A novel spatiotemporal multivariate partial grey model for multi-segment traffic flow and its application

Purpose The traffic flow system is a complex dynamic system, and the traffic flow data have complex spatiotemporal characteristics. Therefore, to deeply explore the spatiotemporal characteristics of traffic flow data, a novel spatiotemporal multivariate partial grey prediction mo...

Multimodal Trilemma GNN‐LLM‐XAI Framework Resolving Accuracy Transparency Comprehensibility in E‐Commerce Fraud Detection

ABSTRACT E‐commerce platforms face an escalating challenge from sophisticated financial fraud and cyberattacks, yet current detection systems suffer from a fundamental trilemma: achieving high detection accuracy, providing expert‐level transparency, and ensuring user comprehensib...

Tunable Zeeman Splitting in GaAs 1− x − y N x Bi y Nanowires by Axial Uniaxial Stress

The realization of large and tunable Zeeman splitting and the effective g factor is key for spin control in spintronics and quantum information processing. Although marked Zeeman splitting and effective g factor have been demonstrated in GaAs 1− x Bi x nanowires, the effects of n...

Distinct Nodal Centrality and Connectivity Profiles Underlying Independent and Interdependent Self-Construal: A Graph-Theoretical Resting-State fMRI Study

Background/Objectives: Self-construal—the extent to which the self is construed as autonomous from or connected with others—shapes cognition and social behavior, yet its system-level neural architecture remains poorly understood. This study examined whether independent and interd...

Angular and invariant-mass observables in the four-body Higgs decay $$ h\to \ell {\overline{\nu}}_{\ell }{\overline{\ell}}^{\prime }{\nu}_{\ell^{\prime }} $$

A bstract We study the angular distribution of the Higgs boson decay $$ h\to \ell {\overline{\nu}}_{\ell }{\overline{\ell}}^{\prime }{\nu}_{\ell^{\prime }} $$ h → ℓ ν ¯ ℓ ℓ ¯ ′ ν ℓ ′ with ℓ ≠ ℓ ′ . Due to the presence of two undetected neutrinos, a complete angular analysis is no...

Multi-time scale analysis of loess landform evolution for Dongzhi tableland, southwestern Loess Plateau, China

Study region Dongzhi tableland, southwestern Loess Plateau, eastern Gansu Province, China. Study focus The loess tableland has shrunk greatly over the past thousand years, and this trend is expected to continue. Predictions of loess tableland evolution can support the design and...

Deciphering migration dynamics of individual cells using a trajectory-based dynamic reconstruction approach

Abstract Cell migration, which is strictly regulated by intracellular signaling pathways and extracellular microenvironments, is crucial for physiological and pathological processes such as cancer. However, there is a lack of efficient approaches to analyze statistical and time-v...

Fault diagnosis of marine diesel engine via control-aware domain-adversarial network: A control-diagnosis collaboration perspective

Aiming at the issue that existing fault diagnosis methods for marine diesel engines often neglect the diagnostic value of information contained in control signals, this paper proposes a control-aware domain-adversarial network for injector system fault diagnosis across maneuverin...

Large-scale esophageal cancer screening through noncontrast computed tomography and artificial intelligence

The absence of accurate, noninvasive, scalable screening tools keeps early esophageal cancer (EC) detection a global health challenge. Although noncontrast computed tomography (NC CT) is widely accessible, the esophagus is a hollow tubular structure prone to collapse and motion a...

Graph neural network-based service migration decision in vehicular networks

Abstract The rapid development of the Internet of Vehicles (IoV) has led to an exponential increase in the number of latency sensitive and computationally intensive tasks. Due to the limitations of onboard computing resources in vehicles, offloading these tasks generated during v...

High‐Pressure Synthesis of Quantum‐Stabilised Manganese Superhydride MnH 7

ABSTRACT Through high‐temperature, high‐pressure diamond anvil cell studies combined with in situ synchrotron powder x‐ray diffraction, we investigate the reactivity between manganese and hydrogen up to 182 GPa. Laser heating manganese in an medium at 118 GPa yields body‐centred...

Encoder Choice Outweighs Modular Refinement in U-Net Architectures for Globally Distributed Coseismic Landslide Segmentation

Rapid post-earthquake landslide mapping is critical for emergency response, yet the quantitative hierarchy of architectural choices in U-Net-based segmentation remains unresolved. Using the Globally Distributed Coseismic Landslide Dataset (GDCLD; nine earthquakes, four continents...

Adaptive stochastic resonance with period guidance for blind bearing fault detection

To address the limitations of stochastic resonance (SR) methods based on signal-to-noise ratio (SNR) in blind fault detection of rolling bearings, a periodicity-guided adaptive SR method is proposed. First, an adaptive weighted squared envelope correlation sparse deconvolution me...

MF-DETR: an efficient end-to-end framework for small object detection in UAV imagery

Unmanned aerial vehicle (UAV) object detection plays an important role in intelligent transportation, environmental monitoring, and public safety. However, UAV images usually contain dense small objects, large scale variations, occlusion, and complex background interference, maki...
