Motility is a fundamental feature of living matter, encompassing single cells
and collective behavior. Such living systems are characterized by
nonconservativity of energy and a large diversity of spatiotemporal patterns.
Thus, fundamental physical principles to formulate their behavior are not yet
fully understood. This study explores a violation of Newton's third law in
motile active agents, by considering non-reciprocal mechanical interactions
known as odd elasticity. By extending the description of odd elasticity to a
nonlinear regime, we present a general framework for the swimming dynamics of
active elastic materials in low-Reynolds-number fluids, such as wavelike
patterns observed in eukaryotic cilia and flagella. We investigate the
nonlocal interactions within a swimmer using generalized material elasticity
and apply these concepts to biological flagellar motion. Through simple
solvable models and the analysis of Chlamydomonas flagella waveforms and
experimental data for human sperm, we demonstrate the wide applicability of a
nonlocal and non-reciprocal description of internal interactions within
living materials in viscous fluids, offering a unified framework for active
and living matter physics.

運動性是生物體的基本特徵，包括單細胞和集體行為。這種生命系統的特徵是能量的非保
守性和時空模式的多樣性。因此，制定其行為的基本物理原理尚未完全理解。

這項研究探討了運動黏性劑對牛頓第三定律的違反。
