Group size and environmental obstacles drive acoustic call properties for gray bats in flight: A data-driven analysis

Megan Grey; Eighdi Aung; Nicole Abaid

PLOS Complex Systems, Vol. 3 No. 4 · 2026 · Inggris · PLOS Scopus

Unlike schools of fish or flocks of birds, social bats who use echolocation for navigation are faced with the complex challenge of signal processing while living and flying in groups. Interference between an individual’s calls and those of its conspecifics can be confused, making these signals…

Assortativity in geometric and scale-free networks

Marc Kaufmann; Ulysse Schaller; Thomas Bläsius dkk.

PLOS Complex Systems, Vol. 3 No. 4 · 2026 · Inggris · PLOS Scopus

The assortative behavior of a network is the tendency of similar (or dissimilar) nodes to connect to each other. This tendency can have an influence on various properties of the network, such as its robustness or the dynamics of spreading processes. In this paper, we study degree assortativity both…

Characterization of monotone Boolean models supporting fixed points and multistability in balanced networks

Sarah Adigwe; Harshavardhan BV; Mohit Kumar Jolly dkk.

PLOS Complex Systems, Vol. 3 No. 5 · 2026 · Inggris · PLOS Scopus

Gene regulatory networks (GRN) control the expression levels of proteins in cells, and understanding their dynamics is key to potentially controlling disease processes. Steady states of GRNs are interpreted as cellular phenotypes, and the first step in understanding GRN dynamics is describing the…

PLOS Complex Systems, Vol. 3 No. 4 · 2026 · Inggris · PLOS Scopus

We investigate connectivity properties of the SARS-CoV2 spike protein-human ACE2-receptor complex employing a protein side chain-based network method that allows us to span a range from atomic to global protein scales. We analyze network topology in terms of clusters and cliques obtained from…

A typology of rules for knowledge exchange in higher-order interactions

Anna Sisk; Matthew J. Silk; Nakeya D. Williams dkk.

PLOS Complex Systems, Vol. 3 No. 1 · 2026 · Inggris · PLOS Scopus

Social learning is important to humans and other animals as they gather information about their environment. Information and behaviours can therefore spread rapidly through social networks as contagions. However, the way individuals acquire and use social information is highly variable and…

A generalized Bayesian framework for maximizing information gain and model selection

Prem Jagadeesan; Karthik Raman; Arun K. Tangirala

PLOS Complex Systems, Vol. 3 No. 1 · 2026 · Inggris · PLOS Scopus

Computational modelling of dynamical systems often involves many free parameters estimated from experimental data. The information gained from an experiment plays a crucial role in the goodness of predictions and parameter estimates. Optimal Experiment Design (OED) is typically used to choose an…

Inference and training efficiency in pruned multilayer perceptron networks

Amirhossein Douzandeh Zenoozi; Laura Erhan; Antonio Liotta dkk.

PLOS Complex Systems, Vol. 3 No. 3 · 2026 · Inggris · PLOS Scopus

This study explores how pruning strategies can improve the efficiency of deep neural networks (DNNs), which are widely used for tasks like image processing, medical diagnosis, etc. Although DNNs are powerful, they often contain weaker connections that can lead to increased energy consumption both…

Bifurcation, sensitivity, and noise: Stochastic dynamics of cholera with vaccination and sanitation controls

Hailu Tkue Welu; Yohannes Yirga Kefela; Habtu Alemayehu Atsbaha dkk.

PLOS Complex Systems, Vol. 3 No. 4 · 2026 · Inggris · PLOS Scopus

This study develops the novel SVAITRS-B model, unifying deterministic and stochastic frameworks to capture cholera dynamics with vaccination, asymptomatic carriers, and environmental pathways. We demonstrate analytically that person-to-person transmission exhibits backward bifurcation, while…

Algorithmic influence on conflict and cooperation in digital communities

Andrea Russo; Alessandro Caliandro

PLOS Complex Systems, Vol. 3 No. 4 · 2026 · Inggris · PLOS Scopus

This study focus on the contrasting dynamics of discussion and information dissemination on two influential platforms: X and Wikipedia. While X often serves as a battleground for contentious debates, where users engage in direct confrontation, Wikipedia fosters a collaborative environment aimed at…

Research university assortativity conditions the integration of regional innovation systems

Alexander Michael Petersen; Andrea Montaño Ramirez

PLOS Complex Systems, Vol. 3 No. 2 · 2026 · Inggris · PLOS Scopus

Substantial policy efforts to develop regional innovation systems (RIS) highlight the importance of understanding the institutional factors that promote integration and synergy at the regional scale. To this end, we analyzed historical patterns of research co-production within and across California…

Weakly supervised contrastive representation learning to encode narrative viewpoint of COVID-19 tweets

Kin Wai Ng; Nathan Wendt; Jasmine Eshun dkk.

PLOS Complex Systems, Vol. 3 No. 2 · 2026 · Inggris · PLOS Scopus

Viewpoint detection is a crucial step for characterizing online narratives and understanding their diffusion and evolution across online social spaces. Existing methods for semantic understanding of online posts have shown strong progress towards grouping documents with similar topics but struggle…

A green vehicle routing methodology for assessing optimal fleet mix and cost/emissions tradeoffs given environmental policy incentives

Griffin M. Wilson; Richard T. Stone

PLOS Complex Systems, Vol. 3 No. 2 · 2026 · Inggris · PLOS Scopus

Transportation accounts for nearly one quarter of global greenhouse gas (GHG) emissions. A significant proportion of transportation emissions can be attributed to supply chain transport, which also represents the fastest-growing sector of emissions. As a way of addressing this challenge in the…

Correction: Inferring leader-follower behavior from presence data in the marine environment: A case study on Reef Manta Rays

Multiscale mobility: How the COVID-19 pandemic reshaped Mexico’s intermunicipal connectivity

Issa Moussa Diop; Erika Cruz-Bonilla; Christian Wolff dkk.

PLOS Complex Systems, Vol. 3 No. 1 · 2026 · Inggris · PLOS Scopus

Mobility networks are vital for economic activity, social interaction, and urban development, yet they remain highly vulnerable to external shocks. The COVID-19 pandemic profoundly disrupted human mobility, but most studies have focused on short-term responses or macroscopic patterns, leaving…

A dynamic model of segregation and integration: Incorporating adaptive intolerance, media bias, and conformity into the Schelling framework

Joseph D. Johnson; Marisa C. Eisenberg

PLOS Complex Systems, Vol. 3 No. 1 · 2026 · Inggris · PLOS Scopus

Thomas Schelling introduced his agent-based model of segregation in 1971 and concluded that even when there is a low amount of intolerance within society that segregation will develop if people follow their individual preferences. A large body of literature building of this framework has been built…

Fast algorithms to improve fair information access in networks

Dennis Robert Windham; Caroline J. Wendt; Alex Crane dkk.

PLOS Complex Systems, Vol. 3 No. 3 · 2026 · Inggris · PLOS Scopus

We consider the problem of selecting k seed nodes in a network to maximize the minimum probability of activation under an independent cascade beginning at these seeds. The motivation is to promote fairness by ensuring that even the least advantaged members of the network have good access to…
