The added frustration factor destroys the gradient structure, but the modified model is more widely used in practice. In this paper, we study how frustration factors influence the synchronization transition of coupled oscillators in the Sakaguchi-Kuramoto model with frequency mismatch rules. The results show that in the system of coupled oscillators, the frustration factor manifests a disorder field, which restrains the explosive synchronization and weakens the synchronization ability of the whole network. In addition, it is found that the frequency synchronization can not be detected by the common phase order parameter, so a new index is introduced to characterize the degree of frequency synchronization. As an example, at the end of the paper, we theoretically analyze the synchronization dynamics of two-oscillator system, and indirectly verify the correctness of simulations for the multi-body system.展开更多

The aim of this study was to develop a simple, fast, and accurate method for determining arginine in grape juice with Sakaguchi reaction by separating arginine with strong cation-exchange resins. Parameters were optimized including the concentrations of 8-hydroquinoline and sodium hydrobromite. The color stability lasted for 4 min, which is sufficient to finish the measurement. The method is simple, reproducible and accurate, and can be applied for quick measurement of arginine in grape juice to take necessary measures for controlling the level of ethyl carbamate.展开更多
