The Boltzmann distribution in statistical mechanics has a form mathematically equivalent to Bayesian statistics. Using this equivalence, many problems described based on Bayesian statistics, such as information theory, communication theory, learning theory and constraint satisfaction problems in computer science, can be described by spin systems. In this talk, starting with the Hopfield model, which is a spin model introduced as a model of memory, I will show how error correcting codes in information theory can be described by spin systems, and suggest that statistical mechanics can be one of the starting points for academic integration.

Metagenomic analysis is a method to analyze the genome of the entire microbial population (flora) in the environment. Metagenomic analysis is a method to analyze the genome of an entire microbial population (flora) in the environment. This method has enabled us to obtain genetic information on the mostly difficult-to-cultivate bacterial species and to elucidate the ecological functions of the entire flora, including interactions with the environment. In this seminar, we will introduce the findings obtained from the metagenomic analysis of the intestinal microflora consisting of approximately 1000 bacterial species that are closely related to human health and disease.

We have developed a microdroplet generation method in microchannel and applied it to various droplet and polymer particle generation methods. Until now, there has been no method for generating monodisperse microparticles with a size larger than 10 mm, but our method allows the particle size to be freely varied. In addition, it is possible to precisely control the size and number of droplets in a multiphase emulsion. This method is attracting attention from companies because it can provide a manufacturing technology that was not possible before.
