Experimental study on the nonlimit active earth pressure of finite soil in proximity engineering.

This study focuses on the active earth pressure distribution of finite soil masses in urban proximity engineering, with a specific emphasis on nonlimit conditions. Through laboratory model tests, the relationship between the nonlimit earth pressure and displacement of the finite soil mass is investigated. Furthermore, the distribution law of the nonlimit earth pressure is explored, considering the influence of the existing structure, proximity distance, and soil cover thickness of the existing structure on the nonlimit earth pressure distribution within the finite soil mass.

Clinical Forms of Japanese Spotted Fever from Case-Series Study, Zigui County, Hubei Province, China, 2021.

We report a case-series study of 5 patients with Japanese spotted fever from the Three Gorges Area in China, including 1 fatal case. Seroprevalence of Rickettsia japonica was ≈21% among the local population. Our report highlights the emerging potential threat to human health of Japanese spotted fever in the area.
