Pressure-Driven Topological Reconfiguration toward Fast-Charging Hard Carbon with Plateau-Capacity Retention

Abstract Conventional carbonization of semi-coke induces excessive ordering of aromatic skeletons, producing dense graphitic structures that hinder Na+ intercalation and suppress low-potential plateau capacity. Here, we develop a rapid thermomechanical coupling sintering strategy...

Crack parameter inversion using an ultrasonic-magnetic fusion neural network

Crack defects in ferromagnetic components may lead to structural degradation and safety risks during manufacturing and service. Ultrasonic testing and magnetic memory testing have complementary advantages, but single-modality methods are often limited in quantitative crack parame...

Complete staging surgery and radioiodine therapy were predictive of disease progression of malignant struma ovarii: a retrospective study from a single-center in China and literature review

Malignant struma ovarii (MSO) is a rare subtype of ovarian cancer. We aimed to evaluate the role of complete staging surgery (CSS) and adjuvant radioiodine therapy in this rare malignancy. MSO patients with sufficient information who were treated at the Cancer Hospital & Institut...

The mechanosensitive channel TMEM63B contributes to noxious heat sensation in the dorsal root ganglia

In mammals, heat sensation is primarily mediated by thermosensitive channels, particularly transient receptor potential (TRP) channels, in dorsal root ganglion (DRG) neurons. However, whether additional channels contribute to noxious heat detection remains unclear. Here, we inves...

Paradoxical Association of Body Mass Index With Occurrence and Mortality of Venous Thromboembolism in Hospitalized Patients: A National Hospital‐Based Cohort Analysis

Background The association between body mass index (BMI) and venous thromboembolism (VTE) occurrence and mortality is controversial. This study aimed to investigate the association of BMI with VTE occurrence and mortality and explore the consistency across age, sex, and medical s...

Influenza A (H1N1) virus infection complicated by checkpoint inhibitor pneumonitis

Rationale: Checkpoint inhibitor pneumonitis (CIP) is a common, potentially severe adverse event in cancer patients receiving neoadjuvant immunotherapy, with glucocorticoids as the standard first-line treatment. Traditionally, glucocorticoids are avoided in confirmed viral pneumon...

CEBPA-induced trophectoderm-like cells from pluripotent stem cells enable modeling of trophoblast lineage specification

Abstract Trophoblast lineages are essential for placental development and play indispensable roles in mammalian development. However, the regulatory mechanisms governing trophoblast lineage specification, particularly trophectoderm formation, remain elusive. Here, we show that tr...

Trauma and healing among linguistically minoritised TESOL teachers: agency for change against linguistic racism

Abstract Linguistic racism, understood as a form of “new racism”, continues to marginalise TESOL teachers’. While its traumatic effects are acknowledged, little is known about how teachers experience and heal from such trauma. This study seeks to understand how three linguistical...

ZnO-Enhanced Cu/ZrO2 for Photothermal Catalytic CO2 Hydrogenation to Methanol

Abstract The photothermal conversion of CO2 to methanol represents a sustainable pathway for energy storage and carbon neutrality. However, most highly active photothermal catalysts have been evaluated under Xenon-lamp irradiation, in which the photothermal effect arises predomin...

Popularity Regression-Based Latent Space Model for Large-Scale Sparse Network Analysis

Degree heterogeneity is one of the most important properties of network data. It is widely observed that degree heterogeneity is often related to the nodal features. In this study, we investigate the estimation and statistical inference for a popularity regression-based latent sp...

Efficient Offline Policy Optimization under All-Policy Linear Q-Realizability

We study offline policy optimization in finite-horizon Markov decision processes with a finite action set and a known bounded feature map. We assume that the action-value function of every randomized memoryless policy is exactly linear, with coefficient norm at most B, and that t...

Diagnosing Regional Contrasts in May-to-June Surface Ozone Transitions across China

Abstract Ground-level ozone (O3) is a major warm-season air-quality challenge in China, decreasing from May to June in southern China but increasing in North China (NC). Yet the distributional basis of this contrast remains unclear. Using 2015–2025 observations, reanalysis, fire...

Observation-constrained assessment of long-term cropland productivity trends and drivers at the global scale

The cropland ecosystem is closely linked to global food security and carbon budget dynamics. Understanding the trends and drivers of cropland gross primary productivity (GPP) is essential for evaluating potential agricultural yields and for formulating effective adaptation and ev...

Regulation of target gene expression by chromatin-associated protein-coding transcripts in plants

Protein-coding transcripts are regarded as intermediates that mediate DNA-to-protein information flow, leaving their noncoding regulatory potential largely underappreciated. Genome-wide profiling of RNA–chromatin interactions in Arabidopsis has uncovered widespread associations b...

Shifting patterns of Ozone Season due to policy and human activity in Beijing between 2013 and 2023

Abstract. Since 2013, Beijing has implemented a series of stringent measures to control air pollution, resulting in significant improvements in air quality. This study analyzed the variations in ozone pollution in Beijing over the past decade, focusing on the influence of human a...

Under the homeland gaze: migrant mothers’ discursive legitimacy work and the relational negotiation of motherhood

As motherhood extends from the private sphere to the public arena of social media, it can no longer be understood merely as a form of social division of labour. Instead, it becomes an identity position that requires continuous justification and maintenance. Drawing on digital eth...

Orthogonal Fc engineering enables multiplexed delivery of mRNA-encoded bispecific antibodies that constrain viral escape

The continuous antigenic evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has repeatedly undermined the effectiveness of monoclonal antibody (mAb) therapies, underscoring the need for innovative approaches that improve therapeutic mAb breadth and durabili...

Multi-Frame Reconstruction via Clutter Filtering for Computational Contrast-Enhanced Ultrasound Microflow Imaging

Objective: Existing computational reconstruction methods for plane-wave ultrasound imaging (PWI) often neglect the interference of strong tissue signals with weak flow-related scattering signals in microflow imaging. This study aims to develop a multi-frame computational ultrasou...

Evolutionary Genetics of Insect Mimicry and Masquerade

As classic examples of adaptive evolution, insect mimicry and masquerade have been studied extensively for more than a century. Both phenomena protect insects from predators and are widely observed in nature. Previous research on phenotypic, genetic, phylogenetic, and behavioral...

3D Microfluidic Networks Formed by Mechanically Guided Compressive Buckling for Large‐Scale Perfused Tissue Culture

ABSTRACT Engineered tissues and organoids offer transformative potential for drug screening and regenerative medicine, yet their application is constrained by limited size and slow maturation. Despite the development of various channel networks for large‐scale engineered tissue p...
