Rheology and Collective Behavior in Living Tissue
… themselves to a fluid state in order to promote collective motion? Has evolution made use of the ability of tissues to tune themselves between fluid and solid states in programming the complex steps leading from the embryo to the organism? Here we describe our recent e↵orts to answer such …

Collective behavior of confined growing bacterial monolayers
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-03-28 without embargo terms

A rational choice framework for collective behavior
… individual experiences and agendas. When are collectives able to function and thrive despite these challenges? In this thesis I propose a theoretical framework for reasoning about collective intelligence--the ability of people to accomplish their shared goals together. A simple result from the …

Modeling Collective Behavior of Dislocations in Crystalline Materials
A part of this work deals with the kinematics of dislocation density evolution. An explicit Galerkin/least-squares formulation is introduced for the quasilinear evolution equation, which leads to a symmetric and well-conditioned system of equations with constant coefficients, making it attractive …

Neuro-evolution behavior transfer for collective behavior tasks
… attempt over the last decade to incorporate behavior (knowledge) transfer in machine learning so that relevant behavior acquired in previous learning experiences can be used to boost task performance in complex tasks, using evolutionary algorithms to facilitate behavior transfer (especially …

Collective behavior of driven Janus colloids in external fields
Colloids are micron-sized particles widely used in industrial processes and everyday products. Conventional interest has focused on their equilibrium self-assembly structures by engineering static interactions between the colloids. The introduction of the fourth dimension, time, gives rise to a new …

Collective behavior of colloidal suspensions under electric fields and confinement
… In particular, we focus on the dynamics and collective behavior of colloidal suspensions of spherical particles under electric fields and confinement. We first analyze the nonlinear dynamics of non-colloidal, uncharged ideally polarizable spheres freely suspended in a viscous electrolyte in a …

The individual and collective behavior of social organisms across environments
… conditions, and this diversity can drive behavioral variation. For group-living organisms, this variation is present at both the individual and the collective levels, with individual behavioral phenotypes and interactions among individuals driving collective behavior. However, gaps remain …

Impact of Vimentin Intermediate Filaments on 3D Multicellular Collective Behavior
… there are limited studies on its role in collective migration in 3D in vitro. To elucidate vimentin’s role in a collective cell cluster, single MCF-7 cells are embedded in a Matrigel-Alginate gel, which then grow into multicellular systems. The MCF-7 cells utilized are vimentin null, …

Structuralist and interactionist perspectives of collective behavior and control of crowds.
… of this thesis is to understand the concept of collective behavior from different theoretical perspectives and the policy implications they imply for the Turkish Riot Police Units. The civil disturbances in the 1960s have clearly illustrated range of problems in the domain of crowd control. This …

Analyzing the Collective Behavior of Earthquakes to Understand Fault Mechanisms Better
The Gutenberg-Richter law tells us that there is a tenfold increase in the number of earthquakes of magnitude 𝑚 > 𝑀 when 𝑀 decreases by one unit. Thus, the vast majority of earthquakes occur at magnitudes so small that the vibrations they cause can barely be recorded at the surface of Earth. Given …

Collective behavior over social networks with data-driven and machine learning models
… networks also shape their actions. Pervasive behavioral data provides opportunities for a richer view of the decisions on networks. Yet, the increasing volume, complex structures, and dynamics of behavioral data stretch the limit of conventional methods. I develop mathematical modeling (e.g., …

Multiscale Views of Multi-agent Interactions in the Context Of Collective Behavior
In nature, many social species demonstrate collective behavior ranging from coordinated motion in flocks of birds and schools of fish to collective decision making in humans. Such distinct behavioral patterns at the group level are the consequence of local interactions among the individuals. We can …

Collective Behavior of Drosophila Melanogaster Neural Progenitor and Imaginal Disc Cells within Controlled Microenvironments
… by a structure called the Optic Stalk (OS). Collective migration of neural and retinal progenitor cells (RPCs) from the developing brain lobes (DBL) to the Imaginal Disc (ID), through the OS, is a fundamental part of regenerative strategies in retina. Developmental signals governing retinal …

Foraging in a Complex World: From Individual Flight Performance to Collective Behavior in Bumblebees (Bombus Impatiens)
Foraging is a crucial and remarkably complex behavior that is key to survival. For social insects such as bumblebees, successful foraging depends on a combination of individual traits (e.g. physiological and biomechanical performance of individual workers) and collective behavioral strategies for …

Protein structure and interaction under environmental stress : from quality control recognition to evolution of collective behavior
A protein's function in the cell depends on its structure, which in turn depends on the intracellular environment. Stress like heat shock or nutrient starvation can alter intracellular conditions, leading to protein misfolding - i.e. the inability of a protein to reach or maintain its native …

Modeling phase synchronization of interacting neuronal populations : from phase reductions to collective behavior of oscillatory neural networks
… systems. This allows for capturing the collective dynamics of coupled oscillators when additional parameters influence the individual dynamics. Chapter 6 draws the line to experimental data. The phase time series of resting state MEG data display large-scale brain activity at the edge of …
