    A resource-rational theory of set size effects in human visual working memory

    Ronald van den Berg, Wei Ji Ma
    Set size effects in visual working memory are explained as a resource-rational trade-off between an error-based behavioral cost and a neural encoding cost.

    Competition for fluctuating resources reproduces statistics of species abundance over time across wide-ranging microbiotas

    Po-Yi Ho, Benjamin H Good, Kerwyn Casey Huang
    A simple model provides an accessible framework to infer macroscopic parameters of effective resource competition from longitudinal studies of microbial communities.

    Resource allocation accounts for the large variability of rate-yield phenotypes across bacterial strains

    Valentina Baldazzi, Delphine Ropers ... Hidde de Jong
    A coarse-grained model of microbial growth coupling fluxes of carbon and energy shows that resource allocation is a major explanatory factor of the observed variability of growth rates and growth yields across different bacterial strains.

    Multistability and regime shifts in microbial communities explained by competition for essential nutrients

    Veronika Dubinkina, Yulia Fridman ... Sergei Maslov
    Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.

    Expansion and contraction of resource allocation in sensory bottlenecks

    Laura R Edmondson, Alejandro Jiménez Rodríguez, Hannes P Saal
    A simple efficient coding model predicts complex trade-offs in resource allocation for sensory inputs with heterogeneous receptor densities and activation levels.

    A mechanistic insight into sources of error of visual working memory in multiple sclerosis

    Ali Motahharynia, Ahmad Pourmohammadi ... Mehdi Sanayei
    Imprecision in decoding information and swap error, that is, mistakenly reporting a non-target feature, contributes to working memory deficit in the multiple sclerosis population.

    Environmental fluctuations reshape an unexpected diversity-disturbance relationship in a microbial community

    Christopher P Mancuso, Hyunseok Lee ... Ahmad S Khalil
    Laboratory experiments using a microbial community and mathematical modeling reveal how environmental disturbances can predictably alter the diversity and composition of an ecosystem.

    Microbial consortia at steady supply

    Thibaud Taillefumier, Anna Posfai ... Ned S Wingreen
    In a consumer-resource model obeying the physical requirement of flux conservation, metabolic competition between microbes yields consortia of cell types that collectively resist invasion via optimal use of resources.

    Mapping the function of neuronal ion channels in model and experiment

    William F Podlaski, Alexander Seeholzer ... Tim P Vogels
    The ion channel genealogy resource is a comprehensive and intuitive comparison tool for ion channel models and experimental data, helping to visualize their similarity and function to facilitate better experimentally-constrained modeling.
