The influence of fractal heterogeneity on a spiral wave in an excitable system is numerically studied based on the Barkley model. The heterogeneity is implemented by letting the diffusive coefficient in the heterogeneous area be different from the other area. The results show that fruitful...

Based on a deterministic cell cycle model, the mesoscopic stochastic differential equations are theoretically derived from the biochemical reactions. The effects of the finite cell size on the cell cycle regulation in the wild type and wee1-cdc25Δ double mutant type are numerically studied by...

Hydrogen production from ethanol by non-thermal arc discharge was investigated in a novel miniaturized plasma reactor. It is observed that ethanol–water mixture was converted into hydrogen, carbon monoxide and other products. The V–I characteristic was recorded by an oscilloscope to study...

On the basis of the analysis of main problems existing in current agricultural meteorological service in China, for the purpose of exploring a solution to the “last kilometer†problem in rural meteorological service, this article designed four short message service products with the...

The Young's moduli of electrodeposited Ni with different dimensions were measured carefully in this paper. The dimensions of tensile specimens were 200, 35, or 5 μm thick and 2400, 200 or 50 μm wide. These specimens were measured with three different approaches. The measured Young's moduli of...

In order to rank and cluster the economic status of rural residents in 31 provinces, cities and autonomous regions, the MATLAB software is used and the component analysis and the cluster analysis are conducted on the data reflecting the economic status of each area. The results show that the...
