Phase diagram of Josephson junction arrays with capacitive disorder

We study the phase diagram at finite temperature of Josephson junction arrays with capacitive disorder (i.e., random offset charges and/or random charging energies): in the limit of large particle numbers per junction, this is a remarkable physical realization of the disordered boson Hubbard model. By using a mean-field approximation, we compute the average free energy and the equation for the phase boundary line between the insulating and the superconducting phase. We find that the Mott-insulating lobe structure disappears for large variance (\u3c3 73e) of the offset charges probability distribution. Further, with nearest-neighbor interactions, the insulating lobe around q=e is destroyed even for small values of \u3c3. In the case of random charging energies, until the variance of the distribution reaches some critical value the superconducting phase increases in comparison to the situation in which all self-capacitances are equal

Aging and Exercise: A Health Perspective

Habitual exercise provides protection against fatal coronary heart disease, extends longevity, and enhances quality of life. National surveys show less physical activity in older men and women compared with middle-aged and younger persons; older women are particularly sedentary. Although there are still few longitudinal studies on exercise and physical activity in older individuals, the data support a positive relationship between physical activity and health function in older individuals. The data further show that with regular physical activity, health and fitness are maintained or even increased over time in older individuals. Studies on physical activity requirements for beneficial health effects in the elderly are reviewed and presented, and exercise recommendations for older individuals are given
