In the developing countries of Asia and Africa, where the population continues to grow, increasing rice production is an urgent issue. new rice cultivation methods have begun to spread in many countries since the beginning of the 21st century, but they have not replaced the old methods. In addition, this farming method is still in its infancy and controversial. However, it is becoming clear that in addition to increasing revenue, it also saves water and reduces GHG (greenhouse gas) emissions. In the seminar, we would like to discuss the potential of this rice farming method.

　Electric vehicles have attracted a great deal of attention for their energy efficiency and environmental performance, and due to the rapid development of battery performance, various companies have begun commercializing them. In addition, from the viewpoint of vehicle motion control, electric vehicles are also very attractive because of their fast torque response, accurate grasp of the generated torque, and the possibility of independent drive of each wheel. In order to pursue the research on the motion control performance of electric vehicles, we have built a completely original electric vehicle equipped with electric active steering mechanisms on the front and rear wheels and high torque direct drive in-wheel motors on the four wheels. In this talk, I will explain various motion control technologies developed in our laboratory using this vehicle, such as traction control, vehicle attitude control, pitching control during emergency braking by force and regenerative torque, and range extension control system, and clarify the advantages of the developed control methods. 　 Recognition of self by innate immune cells

　Our bodies as multicellular organisms are exposed to the dangers of external pathogens and the development of cancer cells in our bodies, but in most cases, our immune systems protect us from these dangers. In many cases, the immune system protects us from these dangers. The immune system needs to discriminate between self and non-self and eliminate the non-self. Until now, research in immunology has focused on elucidating the mechanisms that recognize non-self such as pathogens or abnormal self such as cancer cells, but in addition to these mechanisms, the existence of mechanisms that recognize self and avoid its attack has become clear. In this seminar, we will introduce the mechanisms by which NK cells and dendritic cells, which are responsible for innate immunity, recognize normal self.
