Guarding the Lifeline: A First Look and Automated Defect Diagnosis for ROS Central Index

The Robot Operating System (ROS) relies on a centralized dependency index, the rosdistro central index , to manage packages across its heterogeneous software ecosystem, which integrates independently evolving Operating System (OS) repositories for system libraries, ROS repositori...

ReFun: Reconstructing Function Boundaries in EVM Bytecode

Recovering the structure of a Solidity smart contract from its deployed bytecode is a prerequisite for various downstream analyses, such as control-flow graph construction, decompilation, and clone detection. A central step in this task is identifying private functions. However,...

Understanding and Improving Model Editing for Secure Code Generation

Large language models (LLMs) are widely used for code generation but may reproduce vulnerabilities learned from insecure training data. Prior work mainly relies on inference-time hardening, which introduces auxiliary components and runtime overhead. We present the first systemati...

Measuring the novelty of biomedical papers using the latent distances between knowledge units

Measuring the novelty of scientific papers is a central concern in research evaluation and scientometrics. From a recombination perspective, prior studies have largely focused on the co-occurrence of knowledge units to assess the novelty of scientific papers. However, these studi...

Inferring 1-Minimal Trigger Configurations for Assessing Linux Kernel CVE Triggerability

Vendors assessing Linux kernel CVEs need to know whether a bug is triggerable under production-tailored configurations, not merely whether a version is affected, yet upstream reproducers and vulnerability databases rarely provide configuration-level context. We study minimal trig...

Design of Multi Liquid‐Based Ultra Broadband Metamaterial Absorbers With Multilayer Architected Resonances

ABSTRACT The limited absorption performance of single‐liquid metamaterial absorbers within the S and C bands remains a significant challenge. To address this issue, this paper proposes a multi‐liquid‐based ultra‐broadband metamaterial absorber featuring three architectured resona...

Hot Corrosion Behavior and Mechanism of Ru-Containing Ni-Based Single-Crystal Superalloy Exposed to Molten Na2SO4 at 950 °C

In this study, the hot corrosion behavior of a low-Cr, Ru-containing nickel-based single-crystal (SX) superalloy under exposure to Na2SO4 corrosive environments at 950 °C for up to 200 h was systematically investigated. The hot corrosion kinetics of the alloy exhibit a typical tw...

A Near-FCI Framework for Vibrationally Resolved X-ray Absorption Spectra

Abstract We present a near-full configuration interaction framework based on iterative configuration interaction with selection and second-order perturbation theory (iCIPT2) for simulating vibrationally resolved X-ray absorption spectra. By combining high-fidelity potential energ...

Ultrasound‐Responsive Extracellular Vesicle‐Encapsulated Piezoelectric Nanoparticles for Chronic Inflammatory Pain Suppression

ABSTRACT Chronic inflammatory pain is characterized by the long‐term coexistence of central sensitization and neuroinflammation. Electrical stimulation has been demonstrated to be an effective strategy for alleviating chronic inflammatory pain. However, implanted electrodes have...

Pathways and mechanisms for layer-wise regulation during laser powder bed fusion of horizontal overhang structures

Laser powder bed fusion (LPBF) enables the freeform fabrication of complex metallic components, yet stable support-free forming of horizontal overhang closure structures remains a major challenge because of severe thermal stress accumulation, insufficient transient support, and p...

Transport-of-intensity diffraction tomography with nonuniform axial sampling (TIDT-NAS)

Abstract Transport-of-intensity diffraction tomography (TIDT) extends the transport-of-intensity equation (TIE) from 2D phase retrieval to 3D refractive index (RI) tomography, enabling non-interferometric volumetric imaging under partially coherent illumination. By combining para...

ROOTS: recognizing oracle bone inscriptions via an organized tree structure

Oracle bone inscription recognition is hindered by long-tailed class distributions and strong inter-class visual similarity. Existing augmentation and re-weighting methods modify samples or optimization while retaining competition within a flat label space. We propose ROOTS (Reco...

Synthesis of Fe-Co Bimetallic Supported on Cotton Residue Biochar: Catalytic Performance and Mechanistic Investigation for CO2 Hydrogenation

Biochar carriers were prepared from cotton residue waste, and Fe-Co bimetallic catalysts with different ratios were constructed using impregnation method. Their catalytic performance in CO2 hydrogenation to hydrocarbons was investigated. The structural evolution and catalytic beh...

Risk–service mismatches reveal conservation and restoration priorities in China’s major urban agglomerations

Rapid urbanization can expose high-value ecosystems to disturbance while degrading ecological functions elsewhere. We combined the landscape ecological risk index ( LERI ), ecosystem service value ( ESV ), spatially validated machine learning and bivariate zoning to assess risk–s...

Quantitative analysis of intersecting pentagon drawings for interpretable cognitive impairment screening

Background The intersecting pentagon drawing task in the Mini-Mental State Examination (MMSE), also referred to as the Pentagon Drawing Test (PDT), is a brief cognitive screening tool in Alzheimer's disease (AD) and other cognitive disorders. However, conventional manual scoring...
