Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Development and Validation of a Seismic Design Method for Anchored Retaining Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Study on Roof‐Control Technology for Gob‐Side Entry Retaining Under Composite Roofs

Energy Science &Engineering, EarlyView.
This study develops a roof‐control technology system for gob‐side entry retaining under composite roofs. By integrating field measurements, theoretical analysis, and numerical simulation, it reveals the spatiotemporal evolution of the plastic zone and proposes a targeted support method, providing theoretical and practical guidance for safe and ...

CD8+ T‐cells, CD86+ macrophages and TNF‐α signalling pathways are correlated with fetlock osteoarthritis in racehorses

Equine Veterinary Journal, EarlyView.
Abstract Background There is emerging evidence for the role of the immune system in osteoarthritis (OA) pathophysiology; however, little is known about how immune cells and the synovial transcriptome are altered in naturally occurring equine OA. Objectives To evaluate synovial fluid (SF) and synovial membrane (SM) immune cell populations and the SM ...

Bending Fatigue Evaluation and Failure Modes of Ultra‐Thin Silicon Chips on Flexible Substrates

FlexTech, EarlyView.
This study investigates the fatigue lifetime of 20‐μm‐thick chips under bending deformation. Three failure modes are identified: metal pad wearing, metal stress migration, and gold wire break. The underlying mechanisms are analyzed through micro‐scale characterization, and temperature effects on fatigue lifetime are explored.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...
