Historical changes in the distribution of the Sichuan golden snub‐nosed monkey (Rhinopithecus roxellana) in Sichuan Province, China

Ecology and Evolution, Volume 14, Issue 4, April 2024.
Historical changes in the distribution of the Sichuan golden snub‐nosed monkey were identified. Between 1980 and 2000, there was a sharp decline in the distribution area of the Sichuan golden snub‐nosed monkey. The boundary of the distribution area for the Sichuan golden snub‐nosed monkeys in Sichuan Province has significantly shifted northward ...

Effect of Bidirectional Ground Motion on the Response of Double Concave Friction Pendulum Systems

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Recent destructions of structures due to insufficient isolator deformation capacity have led to demands for greater seismic redundancy in seismic isolation design. For a friction pendulum system (FPS), the effect of bidirectional behavior of earthquakes on the maximum response and its effect on friction heating, temperature, and in turn on the maximum ...

Construction of Knowledge Graph for Emergency Resources

International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.
Knowledge graphs can effectively organize and represent information related to emergency resources for unforeseen sudden events. In this study, we construct a model layer for the knowledge graph of emergency resources, focused on sudden events, through the classification and analysis of unforeseen disaster measures.

Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges

, 2020
Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,
