Guided differential dilated convolutional network for fault diagnosis of hydraulic manipulators

Fault diagnosis for hydraulic manipulators plays a crucial role in ensuring operational safety but still faces challenges in fault localization. To address this issue, a guided differential dilated convolutional network (GDDCN) is proposed in this study. First, a novel interferen...

The power of a name: Surname culture and corporate earnings management

We examine how surname culture influences earnings management in Chinese A-share firms from 2007 to 2023. Firms whose boards exhibit stronger surname culture, measured by the presence or proportion of directors sharing the chair’s surname, engage in significantly less accrual-bas...

Thermal-aware multi-objective optimization of battery swapping station with operational cost and battery degradation considerations

The swift growth in electric vehicle usage and the need for a high-performance energy supply chain have become a research hotspot. The battery swapping station (BSS) approach is considered a promising alternative to conventional charge-only scheme. However, the problem of effecti...

Discovery of Stereoselective UrCYP71AU Oxidases Catalyzing the Final Biosynthetic Step of Rhynchophylline and Mechanistic Insights into 7R and 7S Spiroindole Skeleton Formation

Abstract Rhynchophylline (RHY) is a spiroindole alkaloid that acts on the cardiovascular and central nervous systems. Based on the distribution patterns of 7R and 7S spiroindole alkaloids in U. rhynchophylla, we hypothesize the existence of hirsutine oxidase responsible for 7R an...

Joint associations of non-intact family types and health-risk behaviors with mental health outcomes: evidence from a large-scale survey among adolescents in Shandong Province, China

Rising global divorce rates have increased the prevalence of non-intact families, which may be associated with adolescents’ behaviors and mental health. Non-intact family types (NIFTs) and health-risk behaviors (HRBs) are both associated with adolescent mental health, yet previou...

Narrative Ambiguity Matters

By extracting information from economic news articles, this paper proposes a novel measure of narrative-based ambiguity that captures investors’ attitudes toward narrative uncertainty and exhibits strong in- and out-of-sample predictive power for the stock market returns. It reve...

Dual‐Site Covalent Targeting Enables BD2‐Selective BET Inhibition With Potent Antitumor Activity in Mice

ABSTRACT Bromodomain and extra‐terminal (BET) proteins are validated therapeutic targets for cancer, but clinical translation of pan‐BET inhibitors is limited by dose‐limiting toxicities from non‐selective inhibition of BD1/BD2 domains. Herein, we report the first‐ever domain‐sel...

Examining global competence in less-internationalized settings: a mixed-methods analysis of Chinese EFL students’ writing

In higher education settings where systematic internationalization opportunities remain structurally inaccessible to the majority of students, how global competence manifests is poorly understood. This study investigates how Chinese EFL students in a less-internationalized settin...

Aggregicoccus is a myxobacterial genus inherently deficient in fruiting genes

ABSTRACT Myxobacteria are fascinating and important prokaryotes with remarkable multicellular behaviors, which make them a model system for studying prokaryotic development and cooperation. Although there have been sporadic discoveries of myxobacterial species unable to fruit, it...

ExMODE: A comprehensive resource for extremophile genomic and functional exploration

ExMODE (https://db.genomics.cn/exmode/) integrates 3518 samples to build a unified extremophile resource, which hosts 1.35 billion habitat-specific non-redundant genes, 5.25 million representative protein structures, 67,026 metagenome-assembled genomes (MAGs), and 164,132 biosynt...

A Robust Electrochemical Aptasensor Based on a AuNP/Chitosan Conductive Network for Saxitoxin Detection in Freshwater Samples

Saxitoxin (STX) is a highly potent marine biotoxin, and trace contamination in aquatic environments can pose serious risks to human health. Therefore, reliable detection of low-concentration STX is crucial for water safety monitoring. Here, we developed a robust electrochemical a...

DS-RangeNet: Lightweight Dual-Stream LiDAR Semantic Segmentation for Industrial Indoor Environments

Real-time LiDAR semantic segmentation for industrial AGVs must distinguish repeated structures and weak glass returns while remaining robust to sensor-dependent intensity and tight edge computing budgets. We introduce DS-RangeNet, a lightweight range image network that processes...

Distinct constraints but shared dynamics shape the macroevolution of volatile organic compound chemodiversity

Complex metabolic systems have evolved across the tree of life, producing remarkable chemodiversity, yet the structure and evolutionary modes underlying this diversity remain poorly understood. Here, we investigate the macroevolution of chemodiversity using a comprehensive datase...

Ultra-Wideband Optically Transparent Absorbing Metasurface Based on Multilayer ITO Films

Traditional microwave-absorbing metasurfaces struggle to integrate optical transparency with ultra-wideband and high-efficiency microwave absorption, severely limiting their deployment in optoelectronics-compatible electromagnetic protection. To address this constraint, we propos...

Fe‑Doped Triphenyl-Substituted Triazine Graphdiyne Semiconductor with Room‑Temperature Ferromagnetism

Abstract The modulation of ferromagnetic order in 2D carbon materials has attracted increasing attention for the development of next-generation spintronic devices and multifunctional information storage technologies. In particular, the graphdiyne (GDY) family has been regarded as...

Enhanced Ultraviolet Circularly Polarized Light Detection through Tuning Constitutional Isomers in Chiral Benzo[ ghi ]perylenetriimides

ABSTRACT Chiral perylene diimides (PDIs) are promising candidates for circularly polarized light (CPL) detection due to their intrinsic chirality, outstanding photothermal stability and tunable molecular structures. However, the photocurrent dissymmetry factor ( g ph ) of CPL pho...

Tailoring Vertical Exciton Dissociation Pathways via Hydrogen Bonding for High‐Performance Thick‐Film Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) with thick active layers demonstrate significant potential for scalable roll‐to‐roll manufacturing in industrial applications. However, increasing the active layer thickness triggers unfavorable morphological evolution, compromising vertical ex...

Self‐Stratifying Electrolyte Enables Triple‐Interface Regulation for Highly Reversible Zn Metal Batteries

ABSTRACT Aqueous zinc metal batteries (AZMBs) are challenged by the incompatibility between cathode kinetic demands and Zn‐anode interfacial stability in homogeneous electrolytes. Biphasic electrolytes can spatially decouple the two electrode environments, yet the accompanying li...

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...

Understanding burnout and engagement profiles in EFL context: the role of teacher support and self-determined motivation

Purpose Although burnout and engagement are central to EFL learners’ academic well-being, little is known about how they combine among Chinese university learners and how teacher support and motivation distinguish different profiles. Drawing on Self-Determination Theory (SDT), th...
