Statistical physics has proven to be a fruitful framework to describe phenomena outside the
realm of traditional physics. Recent years have witnessed an attempt by physicists to study …

Delay tolerant networks (DTNs) may lack continuous network connectivity. Routing in DTNs
is thus challenging since it must handle network partitioning, long delays, and dynamic …

Introduced in its contemporary form in 1946 (ref. 1), but with roots that go back to the
eighteenth century 2, the gravity law 1, 3, 4 is the prevailing framework with which to predict …

How can we localize the source of diffusion in a complex network? Because of the
tremendous size of many real networks—such as the internet or the human social graph—it …

Novel aspects of human dynamics and social interactions are investigated by means of
mobile phone data. Using extensive phone records resolved in both time and space, we …

Suppose that a rumor originating from a single source among a set of suspects spreads in a
network, how to root out this rumor source? With the a priori knowledge of suspect nodes …

We advance a framework for understanding why and how gossip may promote generosity
and cooperation, especially in situations that can result in greater indirect benefits from …

Compared with the epidemic spreading, rumor spreading has some specific characteristics.
In this paper, we supplement some realistic conditions on previous rumor spreading models …

Online social networks (OSNs), as multilingual communication platforms, provide great
convenience for rumor spreading. However, a great deal of negative impacts on individuals …

Spread over complex networks is a ubiquitous process with increasingly wide applications.
Locating spread sources is often important, eg finding the patient one in epidemics, or …
