To study the coupling mechanism between droplet evaporation characteristics and flame propagation, in this paper, the ignition process in a single dome lean direct injection combustor is simulated by the Large Eddy Simulation (LES) method. A new concept, i.e., available droplet, and a new parameter,...

Fertilization management constitutes a critical determinant of agroecosystem productivity. Reasonable fertilization can increase the organic matter content in soil; however, the potential mechanism of how different fertilization regimes impact soil carbon sequestration is unclear. We hypothesized th...

Anthocyanins are important metabolites that provide a red or blue–purple hue to plants. The biosynthesis of these metabolites is mainly activated by the MYB-bHLH-WD40 (MBW) complex and repressed by a wide variety of proteins. Studies have shown that MYB activators activate MYB repressors to balance...
