Review and Integrated Framework for Deep‐Sea Mineral Resources, Ecological Influence, and Future Development

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
As global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

Structural Response Reconstruction Based on Experimental Approximation and Model Reduction

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Model‐driven response reconstruction is widely applied to supplement inaccessible dynamic information in mechanical structural health monitoring. However, increasing complexity of structures with considerable degrees of freedom and nonshareability of substructures based on security issues make it inefficient, even impossible, to perform response ...
