In recent years, the social situation in cities has changed significantly such as redevelopment due to the massive earthquake and large-scale urban development.For example, numerical simulations can be used to study this Production Editing Controllers phenomenon.Such simulations require the construction of high-definition three-dimensional city mod
Deep-sea anglerfishes are relatively abundant and diverse, but their luminescent bacterial symbionts remain enigmatic.The genomes of two symbiont species have qualities common to vertically transmitted, host-dependent bacteria.However, a number of traits suggest that these symbionts may be environmentally acquired.To determine how anglerfish symbio
