Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability
Deep Underground Science and Engineering, EarlyView.Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Eating disorders (EDs) often emerge in adolescence, but developmental trajectories across different core features remain largely unclear. Method The prospective, community‐based study included N = 898 participants aged 9.5–17.5 years (47.6% female, age 11.8 ± 1.4 years) with annual follow‐up over 2–6 (3.4 ± 1.2) years.

Alpha, beta and gamma diversity in relatively natural, mixed and transformed landscape scenarios
Ecography, EarlyView.Biodiversity losses and biotic homogenisation associated with human‐induced land‐cover changes are key issues for ecology. However, the effects of human‐caused land‐use changes on biodiversity change at the landscape scale are not well understood. Combining the PREDICTS global biodiversity database with MODIS satellite‐based land cover from 2001 to ...

Beam Elements on Linear Variable Two-Parameter Elastic Foundation [PDF]
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2008 The traditional way to overcome the shortcomings of the Winkler foundation model is to incorporate spring coupling by assemblages of mechanical elements such as springs, flexural elements (beams in one-dimension, 1-D, plates in 2-D), shear-only layers ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

ANALYSIS OF THICK RECTANGULAR PLATES RESTING ON NONLINEAR WINKLER FOUNDATION
Journal of Engineering and Sustainable Development, 2016 This research deals with the elastic behavior of thick plates resting on nonlinear Winkler foundation. Mindlin’s thick plate theory is extended to include the effect of nonlinear elastic foundation.

Galerkin Solution of Stochastic Beam Bending on Winkler Foundations
Computer Modeling in Engineering & Sciences, 2010 In this paper, the Askey-Wiener scheme and the Galerkin method are used to obtain approximate solutions to stochastic beam bending on Winkler foundation. The study addresses Euler-Bernoulli beams with uncertainty in the bending stiffness modulus and in the stiffness of the foundation. Uncertainties are represented by parameterized stochastic processes.
