Community Structure in Time-Dependent, Multiscale, and Multiplex Networks
TLDR
A generalized framework of network quality functions was developed that allowed us to study the community structure of arbitrary multislice networks, which are combinations of individual networks coupled through links that connect each node in one network slice to itself in other slices. Expand
Dynamic reconfiguration of human brain networks during learning
TLDR
This work investigates the role of modularity in human learning by identifying dynamic changes of modular organization spanning multiple temporal scales and develops a general statistical framework for the identification of modular architectures in evolving systems. Expand
Social Structure of Facebook Networks
TLDR
The social structure of Facebook “friendship” networks at one hundred American colleges and universities at a single point in time is studied, finding for example that common high school is more important to the social organization of large institutions and that the importance of common major varies significantly between institutions. Expand
Comparing Community Structure to Characteristics in Online Collegiate Social Networks
TLDR
This study examines the importance of common high school affiliation at large state universities and the varying degrees of influence that common major can have on the social structure at different universities, indicating that university networks typically have multiple organizing factors rather than a single dominant one. Expand
Communities in Networks
TLDR
To help ease newcomers into the field, a guide to available methodology and open problems is provided, and why scientists from diverse backgrounds are interested in community detection is discussed. Expand
Robust Detection of Dynamic Community Structure in Networks
TLDR
This work considers the use of statistical null models for facilitating the principled identification of structural modules in semi-decomposable systems and develops a method to construct representative partitions that uses a null model to correct for statistical noise in sets of partitions. Expand
Rigid fluid: animating the interplay between rigid bodies and fluid
We present the Rigid Fluid method, a technique for animating the interplay between rigid bodies and viscous incompressible fluid with free surfaces. We use distributed Lagrange multipliers to ensureExpand
Task-Based Core-Periphery Organization of Human Brain Dynamics
TLDR
The results demonstrate that core-periphery organization provides an insightful way to understand how putative functional modules are linked, which enables the prediction of fundamental human capacities, including the production of complex goal-directed behavior. Expand
Melting and flowing
TLDR
This work presents a fast and stable system for animating materials that melt, flow, and solidify by physical simulation of fluids --- in particular the incompressible viscous Navier-Stokes equations with free surfaces, treating solid and nearly-solid materials as very high viscosity fluids. Expand
Core-Periphery Structure in Networks
TLDR
This paper develops a new method to investigate the meso-scale feature known as core-periphery structure, which entails identifying densely connected core nodes and sparsely connected peripheral nodes in a network. Expand
