    Exploring the evolution of structure growth in the universe with field-fluid interactions through dynamical stability analysis by Anirban Chatterjee, Abhijit Bandyopadhyay, Debasish Majumdar

    Published 2025-02-01
    “…The coupling parameter $$\alpha $$ α and the parameter $$\lambda $$ λ involved in quintessence potential $$V(\phi ) = V_0e^{-\lambda \kappa \phi }$$ V ( ϕ ) = V 0 e - λ κ ϕ , play crucial roles in governing the dynamics of evolution examined within the present framework. The cosmic evolution, within this context, is depicted as a first-order autonomous system of equations involving appropriately chosen dynamical variables. …”

    Evolution laws and control technology of near and far stress field in hard roof mining roadway by Jie HE, Peng CHENG, Le WU, JunPing FAN

    Published 2024-12-01
    “…In response to the challenge of controlling deformation and damage in hard roof strong mining roadways, the study, taking the 15119 return airway of Sijiazhuang as an engineering background, employs a comprehensive research methodology combining theoretical analysis, field measurements, numerical simulations, and industrial experiments to investigate the evolution patterns of stress fields in hard roof mining roadways at various distances and the corresponding control techniques.Research indicates that when a 25-meter coal pillar is retained in the mining area of 15119 Hui Feng Lane, the difficulty in collapsing the hard roof causes stress concentration at a distance. …”
