Stage-dependent performance and molecular subtype-specific relapse patterns on same-session [18F]FDG PET/contrast-enhanced CT in breast cancer

PURPOSE: To evaluate stage-dependent performance of same-session [18F]FDG PET/contrast-enhanced CT (PET/ceCT) for initial breast cancer staging and PET/ceCT-detected relapse patterns during follow-up. METHODS: This retrospective single-centre study included a primary staging coho...

Conjugated fullerene C60 networks: From bonding motifs to multifunctional properties

Conjugated fullerene C60 networks, formed through inter-cage covalent bonding, constitute a versatile carbon platform in which bonding configuration, topology, and dimensionality can be engineered to realize a broad spectrum of multifunctional properties. This review surveys rece...

Distinct Sex-Specific Characteristics of Apoe Deficient and Ldlr Deficient Mice in Atherosclerosis: Implications for Model Selection and Therapy Development

The progression of cardiovascular disease shows significant sexual dimorphism: although females generally develop the disease later in life, they exhibit a higher age-related incidence than males. While current studies have separately reported sex differences in atherosclerotic d...

A Unified Evaluation Protocol and Late-Fusion System for Monocular Per-Object Distance Estimation in Indoor Scenes

Monocular per-object distance estimation aims to predict a metric distance for each detected object from a single RGB image. Although monocular dense depth estimation and monocular 3D object detection are well studied, indoor object-level distance estimation remains weakly standa...

SmartphoneImaging-Based Luminol Electrochemiluminescenceat the Cobalt Electrode for Sinapic Acid Determination

Abstract Developing simple and portable luminol electrochemiluminescence (ECL) systems without externally added co-reactants is important for on-site analysis. Cobalt is a low-cost and redox-active transition metal with favorable electrocatalytic properties toward water-oxidation...

Research on an Absolute Radiometric Calibration Method Based on a Point Source Array

Factors such as the optical point spread function (PSF), intrapixel sensitivity (IPS), and interpixel crosstalk of an imaging system can cause the response to point sources to vary with position, directly affecting the absolute radiometric calibration accuracy of the remote senso...

An N-acetylated daropeptide modulates nematode development

The symbiotic bacterium Photorhabdus is a rich source of bioactive secondary metabolites that mediate tripartite interactions with nematodes and insect hosts. However, natural products of ribosomal origin remain largely underexplored within this ecological niche. Here, we report...

Molecular and Supramolecular Pathways for CO 2 Separation Membranes: Amine‐Functionalized Silica and Hydrogen‐Bonded Organic Frameworks

Efficient CO 2 capture from flue gas is fundamentally limited by the trade‐off between permeability, selectivity, and chemical stability. Amine‐functionalized sorbents (AFS) achieve high selectivity via strong chemisorption, but suffer from kinetic limitations, pore blocking, and...

Hybrid intelligent strategy driving high-dimensional encrypted orbital angular momentum comb multicasting towards optical data-transmission networks

Abstract Achieving higher degrees and dimensions of light is one of the accessible paths for increasing the capacity of optical data-transmission systems. Orbital angular momentum (OAM), owing to its infinite and mutually orthogonal nature, offers a promising carrier for high-cap...

A Universal Precipitation‐Transformation Strategy Toward Low‐Defect Prussian Blue Analogs for High‐Performance Sodium‐Ion Batteries

ABSTRACT Prussian blue analogs (PBAs) are considered promising cathode materials for sodium‐ion batteries (SIBs) due to their low cost and open framework structure. However, their practical application is hindered by intrinsic [Fe(CN) 6 ] 4− vacancies and coordinated water, which...

Study on the Promotion of Methane Hydrate Formation by Surface Modification of Quartz Sand

Natural gas hydrates, with their vast reserves and high gas storage density, have emerged as a highly promising alternative energy source and technology for gas storage and transportation. Wettability, as a core surface property of porous media, directly influences hydrate nuclea...

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patter...

High‐Efficiency and Carbon‐Lean Electrochemical Desalination Enabled by Nucleophilic Engineering of Organic Molecular Electrode

ABSTRACT The worsening global freshwater crisis positions seawater desalination as a critical solution. However, conventional desalination technologies remain constrained by a persistent sustainability trilemma involving high energy consumption, chemical reliance, and substantial...
