Multimodal Transformer Integrating CT and Pathology for Postoperative Risk Stratification in Stage I Non–Small Cell Lung Cancer

A biologically interpretable multimodal artificial intelligence framework outperformed guideline-based postoperative risk stratification for stage I non–small cell lung cancer and identified patients who would benefit from adjuvant therapy.

Suppressing Spurious Causal Chains in Alarm-Triggered Alarm Phenomena via Liang–Kleeman Information Flow–Max-Min Hill-Climbing Graphs

Due to coupling in industrial control structures, alarm variables may exhibit interconnected variations, leading to the “alarm-triggered alarm” phenomenon, which can contribute to alarm flooding. Causal inference methods can characterize dependencies among alarm variables and hel...

River Cooling Distances of the Xiang River in Hengyang: Spatiotemporal Evolution and Associated Factors Based on LCZ

Rapid urbanization has intensified the urban heat island (UHI) effect, yet the river cooling distance and its associated influencing factors remain poorly understood. We retrieved Land Surface Temperature (LST) from Landsat imagery and mapped Local Climate Zones (LCZs) using the...

Electrolyte- and Catalyst-Free Electrochemical Synthesis of Unsymmetrical Diorganoyl Selenides

Abstract A facile electrocatalytic radical coupling of Katritzky salts with diselenides for the efficient synthesis of various alkyl aryl unsymmetrical selenides has been developed under mild conditions. This sustainable protocol is driven by renewable electrical energy, features...

Tough Hydrogel-Mediated Constrained Assembly of Multidimensional Topological Networks for Synergistic Mechanical-Thermal Enhancement

Abstract The rapid development of high-power flexible electronics demands thermal management materials with both high thermal conductivity and mechanical robustness. However, traditional high-loading thermal management materials suffer from an intrinsic mechanical-thermal trade-o...

Sr-anchoring-directed gradient shell architecture in Sr 2 Fe 1.5 Mo 0.5 O 6- δ cathodes for reversible protonic ceramic electrochemical cells

Abstract Strontium segregation remains a critical challenge for Sr-containing double perovskite cathodes, wherein outward-migrating Sr species accumulate at the surface and severely deteriorate interfacial electrochemical kinetics in reversible protonic ceramic electrochemical ce...

Exact bounds for rank-three matroid basis densities

We determine the maximum asymptotic basis density of rank-three matroids with no U_{3,6} minor: it is 64/81. A uniform gap forces every sufficiently dense simplification to be covered by two lines and one point. This gives weighted stability and the exact finite extremizers for a...

The generation and characterization of CTRP9-CreERT2 knock-in mice for targeting endothelial cell muscle and adipose tissues

Vascular endothelial cells (ECs) exhibit significant diversity in different tissues. To elucidate the distinct physiological roles of individual EC subtypes, genetic mouse lines utilizing the Cre-loxP recombination system are crucial. However, there is still a lack of Cre mouse l...

Disease‐Specific Optimal Blood Glucose Control Strategies in Critically Ill Patients: Retrospective Cohort Study and Network Meta‐analysis

ABSTRACT Background Optimal glucose targets for critically ill patients are likely to vary by underlying condition, yet a ‘one‐size‐fits‐all’ approach persists. Aim Determining disease‐specific glucose thresholds may help achieve the lowest mortality rates. Study Design This stud...

Double-Lock Superpolymer TDN is Used for the Theranostics of HCC

Abstract Hepatocellular carcinoma (HCC) is difficult to diagnose early and treat effectively due to its heterogeneity and lack of highly specific biomarkers. Here, we develop a double-lock superpolymer tetrahedral DNA (TDN) integrated with small extracellular vesicles (SUPDIA) fo...

The vertex cover number of three-intersecting nine-partite hypergraphs

We prove that every nine-partite nine-uniform hypergraph whose distinct edges intersect in at least three vertices has an ordinary vertex cover of size at most four. Combined with the known lower construction of Bishnoi, Das, Morris and Szabó, this gives Ryser(9,3)=4. The compute...

Young bone marrow mesenchymal stem cell-derived exosomes promote perfusion recovery and tissue repair via the miR-455-5p/Bach1 axis after hindlimb ischemia

Lower-limb ischemia caused by peripheral arterial disease (PAD) results in sustained perfusion impairment and tissue injury, and effective regenerative therapies remain limited. Bone marrow mesenchymal stem cell-derived exosomes (BMSC-exos) are a promising cell-free therapeutic s...

Generalized Tuza's conjecture for pair-packing number four

For a finite three-uniform hypergraph, the pair-packing number is the maximum number of edges no two of which share a pair, and the pair-cover number is the minimum number of vertex pairs such that every edge contains a selected pair. We prove that pair-packing number four implie...

A Fano-plane counterexample to a conjecture on intersecting multipartite hypergraphs

We construct a seven-partite seven-uniform hypergraph with 28 vertices and 22 edges in which every two edges meet in at least two vertices and the ordinary vertex cover number is four. The construction is based on the seven lines of the Fano plane and has a cyclic description by...

Sharp exponential edge bounds and flag constructions for multipartite intersecting hypergraphs

We construct strictly t-intersecting r-partite r-uniform hypergraphs with fixed ratio r/t = 3 and arbitrarily large vertex cover number, answering Problem 1 of Bishnoi, Das, Morris and Szabo. The construction attains a sharp universal edge bound: every finite, nonempty, simple hy...

Donor‐Selective NiCo‐LDH Templating Directs Polymer Assembly for Enhanced Exciton Transport in Efficient Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) have achieved remarkable progress, yet improving exciton utilization in polymer donors remains challenging due to their intrinsically limited exciton diffusion length ( L D ). Here, we report a donor‐selective templating strategy based on few‐l...

Dissecting the associations of cardiovascular health, biological aging, and blood DNA methylation signatures with chronic respiratory disease risk

The interplay between cardiovascular health (CVH), biological aging, and underlying epigenetic mechanisms in relation to chronic respiratory diseases (CRDs) remains unclear. We conducted a large-scale prospective cohort study including 181,955 participants from the UK Biobank. Ca...
