The Rich Get Richer: Brain Injury Elicits Hyperconnectivity in Core Subnetworks
There remains much unknown about how large-scale neural networks accommodate neurological disruption, such as moderate and severe traumatic brain injury (TBI). A primary goal in this study was toExpand

Content-Driven Detection of Cyberbullying on the Instagram Social Network
We study detection of cyberbullying in photo-sharing networks, with an eye on developing early-warning mechanisms for the prediction of posted images vulnerable to attacks. Given the overwhelmingExpand

Opinion Dynamics in the Presence of Increasing Agreement Pressure
In this paper, we study a model of agent consensus in a social network in the presence increasing interagent influence, i.e., increasing peer pressure. Each agent in the social network has a distinctExpand

A voxelwise approach to determine consensus regions-of-interest for the study of brain network plasticity
Despite exciting advances in the functional imaging of the brain, it remains a challenge to define regions of interest (ROIs) that do not require investigator supervision and permit examination ofExpand

Trees with maximal second Zagreb index and prescribed number of vertices of the given degree
In this paper we present a simple algorithm for calculating the maximal value of the second Zagreb index for trees with prescribed number of vertices of given degree. The user needs only to inputExpand
