The Fucheng-1 (FC-1) satellite has successfully transitioned from its initial operational phase and is now undergoing a detailed performance assessment for time-series deformation monitoring. This study evaluates the surface deformation monitoring capabilities of the newly launched FC-1 satellite using the interferometric synthetic aperture radar (InSAR) technique, particularly in urban applications. By analyzing the observation data from 20 FC-1 scenes and 20 Sentinel-1 scenes, deformation velocity maps of a university in Mianyang city were obtained using persistent scatterer interferometry (PSI) and distributed scatterer interferometry (DSI) techniques.

High Absorption and Elasticity of a Novel Transgenic Silk with Egg Case Silk Protein from .

Int J Mol Sci

November 2024

College of Sericulture, Textile and Biomass Science, Southwest University, Chongqing 400715, China.

Spider silk is part of a special class of natural protein fibers that have high strength and toughness: these materials have excellent comprehensive properties that are not found in other natural fibers (including silk) or most synthetic fibers. Spider egg case filaments have good hardness, can resist water, can protect spider eggs from external threats, have a significantly high initial modulus and high moisture absorption rate, and are expected to be used as a new generation of environmentally friendly natural polymer fibers and biomaterials. However, spiders are predatory and difficult to rear in large numbers, and it is also difficult to obtain spider egg case filaments in large quantities.

December 2024

Faculty of Health and Wellness, City University of Macau, Macao, China.

Although humans have been exploring the mysteries of anxiety, relatively few specific cognitive pathways for generation of anxiety have been explored. We integrated many existing theories and experiences in clinical counseling to propose a new anxiety cognitive domino model of anxiety. The model suggests that there are six ordered cognitive factors that affect anxiety, which act like a domino effect, leading to the development and circulation of anxiety.
