Turing patterns go nano
The formation of certain patterns in nature, such as particular animal skin stripes or spots, can be explained by means of reaction–diffusion theory. This formalism, developed by Alan Turing, is based on the presence of two components (called ‘activator’ and ‘inhibitor’) with different diffusion rates. These two-component situations can give rise to what is collectively known as Turing patterns, such as the stripes seen on the skin of tropical fish or emerging order in chemical systems.
Typical length scales of biological Turing patterns range from millimetres to centimetres. For purely chemical systems, the characteristic lengths are usually sub-millimetre. Although reaction–diffusion theory does not pose limits on intrinsic length scales, Turing patterns on the nanometre scale are rare. Recently, however, Yuki Fuseya from the University of Electro-Communications, Tokyo, and colleagues have identified a new type of nanoscale Turing patterns in a monolayer of bismuth atoms on a substrate.

Impact of the largest Gamma-Ray Burst on the Earth’s ionosphere
Satellites detect gamma-ray bursts most days but rarely do these events affect the ionosphere. However, when they do, they have a measurable impact on the propagation of Low Frequency (LF) and Very Low Frequency (VLF) radio waves there. Now researchers led by Yasuhide Hobara at the University of Electro-Communications have examined the impact of the Gamma-Ray Burst GRB221009A, which took place on 9th October 2022 and is the largest detected gamma-ray burst ever recorded on Earth. They reported their results in the journal Atmosphere on 20th January 2023.

Artificial intelligence for energy, materials science, and quantum computing
Tomah Sogabe, Associate Professor, Faculty of Informatics and Engineering,
Tomah Sogabe’s research focuses on integrating cutting-edge AI techniques into three key research areas: energy optimization, device design, and quantum computing. The primary objective is to create automatic control systems and design schemes that tackle tasks too complex for human knowledge alone.
Hideyuki Nomura, Professor, Graduate School of Informatics and Engineering
Hideyuki Nomura specializes in acoustic electronics. While traditional acoustics research focuses on applications such as speech recognition and media processing for listening purposes, Nomura’s group explores acoustic technology development without the goal of listening. They work across a wide frequency range, from audible to ultrasonic frequencies, to improve our lives.
Researchers unveil avatar “Yui” for teleoperation in real-world environments
Yoshihiro Nakata, Associate Professor, School of Informatics and Engineering, Department of Mechanical and Intelligent Systems Engineering
In a groundbreaking development, researchers unveil an Android Avatar named Yui, designed as a mobile humanoid Cybernetic Avatar (CA). A newly released video showcases the goals of an innovative project on CA and anticipated applications. The project establishes a versatile platform for CAs that can navigate everyday environments via teleoperation, enabling diverse social participation and providing an immersive control interface for operators.

About the University of Electro-Communications
The University of Electro-Communications (UEC) in Tokyo is a small, luminous university at the forefront of pure and applied sciences, engineering, and technology research. Its roots go back to the Technical Institute for Wireless Commutations, which was established in 1918 by the Wireless Association to train so-called wireless engineers in maritime communications in response to the Titanic disaster in 1912. In 1949, the UEC was established as a national university by the Japanese Ministry of Education and moved in 1957 from Meguro to its current Chofu campus Tokyo.
With approximately 4,000 students and 350 faculty members, UEC is regarded as a small university, but with expertise in wireless communications, laser science, robotics, informatics, and material science, to name just a few areas of research.
