Linking Density and Nanoscale Crystallinity to Hydration in Nafion PEMFC Membranes: Insights From Experiment and Molecular Dynamics Simulations

open access: yesSmall Structures, EarlyView.
Molecular dynamics and experimental analysis show that higher crystallinity in Nafion enhances molecular packing, thereby increasing effective density. A proposed model bridges experimental and molecular‐scale observations by quantitatively linking water uptake to density variations, offering a predictive framework for optimising hydration and ...

Home range and core area characteristics of urban and rural coyotes and red foxes in southern Wisconsin

open access: yesWildlife Biology, EarlyView.
Second‐order habitat selection is influenced by a variety of factors, including individual‐ and species‐specific traits and resource requirements, as well as landscape characteristics. By comparing home range characteristics across individuals, species, and landscapes, we can draw conclusions regarding whether and how different factors influence home ...

Distributed Formation Control for Heterogeneous Robot Systems Based on Competitive Mechanism

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper presents an adaptive formation control method for a heterogeneous robot swarm, utilising a multilevel formation task tree to model various types of formation tasks and a single‐state distributed k‐winner‐take‐all (S‐DKWTA) algorithm to address the MRTA problem.
