Innovative devices created by the "sociology of electronics"

Professor Hidenori Takagi

It was nearly 60 years ago that the transistor, which underpins modern society, was created through basic research at Bell Laboratories in the United States. As the limits of the semiconductor-based transistor are being called into question, basic research in materials science is being watched with a complex mixture of eager anticipation for "the transistor dream to come true again" and resignation that "the basics are the basics. Under such circumstances, I would like to talk about the concept of correlated electron devices, the innovative electrics (candidate) that basic research is sending out, as "the sociology of correlated electrons.

Smell, pheromones, brain, space.

Associate Professor Kazushige Touharu

Organisms can accurately identify themselves and other individuals by smell, and they also use pheromones to recognize the opposite sex and mate in order to preserve the species. They also use smell as a cue to find food. We will introduce the mechanism of olfaction, a sensory organ that helps us understand the external environment, and examine the instinctive, evolutionary, and ecological "smell landscape" that exists around living things.

Structural safety of social infrastructure

Professor Jun Kanda

The structural design of civil engineering and building structures has been developed based on allowable stress design, which is based on empirical resistance to the Kanto Earthquake and Muroto Typhoon, and is the basis for legal standards. The limit state design method, which uses reliability indices as the measure of safety, is recognized internationally, and the discussion of safety accepted by society should be based on reliability indices. In this context, probabilistic hazard assessment of seismic motion and strong wind is important. The life cycle assessment of a structure can be made more accountable to society by obtaining the minimum value of the sum of the initial cost and the expected loss cost during the service period, which is determined according to the safety. For practical use, we are proposing load factors and disclosing a probabilistic safety assessment tool to society.
