The power of any kind of network approach lies in the ability to simplify a complex system so
that one can better understand its function as a whole. Sometimes it is beneficial, however …

In this paper, we review some advances made recently in the study of mobile phone
datasets. This area of research has emerged a decade ago, with the increasing availability …

A network is a collection of nodes and edges, where an edge connects two nodes. Many
social, natural and engineered systems can be represented as networks. Examples include …

Well-established fine-scale urban mobility models today depend on detailed but
cumbersome and expensive travel surveys for their calibration. Not much is known …

Human mobility is differentiated by time scales. While the mechanism for long time scales
has been studied, the underlying mechanism on the daily scale is still unrevealed. Here, we …

The possibility to analyze everyday monetary transactions is limited by the scarcity of
available data, as this kind of information is usually considered highly sensitive. Present …

Social systems are in a constant state of flux, with dynamics spanning from minute-by-minute
changes to patterns present on the timescale of years. Accurate models of social dynamics …

User-generated content (UGC) platforms on the Internet have experienced a steep increase
in data contributions in recent years. The ubiquitous usage of location-enabled devices …

Recent research has highlighted limitations of studying complex systems with time-varying
topologies from the perspective of static, time-aggregated networks. Non-Markovian …

Bursty dynamics is a common temporal property of various complex systems in nature but it
also characterises the dynamics of human actions and interactions. At the …
