, in a randomized double-blind manner, either 20 mg nifedipine, sublingually or sodium cromoglycate by inhalation on 2 separate days. Nifedipine and sodium cromoglycate in all patients inhibited the exercise fall in(More)

The cutoff rates for a discrete memoryless multiple access channel are important not only as measures of the maximum achievable data rates in practice but also as parameters in performance calculations. These parameters are evaluated for the case of hard decision signal detection on an L user channel with an M-ary signal set. Examples of applications are(More)
Higher plasma concentrations of the N-terminal fragment of brain natriuretic peptide (NT-pro-BNP) and the tumor necrosis factor-alpha (TNF-alpha) have been observed in patients affected by chronic heart failure (CHF). Recent clinical studies have tried to correlate the plasma levels of these biomarkers with severity of the disease. To evaluate the role of(More)
In a typical communication circuit, high power amplifiers are commonly used to increase the strength of a transmitted signal. Such amplifiers often operate near saturation and, hence, give rise to nonlinear effects that can degrade performance. The nonlinear effects of an amplifier at a specified frequency may be quantified by the AM/AM and AM/PM, the(More)
