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...

A compact piezoelectric inertial bone-conduction transducer with broadband vibration response

Externally worn bone-conduction devices suffer from high-frequency vibration attenuation induced by the low-pass filtering effect of the skin-soft-tissue layer during transcutaneous vibration transmission. Meanwhile, conventional electromagnetic transducers struggle to balance br...

Defect-engineered Ce 3+ -doped borosilicate glass scintillator for multifunctional and environment-adaptive X-Ray imaging

Abstract Advanced scintillation materials capable of simultaneously delivering ultrahigh efficiency, exceptional stability, and multifunctional X-ray imaging remain elusive because of intrinsic trade-offs in conventional scintillators. Hernin, a defect-engineered Ce3+-activated b...

Biological Characteristics and Research Progress of the Rice Leaf Beetle Oulema oryzae (Coleoptera: Chrysomelidae: Criocerinae)

The rice leaf beetle, Oulema oryzae, is a pest across eastern Asia and eastern Russia; both its larval and adult stages cause considerable yield losses through foliar consumption. Its obligate diapause ensures population persistence through adverse seasons, but this strategy also...

Mogroside V Promotes Brown Adipose Thermogenesis via FTO ‐m 6 A ‐ LETMD 1‐ UCP 1 Pathway to Combat Obesity

ABSTRACT Obesity is a chronic, recurrent, and progressive disease caused by energy imbalance. N 6 ‐methyladenosine (m 6 A) modification regulates fat thermogenesis, potentially counteracting obesity. Mogroside V (MV) is a triterpene glycoside extracted from Siraitia grosvenorii a...

Transcriptomic analysis reveals the immune response mechanisms of Acrossocheilus fasciatus against Citrobacter freundii infection

Abstract Acrossocheilus fasciatus is an economically important freshwater fish species in China. In recent years, Citrobacter freundii infection has caused significant harm to the aquaculture industry. In this study, we performed histological observation and RNA‐seq analysis of t...

Beyond the food tray: linking school nutrition and feeding programmes to student health and academic outcomes through health literacy and mental health

School nutrition and feeding programmes are pivotal in addressing both public health and educational challenges, yet their multidimensional impacts remain underexplored in resource-constrained settings. Guided by the Health-Promoting Schools (HPS) framework, this study examined t...

Spin-current-controlled anisotropic deformation of magnetic lump solitons

We investigate a (2+1)-dimensional nonlinear spin system containing an effective spin-current transport term. Based on its integrable structure, exact magnetic lump solutions are constructed on a rotating spin background, including both fundamental and higher-order configurations...

Water-Stable Metal−Organic Framework with a Tuned Pore Microenvironment for Selective Acetylene Separation

Abstract Due to the highly similar molecular dimensions, polarizability, and physicochemical properties among C2H2, CO2, C2H6, and C2H4, these gas molecules always exhibit analogous adsorption behaviors in conventional porous adsorbents. Therefore, the precise and high-efficient...

From automatic detection to segmentation: A label-efficient SAM pipeline with feature-guided star-shape priors for breast ultrasound

Accurate segmentation of breast lesions in ultrasound images is important for quantitative lesion assessment, but remains difficult because of low contrast, noise, and artifacts. The Segment Anything Model (SAM) provides a flexible prompt-based segmentation framework, yet its per...

Thermally Reversible Transformation between Two Isomers of Silver Sulfide Magic-Size Clusters

Abstract Isomers of semiconductor magic-size clusters (MSCs) share the same molecular formula but can exhibit distinct optical and electronic properties. Most of the reported MSC isomers have been so far limited to cadmium chalcogenides. Herein, we report the reversible transform...

Surface and interface engineering of SnO2-based electron transport layers for high-performance and flexible perovskite solar cells

Perovskite solar cells (PSCs) have emerged as a leading photovoltaic (PV) technology, achieving rapid progress in power conversion efficiency (PCE) and promising prospects for scalable, flexible applications. Within these devices, the electron transport layer (ETL) plays a decisi...

FIMA-Net: a network with focused feature interaction fusion module with lightweight scale-aware attention for skin lesion image segmentation

Abstract Accurate segmentation of lesion regions in skin images plays a critical role in computer-aided diagnosis systems for skin lesions. However, due to the inherently complex structure of skin lesion images and the low contrast between some lesion regions and the surrounding...

The Altitude Effect of Stable Isotopes in Rivers Over the Tibetan Plateau

Abstract The altitude effect of stable isotopes in river water is key to paleoelevation reconstruction, yet remains poorly quantified at regional scales due to monitoring challenges. This study compiled river water isotope data across the Tibetan Plateau and used a decision‐tree‐...

Institutional tensions in HIV treatment: challenges in providing free antiretroviral drugs under China’s ‘Four Frees and One Care’ policy

Abstract China’s ‘Four Frees and One Care’ policy provides people living with HIV (PLHIV) with free antiretroviral drugs (ARVs), while the recent inclusion of new ARVs in medical insurance policy has created policy overlap. Guided by the Institutional Analysis and Development (IA...
