Natural Frequency Method: estimating the preferred walking speed of Tyrannosaurus rex based on tail natural frequency. [PDF]
R Soc Open Sci, 2021 Locomotor energetics are an important determinant of an animal's ecological niche. It is commonly assumed that animals minimize locomotor energy expenditure by selecting gait kinematics tuned to the natural frequencies of relevant body parts. We demonstrate that this allows estimation of the preferred step frequency and walking speed of

Synchronization in phase oscillator networks with “ring” and “small world” link topologies and different dependences of the oscillator frequency on its network location [PDF]
Известия Саратовского университета. Новая серия: Физика, 2023 Background and Objectives: In this paper, we consider the general case of the establishment/destruction of a completely synchronous state of phase oscillator networks with topologies of links such as “ring” and “small world”.
