Researchers at the University of Electro-Communications have introduced an innovative approach to improving system security. The new framework uses advanced techniques to analyze business process logs and ensure that role-based access rules are properly followed. By combining specialized languages and intelligent analysis tools, it can uncover potential security risks and help organizations address them effectively. Tested on real and simulated systems, this flexible and scalable approach provides a powerful way for organizations to improve security and protect sensitive data.
A research team at Yokohama National University has developed a way to study how the orientation and behavior of electrons in titanium influence its physical characteristics. Their findings, published in Communications Physics on December 18, 2024, could pave the way for the development of more advanced and efficient titanium alloys.
There have been dramatic advances in the natural sciences thanks to inventions such as telescopes and microscopes that enable us to see things invisible to the naked eye. The arrival of X-ray photography, CT (computed tomography), and MRI (magnetic resonance imaging) has transformed healthcare, and the pioneers of CT and MRI both received Nobel Prizes. Professor KIMURA Kenjiro has developed a technology that can produce 3D images of the inner structure of an object by applying waves (for example, radio waves) to the object and measuring the wave scattering.
He has recently drawn attention for advances in microwave mammography technology, a system that revolutionizes breast cancer screenings by visualizing the cancer to a high level of accuracy using very faint microwaves. He has also used magnetic fields to develop a system that visualizes abnormal electric currents in lithium-ion rechargeable batteries and the memory of advanced semiconductors. With research that pursues the science of visualization and a startup to ensure that their findings can benefit society at large, Kimura and his team are contributing to the health and security of humanity.
Mathematicians at the Okinawa Institute of Science and Technology (OIST) are developing a new approach to detect cancer early. This technique could provide a powerful new tool against the disease and involves solving partial differential equations (PDEs).
Prof. Ugur Abdulla, head of the Analysis and Partial Differential Equations Unit, joined OIST with the goal of making it one of the world’s leading centers in mathematics. "We want OIST to be a key place for sharing math knowledge globally," he said. "Our work with partner institutes helps us connect with different parts of the world, sharing knowledge and providing opportunities for PhD students to work on cutting edge problems in the frontline of mathematics."
A recent study by researchers at Institute of Science Tokyo reveals the pivotal role of tristetraprolin (TTP), an RNA-binding protein, in regulating inflammatory responses in basophils, immune cells central to allergic reactions. The research shows that TTP controls the stability of mRNAs for inflammatory molecules, preventing their overproduction. Using TTP-deficient mice, the team found heightened allergic inflammation, suggesting TTP as a promising therapeutic target for treating allergic and inflammatory diseases.
