The warming of permafrost soils and the resulting change in soil respiration (Rs) is one of the most uncertainties in research on global change. To better understand the effect of warming on permafrost soils and the feedback of Rs to climatic warming, a manipulative warming experiment was conducted with two warming levels (low- and high-level warming; increases of 1.88 °C (W1) and 3.19 °C (W2) in...
Global warming and land-use change could have profound impacts on ecosystem carbon (C) fluxes, with consequent changes in C sequestration and its feedback to climate change. However, it is not well understood how net ecosystem C exchange (NEE) and its components respond to warming and mowing in tallgrass prairie. We conducted two warming experiments, one long term with a 1.7°C increase in a C4-dominated...
This paper considers a group of mobile agents moving in Euclidean space with switched network topology. We propose a feedback control algorithm that achieves velocity consensus with weighted directed switched velocity graph and stabilize all position neighboring agents inter-distance to a same desired value. The main results are that the position and velocity graph remaining connected are satisfied...
