Tracking the Evolution of Communities in a Social Network of Intellectual Influences
Journal of Historical Network Research, 2022 The history of intellectuals consists of a long-spanning entangled web of influences, interdependencies, and inspirations. In this paper, we construe the history of intellectuals by means of a formalized network approach, and structurally analyze how ...

An Enhanced Incremental SVD Algorithm for Change Point Detection in Dynamic Networks
IEEE Access, 2018 Change point detection is essential to understand the time-evolving structure of dynamic networks. Recent research shows that a latent semantic indexing (LSI)-based algorithm effectively detects the change points of a dynamic network.

Rapid report of the 8 January 2022 MS 6.9 Menyuan earthquake, Qinghai, China
Earthquake Research Advances, 2022 The MS 6.9 Menyuan earthquake in Qinghai Province, west China is the largest earthquake by far in 2022. The earthquake occurs in a tectonically active region, with a background b-value of 0.87 within 100 km of the epicenter that we derived from the ...

NetWalk: A Flexible Deep Embedding Approach for Anomaly Detection in Dynamic Networks
Knowledge Discovery and Data Mining, 2018 Massive and dynamic networks arise in many practical applications such as social media, security and public health. Given an evolutionary network, it is crucial to detect structural anomalies, such as vertices and edges whose "behaviors'' deviate from ...

Detecting Community Structure in Dynamic Social Networks Using the Concept of Leadership
, 2017 Detecting community structure in social networks is a fundamental problem empowering us to identify groups of actors with similar interests. There have been extensive works focusing on finding communities in static networks, however, in reality, due to ...

Dynamic master selection in wireless networks [PDF]
, 2011 . Mobile wireless networks need to maximize their network lifetime (defined as the time until the first node runs out of energy). In the broadcast network lifetime problem, all nodes are sending broadcast traffic, and one asks for an assignment of ...
