Towards a physics-informed network paradigm with data generation and background noise removal for different distributed acoustic sensing applications

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

A research team from Shanghai Jiao Tong University has developed a physics-informed neural network for distributed acoustic sensing. The approach generates synthetic event data and removes background noise without relying on real-world event data. Demonstrated in public datasets and belt conveyor fault monitoring, the method achieves high accuracy and generalizes across different sites, offering a scalable solution for industrial monitoring and optical sensing applications.

Next-generation chip design empowers autonomous vehicles

Peking University
Reports and Proceedings

Peking University, September 3, 2026: As the auto industry is accelerating toward AI-powered autonomous vehicles (AV), autonomous driving chips are emerging as a key determinant of whether safe, scalable, and commercially viable autonomy can be achieved. In a close examination of how chip design can address these requirements, a joint Peking-Tsinghua research team has proposed, in a Perspective, a cross-layer roadmap for next-generation intelligent chips. The Perspective, titled “Autonomous driving chips,” brought together 59 researchers from more than 20 institutions and was published in Nature Reviews Electrical Engineering.

Latent Seal embeds robust watermarks during image generation to support copyright protection

Maximum Academic Press
Peer-Reviewed Publication

A research team has developed Latent Seal, a watermarking framework that places high-capacity image watermarks inside the generation process of latent diffusion models (LDMs), rather than attaching them after an image is created.

Stricter vehicle standards reveal hidden toxicity in cleaner exhaust

Chinese Society for Environmental Sciences
Peer-Reviewed Publication

Stricter vehicle standards are sharply reducing the total mass of volatile organic compounds (VOCs) released by passenger cars, but they are also changing what remains in the exhaust.

Multiple LEO satellites sharpen BeiDou-3 orbits and speed positioning

Aerospace Information Research Institute, Chinese Academy of Sciences
Peer-Reviewed Publication

A research team from Wuhan University and Beijing Future Navigation Tech Co., Ltd. has shown that a small group of low Earth orbit satellites can make regional satellite-navigation infrastructure work more like a global high-precision network.

New strategy improves power conversion efficiency of TOPCon solar cells

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Scientists from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences have developed a new synergistic metallization strategy for tunnel oxide passivated contact (TOPCon) solar cells. The approach achieved a certified power conversion efficiency (PCE) of 26.31%, among the highest reported for this technology.

Common plant derived chemical may pose overlooked risks to aquatic ecosystems

Shenyang Agricultural University Collaborative Journals
Peer-Reviewed Publication

Pyrogallol is found naturally in plants and can also enter the environment through industrial activities, wastewater, and the breakdown of organic matter. Despite its widespread origins and long history of use, scientists say its potential effects on aquatic ecosystems have received far less attention than those of many synthetic pollutants.

Fishbone-derived catalyst turns agricultural plastic waste into olefin-rich bio-oil

Shenyang Agricultural University Collaborative Journals
Peer-Reviewed Publication

Agricultural plastic mulch helps farmers conserve water, control weeds, and improve crop productivity, but disposing of the used films creates a growing environmental challenge. Researchers have now developed a catalyst made from fishbone-derived char, phosphoric acid, and iron that converts low-density polyethylene agricultural film into bio-oil with a yield of up to 89.32 wt.% and an olefin selectivity of 84.03%.

Returning rice straw helps paddy soils lock away more carbon through iron-mediated protection

Shenyang Agricultural University Collaborative Journals
Peer-Reviewed Publication

Returning crop straw to farmland is widely used to recycle nutrients and improve soil quality. New research now reveals another important benefit: straw return may help paddy soils retain more organic carbon by activating two complementary forms of protection, one physical and one chemical.
