A simulation approach to the stochastic growth of bacterial towers is presented, in which a non-uniform and finite nutrient supply essentially determines the emerging structure through elementary chemotaxis. The method is based on cellular automata and we use simple, microscopic, local rules for bacterial division in nutrient-rich surroundings. Stochastic nutrient diffusion, while not crucial t...

Metal additive manufacturing (AM) technologies are attracting attentions not only as a fabrication process of complicated three-dimensional parts but also microstructure controlling processes. In powder bed fusion (PBF)-type AM, crystallographic texture can be controlled by scanning strategies energy beam. To optimize microstructures, computer simulations for predicting microstructures play ver...

Cellular automata have recently attracted a lot of attention as testbeds to explore the emergence many-body quantum chaos and hydrodynamics. We consider Rule 54 model, one simplest interacting integrable models featuring two species quasiparticles (solitons), in presence an integrability-breaking perturbation that allows solitons backscatter. study onset thermalization diffusive hydrodynamics t...
