Background. Stress thallium scintigraphy provides important diagnostic and prognostic information in patients with coronary artery disease by demonstrating regional myocardial ischemia. However, if the clinical question being addressed is whether a region is viable and not whether there is inducible ischemia, then it may be more reasonable to perform rest-redistribution imaging rather than stre...

This letter describes an alternative solution to passive and active filter arrangements on the dc side of the converter. The circuits of dc-side ripple elimination are based on direct reinjection of the ripple in series with the dc line.

Skyrocketing prices of fuel and increasing concerns towards achieving lower carbon footprints favor any improvements a greener transportation ecosystem. In this work we focus on missed approaches, which are forced maneuvers at the end regular flights that generate significant noise pollution levels near airports. previous introduced reinjection technique for maneuver able to substantially mitig...

Success of a reinjection process depends on the method used for estimating the thermal -ugh time. Estimating the thermal breakthrough time may be based solely on tracer data. Alternatively. it may be estimated solely by using thermal interference tests. While the tracer method usually yields ambiguous estimates, thermal interference tests are infeasible because durations of these tests are simi...

We use the natural invariant density of map and Perron–Frobenius operator to analytically evaluate statistical properties for chaotic intermittency. This study can be understood as an improvement previous ones because it does not introduce assumptions about reinjection probability function in laminar interval or at pre-reinjection points. To validate new theoretical equations, we a symmetric no...

In patients with chronic coronary artery disease and left ventricular dysfunction, the distinction between ventricular dysfunction arising from myocardial fibrosis and ischemic, but viable, myocardium has important clinical implications. By positron emission tomography (PET), enhanced fluorine-18-labeled fluorodeoxyglucose (FDG) uptake in myocardial segments with impaired function and reduced b...

Re-injection of produced geothermal water for pressure support is a common practice in geothermal field management. The location selection of the reinjection well and the rate of injection is a challenging subject for geothermal reservoir engineers. The goal of optimization for this type of problem is usually to find one or more combinations of geothermal re-injection well locations that will m...

It is reported that the characteristic relations of type-II and type-III intermittencies, with respective local Poincaré maps of xn+1 = (1+ǫ)xn+ax 3 n and xn+1 = −(1 + ǫ)xn − ax3n, are both −ln(ǫ) under the assumption of uniform reinjection probability. However, the intermittencies have various characteristic relations such as ǫ−ν (1/2 ≤ ν ≤ 1) depending on the reinjection probability. In this ...
