Dyadic coping and factors associated with prenatal depression and anxiety profiles: a couple-level latent profile analysis study

The transition to parenthood is a critical period for psychological adjustment in both partners. While dyadic coping (DC) plays a central role in regulating stress within couples, few studies have explored how joint coping patterns relate to distinct combinations of maternal and...

DBFA-Net: Diffusion-Based Bidirectional Fusion and Axial Attention Network for medical image segmentation

In recent years, Denoising Diffusion Probabilistic Models (DDPMs) have shown strong modeling capability and are increasingly applied to medical image segmentation tasks. However, existing diffusion models still struggle with fine-grained structures and multi-scale context, partic...

Selective Control of Photocatalytic [2 + 2] Cycloaddition versus Isomerization Using Anthraquinone Photosensitizers

Designed anthraquinone photosensitizers enable selective switching between chalcone [2 + 2] cycloaddition and E/Z isomerization. The α-trifluoromethyl group drives isomerization (5:95), whereas the β-tert-butyl group with polychloro substituents promotes cycloaddition (98% yield)...

Design and Performance of Salami-Structured Polymer Alloys by Reactive Blending: Toward Light-Weight, Superior-Toughness, and High-Strength Materials

Abstract Design of polymer alloys that combine lightweight, high-strength, and superior toughness has been a long-standing motivation toward emerging technologies while still facing ongoing challenges. Inspired by the unique salami microstructure in commercial HIPS, here, we pres...

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

ABSTRACT In this work, we report for the first time an organocatalytic system for the enantioselective tandem electrophilic disulfuration/dearomative spirocyclization/oxa‐Michael addition of alkynes. The highly electrophilic saccharin‐derived disulfurating reagent, independently...

Formation mechanism of the digital literacy divide among farmers: a qualitative study from China

Based on in-depth interviews with 30 Chinese farmers, this paper adopts a qualitative research approach to explore the formation mechanism of the digital literacy divide among farmers. Findings indicate that personal characteristics, external conditions, and digitalization willin...

Dose‒response relationship between tooth loss and cognitive impairment in older adults

Abstract Background In recent years, associations between oral health factors, including tooth loss, and cognitive function have received increasing attention. However, the dose-response association between tooth loss and cognitive impairment remains incompletely understood. Obje...

When AI narratives shake the market: AI-washing and idiosyncratic stock return volatility in China

This paper examines whether AI-washing destabilizes stock prices. Using 28,107 firm-year observations for Chinese A-share-listed firms from 2010 to 2024, we measure AI-washing as AI narrative intensity unexplained by observable AI investment. Firm- and year-fixed-effects estimate...

Tailoring the thermal conductivity of boron nitride-based materials through microstructural and architectural design for thermal management applications

The escalating power density of modern electronics has intensified the demand for thermal interface materials (TIMs) that simultaneously deliver high thermal conductivity and reliable electrical insulation. Hexagonal boron nitride (h-BN) has emerged as a leading filler candidate;...

Photoactive Chiral Nanoneedles for Site-Selective Cleavage and Broad-Spectrum Inactivation of Viruses

Abstract Respiratory viruses spread through aerosols and contaminated surfaces, yet masks, respirators, and filters only trap pathogens without inactivating them, turning used protective equipment into a secondary transmission source. Here, we report chiral ZnO nanoneedles (L-NNs...

Using Aromatic‐Bridge‐Tuned Dimer Acceptors to Harmonize Photoluminescence Quantum Yield and Crystallinity for Organic Solar Cells Exceeding 21% Efficiency

ABSTRACT Suppressing non‐radiative energy loss (Δ E 3 ) by enhancing the photoluminescence quantum yield (PLQY) of active‐layer materials, particularly the acceptor component, is important for achieving high‐performance organic solar cells (OSCs). A key challenge is how to design...

Improved estimation of net ecosystem CO 2 exchange over North America using LSTM-based flux upscaling (2001–2021)

Accurate estimation of regional-scale terrestrial carbon budgets is of great importance but remains challenging. With particular advantages, the Long Short-Term Memory (LSTM) network method shows potential for improving regional carbon budget upscaling estimations. Here, using LS...

Mitochondria-Accumulating Nonplanar Perylene Diimides Suppress Mitochondrial DNA Transcription for Antitumor Therapy

Abstract Mitochondrial DNA (mtDNA) transcription is an emerging target in cancer therapy. While enzyme-targeted inhibitors like IMT1B block POLRMT, their organelle specificity remains unclear. Here, we report a distinct strategy using mitochondria-accumulating nonplanar perylene...

The domain-specific bias in creativity evaluation: human evaluators favor human-created art, but prefer AI outputs for divergent thinking

Abstract How do humans perceive and evaluate creativity when it is attributed to artificial intelligence (AI)? This research examined how labeling a source as “AI” versus “human” systematically biases creativity evaluations across different domains. In experiment 1 (painting and...

Coderivatives with Respect to a Set of the Normal Cone Mappings and Their Applications

Abstract. Establishing explicit formulas of coderivatives with respect to a set of the normal cone mapping to a polyhedron, the solution set of a variational inequality system, is one of the main goals of this paper. By using our coderivative formulas, we provide a characteristic...

The Cyclophilin Effector TaCYPE1 From the Tomato Leaf Miner Tuta absoluta Suppresses Plant Immunity by Targeting Host RNA‐Binding Proteins

ABSTRACT The leaf‐mining insect Tuta absoluta is a highly destructive pest that deploys candidate effector proteins to modulate host defences; however, the molecular mechanisms underlying this manipulation remain poorly understood. In this study, we characterise TaCYPE1, a predic...

Excitatory neuronal TIA1 in ventral hippocampal CA1 drives antidepressant-like effects via downregulation of Cacna2d1 signaling in mice

Stress is a known risk factor of major depressive disorder (MDD). T cell-restricted intracellular antigen 1 (TIA1) is an RNA-binding protein that regulates mRNA stability and translational repression. However, its roles in MDD remain largely unknown. Here, we found that TIA1 was...

On the short-wavelength stability and the Kelvin–Helmholtz instability of some explicit solutions to the two-layer nonlinear three-dimensional water wave problem

Abstract This study is concerned with explicit solutions in the Eulerian framework to the three-dimensional nonlinear Euler equations with a free surface and an interface. Starting with a depth-dependent density, continuous within the fluid domain, except across the interface, we...
