The spread of Spartina alterniflora (smooth cordgrass) has put biodiversity and ecosystem function at risk since it was introduced to China just a few decades ago. A better understanding how the range S. will expand in future help manage invasion this species coastal wetlands. However, is difficult model extent saltmarshes China. To address issue, we combined multi criteria evaluation with trad...

The evolution of water and land resource carrying capacity significantly impacts optimal allocation regional sustainable development in arid regions. This study proposes a model that combines cellular automaton (CA) Markov; this aids predicting spatial changes availability. In study, taking the Jingdian Irrigation District China’s northwest region as an example, we used long-series monitoring d...

Type-II ryanodine receptor channels (RYRs) play a fundamental role in intracellular Ca(2+) dynamics in heart. The processes of activation, inactivation, and regulation of these channels have been the subject of intensive research and the focus of recent debates. Typically, approaches to understand these processes involve statistical analysis of single RYRs, involving signal restoration, model e...

In this paper, we use a discrete Markov chain model to analyze the throughput of CSMA/CA protocols in a wireless local area network (WLAN) considering the capture phenomenon, which means the packet with the strongest power may capture the receiver even in the presence of other overlapping packets. The model of capture effect over the theoretical throughput of CSMA/CA protocols in the presence o...
