Group navigation of a constrained environment can be difficult to achieve without jamming as the local density of the group increases. The ease with which insects and other cognitively simple organisms achieve this feat suggests that a distributed computing solution must be possible.

The aperiodic, broadband components of many aggregated electrophysiological recordings such as LFP, EEG and ECoG exhibit characteristic features, notably power-law scaling and a spectral knee. These features of the power spectral density (PSD) vary with behavioral state, arousal, pharmacological interventions, and are linked to transitions between distinct brain states.

Structural discrimination can sustain underrepresentation even when no actor explicitly excludes a group. The authors developed a simple population model in which current representation changes each type’s per-capita effective rate of maintaining or expanding its presence, while corrective action responds to the gap from a reference-population share.

Understanding social polarization requires integrating insights from psychology, sociology, and complex systems science. This study introduces a novel agent-based model that integrates two cognitive and social mechanisms: the desire to be unique within a group and the tendency to simplify complex information.

The authors study how graph neural networks behave when some edges in a graph are missing or altered. These models are widely used to classify molecules, proteins, and social networks, but their predictions can change if the observed connections are incomplete or noisy. They combine two complementary views of...

Real‑world infection networks are often incomplete since contact tracing cannot capture all infection events. As a result, many infected individuals appear as isolated cases with no recorded epidemiological links. Link prediction methods can be used to reconstruct these missing links, allowing for a more complete representation of the infection network. In this study, two approaches were...

Partisan polarization in the United States is often blamed on the “nationalization” of politics, a trend where local issues are increasingly overshadowed by national partisan conflicts. However, it remains unclear exactly how the underlying structure of our social networks interacts with these overarching nationalized signals to sustain such deep societal divides.
