Abstract We perform the exact TDRG transformations on the kinetic Ising model of the braced ladder whose Rmin is 5. Within our knowledge, this is the only example that the exact TDRG transformations have been performed on a system with Rmin >2. We show that under Achiam's linear response theory there must be important excitations of the multi-spin operators in the kinetic Ising models of the systems with Rmin > 2, the dynamic critical behaviours of the systems are greatly affected by these excitations. Moreover, we get the conclusion that for the kinetic Ising models of the systems with Rmin=$\infty$ exact TDRG calculationa are impossible. The complete new and interesting results are given.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
