It is well known that information is encoded in the frequency or amplitude of Ca2+ signal and then decoded by target protein. However, few models considered both the encoding and decoding procedures of Ca2+ signal. In this work, a minimal Li–Rinzel model is coupled with a...

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...

In this paper, the age-hardening behavior and phase transformation of Mg-9.2Gd-1.9Y-1.8Zn-0.5Zr alloy were systematically studied. The results showed that the aging strengthening effect of the alloy is significant at 225°C. In under-aging stage, the second phases are mainly nucleation,...
