The electrocardiogram (ECG) is widely used for diagnosis of heart diseases. Good quality ECG signals are utilized by physicians for interpretation and identification of physiological and pathological phenomena. Several techniques have been proposed to extract the ECG components contaminated with the background noise and allow the measurement of subtle features in the ECG signal. One of the comm...

We give an alternate proof of Wise’s malnormal special quotient theorem (MSQT), avoiding cubical small cancelation theory. We also show how to deduce Wise’s Quasiconvex Hierarchy Theorem from the MSQT and theorems of Hsu and Wise and Haglund and Wise. 2010 Mathematics Subject Classification: 20F67 (20E08)

The infrared structure of MHV gluon amplitudes in N = 4 super Yang-Mills theory is considered in the next-to-leading order of PT. Explicit cancelation of the infrared divergencies in properly defined cross-sections is demonstrated. The remaining finite parts for some inclusive differential cross-sections are calculated analytically. In general, contrary to the virtual corrections, they do not r...

This paper presents a high-speed simultaneous bidirectional transceiver (SBT) for on-chip wireline communications. A MOS hybrid transistor is utilized to split the received data from superimposed signal at both ends of interconnection with assistance two drivers, namely main and auxiliary. Moreover, high-pass filter (HPF) used as differentiator generate echo cancelation signal. Consequently, ec...
