The effects of pavement characteristics on rolling resistance heavy vehicles have gained more interest in recent years. Rolling is the result combination independent (but sometimes correlated) physical phenomena that dissipate energy, which can be regrouped under three different main themes. Road roughness (wavelengths between 0.5 and 50 m) causes movements vehicle suspensions, energy. Pavement...

We study the charge density distribution, the electric field profile, and the resistance of an electrostatically created lateral p-n junction in graphene. We show that the electric field at the interface of the electron and hole regions is strongly enhanced due to limited screening capacity of Dirac quasiparticles. Accordingly, the junction resistance is lower than estimated in previous literat...

In parallel with the pediatric obesity epidemic, the incidence of impaired glucose tolerance and type 2 diabetes has increased among youth. Insulin resistance is thought to be central to the pathophysiology of these obesity-related disorders. A growing body of literature suggests that exercise may ameliorate insulin resistance and thus potentially reduce the long-term diabetes risk in overweigh...
