A boundary-guided strategy via pseudo-anomaly feature perception for unsupervised ECG signal quality assessment

Electrocardiogram (ECG) signal quality assessment is vital for ensuring accurate ECG diagnoses and efficient medical services. Traditional supervised ECG signal quality assessment methods are limited by a restricted set of noise categories, which results in poor generalization ab...

An extended TPB approach to examining Chinese university students’ public and private campus pro-environmental behavior

Extensions of the theory of planned behavior (TPB) commonly incorporate environmental knowledge, connectedness to nature, personal norms, and efficacy beliefs, yet their theoretical ordering and relevance to different forms of environmental action remain less clear. This study ex...

Functional binders toward zinc–iodine batteries: From mechanism to design

Aqueous zinc‑iodine (Zn-I 2 ) batteries have emerged as a promising alternative for grid energy storage, yet their practical application is critically plagued by the polyiodide shuttle effect, sluggish iodine redox kinetics, and unstable zinc anode interfaces. Although extensive...

Ultrasound-Assisted Extraction of Antioxidant Polyphenols from Zheng’an White Tea: Process Optimization and Bioactivity

White tea is rich in polyphenols with antioxidant potential, but information on Zheng’an white tea remains limited. This study optimized water-based ultrasound-assisted extraction (UAE) using single-factor experiments and a Box–Behnken design and evaluated the antioxidant activit...

MSRA-CCL: Multi-Source Reliability-Aware Aggregation and Cross-Domain Consistency Learning for Weakly Supervised Sentiment Classification

Sentiment classification often relies on costly in-domain annotations, while weak-supervision sources provide low-cost but inconsistent labels. We propose Multi-Source Reliability-Aware Aggregation and Cross-domain Consistency Learning (MSRA-CCL) for weakly supervised sentiment c...

Monarchy and political collaboration in John Heywood's The Play of the Weather

John Heywood's The Play of the Weather (1533) reflects the dynamic complexity of early Tudor political thought. This article intervenes in critical debates by challenging the tendency to reduce the play's politics to Catholic conservatism. While prior scholarship frames the text...

Doping PEDOT:PSS with a cobalt complex boosts organic/silicon hybrid solar cell performance

PEDOT:PSS/silicon hybrid solar cells have attracted much attention due to their simple fabrication process and low cost. However, the pristine PEDOT:PSS layer suffers from low electrical conductivity and a relatively low work function (WF), which severely limit the performance of...

Does socially induced negative affect influence high‐calorie food intake in adolescents? The role of emotion regulation strategy

Abstract The prevalence of adolescent obesity is closely linked to excessive consumption of high‐calorie foods. Although extensive research has demonstrated the influence of emotions and emotion regulation strategies on eating behavior, little is known about the specific role of...

How teacher–student relationships are associated with adolescent suicide risk: a three-wave longitudinal study of perceived burdensomeness and psychological capital

Adolescent suicide represents a critical global public health concern, underscoring the urgent need to identify its underlying psychological mechanisms and protective factors. The present study employed a three-wave longitudinal design over one year with a sample of 1428 secondar...

Quantifying the Incremental Value of XRF Elemental Data for Well-Log-Based TOC Prediction: A Fusion Strategy Evaluated Under Strict Cross-Validation

Total organic carbon (TOC) is a key parameter for source-rock evaluation, but laboratory measurements are sparse and do not resolve continuous vertical variation. Conventional well logs provide continuous physical responses, whereas X-ray fluorescence (XRF) data add geochemical i...

Semantic dependency network approach to the lexico-semantic impairment of Mandarin-speaking patients with probable Alzheimer’s dementia

Background Population ageing has increased dementia prevalence in China, and language impairments represent a prominent behavioral manifestation of cognitive decline.Aims Compared with healthy controls (HCs), this study aims to explore mainland Chinese probable Alzheimer’s dement...

Binary Darboux transformations for a skew-symmetric matrix integrable nonlinear Schrödinger equation

The aim of this article is to construct a class of binary Darboux transformations for a skew-symmetric matrix integrable nonlinear Schrödinger equation. The associated AKNS-type Lax pairs, corresponding to the orthogonal Lie algebra so(2m), provide the framework necessary for sys...

Water‐stable imidazole‐based ionic liquid‐functionalized metal–organic framework for efficient C 2 H 2 / CO 2 separation

Abstract Efficiently sieving C 2 H 2 from CO 2 remains a significant challenge due to their similar molecular sizes and physical properties. To address this issue, we developed a novel strategy for selectively sieving C 2 H 2 from CO 2 by functionalizing metal–organic frameworks...

Confined Predesolvation in a Yolk–Shell Metal–Organic Framework Interphase Enables Reversible Lithium-Metal Anodes

Abstract Artificial interfaces for lithium-metal anodes typically regulate nucleation after Li+ desolvation, while the preceding solvation-to-interface transition remains poorly controlled. Herein, we show that a yolk–shell H-Fe3O4@ZIF-67 interphase can act as a confined predesol...

I2M: a box-based detection framework for molecular structure recognition from images

Accurate recognition and reconstruction of chemical structures from molecular images is critical in cheminformatics, with applications spanning drug discovery, materials science, and patent analysis. However, much of this chemical matter exists in implicit forms that are not dire...

Coherence‐Preserving Fluctuation Diagnostics for an Engineered Population‐Inverted Qubit Otto Engine

ABSTRACT Finite‐time quantum thermal machines require diagnostics beyond average work and efficiency because microscopic engines operate where fluctuations, incomplete thermalization, and coherence strongly affect performance. A coherence‐preserving fluctuation diagnostic is deve...
