In response to the current insufficient in research on dynamic similarity of piles in centrifuge model tests, vertical dynamic similarity conditions through analytical modeling of pile-soil dynamic interaction is obtained in this study. A design approach for model piles is propos...

How Does Entrepreneurial Alertness Lead to Green Product Innovation in Companies? The Roles of Organizational Unlearning and Diversity Climate

ABSTRACT Green product innovation is crucial for achieving a competitive edge during the transition toward carbon neutrality. Existing studies have extensively emphasized the roles of environmental regulations, customer demand, and leadership; however, the importance of entrepren...

Heterogeneous Treatment Effect Estimation with Distribution Shift and Unmeasured Confounding

Heterogeneous treatment effect (HTE) estimation is vital for understanding how treatment effects vary across individuals or subgroups. Recently, numerous HTE models, such as balancing methods and instrumental variable (IV) methods, have been developed to eliminate confounding bia...

Distinct drivers control trace metal distributions through the Atlantic Ocean

Trace metals (TMs) including iron, manganese, cobalt, nickel, copper, zinc, cadmium, and lead have important biogeochemical roles in the ocean. However, the controlling factors of TM distributions have not yet been quantified and investigated on an ocean scale. Here we take a hol...

Three-dimensional information extraction method of wire end for live-line working robots in strong illumination environments

Live-line working robots require the 3D information of wire ends to implement grasping and connection tasks, whereas overexposed images and incomplete point clouds under strong illumination degrade extraction accuracy severely. In this paper, field-collected images and point clou...

Remote‐Controlled Genetic Circuits: Light, Ultrasound, and Magnetic Fields for Programmable Gene Regulation

Remote-controlled genetic circuits use externally applied physical signals to regulate gene expression and cellular functions with spatial and temporal precision. Light, ultrasound, and magnetic fields provide complementary advantages in controllability, tissue accessibility, and...

Unlocking low overpotential and fast reaction kinetics for high-performance Li-CO2 batteries via single-atom-tailored MoN2

Li-CO 2 batteries suffer from high overpotential and sluggish kinetics, calling for efficient cathode catalysts to enhance their charge-discharge performance. Transition metal nitrides have attracted wide attention owing to their high conductivity, good mechanical strength and ex...

Divergent behavior of leachate pollutants in China: Insights from a national database and long-term monitoring

Despite the significant spatial heterogeneity of leachate quality across municipal solid waste (MSW) landfills in China, the underlying mechanisms and potential divergent behavior among different pollutants remain poorly understood. To address this gap, a national leachate qualit...

Blockchain-enabled construction contract administration for extension of time claims: a practice-aligned framework and system

Purpose Existing digital solutions for construction contract administration (CCA) inadequately reflect the complexity and contractual logic of established contract forms. This study addresses this gap by developing a permissioned blockchain-based system – ChainedEOTClaim – for ma...

A Peripheral Sulfonium Moiety Engineering Strategy to Enhance AIEgen-Based Antitumor Photodynamic Therapy

Abstract The therapeutic efficacy of photosensitizers (PSs) strongly depends on their capacity to efficiently generate reactive oxygen species (ROS). Herein, we report a peripheral sulfonium moiety engineering strategy and identify a lead aggregation-induced emission (AIE)-based...

A Social Network Analysis of the Structure and Leadership Roles of a Drug Trafficking Group in China: A Case Study

Despite the proliferation of social network analysis (SNA) in criminological research, our understanding of criminal leadership remains heavily skewed toward Western organized crime group models. This study contributes a descriptive case study of an underrepresented context by ex...

Machine Learning-Assisted Key Toxicant Identification from Mass Spectra: A Case Study of AhR Agonists in Polypropylene Face Masks

Abstract Identifying key toxicants that drive biological effects in complex samples remains a major challenge for environmental analytical chemistry. Here, we developed an AhR-oriented machine-learning model, EIMSFrag-AhR, to predict AhR agonistic activity directly from GC-EI-MS...

Chiral Solid-State Nanopores Amplify Secondary Interactions for Ionic-Current Discrimination of Neurotransmitter Enantiomers

Abstract Single-molecule ionic-current sensing provides a powerful electroanalytical route for resolving small-molecule enantiomers, yet reliable discrimination remains difficult when stereochemical differences generate only weak and transient interfacial interactions. Here, we e...

The dynamic relationship between inclusive leadership, job crafting towards strengths and employees’ career calling: the moderating role of core self-evaluation

Purpose Drawing on the Work as Calling Theory (WCT), we developed and tested a longitudinal model of how employees’ career calling develops over time. Specifically, we examined the dynamic relationships among job crafting towards strengths (JCS), inclusive leadership, and career...

Quasi-zero stiffness TPU interlayer for aluminium–polymer pipe-in-pipe systems: design, modeling and multifunctional performance

An architected thermoplastic polyurethane (TPU) interlayer is proposed for aluminium pipe-in-pipe (PIP) systems to combine load-bearing capacity with vibration attenuation. The interlayer is designed to exhibit a quasi-zero stiffness (QZS) response through geometric deformation....
