Mechanical properties and fracture failure characteristics of fractured limestone under coupled freeze-thaw and cyclic loading

<title>Abstract</title> The Central Asian Orogenic Belt possesses abundant mineral resources. As mining activities extend into high-altitude cold regions, the safety and stability of rock engineering projects, such as open-pit mine slopes, have become increasingly prominent. This...

Spatiotemporal distribution of precipitation microphysical characteristics over the Tianshan Mountains based on GPM/DPR observations

Using monthly mean Level-3 GPM/DPR products from March 2014 to February 2023, this study systematically investigates the spatial distribution, vertical structure, and microphysical characteristics of stratiform and convective precipitation over the Tianshan Mountains. The results...

Emergent MOND from Cosmological Horizon Thermodynamics: Unruh-Hawking Resonance and the Redshift Evolution of the Critical Acceleration

The empirical success of Modified Newtonian Dynamics (MOND) contrasts sharply with its lack of a fundamental microscopic mechanism. We propose a radical conceptual breakthrough: the MOND critical acceleration a₀ is not a fundamental constant, but a macroscopic emergent phenomenon...
