Transforming waste into multifunctional biochar catalysts for pollution control: Synthesis strategies, catalytic mechanisms, and practical challenges

Abstract Converting waste feedstocks into multifunctional biochar catalysts provides a promising route for coupling solid‐waste valorization with pollution control. However, existing studies often emphasize individual removal performance, while the relationships among feedstock c...

Cultural Tourism Experience and Tourist Satisfaction at a Heritage Site: An Extended ACSI Model

Based on the American Customer Satisfaction Index (ACSI) model, this study incorporates the experiential characteristics of cultural tourism and constructs a theoretical framework encompassing tourist cultural expectations, cultural perceived authenticity, cultural perceived valu...

SAC-Net: Structure-Aware Collaborative Network for Graph Similarity Computation

Abstract Graph Similarity Computation (GSC) is a core task in graph analysis. However, current mainstream GNN-based similarity models still suffer from two fundamental bottlenecks. First, constrained by the inherent mechanism of recursive local aggregation, namely the 1-Weisfeile...

An improved RT-DETR algorithm for small-object detection in UAV aerial images

Abstract To address the challenges of UAV aerial imagery, including the prevalence of small objects, complex background interference, and difficulty in feature extraction that lead to high missed detection rates and compromise detection accuracy in existing RT-DETR algorithms, th...

Effects of different resistance training programs on quality of life and fatigue in cancer patients: a network meta-analysis

To systematically evaluate, via network meta-analysis, the effects of different resistance training intensities on quality of life and cancer-related fatigue in cancer patients, and to identify the optimal exercise regimen. A systematic search of PubMed, Embase, the Cochrane Libr...

Engineering Atomically Precise Cu 4 I 4 Nanoclusters With Integrated Adsorption and Hydrogenation Functions for Efficient Photocatalytic Nitrate‐to‐Ammonia Conversion

ABSTRACT Photocatalytic nitrate reduction to ammonia offers a sustainable route that couples environmental remediation with nitrogen resource utilization. However, this transformation suffers from sluggish kinetics and insufficient hydrogenation, leading to poor selectivity and e...

The association of physical activity with intrinsic capacity: findings from longitudinal analysis in CHARLS and HRS

Abstract Background Physical activity (PA) is a pivotal modifiable determinant of intrinsic capacity (IC), a core component of healthy aging. Aims This study aimed to examine the association between PA and the risk of IC impairment among middle-aged and older adults using nationa...

Trophic transfer of silver nanoparticles in a detritus-based food chain within a karst stream: A comparative study of direct exposure versus trophic transfer

The widespread use of silver nanoparticles (AgNPs) has led to their substantial release into aquatic ecosystems, yet their ecological risks within detritus-based food chains remain poorly understood. This study constructed a model detrital food chain— Pterocarya stenoptera leaf l...

Deep knowledge tracking and course recommendation model for online education learners

Existing course recommendation models struggle to capture the dynamic evolution of learners’ interests, while traditional knowledge tracing methods miss long-term dependencies and neglect topic features and forgetting patterns in long interaction sequences. This study improves bo...

Regulatingthe Arrangement of Planar Ligands in LanthanideMetal–Organic Framework Photosensitizers to Induce a PhotocatalyticReactive Oxygen Species Storm for Sewage Purification and PhotodynamicSterilization

Abstract Constructing lanthanide metal–organic frameworks (Ln-MOFs) that are both water-stable and capable of efficiently generating reactive oxygen species (ROS) remains a significant challenge in the field of photocatalytic water remediation. In this study, two structurally rob...

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...

Plant species identification by genome skimming across the vascular plant tree of life

Summary Accurate species identification is essential for biodiversity conservation and sustainable use, yet standard plant DNA barcoding often fails to achieve species‐level resolution. We present a large‐scale empirical evaluation of genome skimming as a tool to improve plant sp...

Smart Highway Pilots, Carbon Emissions, and Air Pollution: Evidence from China

The digitalization and intelligent transformation of transportation have emerged as technological solutions for enhancing traffic efficiency and reducing traffic-related pollutants. However, existing studies primarily focus on traditional traffic emission reduction measures, and...

Prevalence and associations of biological rhythm disorders with depression and anxiety symptoms in Chinese adolescents: A multicenter study across seven provinces

Biological rhythm disruption is increasingly implicated in adolescent emotional ill-health. We conducted a multicenter cross-sectional survey of 9,498 senior high school students (15–18 years) from seven Chinese provinces. Depressive and anxiety symptoms were assessed with the Pa...

Modulating the Optical and Enzymatic Properties of Polydopamine via Valence Engineering of Tungsten Affording NIR‐II Photoacoustic Imaging and Targeted Therapy of Atherosclerosis

ABSTRACT Atherosclerosis (AS) is a risk factor for various cardiovascular diseases (CVD), and early diagnosis and plaque removal are challenges in the management of AS and CVD. To address these challenges, we designed a tungsten‑doped polydopamine nanoparticle (W‐PDA NPs). The ne...

Teacher support and student engagement in second language education: a systematic review of motivational mechanisms and an integrated framework

Teacher support is widely recognized as an important antecedent of student engagement in second language (L2) education, yet existing research remains fragmented in its conceptualization and differentiation of teacher support, as well as explanation of motivational mechanisms. Th...
