摘要：
生命体能够消耗化学能，并独立于其他个体处理信息。不过，生命体可以通过协作形成有序群体，例如鱼群。本研究将这类复杂群体视为生命材料，开展了基于成像的实验室鱼群实验，以探究这种非平衡活性如何影响群体的力学特性。我们利用空间限制来调控准二维鱼群内鱼类的运动与结构。借助图像分析技术，我们对群体结构、空间异质性及其时间波动进行了定量观测。此外，我们利用Monte Carlo（蒙特卡洛）模拟复现了实验观测到的面积分布模式，这为探究鱼类间的有效相互作用提供了思路，并证实了基于限制的行为偏好转变的存在。另外，与短程相互作用系统不同，由于鱼类群体中空间排布与行为动力学之间的复杂相互作用，此处的结构异质性与动态活性呈正相关。
英文摘要：
Living objects are able to consume chemical energy and process information independently from others. However, living objects can coordinate to form ordered groups such as schools of fish. This work considers these complex groups as living materials and presents imaging-based experiments of laboratory schools of fish to understand how this non-equilibrium activity affects the mechanical properties of a group. We use spatial confinement to control the motion and structure of fish within quasi-2D shoals of fish. Using image analysis techniques, we make quantitative observations of the structures, their spatial heterogeneity, and their temporal fluctuations. Furthermore, we utilize Monte Carlo simulations to replicate the experimentally observed area distribution patterns which provide insight into the effective interactions between fish and confirm the presence of a confinement-based behavioral preference transition. In addition, unlike in short-range interacting systems, here structural heterogeneity and dynamic activities are positively correlated as a result of complex interplay between spatial arrangement and behavioral dynamics in fish collectives.
