BACKGROUND Regular physical activity can help prevent chronic diseases, yet only half of US adults meet national physical activity guidelines. One barrier to physical activity is a lack of safe places to be active, such as bike paths and sidewalks. Complete Streets, streets designed to enable safe access for all users, can help provide safe places for activity. COMMUNITY CONTEXT This communit...

Background: Ciclovias, known in the U.S. as open streets initiatives, close streets to vehicles to increase open space and physical activity opportunities for local communities. In San Francisco, California, the open streets initiative known as Sunday Streets, was founded in 2008 to promote bicycle use in neighborhoods most underserved for recreational resources and experiencing higher than ave...

We define an elliptic equation for Hermitian metrics which is related to the Einstein condition. Solutions to this equation are closely related to Kähler-Einstein metrics, and are automatically Kähler-Einstein when a certain non-positive condition is satisfied by c1(M). Given this, a natural flow equation arises taking Hermitian metrics to Kähler metrics. We prove short time existence and regul...
