Pyrolysis-Tuned Dual-Function Biochar-Derived Dissolved Organic Matter Drives Redox Coupling for Deep PFAS Defluorination in UV/Sulfite Systems

Abstract The growing use of biochar is increasing the release of biochar-derived dissolved organic matter (BDOM) in surface waters. Concurrently, remediation of persistent per- and polyfluoroalkyl substances (PFAS) remains challenging. Although natural DOM can both photosensitize...

A curious application of identities: a happy accident

Consider a parallelogram ABCD, with points M and N located on the segments BA and BC, respectively. Let I, J and K be the midpoints of the segments DM, MN and DN, respectively. Prove that the lines...

Microenvironment-aware transcriptome reconstruction in spatial transcriptomics

Abstract Imaging-based spatial transcriptomics offers single-cell resolution but measures limited panels dominated by identity-defining genes, leaving transcriptome-wide variation unobserved. Existing approaches for predicting unmeasured genes rely mainly on shared-gene alignment...

Beyond static conservation: social-ecological system resilience insights for Karst World Heritage buffer zone management

Abstract This SALSA-based review of 197 WoS and CNKI articles synthesizes advances and gaps in SESR theory, methods, model construction, empirical demonstration, and benefit evaluation. It examines how resilience thinking may inform a shift from static conservation to adaptive ma...

CIAFNet: An RGB-D Cross-Modal Interaction and Adaptive Fusion Network for Camellia oleifera Fruit Detection

To better address the accuracy bottleneck of RGB-only Camellia oleifera C.Abel fruit detection in complex orchard environments, this paper proposes CIAFNet—a dual-stream RGB-D fusion detection network—and evaluates its potential as a visual front end for relative 3D localization...

MRIo3DS-Net: a mutually reinforcing images to 3D surface RNN-like framework for model-adaptation indoor 3D reconstruction

Currently, deep neural networks (DNNs) have made some progresses in local region feature extraction, image matching under difficult conditions and point cloud surface optimization in photogrammetry and computer vision. However, there have been being no reports on an end-to-end hi...

Evaluation of teachers’ digital literacy combining survey data and digital platform usage data

Teachers’ digital literacy is a crucial component of educational innovation and talent cultivation in the digital age. Traditional evaluations have largely relied on self-reported evidence such as questionnaires and interviews. With the increasing use of educational digital platf...

Constructing Integrative Catalytic Pairs in Carbon Nanohorns for Enhanced Neutral H 2 O 2 Electrosynthesis

ABSTRACT Electrosynthesis of hydrogen peroxide (H 2 O 2 ) via the two‐electron oxygen reduction reaction (2e − ORR) offers a sustainable and decentralized alternative to the anthraquinone process. However, conventional solo‐active‐site catalysts are intrinsically limited by scali...

PML Method for the Stochastic Acoustic Scattering Problem Driven by an Additive Gaussian Noise

Abstract. This paper is concerned with the time-domain stochastic acoustic scattering problem driven by a spatially white additive Gaussian noise. The main contributions of the work are twofold. First, we prove the existence and uniqueness of the pathwise solution to the scatteri...

The relationship between parental mediation and problematic internet use among adolescents: roles of hiding online behaviors and autonomy

Abstract Background In a modern information society, problematic internet use among adolescents poses challenges to family education, and research on the effects of parental mediation has yielded inconsistent findings. To explore the possible pathways underlying these association...

Enantioselective Convergent Synthesis of Heterohelicenes via Copper-Catalyzed Propargylic Annulation/Acid-Promoted Aromatization

Abstract Heterohelicenes combine helical chirality with tunable electronic properties, making them attractive for applications in chiral materials and optoelectronics. However, their enantioselective synthesis, particularly for five-membered heterohelicenes, remains a long-standi...

Iteratively DesignedPhospholipid-Targeted SupramolecularSonosensitizers for Precision Treatment of Pulmonary Infections

Abstract Fungal infections represent a significant global health threat, exacerbated by the scarcity of new therapeutic options, increasing drug resistance, and host toxicity. Sonodynamic therapy (SDT) offers a promising approach to overcoming antimicrobial resistance by enabling...

Peak Shaving and Valley Filling: Reconstructing Cognitive Load in Cultural Heritage VR Through Contextualized Scaffolding

Virtual reality supports immersive cultural heritage communication, yet engagement outpaces understanding. A structural cause is that information about an object is scattered across transient carriers (NPC dialogue, annotations, triggered videos), requiring working-memory integra...

Early-life exposure to polypropylene microplastics and DEHP induces ASD-relevant neurodevelopmental alterations involving mTOR-regulated autophagy impairment

The health risks of polypropylene plastic, a major food-grade polymer, are often underestimated. Current evidence indicates that infants and young children may ingest millions of polypropylene microplastic particles (PP-MPs) daily, accompanied by co-exposure to di(2-ethylhexyl) p...

Tracking the baryon number with nuclear collisions

Baryon quantum number is found to be conserved since baryogenesis in the early Universe. Conventionally, each fractionally charged valence quark is understood to carry one-third of a baryon number. An alternative hypothesis posits that baryon number is instead carried by a baryon...

BifunctionalIonophores for Cuproptosis Activation:Dual Targeting of Copper and Fe–S Protein Homeostasis

Abstract Cellular resilience to therapy often arises from adaptive mechanisms that safeguard iron–sulfur (Fe–S) proteins. Here, we present a rational strategy to overcome such resilience by integrating two synergistic vulnerabilities, copper toxicity and Fe–S cluster homeostasis,...

Probing the jet transport coefficient of cold nuclear matter in electron-ion collisions

Abstract We investigate the transverse momentum broadening~(TMB) of particle production in upcoming electron–ion collision experiments, an important manifestation of jet transport in cold nuclear matter. By considering the effects of parton multiple scattering in nuclear medium w...

Artificial PhotosyntheticHydrogel Microspheres asa Versatile Platform for Programmable CO2 Valorization

Abstract Carbon-negative biomanufacturing is essential for global sustainability. Artificial photosynthesis based on material-microbe hybrid systems holds promise but suffers from inefficient energy supply, phototoxicity, abiotic–biotic incompatibility, and limited product spectr...

Participant-Independent Classification of Autism-Related Visual Attention Patterns from Eye-Tracking Scanpath Images Using a Global–Local Fusion Network

Children with autism spectrum disorder (ASD) often exhibit atypical patterns of visual attention allocation and social-cue processing. Eye-tracking scanpath (ETSP) retains information about fixation points, saccade paths and their temporal changes in the form of images, providing...

Peer victimization and family dynamics in the association between childhood abuse and adolescent non-suicidal self-injury: a cross-sectional moderated mediation study

Childhood abuse is associated with adolescent non-suicidal self-injury (NSSI), but the roles of proximal peer experiences and family context remain unclear. A cross-sectional survey was conducted among 10,179 Chinese students (47.9% female; Mage = 14.16 years, SD = 1.86). A theor...
