Pure Spin Photocurrent in an Altermagnetic Photovoltaic Battery

Abstract Altermagnets, featuring momentum-dependent spin splitting without net magnetization, provide a promising platform for spintronic functionalities beyond conventional ferromagnets and antiferromagnets. Here, we propose an altermagnetic spin photovoltaic battery consisting...

Deep learning predicts gene rearrangements from histopathology in large B-cell lymphoma

Abstract Large B-cell lymphomas are molecularly heterogeneous mature B-cell neoplasms in which assessment of MYC , BCL2 , and BCL6 rearrangement status contributes to integrated diagnosis, risk stratification, and treatment planning. Fluorescence in situ hybridization (FISH) rema...

An Optical Tracking‐Based Robot‐Assisted System for Spinal Fixation Rod Bending

ABSTRACT Background In spinal pedicle screw‐rod fixation, rod contouring quality influences insertion ease, construct stability, and corrective effect. Conventional bending relies on surgeon experience and is limited by insufficient support, repeated adjustment, and inefficient w...

Transdiagnostic latent factors dissociating depression and anxiety through reinforcement learning

The comorbidity of depression and anxiety has long been recognized. While mainly characterized as mood dysregulation, depression and anxiety symptoms are also manifested in learning and decision-making deficits. However, the specific cognitive mechanisms that are common to both d...

Space‐Based Observation of Decadal Variations of Ammonium Sulfate Aerosols Over Northern China

Abstract The concentrations of ammonium sulfate, an important component of secondary inorganic aerosols, have dropped substantially in the North China Plain (NCP) over the past decade. However, current understanding of its variations is limited by the small number of ground‐based...

Curvature-Enhanced and Chirality-Modulated Anomalous Thermal Transport in Pentagonal Covalent Organic Framework Nanotubes

Abstract The emergence of covalent organic framework (COF) nanotubes extends tubular materials from rigid atomic networks to flexible molecular frameworks, yet their thermal transport properties remain unexplored. Here, based on an experimentally synthesized two-dimensional penta...

The effect of number of children on loneliness: a nationally-representative instrumental-variable study in India

Abstract Background This study aimed to investigate the causal effect of the number of children on loneliness among older parents in India. Methods We used nationally representative data from Wave 1 of the Longitudinal Ageing Study in India (LASI). Our analytical sample comprised...

Heterogeneous social participation profiles and socioecological correlates among community-dwelling older adults: a latent profile analysis

Abstract Background Social participation in later life is often summarized using an aggregate score, which may obscure distinct configurations of everyday, social, and volunteering activities. This study aimed to identify latent social participation profiles among community-dwell...

Early weight bearing with ultrasound monitoring is associated with accelerated functional recovery after open repair of acute achilles tendon rupture: a retrospective cohort study

Optimal rehabilitation after open repair of acute Achilles tendon rupture (AATR) remains controversial. Early weight-bearing may enhance recovery, but its clinical use is limited by lack of objective criteria. This study evaluated the safety and efficacy of an ultrasound-monitore...

Developing a health values framework for patients with cardiovascular-kidney-metabolic syndrome: a qualitative exploration through the lens of social determinants of health

Abstract Background Despite global calls for the advancement of patient-centered care, care planning often remains poorly aligned with patients’ lived social contexts and core values. This study aimed to understand what matters most to patients with cardiovascular-kidney-metaboli...

Case report: Twin pregnancies with heterozygous GDF2-related hereditary hemorrhagic telangiectasia

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant genetic disorder characterized by recurrent epistaxis, mucocutaneous telangiectasia, and arteriovenous malformations (AVMs). Only a few cases related to the variants of the GDF2 gene have been described. Pregnan...

Clinical and imaging characteristics of cervical ossification of the posterior longitudinal ligament and factors influencing its severity: a retrospective cross-sectional study

Abstract Background Although the prevalence of cervical ossification of the posterior longitudinal ligament (OPLL) and its risk factors for onset and postoperative progression have been well documented, a comprehensive profile of patients with this condition remains lacking, and...

Adjunctive posterior tibial tendon transfer during supramalleolar osteotomy for varus ankle osteoarthritis: a matched cohort study

The role of adjunctive posterior tibial tendon (PTT) transfer in supramalleolar osteotomy (SMO) for varus ankle osteoarthritis remains unclear. This study aimed to compare clinical and radiographic outcomes between SMO with adjunctive PTT transfer and isolated SMO, with particula...

Water hardness and all-cause and cause-specific mortality: evidence from a prospective cohort study

The health implications of domestic water hardness remain controversial, with limited prospective evidence on cause-specific mortality. We investigated associations of calcium carbonate (CaCO 3 ), calcium (Ca), and magnesium (Mg) concentrations with all-cause and cause-specific m...

Epididymal Versus Testicular Sperm for ICSI in Obstructive Azoospermia: Embryological, Clinical, and Neonatal Outcomes in a Retrospective Cohort

BACKGROUND: Whether sperm source influences intracytoplasmic sperm injection (ICSI) outcomes in men with obstructive azoospermia (OA) remains uncertain. OBJECTIVE: To compare embryological, clinical, and neonatal outcomes of ICSI using percutaneous epididymal sperm aspiration (PE...

Optic Disc and Retinal Strain Due to Vertical Duction

Purpose: To compare two-dimensional optic disc and retinal vessel strains due to vertical versus horizontal eye rotations in younger and older subjects using confocal scanning laser ophthalmoscopy (cSLO). Methods: In a younger subject group (n = 10; range, 18-39 years; mean age ±...

Electrochemically In Situ Formed Inverse‐Honeycomb Local Ordering for Low‐Voltage‐Hysteresis Oxygen Redox in Na/Li Layered Oxide Cathodes

ABSTRACT In oxygen‐redox cathodes, voltage hysteresis largely arises as oxygen redox generally proceeds with electrochemical reactions followed by chemical reactions that normally drive asymmetrical charge and discharge pathways. Although different superstructures, such as ribbon...

Mechanism-Constrained Learning for Regime-Aware Urban Ozone Prediction and Interpretation

Abstract Accurately characterizing source-related and precursor factors associated with surface ozone (O3) pollution remains a central challenge for air quality management. Data-driven models can achieve strong predictive performance, but mechanistically consistent interpretation...

An Ethical-Legal Analysis Mandatory Influenza Vaccination for Healthcare Workers in China

Healthcare workers (HCWs) face a high occupational risk of influenza infection. Accordingly, the World Health Organization has identified HCWs as a priority group for influenza vaccination and established a target coverage rate of 75%. However, coverage among HCWs in China remain...

B3GNT3 defines a spatially restricted dysfunctional T-cell niche and predicts immunotherapeutic outcomes in lung adenocarcinoma

Abstract Background Immunotherapy response in lung adenocarcinoma (LUAD) remains highly heterogeneous, underscoring the need for biologically informative markers of tumor immune dysregulation. B3GNT3, a glycosyltransferase implicated in several malignancies, is poorly characteriz...
