Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

open access: yesDeep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Recursion and subrecursion over finite and infinite words with applications to computable real valued functions

open access: yes, 2007
A recursion scheme for functions on intervals to approximate real-valued functions is described and compared with recursion schemes on finite and infinite words. Es wird ein Rekursionschema für Funktionen auf Intervallen, die reellwertige Funktionen approximieren, beschrieben und mit Rekursionsschemata auf endlichen und unendlichen Wörtern verglichen.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Researching Attitude–Identity Dynamics to Understand Social Conflict and Change

open access: yesEuropean Journal of Social Psychology, EarlyView.
Abstract Societies undergo constant change, manifested in various ways such as technological developments, economic transitions, reorganization of cultural values and beliefs, or changes in social structures. Individuals play an active role in shaping social and societal change by interactively negotiating its manifestation.
