Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

Deep Underground Science and Engineering, EarlyView.
This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Ethnic disparities in health-related quality of life and cognitive function after stroke in the Netherlands

Health and Quality of Life Outcomes
Background/objective European data regarding ethnic disparities in health-related quality of life (HRQOL) post- stroke is scarce and none used the Patient-Reported Outcomes Measurement Information System (PROMIS). This study explores whether ethnicity is

Effect of compressive creep in load transfer components on relaxation behavior of FRP cable extrusion anchorages

Case Studies in Construction Materials
This study investigates 1000-hour and million-hour creep behaviors in load transfer components (LTCs) and evaluates the impact of LTC’s compression creep on fiber-reinforced polymer (FRP) cable extrusion-anchorage relaxation.

Fire‐Safe Polymeric Insulation Foams for Energy‐Efficient and Low‐Carbon Buildings

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review systematically summarizes recent advances in fire‐safe polymeric insulation foams, emphasizing the balance among flame retardancy, thermal insulation, mechanical reliability, and long‐term durability. By linking material‐level thermophysical properties with building cooling‐energy demand and operational carbon emissions, it establishes a ...

A Genetic Algorithm‐Optimized LSTM Framework for Mechanics‐Conditioned Reconstruction of Stress–Strain Curves in High‐Performance Cementitious Materials

Energy Science &Engineering, EarlyView.
GA‐optimized LSTM for full stress–strain curve prediction of high‐performance cementitious materials. Compression‐test data are preprocessed (cleaning, normalization, interpolation/standardization, and Savitzky–Golay smoothing). A Genetic Algorithm tunes LSTM hyperparameters, while a physics‐informed loss enforces stiffness, peak response ( σ max ...

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Vibrational Mode-Specific Dynamics of the OH + XO→ H + XO₂ (X = C/S) Reactions: Similar Topologies, Different Dynamics

Molecules
The prototypical complex-forming reactions of OH + CO and OH + SO are critical elementary processes in atmospheric chemistry and combustion systems. The vibrational mode-specific quasi-classical trajectory (QCT) investigations for these two reactions ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...
