Mapping the connections inside Russia's APT Ecosystem - Check Point Research For the first time, thousands of Russian APT samples were gathered, classified and analyzed in order to map connections between different cyber espionage organizations in Russia.

IMHO the voyager program is among the 10 most amazing achievements of the human race. Today is a good day to celebrate this great project, who among many other accomplishments is responsible to the two farthest nodes of the human communication network, with its sensors still delivering data back to earth.

Extracting Brain Networks from Large-Scale Neural Recordings Dr. Lowry Kirkby will provide an interactive tutorial on extracting brain networks from large-scale neural recordings.

"This review demonstrates how network science approaches have been applied to the study of human cognition and how network science can uniquely address and provide novel insight on important questions related to the complexity of cognitive systems and the processes that occur within those systems. "

Cognitive Network Science: A Review of Research on Cognition through the Lens of Network Representations, Processes, and Dynamics Network science provides a set of quantitative methods to investigate complex systems, including human cognition. Although cognitive theories in different domains are strongly based on a network perspective, the application of network science methodologies to quantitatively study cognition has so fa...

While this is relevant to much more than complex networks, it handles a topic that is very useful for complex networks analysis, addressing a major challenge in figuring out cause and effect. .

"We offer an alternative principle to assess the physiological role of neuronal synchrony based on identifying structural anomalies in the underlying network and studying their impacts on the collective dynamics. In particular, we focus on autapses - time delayed self-feedback links that exist on a small fraction of neurons in the network, and investigate their impacts on network synchronization through a detailed stability analysis."

A protein-protein interaction network (PPIN), a.k.a. protein interactome, can be modeled as an undirected graph: vertices represent proteins and edges represent interactions between proteins.

"Here we describe a technique that allows us to make optimal estimates of network structure from complex data in arbitrary formats, including cases where there may be measurements of many different types, repeated observations, contradictory observations, annotations or metadata, or missing data"

Network structure from rich but noisy data A technique allows optimal inference of the structure of a network when the available observed data are rich but noisy, incomplete or otherwise unreliable.

"We investigate the effects of modular and temporal connectivity patterns on epidemic spreading..... Within this framework, we study the epidemic size of Susceptible-Infected-Recovered, SIR, models and the epidemic threshold of Susceptible-Infected-Susceptible, SIS, models. Interestingly, we find that while the presence of tightly connected clusters inhibits SIR processes, it speeds up SIS phenomena."

This is a most fascinating discovery!
Spiders are, well, connected to complex networks by their very nature. This research shows how they use earth's electric fields (another complex network on its own) for spreading globally. Also, it reveals spiders' sense of these fields as a part of their neuronal system.

"Here, we address two outstanding questions: to what extent are brain hemispheres engaged in a competitive behaviour in terms of nodal centrality? and, how does the importance of each hemisphere rely on interhemispheric connections?"

"Simple contagion refers to spreading processes induced by a single exposure to a contagious entity while complex contagion demands multiple exposures for transmission. Inspired by this observation, we propose a model of contagion dynamics with a transmission probability that initiates a process of complex contagion"
