Light‐Initiated Tissue Adhesives: Photoinitiation Mechanisms, Material Design Strategies, and Tissue Repair Applications

ABSTRACT Conventional mechanical closure remains widely used in tissue repair, but sutures and staples inevitably cause penetration injury and local stress concentration, limiting their effectiveness in fragile tissues and minimally invasive procedures. Tissue adhesives offer atr...

Space‐Based Observation of Decadal Variations of Ammonium Sulfate Aerosols Over Northern China

Abstract The concentrations of ammonium sulfate, an important component of secondary inorganic aerosols, have dropped substantially in the North China Plain (NCP) over the past decade. However, current understanding of its variations is limited by the small number of ground‐based...

Nonlinear river distance effects on housing prices: Integrating XGBoost and GeoShapley for spatially explicit valuation

Urban river landscapes not only provide recreational and aesthetic benefits but also generate tangible market value. Quantifying the externalities of such amenities on housing prices is critical for evidence-based policy making and spatial planning. Focusing on Tianjin's six cent...

Differences in user attention to interface information of smart fitness applications under certain exercise contexts

By integrating technological advancements into home-based fitness environments, smart fitness applications have increasingly become an integral part of daily exercise routines. A key challenge in their design lies in presenting information that aligns with users’ cognitive and pe...

An improved SCF‑SWE relationship function with topographic controls for enhanced snowmelt runoff simulation

Study region The Yarlung Zangbo River Basin (YZRB), a representative high‑altitude alpine‑glacial basin in Xizang, southwestern China. Study focus To improve the snowmelt runoff simulation accuracy of the EasyDHM (Easy Distributed Hydrological Model) in the YZRB, this study propo...

Identification of flood routing characteristics and vulnerability in complex river networks

To investigate flood routing mechanisms in the Northern Branch of the Daqing River Basin, this study constructed a coupled 1D-2D hydrodynamic model incorporating geospatial datasets and historical flood records. The model performance was validated against remote sensing-derived i...

A hybrid deep learning approach for interpretable inference of potential accidents from hazard reports in hydropower engineering construction

Hazard reports provide early evidence of unsafe conditions and behaviours in hydropower construction, but their potential for proactive accident prevention is often constrained by unstructured narratives and reliance on manual interpretation. Using 9,606 Chinese-language hazard r...

Monotonicity-constrained transfer learning for predicting residual tensile strength of GFRP under wind–sand erosion

Accurate prediction of residual mechanical properties in fiber-reinforced polymer (FRP) composites under harsh environmental conditions is crucial for ensuring structural durability and service safety. This study proposes a monotonicity-constrained transfer learning ResNet (TL-Re...

High-Performance Multilevel Memory Crossbar Array Based on Two-Dimensional Imine Polymer Film with Tunable Memory Behavior

Abstract Multi-state memristors offer great promise for overcoming Moore’s law limitations and effectively increasing information storage density due to the exponential increase in the data storage density from 2n to 3n or even higher (where n is the number of devices in the stor...

Rapid spontaneous generation of organosulfur from inorganic sulfur in atmospheric microdroplets

Abstract Organosulfur compounds are important constituents of atmospheric aerosols and have been extensively investigated through field observations, laboratory experiments, and atmospheric modeling. However, the mechanisms underlying their formation and atmospheric abundance rem...

Construction of the $$a_4$$ family

Abstract The COMPASS Collaboration recently reported a new broad $$J^{PC}=4^{++}$$ J PC = 4 + + structure, denoted as $$a_4(2610)$$ a 4 ( 2610 ) , which has sparked our interest in studying the $$a_4$$ a 4 family with $$I^GJ^{PC}=1^{-}4^{++}$$ I G J PC = 1 - 4 + + . In this work,...

Scalarization of charged Taub–NUT black hole and the entropy bound

Abstract We investigate the spontaneous scalarization of charged Taub–NUT black holes within the framework of Einstein–Maxwell-scalar-Gauss–Bonnet gravity. By selecting a suitable coupling function, the theory admits the analytic charged Taub–NUT geometry as a solution. We demons...

Plasma Characteristics in Underwater Laser Welding via In Situ Observation and Optical Emission Spectroscopy

During underwater laser welding, the coupling among water cooling, gas–liquid interface disturbances, and metal-vapor recoil pressure means that the relationships among plasma evolution, the thermal state of the keyhole, and spatter behavior remain insufficiently understood. In t...
