BACKGROUND: Recurrent-episode Major Depressive Disorder (MDD) is associated with a
number of neuropsychological deficits. To date, less is known about whether these are …

Random walks are ubiquitous in the sciences, and they are interesting from both theoretical
and practical perspectives. They are one of the most fundamental types of stochastic …

Despite the success of traditional network analysis, standard networks provide a limited
representation of complex systems, which often include different types of relationships (or ‘…

In most natural and engineered systems, a set of entities interact with each other in complicated
patterns that can encompass multiple types of relationships, change in time and include …

Network science is an interdisciplinary endeavor, with methods and applications drawn
from across the natural, social, and information sciences. A prominent problem in network …

… in brain signals also supports mental effort in a variety of cognitive operations (50), presumably
by aiding the brain in switching between different network configurations as it masters a …

… Such techniques start with a matrix that indicates similarities (eg, a tabulation of how every
legislator voted on every bill) and return a coordinate matrix that minimizes an appropriate …

A network representation is useful for describing the structure of a large variety of complex
systems. However, most real and engineered systems have multiple subsystems and layers of …

We study the social structure of Facebook “friendship” networks at one hundred American
colleges and universities at a single point in time, and we examine the roles of user attributes–…

Persistent homology (PH) is a method used in topological data analysis (TDA) to study
qualitative features of data that persist across multiple scales. It is robust to perturbations of input …
