(TTE) derived gradients and invasive RV-PA peak-to-peak systolic gradient (iPG) and the predictability of these values in children with pulmonary valve stenosis (PVS).#Introduction:Historically, correlations have been found between the Doppler-derived peak echo gradient (ePG), using the modified ...
OBJECTIVE: We sought to identify a time during cardiac ejection when the instantaneous pressure gradient (IPG) correlated best, and near unity, with peak-to-peak systolic ejection gradient (PPSG) in patients with congenital aortic stenosis. Noninvasive echocardiographic measurement of IPG has limited...

(note that Eurasian region extends from central Asia to the western fringe of East Asia) shows that the reduction of aerosol concentration in the midlatitude resulting to more pronounced warming, which leads to a weaker meridional temperature gradient that consequently weakens the subtropical jet ...
We extend the tone reservation technique to the out-of-band carriers, and design efficient methods for constructing OFDM signals with lower PAR. Two approaches are investigated, one based on a gradient algorithm, and another that uses random sequences. Simulation results show that our technique ...
Two approaches are investigated, one based on a gradient algorithm and another that uses random sequences. Simulation results show that the authors' techniques can provide PAR reduction without the loss in data rate. 展开 关键词: peak-to-average power ratio PAR underwater acoustic communications ...
Every MICE visitor agrees that The Peak Tram is one authentic side to the city that can't be missed. The 1.27 km scenic trip to the one of the highest points on Hong Kong Island passes through a kaleidoscope of history, moving through the city's leafy interior, on a steep gradient ...
Peak flowacross themitral valvenormally equals or exceeds the peak flow rate across theaortic valve. The rapid movement of blood from theleft atriuminto theleft ventriclein early diastole is due to a pressure gradient from the left atrium all the way to theLV apex(Fig. 7-6A).102Ventricular...

The subcarriers used to reduce the PAPR are called the peak reduction tone sets. The mechanism of peak-canceling signal generation is a primary factor in determining the quality of the PAPR reduction performance of the TR technique. Currently, two signal generation mechanisms exist: TR-gradient-...
