Seek Distances in Two-Headed Disk Systems

We make a correction to the calculation of mean seek time in a recent algorithm of intelligently positioned two headed disk systems. We also introduce a new two headed disk system with better mean seek time.

Premature Ventricular Complexes and Left Atrial Appendage Dysfunction - Another Head on a Many-Headed Hydra ?

Premature ventricular complexes (PVCs) in the absence of structural heart disease are often, but not always benign. They may require treatment for symptoms produced by the PVCs themselves or for intermittent sustained ventricular tachycardia. Even in the absence of symptoms, frequent premature ventricular complexes may lead to the development of left ventricular systolic dysfunction as a form o...
