Premature ventricular contraction(PVC) is the most frequent arrhythmia encountered in clinical practice. PVC may occur in health subjects, which is not imminent
We perform first-principles calculation to study the transport properties of the acid dopped on C(4,4) carbon nanotube coupled to two C(4,4) carbon nanotube ele
