Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

Deep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

The world's oldest man‐made biological experiment

Ecography, EarlyView.
Biological experiments are often short‐lived due to logistical or resource‐related challenges, and short‐term observations are extrapolated to make long‐term predictions. However, the effects of experimental treatments on biological communities and processes take time to develop.

The stability of microbial community enhanced in the rhizosphere of Phragmites australis at the regional scale across typical plain and plateau in China

Ecography, EarlyView.
Theoretical and empirical evidence indicates that biodiversity, species coexistence, and community stability are interconnected; however, the mechanisms underlying these associations remain poorly understood, particularly in aquatic ecosystems mediated by macrophytes. Here, we conducted a comprehensive investigation of microbial communities in bulk and

Tree species diversity increases the temporal stability of multitrophic forest beetle communities

Ecography, EarlyView.
As key members of the terrestrial food webs and vital contributors to wood decomposition, beetles play essential roles in ecosystem services but are experiencing widespread declines under climate change. While protecting and restoring forests with high tree species diversity is widely acknowledged as a nature‐based solution for climate change ...

Tsunami Casualty Risk Assessment Integrating Evacuation Tower Placement, Seismic Road Network Performance Enhancement, and Disaster Education

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Since the 2011 Great East Japan earthquake, tsunami evacuation towers have been constructed in coastal regions based on worst‐case predictions to provide additional safety margins against unprecedented tsunamis. However, the extent to which such assumptions effectively reduce casualty risk remains unclear.

A New Classification Method of Surrounding Rock Quality for Phyllite Tunnels Under the Condition of Layer Orientation Parallel to the Orientation of Tunnel Axis

Energy Science &Engineering, EarlyView.
Modified Mass Classification of Layered Rock Masses Based on the HC Method. ABSTRACT The HC method for hydropower is a commonly used rock mass quality classification technique in China's hydropower industry. Due to the anisotropic nature of the layered schist in the study area, and the varying angles between different tunnel layers and the tunnel axis,

Research on the Evolution Law of the Plastic Zone and Control Technologies for Surrounding Rock in Floor Roadway Influenced by Mining Activities

Energy Science &Engineering, EarlyView.
ABSTRACT This study addresses the challenges of deformation failure and the difficulty in controlling the surrounding rock in the 2453 floor roadway of a coal mine in Hunan Province, influenced by mining activities. Conducting an in‐depth investigation into the evolution law of the principal stress and stability control technologies for the surrounding

Estimation of the GCV of Coal Using Real‐Time Plant Data

Energy Science &Engineering, EarlyView.
ABSTRACT Online or real‐time strategies of estimating the gross calorific value (GCV) of coal are still not fully explored in academic literature, even though both conventional and sophisticated offline methods for estimating the GCV are well described.

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...
