space-time phase transitionThermodynamic conventions suffer from describing systems in motion, especially when the structural and energetic changes induced by localized rare events are insignificant. By using the ensemble theory in the trajectory space, we present a statistical approach to address this ...
spin-1/2 Ising system under the presence of a time-varying (sinusoidal) external magnetic field within the path probability method (PPM) of Kikuchi and we observe that the PPM gives exactly the same result as with the Glauber-type stochastic dynamics based on the mean-field theory (DMFT). ...
By developing a mean-field theory, which we verify by simulations, we find coupled collective phenomena, including multistability, regions of coexistence, and macroscopic chaos. In interdependent dynamics, in particular, we observe hysteretic behaviours with abrupt (hybrid and explosive) transitions, ...
“troubled families,” the dynamic systems approach offers insights that can suggest more targeted interventions. For example, as discussed earlier, an increase in variability in parent-adolescent interactions and relationship disequilibrium appears to be “normative” preceding a new phase transition. ...

2), the terms ρij(5), ρab(5), ρia(2), ρai(13), and ρai(14) include unlinked terms implicitly and violate size intensivity of the transition density, too. Simple elimination of the terms leads to a size-intensive theory, which corresponds to the model (II′) in the second-...
transition matrix with a 6-cm standard deviation and the fragmented dynamic was modelled by a uniform transition matrix. The probability of staying in either the continuous or the fragmented movement dynamic was set to 0.968, which corresponds to 62.5 ms of staying in the same movement ...
At temperatures above 450 °C, the sources of weakness such as grain boundaries and phase transition of silicon are depleted, as a result the decrease in fracture toughness is not as significant as that in other temperature ranges. 5.6 Dynamic testing method for rocks with water The water ...
The non-equilibrium phase transition phenome. 关联白噪声驱动的具有时间延迟的Logistic系统可更真实的反映肿瘤细胞的增长问题,本文通过小时间延迟近似方法对由关联白噪声驱动的具有时间延迟的Logistic系统进行了研究,得到了系统的稳态概率密度,并进一步分析了加性和乘性噪声强度,噪声关联时间和时间延迟对稳态概率密度的影...
