We present a new approach to regulate traffic-related pollution in urban environments by utilizing hybrid vehicles. To do this, we orchestrate the way that each vehicle in a large fleet combines its two engines based on simple communication signals from a central infrastructure. Our approach can be viewed both as a control algorithm and as an optimization(More)
Preeclampsia (PE) is characterized by widespread endothelial damage with hypertension, proteinuria, glomeruloendotheliosis and elevated soluble Flt-1 (sFlt-1), a natural occurring antagonist of vascular endothelial growth factor (VEGF). Cancer patients receiving anti-VEGF therapy exhibit similar symptoms. We suggested that a decrease in circulating sFlt-1(More)
Adipose tissue growth depends on angiogenesis. We tested the hypothesis that adipose tissue produces factors relevant to angiogenesis. We obtained fat biopsies in 2 different patient cohorts, cultured adipose-derived stem cells and studied mature adipocytes. We performed microarray, RT-PCR, and Western blotting; studied a rat obesity/metabolic syndrome(More)
