Central charges and vacuum moduli of 2d $\mathcal{N}=(0,4)$ theories from class $\mathcal{S}$

We investigate 2d \mathcal{N}=(0,4) 𝒩 = ( 0 , 4 ) supersymmetric theories obtained from a topologically-twisted reduction of 4d \mathcal{N}=2 𝒩 = 2 class \mathcal{S} 𝒮 theories on a Riemann surface. This study addresses subtle aspects of central charges, unbroken gauge groups, an...

Wafer-scale low-symmetry graphene moiré superlattice for integrated quantum rectifiers

Low-symmetry materials unlock rich Berry curvature physics and anomalous transport phenomena that are forbidden in high-symmetry quantum systems through rigorous crystalline symmetry constraints. Current approaches rely on external fields or complex heterogeneous stacking to brea...

Analytical Prediction of Critical Transitions in Oscillator Networks With Non‐Local Links

ABSTRACT A wide range of dynamical systems can be modeled as oscillators coupled through an interaction network. Such frameworks have been widely used to explore the emergence of collective phenomena across diverse applications. Here, we develop an analytical framework for oscill...

Self-buoyant cell-spheroid culture programming multi-spheroid assembly

Tempo-spatially controlled culture and assembly of cellular spheroids are fundamental in engineering tissue-like assembloids for scalable application, yet remain a technical challenge. Here, we show self-buoyant culture of cell spheroids and programmable assembly of multi-spheroi...

Interfacial ferroelectricity at naturally-formed van der Waals interfaces

Sliding ferroelectrics emerge as compelling candidates for next-generation wafer-level non-volatile storage applications with low power consumption and high packing density. However, artificially stacked sliding ferroelectrics with homogeneous/heterogeneous interfaces rely on hig...

A generalizable biopsychosocial risk score for stratifying disease vulnerability in healthy populations

Prospective risk stratification of future adverse health outcomes before clinical onset among ostensibly healthy individuals is an important goal of preventive and precision medicine, yet current tools remain largely disease-specific and do not provide an integrated measure of he...

Sn/Zr Mixed-Metal Clusters in MOFs as Lewis Acid Catalysts for Biomass-Derived HMF Synthesis

Abstract The depletion of fossil fuels has spurred the search for sustainable routes to platform chemicals, yet the efficient conversion of biomass-derived fructose to 5-(hydroxymethyl)furfural (HMF) remains challenging. While Sn-based Lewis acids are promising catalysts for this...

The efficacy and safety of endoscopic resection for multiple rectal neuroendocrine tumors: a retrospective cohort study from a tertiary center

Multiple rectal neuroendocrine tumors (MR-NETs) are rare. There is no consensus on their characteristics and treatment. We aimed to evaluate the efficacy and safety of endoscopic resection (ER) for MR-NETs. We performed a retrospective review of 24 patients with 57 rectal NETs wh...

Age-Associated Differences in Facial Skin Structure in Chinese Women: a Cross-Sectional Study

Facial skin aging is a process leading to structural degradation and visible phenotypical changes. Prior studies examined age-related skin parameters and suggested accelerated changes occurring in the early 30s, yet precise timing remains insufficiently defined, and few assessed...

Risk factors of anterior capsular contraction syndrome in Marfan syndrome after intraocular lens and modified capsular tension ring implantation

Purpose To identify risk factors for anterior capsular contraction syndrome (ACCS) after in-the-bag intraocular lens (IOL) implantation in patients with Marfan syndrome (MFS) and ectopia lentis (EL). Methods This study included patients diagnosed with MFS and EL, who underwent in...

A physics-informed dynamic graph and evidence fusion method for fault alarm detection in building HVAC systems

To address the superposition of normal thermal disturbances and fault characteristics in building heating, ventilation, and air conditioning (HVAC) systems, as well as conflicts among different diagnostic evidence sources, a physics-constrained dynamic graph and multi-source evid...

Retracing Nanjing in the Tang dynasty through A GIS-based study of toponyms in contemporary poems

Previous scholars, drawing mainly on official historical sources, have argued that Nanjing (formerly Jiankang, the capital of the Six Dynasties) was completely destroyed with the defeat of the Chen Dynasty by the Sui Dynasty in 589 and remained desolate throughout the succeeding...

Multi‐Timescale In‐Sensor Reservoir Computing With Composition‐Engineered InSnO Optoelectronic Synaptic Transistors

ABSTRACT Real‐time dynamic visual scenes often involve multiple objects moving at different speeds, requiring in‐sensor computing devices with dynamic responses matched to diverse motion timescales. Existing multi‐timescale reservoir systems generally rely on external biasing and...

Real-world clinical outcomes of trastuzumab deruxtecan in patients with HER2-low metastatic breast cancer

Trastuzumab deruxtecan (T-DXd) is an antibody-drug conjugate (ADC) approved for HER2-low metastatic breast cancer (mBC), showing improved survival outcomes in clinical trials. However, real-world evidence on its effectiveness among Chinese patients remains limited. Patients with...

Organic–Inorganic Dual‐Nanofiber Interpenetrating Network Scaffolds for Complementary Enhancement of Mechanical Stability and Osteogenic Bioactivity

ABSTRACT Incorporating nanofibers into 3D‐printed scaffolds is an effective strategy to enhance the physicochemical properties and osteogenic bioactivity of bone tissue engineering constructs. In this study, we developed a composite scaffold featuring a dual‐nanofiber interpenetr...

Macrophage-derived MMP14 fosters immunosuppressive tumor microenvironment by regulating soluble semaphorin 4D

Abstract High expression of semaphorin 4D (SEMA4D) in tumor cells fosters an immunosuppressive tumor microenvironment (TME), yet the underlying tumor-macrophage crosstalk remains poorly understood. Here, we investigated this regulatory axis using in vitro co-cultures and SEMA4D g...

A dual-cubic proof of the four-point hyperbolic Atiyah conjecture

The hyperbolic Atiyah conjecture assigns a binary form of degree n-1 to each point of an n-point configuration in hyperbolic three-space and asserts that the resulting forms are linearly independent. We give a complete geometric proof for four points. Starting from Malkoun's dual...

Decomposition of the systemic immune-inflammation index reveals neutrophil- and lymphocyte-driven, non-linear risk of progression from mild cognitive impairment to dementia

The progression from mild cognitive impairment (MCI) to dementia represents a critical intervention window. The systemic immune-inflammation index (SII) integrates neutrophil, platelet, and lymphocyte counts and has been proposed as an accessible marker of this progression. Becau...

Learning to Simulate: Generative Metamodeling via Quantile Regression

Stochastic simulation models effectively capture complex system dynamics but are often too slow for real-time decision making. Traditional metamodeling techniques learn relationships between simulator inputs and a single output summary statistic, such as the mean or median. These...

Associations between vaccine misinformation and influenza vaccine uptake: a population-based interrupted time-series study in China

Abstract Vaccine misinformation is linked to vaccine hesitancy, yet real-world evidence of its association with vaccine uptake remains limited. Most existing studies rely on self-reported intentions or experimental designs, offering little insight into population-level behavioura...
