The Maximum Product of Sizes of Cross-\({t}\)-Intersecting Families

Abstract. Two families of sets [Formula: see text] and [Formula: see text] are called cross-[Formula: see text] -intersecting if [Formula: see text] for all [Formula: see text] and [Formula: see text]. Determining the maximum possible product of the sizes for such cross-[Formula:...

Counterexamples to the Knaster problem in all remaining dimensions

We construct counterexamples to Knaster's 1947 problem in all remaining cases. For every ambient dimension n ≥ 4, we obtain a real polynomial on R^{n} and n linearly independent points on S^{n-1} whose values cannot be equalized by any orthogonal transformation. These examples se...

The Atiyah-Sutcliffe determinant at five points: positivity and failure of the deletion inequality

To investigate Atiyah's linear independence conjecture, Atiyah and Sutcliffe associated a normalized determinant to each configuration of distinct points in Euclidean 3-space and proposed a hierarchy of nonvanishing and determinant inequalities. We show that this hierarchy separa...

Development of a novel anoikis-related prognostic signature and validation of CD36 as a potential target for reversing 5-FU resistance in gastric cancer

Gastric cancer (GC) remains a leading cause of cancer-related mortality, with chemoresistance and metastasis being primary hurdles to effective treatment. Anoikis resistance is a critical survival mechanism enabling tumor dissemination; however, the cellular heterogeneity of anoi...

AI-accelerated scalable synthesis of nanocrystals for cost-effective photovoltaics

Metal halide perovskite nanocrystals (PNCs) are promising candidates for next-generation optoelectronics. However, their commercial application necessitates low-cost synthesis and processing methods that surpass conventional lab-scale techniques. To address this, we report a liga...

EXTREME VALUES OF DERIVATIVES OF DIRICHLET L -FUNCTIONS

Abstract In this paper, we establish lower bounds for extreme values of derivatives of Dirichlet L -functions in the range 1 / 2 < σ < 1 $1/2<\sigma <1$ 1 divided by 2 less than sigma less than 1 . Compared with the work of Aistleitner et al. [‘On large values of L ( σ , χ ) $L(\...

Programmable Optical Logic Operations Enabled by Multi‐Wavelength Injection in a Fabry–Pérot Laser

ABSTRACT Photonic spiking neural networks (PSNNs) leverage inherently discrete and event‐driven operations, thereby serving as a promising architecture for optical digital logic. However, limited physical degrees of freedom in current schemes often lead to non‐standardized encodi...

Interstitial Rare-Earth Doping of FAPbI3 Perovskite Nanocrystals under Mild Ambient Conditions

Abstract The rare-earth (RE) metal doping strategies have been investigated for many applications in perovskite materials. However, prior approaches to synthesizing RE-doped perovskite nanocrystals (PNCs) have predominantly required harsh synthesis conditions, including an inert...

AccLock: Unlocking Identity with Heartbeat Using In-Ear Accelerometers

The widespread use of earphones has enabled various sensing applications, including activity recognition, health monitoring, and context-aware computing. Among these, earphone-based user authentication has become a key technique by leveraging unique biometric features. However, e...

On the Bioethical Thought of the Yangming School in Ming Dynasty China

Abstract: The bioethical thought of the Yangming School is a crystallization of ideas responding to the crisis of life alienation in the Ming Dynasty. With “Liangzhi (innate moral consciousness)” as the noumenon, “Zhi Liangzhi (extending innate moral consciousness)” as the practi...

Epigenetic silencing of FCGR2A by promoter hypermethylation exacerbates cardiac remodeling in post-myocardial infarction heart failure

Post-myocardial infarction heart failure (post-MI HF) is among the cardiovascular diseases with the highest morbidity and mortality rates worldwide. However, the epigenetic landscape of post-MI HF remains incompletely characterized. Here reduced representation bisulfite sequencin...

Beyond the efficiency trap: Regional AI exposure, AI knowledge, and the asymmetric governance of data-driven value propositions

Artificial intelligence (AI) is reshaping corporate strategy, yet how regional AI exposure (RAE), the intensity of local industry peers' AI inventive activities, shapes firms' data-driven value propositions (DDVPs) remains unclear. Using panel data on Chinese listed firms from 20...

Effectiveness and Safety of Fixed‐Dose Combination Metformin and Empagliflozin in Type 2 Diabetes: A Prospective, Multicenter, Real‐World Study From China

BACKGROUND: This study assessed the real-world effectiveness and safety of a fixed-dose combination (FDC) of metformin and empagliflozin in Chinese patients with type 2 diabetes mellitus (T2DM). METHODS: This prospective, multicenter, real-world study enrolled consecutive patient...

Surface Vibrotactile Texture Feedback: A Scoping Review of Perceptual Evidence, Rendering Strategies, and Evaluation Practices

Surface vibrotactile texture feedback is an important HCI modality for conveying material-related information and supporting multisensory interaction. However, evidence across perception, rendering, actuation, parameter mapping, and evaluation remains fragmented. This scoping rev...

Persistent Zn 2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn 2+ ‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

ABSTRACT Intervertebral disc degeneration (IVDD) is an age‐related disease accompanied by disrupted mitochondrial homeostasis and defective autophagy. Cellular senescence induces ion imbalance, which leads to mitochondrial damage and suppressed autophagic flux; nevertheless, the...

Density of Triple Coincidences in the Simple Length Spectrum of One-holed Tori

We prove that, in the Teichmüller space of one-holed tori with any fixed boundary length, including the cuspidal case, marked hyperbolic one-holed tori with three distinct simple closed geodesics of equal length form a dense, meager subset. This answers a suspicion of McShane and...

Rapid reliability assessment and mechanistic insight of Cu@Ag-metallized SHJ solar cells under acetic acid vapor aging

Low-temperature Ag-coated Cu (Cu@Ag) paste has been widely adopted as a standard electrode material for silicon heterojunction (SHJ) solar cells, driven primarily by escalating cost-reduction pressure and growing demands for manufacturing sustainability through reduced reliance o...

Density of Triple Coincidences in the Simple Length Spectrum of One-holed Tori

We prove that, in the Teichmüller space of one-holed tori with any fixed boundary length, including the cuspidal case, marked hyperbolic one-holed tori with three distinct simple closed geodesics of equal length form a dense, meager subset. This answers a suspicion of McShane and...

Cohn Trace Polynomials: Root Localization, Strict Log-Concavity, and Rearrangement Inequalities

We study the one-variable trace polynomials obtained from words in the rank-two free group by the Cohn normalization. We prove that every nontrivial word has all its zeros in a fixed sector about the negative real axis; after the marking involution, this is equivalently a transla...

Mechanism-Driven Risk Assessment of 1,3,6-Tribromocarbazole: An Integrated Strategy Implicates ESR1-Associated Cardiovascular Toxicity

Abstract Polyhalogenated carbazoles (PHCZs) are globally distributed emerging persistent organic pollutants, yet their cardiovascular hazards remain largely uncharacterized. We therefore built an adverse outcome pathway (AOP)-guided prediction-to-validation strategy─coupling envi...
