Paleontologists must confront the challenge of studying the forms and functions of extinct
species for which data from preserved fossils are extremely limited, yielding only a …

Locomotion of aquatic animals involves flapping of their body to generate lift and thrust.
Through evolution, they have mastered their ability to move through complex environments …

A strong micro heat engine that can be used in the untethered state is essential for next-
generation microrobotics. Here, we propose a rapid swimmer using explosive boiling due to …

We computationally study the propulsive performance of a two-dimensional elliptic foil
undergoing interlinked pitching-heaving motion. This motion is realized by pitching the foil …

Fish schooling is a common phenomenon that is assumed to have energy advantages, and
various fish schooling configurations have been observed. However, the underlying …

Dragonflies can independently control the movement of their forewing and hindwing to
achieve the desired flight. In comparison with previous studies that mostly considered the …

The fluid mechanics underlying the collective motion of fish schools and bird flocks still lack
full understanding. In this paper, the collective motion of multiple asynchronous flapping foils …

This study introduces novel physics-based scaling laws to estimate the propulsive
performance of synchronously pitching foils in various schooling configurations. These …

Body size is the key to understanding many biological properties. Sizes of extinct animals
are usually estimated from body reconstructions since their masses can not be weighed …
