Species-specific phenological indicators reveal topographic–climatic associations with evergreen-tree phenology in subtropical hilly regions

Evergreen-tree phenology is an important ecological indicator of forest responses to climate change and local environmental heterogeneity. In subtropical hilly regions, frequent cloudy and rainy conditions, complex terrain, and weak seasonal greenness signals hinder species-level...

Mixed emotions enhance consumer acceptance of distant brand extensions: the role of dialectical thinking as a mediator

Purpose This study aims to examine how mixed emotions (simultaneous happiness and sadness) influence consumer evaluations of distant brand extensions, addressing a critical gap in low-fit extension strategies. Design/methodology/approach Four experimental studies were conducted e...

Process intensification of indigenous algal-bacterial consortia by ARTP-mutagenized Chlorella for aquaculture wastewater treatment and resource recovery

Achieving stable algal-bacterial treatment in real aquaculture wastewater remains difficult because indigenous microbiota are often viewed as uncontrollable background communities rather than functional components with regulatory potential. In this study, atmospheric and room-tem...

Electrical insulation enhancement of the Al 2 O 3 composite films at high temperature by oxygen vacancy suppression

Abstract The electrical insulation film is critical for the reliable operation of Ultra-high temperature thin-film sensors (UTTSs) at elevated temperatures. However, the resistance of the insulation film easily decline at high temperatures due to the formation of the oxygen vacan...

Catalyst-free Polyannulations of Potassium Sulfide and Unactivated Alkynes toward Multifunctional Thiophene-Containing Polymers

Abstract Facile and efficient transformation of inexpensive inorganic sulfides into high-value polymer materials is of great academic and industrial significance. Herein, we report a catalyst-free polyannulation strategy between potassium sulfide and internal diynes, which can ef...

Explainable Transformer-Based Estimation of Surface NO2 Concentrations Across Fujian Province Using TROPOMI Observations

Atmospheric nitrogen dioxide (NO2) is one of the major pollutants affecting environmental quality and human health, yet accurate surface NO2 (NO2Surface) estimation remains challenging due to complex nonlinear relationships between satellite-derived NO2 column density (NO2column)...

Cooperative Agostic‐Type C─H···Cu, Quadrupolar Cu···CO 2 , and C─H···O/π Interactions in an Ultra‐Microporous MOF Enable One‐Step Methane Purification From Quaternary C 3 H 8 /C 2 H 6 /CO 2 /CH 4

ABSTRACT While agostic‐type C─H···metal σ‐interactions are central to organometallic catalysis, their role in gas separation remains elusive. In this study, a robust phosphine‐functionalized ultra‐microporous Cu(I/II)‐organic framework, LIFM‐XYY‐15, featuring open metal sites (OM...

Modeling the Relationship Between Ride-Hailing Demand Density and the Urban Built Environment on the Basis of the GNNWR and Dynamic Spatial Partitioning

Understanding the complex spatiotemporal heterogeneity between ride-hailing demand and the urban built environment is crucial for optimizing urban space and allocating transportation resources. Previous analyses using fixed spatial scales (e.g., regular grids or administrative bo...

Multi-objective optimization of cylinder liner honing surface parameters for lubrication and wear properties based on BPNN–NSGA-II

Simultaneously enhancing oil film thickness while controlling wear load remains a key challenge in cylinder liner honing texture optimization, yet these performance indicators are typically optimized separately. This study proposes a simulation-driven multi-objective framework th...

Acute Reactive Strength Responses and Peak Power–Performance Relationships After Flywheel Calf Raises in National‐Level Track‐and‐Field Athletes: A Randomized Crossover Trial

ABSTRACT This study examined reactive strength responses to flywheel eccentric calf raises performed under three inertial loads and the associations between peak power and post‐intervention reactive strength. Thirty‐seven national‐level male track‐and‐field athletes completed thr...

A boundary-coupled unified frictional hysteresis model for metal rubber under quasi-static and dynamic loading

Metal rubber (MR) contains numerous internal contact, sliding, and frictional interfaces among metallic wires, which leads to pronounced nonlinear and hysteretic characteristics under quasi-static and dynamic loading conditions. Existing hysteresis models are mostly developed for...

Construction of Injectable Hydrogels Based on Cationic Porphyrins and Hyaluronic Acid for Wound Healing With Multimodal Antibacterial Therapy and Instantaneous Monitoring

ABSTRACT Although hydrogels with antimicrobial and monitoring have the potential for precision wound therapy, it is difficult to construct smart framework of hydrogels in molecular level. Herein, an in situ crosslinked antimicrobial conductive hydrogel (Au/HA‐TPP) based on 5,10,1...

Unveiling the Critical Binder Requirements for High-Energy-Density Silicon-Based Pouch Cell

Abstract Silicon is gradually replacing graphite as a novel anode material for high-energy-density lithium-ion batteries. However, the substantial volume changes of silicon during lithiation/delithiation make the anode binder, which maintains electrode structural stability, criti...

Terminal-Assisted Web Authentication for Shared Devices with BLE-Based Confirmation Gating

In shared-device scenarios, terminal-assisted Web authentication reduces credential exposure by keeping authentication credentials on a user-carried mobile terminal. However, existing methods struggle to minimize mobile interaction while protecting against account misuse by other...

Electrical signal transmission across electrolyte junctions separated by atomically-thin graphene

Signal transmission across membranes is usually mediated by the permeation of molecular species. Here we show that atomically thin graphene crystals, although impermeable to any ions or molecules, can transmit interfacial electrical potentials across electrolyte junctions without...

Connected Social Media

Abstract We examine whether and how firms use connected social media outlets to counteract negative coverage in traditional media. Employing a sample of Chinese listed firms with ties to social media outlets, we find that connected outlets portray firms more favorably than unconn...

Depth-dependent response functions and rainfall transition zones of soil-profile activation under varying antecedent moisture in the Shandian River Basin, northern China

Translating event rainfall into soil-profile wetting requires more than recording whether soil moisture increased; it requires estimating how activation response functions change with depth and antecedent moisture. We analyzed 955 rainfall site-events from 20 co-located rainfall...

Metabolomics for Athlete Monitoring: An Evidence-Readiness Framework for Contextual Validation

Metabolomics can place the metabolic consequences of training, competition, recovery, nutrition, and environmental exposure in a physiological context. However, an exercise-responsive metabolite should not be regarded as decision-ready on the basis of a pre–post association alone...

Computational Prediction of Pressure-Responsive Luminescence of a D-π-A Compound with Boron–Nitrogen Motifs

Abstract Under pressure, organic luminescent materials typically display peculiar and fascinating photoluminescence behaviors. Elucidating the luminescence mechanism under pressure is the key to the rational design of piezochromic materials. Here, we carried out an in-depth theor...

SwinTransRNA: A Swin Transformer-Based Framework for Accurate Prediction of RNA Subcellular Localization

Abstract RNA subcellular localization determines the regulatory context in which microRNAs (miRNAs), circular RNAs (circRNAs), and long noncoding RNAs (lncRNAs) exert their functions, yet these RNA classes differ greatly in sequence length and circularity, making fixed-length raw...
