The fluoride channel genes crcB1 and crcB2 contribute to high-level fluoride resistance and virulence in Staphylococcus aureus

Staphylococcus aureus ( S. aureus ) can colonize the oral cavity and cause infections ranging from localized disease to systemic illness. Fluoride is widely used in oral care for caries prevention and can inhibit many oral microorganisms. However, S. aureus exhibits high-level fl...

DGFRNet: Dual-guided feature refinement network for forest fire detection near transmission lines

Forest fire detection is crucial for protecting high-voltage transmission lines, yet the coexistence of dense smoke and small flames presents significant challenges for accurate localization and efficient inference. To address this, we propose a framework named dual-guided featur...

Development of a mixture of experts with optimized EfficientNet features (MoEffNet)-powered automated identification system for images of agricultural equipment

Visual data can be used to identify agricultural machines automatically, which is needed to facilitate precision farming, asset management, and autonomous fleet management. Nevertheless, agricultural real-world imagery poses some serious problems because of great intra-class vari...

Comparative effectiveness and safety of robotic versus laparoscopic liver resection for benign liver diseases: a systematic review and meta-analysis

Robotic liver resection (RLR) is increasingly used as an alternative to laparoscopic liver resection (LLR), but its comparative effectiveness and safety for benign liver diseases remain uncertain. We performed a systematic review and meta-analysis to compare perioperative outcome...

Structure–Property Relationships in Mg-MOFs: Dimensional Effects on the Electrocatalytic Detection of Dopamine

Abstract The well-defined crystalline structures of metal–organic frameworks (MOFs) offer a versatile platform for investigating structure–property relationships in electrocatalysis. Herein, we report the synthesis of two magnesium-based MOFs (Mg-MOFs, MOF-1 and MOF-2) constructe...

BiGCNG: Bi-Path Graph Convolutional Neural Network with Gate Fusion for Person–Job Fit

Person–Job Fit (PJF) serves as a core task of intelligent recruitment recommendation. However, existing graph-based PJF models rely on a fixed, single-path aggregation scheme, thereby failing to simultaneously capture global interaction statistics and local competency-matching si...

Construction of composite biological soil crusts accelerates early-stage soil restoration in karst rocky desertification areas

Karst rocky desertification (KRD) represents one of the most severe forms of land degradation globally. Soils in these regions are characterized by structural instability, severe nutrient depletion, and fragmented microbial networks, all of which collectively impose formidable co...

Cannabis sativa L. juice as a novel functional drink ameliorates hyperlipidemia by inhibiting lipid synthesis and oxidative stress

Hyperlipidemia is a major public health concern due to its increasing global prevalence. Hemp seed ( Cannabis sativa L. seed) is a medicinal plant that has gained attention for its potential applications under the “homology of medicine and food” framework. Previous studies sugges...

Investigating the impact of learning modes and instructional sequences of VR-integrated station activities on science learning from the multimodal perspective

Abstract This study explores the impact of different VR learning modes (direct vs. vicarious) and instructional sequences (VR-Reading vs. Reading-VR) on middle school students’ science learning outcomes and transmodal moments during VR-integrated station activities. Using a mixed...

Non-coding RNA 7SK drives tumor resistance by coupling local oncogenic activation with global transcriptional repression

The conserved non-coding RNA 7SK is a well-established global transcriptional repressor, yet its context-specific functions in cancer and therapy resistance remain paradoxical. Here, we resolve this paradox by uncovering a dual-axis mechanism through which 7SK drives colorectal c...

Exploring the Pathways of Green Development Behavior in Building Materials Enterprises Within an Individual–Organizational–Institutional Framework

The green transformation of enterprises is facing major challenges. However, how individual, organizational, and institutional factors jointly shape enterprise green development behavior remains insufficiently understood. This study constructs a three-dimensional analytical frame...

Copper-Based Bimetallic Catalysts for CO2 Hydrogenation to Methanol: Interfacial Synergy, Reaction Pathways, and Rational Design

CO2 hydrogenation to methanol is a key route for carbon recycling within the carbon capture, utilization, and storage (CCUS) framework. Cu-based catalysts are widely employed because of their low cost and high methanol selectivity, yet monometallic Cu suffers from sintering, limi...

Postcranial osteology of the giant oviraptorosaur Gigantoraptor erlianensis

Gigantoraptor erlianensis is an unexpectedly large-bodied oviraptorosaurian dinosaur from the Late Cretaceous of Inner Mongolia, China. Exhibiting a bizarre body plan, G. erlianensis is key to revealing the high morphological disparity and complex evolutionary history near the tr...

Is the accretion flow magnetically arrested in M87?

Abstract It is still debating on whether the disc is magnetically arrested in M87. We assume that a weak external magnetic field is dragged inwards by the accretion disc, which is substantially enhanced to drive strong jets near the black hole horizon via Blandford-Znajek mechani...

A dimeric mRNA vaccine based on key-mutant and KP.3 RBDs induces broad-spectrum immunity and protects mice against JN.1 and XDV challenges

The continued antigenic evolution of SARS-CoV-2 Omicron subvariants has progressively eroded vaccine-elicited protective immunity, driving demand for next-generation candidates that confer broad-spectrum protection against phylogenetically divergent strains. Here we report the de...

Correlation analysis between Helicobacter pylori antibody typing and endoscopic classification of chronic atrophic gastritis and OLGA/OLGIM staging

Abstract Background and aim : Chronic atrophic gastritis (CAG) is a well-established precancerous condition in the gastric carcinogenesis cascade. Helicobacter pylori (Hp) infection is the primary etiological factor for CAG; however, the differential impact of Hp virulence types...

Opposing effects of shared and unshared networks drive species coexistence in intransitive competitive ecosystems

Understanding the mechanisms of species coexistence in intransitive competitive communities, which is generally considered favorable for promoting biodiversity maintenance, has long been a crucial issue in ecology. The role of species dispersal along different pathways in shaping...

Exploring baryon semileptonic decays through polarization and entanglement

Abstract The unitarity of the Cabibbo–Kobayashi–Maskawa (CKM) matrix is a cornerstone of the standard model (SM). Precise tests of this unitarity require independent determinations of its elements, such as | V us |, which governs the transition between strange and up quarks. Curr...

Multiscale Analysis of Depositional Architecture and Diagenetic Evolution in the Cretaceous Shoreface‐to‐Shelf Sandstones, Lower Indus Basin, Pakistan

ABSTRACT Understanding reservoir heterogeneity in siliciclastic systems requires integrated analysis across multiple scales. This study investigates the Early Cretaceous Lower Goru Formation in the Lower Indus Basin using a multiscale integrated approach that combines seismic str...

Development at borderlands: agricultural policy and local practice in Southwest China

Development in China’s border ethnic regions has been driven by strong state intervention, yet existing scholarship often overemphasizes state dominance while overlooking grassroots agency. This dissertation examines how development is enacted and negotiated in everyday agricultu...
