WebApr 1, 2024 · In particular, the truncated Lévy-walk model with rests is well-suited to describe the HMF dynamics in equilibrium. Another point to note here is that the non-stationary dynamics of the HMF model, associated with the transition QSS → BG, leaves an imprint on the time dependence of α , which is observed as a plateau α ≃ 1.5 . WebFeb 1, 2024 · Thus, researchers often use a truncated Lévy distribution to model the distances that an animal travels in one unit of time. For example, an albatross can fly up …

Although this transposition event could render the PKS inactive, it does not necessarily have to (see Discussion). The starter module consists of a KS S domain (active-site cysteine replaced by serine), which is similar to starter modules of polyene polyketide synthases, …
WebThe Lévy walk is a pattern that is often seen in the movement of living organisms; it has both ballistic and random features and is a behavior that has been recognized in various animals and unicellular organisms, such as amoebae, in recent years. We proposed an amoeba locomotion model that implements Bayesian and inverse Bayesian inference as a Lévy …
