How to ensure high-quality synthetic wireless data when real-world data runs dry
To train artificial intelligence (AI) models, researchers need good data and lots of it. However, most real-world data has already been used, leading scientists to generate synthetic data. While the generated data helps solve the issue of quantity, it may not always have good quality, and assessing its quality has... Read more

Advanced broadband optical signal filtering developed with chirped and tilted fiber Bragg grating
Optical signal transmission can be significantly improved by limiting the wavelength of transmitted signals. Fiber Bragg grating (FBG) is a technique widely used in optical communication, sensing, and laser technologies for selectively blocking certain wavelengths of light. In optical fibers, FBG functions as a band-rejection filter that reflects specific light... Read more

Matryoshka doll-like robot changes its shape in real time and in situ
Until now, when scientists created magnetic robots, their magnetization profiles were generally fixed, enabling only a specific type of shape programming capability using applied external magnetic fields. Researchers at the Max Planck Institute for Intelligent Systems (MPI-IS) have now proposed a new magnetization reprogramming method that can drastically expand the... Read more
