BACKGROUND Established methods to determine asynchrony suffer from high intra- and interobserver variability and failed to improve patient selection for cardiac resynchronization therapy (CRT). Thus, there is a need for easy and robust approaches to reliably assess cardiac asynchrony. METHODS AND RESULTS We performed echocardiography in 100 healthy subjects and 33 patients with left bundle br...

Estimates Calculating Algorithms have a long story of application to recognition problems. Furthermore they have formed a basis for algebraic recognition theory. Yet use of ECA polynomials was limited to theoretical reasoning because of complexity of their construction and optimization. The new recognition method “AVOpolynom” based upon ECA polynomial of simple structure is described.

Rock physical model and amplitude variation with offset (AVO) patterns considering the content of organic matter composition minerals have a wider significance for guiding identification prediction mud-rich source rock. A rock is proposed describing elastic properties kerogen in different maturity stages. The builds an intrinsic connection between parameters rock, thereby providing theoretical ...

The ability to create subsurface images whose amplitudes are proportional the elastic wavefield variations recorded within seismic data as a function of reflection angle is fundamental for performing accurate amplitude-variation-with-offset (AVO) analysis and inversion. A process that generates such commonly referred true-amplitude migration. We have determined how extended subsurface-offset im...

Abstract The Prediction of the reservoir characteristics from seismic amplitude data is a main challenge. Especially in Nile Delta Basin, where subsurface geology complex and reservoirs are highly heterogeneous. Modern characterization methodologies spanning around attributes analysis, deterministic stochastic inversion methods, Amplitude Variation with Offset (AVO) interpretations, stack rotat...

Cardiovascular diseases (CVDs) are the world's leading cause of death; therefore cardiac health human heart has been a fascinating topic for decades. The electrocardiogram (ECG) signal is comprehensive non-invasive method determining health. Various practitioners use ECG to ascertain critical information about heart. In this paper, noisy denoised based on Discrete Wavelet Transform (DWT) optimi...

Dear Editor, Post-traumatic stress disorder (PTSD) is an anxiety disorder that can arise after exposure to a terrifying event/ordeal in which severe physical harm occurred or was about to happen. PTSD symptoms include persistent re-experience of the trauma, avo idance o f t rauma-assoc ia ted s t imul i , and hyperarousal. In the present report, we describe a woman with PTSD whose symptoms were...
