Enhancing Seismic Safety, Satellite Navigation Precision, and Data Storage Innovations

A study in Pakistan highlighted the seismic vulnerability of non-engineered structures in Dir City, emphasizing the need for stricter regulations and retrofitting. In satellite navigation, a new method integrating inter-satellite link data with onboard observations significantly improves orbit determination precision. Additionally, a LEGO-like hydrogel system developed in Beijing enables reversible 3D information encoding, offering dynamic data storage and manipulation capabilities.
