A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240180 , discusses high-frequency enhanced ultrafast compressed photography technology.
A research team led by Professor Hajime Monzen and Dr. Hiroyuki Kosaka from the Department of Medical Physics at Kindai University has developed the world's first non-contact system for monitoring respiratory motion during X-ray and CT imaging procedures. This breakthrough technology, developed in collaboration with SMK Corporation, uses millimeter-wave sensors to precisely track patient breathing patterns without physical contact, offering a significant advancement in medical imaging accuracy.
Addressing the longstanding challenges of multi-mode fiber (MMF) transmission, the research team led by Prof. Qiming Zhang and Associate Prof. Haoyi Yu from the School of Artificial Intelligence Science and Technology (SAIST) at the University of Shanghai for Science and Technology (USST) has introduced a groundbreaking solution. The team successfully integrated miniaturized multilayer optical diffractive neural networks (DN2s) onto the distal end of MMFs, enabling full-optical image transmission. Regarded as an ONN, the free-space diffractive neural networks (DN2s), have been proposed as more efficient ANN approaches based on deep learning to directly process the optical matrix multiplication at the speed of light, and realizing the high number of connectivity in ANNs, such as optical image classification, decryption and phase detection.
In an article featured in Science China Earth Sciences, researchers from Tianjin University elucidate the coupling relationship between soil fungi and reactive minerals in ecosystems by utilizing global fungal carbon stocks, mineral-associated carbon stocks, and high-resolution nanoscale secondary ion mass spectrometry. They also reveal the mechanisms of fungal-nanoparticle interactions belowground. These findings provide new insights into the critical role of microorganisms in soil carbon stability and storage.
