An agent-based model for interrelation between COVID-19 outbreak and economic activities

As of July, 2020, acute respiratory syndrome caused by coronavirus COVID-19 is spreading over the world and causing severe economic damages. While minimizing human contact is effective in managing the outbreak, it causes severe economic losses. Strategies solving this dilemma by considering interrelation between the spread of the virus and economic activities are in urgent needs for mitigating the health and economic damage. Here we propose an abstract agent-based model for the outbreak of COVID-19 in which economic activities are taken into account. The computational simulation of the model recapitulated the trade-off between health and economic damage associated with lockdown measures. Based on the simulation results, we discuss how macroscopic dynamics of infection and economy emerge from the individuals' behaviours. We believe our model can serve as a platform for discussing solutions to the abovementioned dilemma.

Pattern engineering of living bacterial colonies using meniscus-driven fluidic channels

Engineering spatially organized biofilms for creating adaptive and sustainable biomaterials is a forthcoming mission of synthetic biology. Existing technologies of patterning biofilm materials suffer limitations associated with the high technical barrier and the requirements of special equipment. Here we present controlled meniscus-driven fluidics, MeniFluidics; an easily implementable technique for patterning living bacterial populations. We demonstrate multiscale patterning of living-colony and biofilm formation with submillimetre resolution. Relying on fast bacterial spreading in liquid channels, MeniFluidics allows controlled anisotropic bacterial colonies expansion both in space and time. The technique has also been applied for studying collective phenomena in confined bacterial swarming and organizing different fluorescently labelled Bacillus subtilis strains into a converged pattern. We believe that the robustness and low technical barrier of MeniFluidics offer a tool for developing living functional materials, bioengineering and bio-art, and adding to fundamental research of microbial interactions.
