Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

How Aligned Are Citizen Preferences With the 15‐Minute Cities Paradigm? An International Survey and K‐Means Clustering Study

Sustainable Development, EarlyView.
ABSTRACT This study investigates how citizens' mobility preferences align with the principles of the 15‐Minute City (15mC), addressing three research questions: what access times and transport modes citizens consider acceptable, whether mobility preference can be clustered, and which services are perceived incompatible with the 15mC.
