background: delayed or missed diagnosis of critical and cyanotic congenital heart disease (chd) in asymptomatic newborns may result in significant morbidity and mortality. the aim of this study was to determine the accuracy of pulse oximetry screening  performed on the first day of life for the early detection of critical and cyanotic chd in apparently normal newborns. methods: this cross-secti...

In this paper a new fast mode decision method for H.264 /AVC intra coding is developed, which is based on the analysis of edge filter and more efficient mode selection. We analysis the edge detection algorithm from the perspective of edge filters and make it more efficient at mode selecting. In the proposed edge filters, differ from those existing methods which select several neighbor modes onl...

BACKGROUND SonoVue is a new microbubble contrast agent containing sulfur hexafluoride. We assessed the efficacy of SonoVue myocardial contrast echocardiography (MCE) to detect resting perfusion abnormalities. METHODS Nineteen adult patients with a wall motion abnormality in a screening echocardiogram were studied. Each patient received up to four bolus injections of 2.0 mL SonoVue (Bracco Dia...

Based on the transfer-matrix method, we theoretically explore transmission and reflection properties of light waves in a one-dimensional defective photonic crystal composed superconductor (HgBa2Ca2Cu3O8+?) semiconductor (GaAs) layers. The whole system is centrosymmetric can generate defect peak band gap. We study effect temperature mode. Results obtained show that mode shifts to lower frequency...
