A scheme is proposed for the remote preparation of an arbitrary two-particle quantum state by using two nonmaximally entangled states as the quantum channel. The effects of the environment noise on the quantum channels are considered, in which the time-evolution is ruled by the master equations of the density matrices in the Lindblad form. We investigated the influence of environment noise on the...
Cardiogram recordings include numerous noncardiac containments, which overlap with the cardiac components in the frequency domain. Despite the rich literature in ECG denoising field, there are still noise left in the ECG. Useful information can not be extracted from such ECG. Therefore, the detection ECG validity algorithm was proposed based on wavelet transform. First, signals were preprocessed by...
T-wave alternans (TWA) is a variation in the amplitude or morphology of the T wave of the beat-to-beat ECG which provides a noninvasive and clinically useful marker for the risk of sudden cardiac death (SCD) caused by life threatening arrhythmias. Detection of beat-to-beat microvolt fluctuation of the T wave has been made possible with the use of advanced signal processing techniques and high-resolution...
