A novel method for anomalous behavior detection based on static and dynamic features in social networks

Anomalous activity within social networks poses significant security risks. Detecting such activity is a critical aspect of social network analysis. These activities are often implicitly correlated and temporally dynamic, complicating the representation of discrete actions with e...

Breaking Barriers Toward Practicality: Critical Materials and Strategies for High‐Energy‐Density Aqueous Zinc‐Ion Batteries

ABSTRACT Driven by the demands of grid‐scale energy storage and the electrification of transport, achieving superior energy density is pivotal to establishing a more sustainable and economically resilient battery ecosystem. However, aqueous zinc‐ion batteries (ZIBs), despite thei...

Multi-omics and machine learning reveal the mechanisms underlying cultivar-driven flavor differentiation in fermented ciba chili

Ciba chili quality is strongly influenced by raw material characteristics, but the cultivar-driven mechanisms underlying quality differentiation remain unclear. Ciba chili made from Inner Yellow New Generation (ICP), Lantern (LCP), and Devil's (DCP) peppers was comprehensively in...

Spatiotemporal Patterns and Assembly Processes of Benthic Macroinvertebrate Communities in River Reaches of Different Geomorphic Types in Sichuan Province, China

Geomorphic setting and seasonal variation shape benthic macroinvertebrate communities, but their effects on community patterns and assembly processes remain unclear. We surveyed 49 sites across seven Sichuan rivers during spring and autumn 2025. Reaches were classified as Mountai...

An improved RT-DETR approach for real-time detection of densely occluded blueberries and micro-calyxes

Accurate detection of blueberries and their micro-scale calyx regions is important for visual perception in robotic blueberry harvesting, especially in densely clustered scenes where fruits are frequently occluded and adjacent to each other. However, blueberry calyx detection rem...

Synthesis, Characterization, and Potential Application of Phosphoramide Derivatives as Nitrocellulose Stabilizers

ABSTRACT A series of phosphoramide derivatives were synthesized using POCl 3 and aniline as raw materials. The phosphoramide derivatives can inhibit the self‐catalytic decomposition of nitrocellulose (NC), thereby extending the service life of nitrate‐based propellants. The struc...

Optimization of Ultrasonic Parameters and Model Development for Nondestructive CTE Measurement of LAS Ultra-Low-Expansion Glass Ceramics

Lithium aluminosilicate (LAS) ultra-low-expansion glass ceramics are core materials for precision optical systems, whose quality and dimensional stability are critically constrained by the uniformity of the coefficient of thermal expansion (CTE). This work proposes a nondestructi...

From bubble–particle aggregate formation to froth stability in mineral flotation: mechanistic links and controlling factors

Froth is an indispensable component of the flotation process, and its stability determines both the recovery and the separation efficiency. Accordingly, from the perspectives of the pulp phase and froth phase in the flotation system, this review elucidates the bubble-particle int...

Research on the Application of Prefabricated Pavement Slabs in Non-Conventional Natural Gas Drilling Projects

In recent years, traditional cast-in-place concrete construction for pre-drilling engineering in unconventional natural gas fields has generated large amounts of waste concrete, consumed significant resources, and prolonged project schedules. To address these issues, this study p...

Lattice matching dictates the growth mode and quality of deuterium crystallization in confined spherical shells

Cryogenic hydrogen isotope fuel layers with high structural integrity and atomic-scale smoothness are prerequisites for symmetric implosion and ignition in inertial confinement fusion (ICF). Using deuterium (D2) as model fuel, we perform large-scale molecular dynamics simulations...

Dissecting a novel Fusarium head blight resistance QTL TaFhb-6A in wheat Line R111 using integrated multi-omics strategies

Fusarium head blight (FHB) is a devastating fungal disease that threatens wheat yield and quality worldwide. Breeding FHB-resistant cultivars is the most sustainable solution, whereas the narrow genetic basis of resistance has restricted breeding progress. In this study, we devel...

Physics-Aware Enhanced Implicit Neural Representation with Multimodal Feature Fusion for Zero-Shot Super-Resolution of Complex Flow Fields

This study addresses the insufficient representation of key regions, such as shock waves and boundary layers, in classical implicit neural representations (INRs) for super-resolution reconstruction of complex aerodynamic flow fields. A physics-aware enhanced implicit neural repre...

Oxytocin modulates white matter functional connectivity tensor dynamics and circuit-targeted reconfiguration in depressive symptoms

Major depressive disorder involves disrupted neural circuit dynamics. While oxytocin has demonstrated modulatory effects on functional connectivity, its therapeutic potential for depression, particularly through white matter circuit modulation, remains poorly understood. Here we...

Coordination Environment Modulation of Laser Sensitivity in Copper(II) APTTz Energetic Complexes: From Aqua to Perchlorate Ligation

Abstract Coordinated water is a major obstacle in the design of high-performance energetic coordination complexes because inert aqua ligands lower energy density and suppress laser sensitivity. Herein, we report a simple strategy for removing coordinated water by changing the Cu:...

Dendrocalamus farinosus SAUR36 is involved in growth regulation and drought tolerance

Some characterizations of rings whose regular ideals are G -projective

Abstract In this paper, regular modules are introduced to characterize rings whose regular ideals are G -projective, called G -Dedekind rings, i.e., R is a G -Dedekind ring if and only if any regular R -module is a G -projective R -module; if and only if R / aR is a QF ring for a...

Multiscale physicochemical evolution of mined coal links structure transport and reaction kinetics during thermochemical conversion

Global reliance on coal for energy generation and chemical production necessitates physics-based frameworks that move beyond empirical bulk characterization toward predictive and sustainable utilization strategies. Coal is a heterogeneous, reactive porous medium whose structure,...
