Discrimination of Tight Sandstone Reservoir Effectiveness Based on Pore-Throat Functional Fractal Characterization and Three-Dimensional Pore-Network Connectivity Constraints

Tight sandstone reservoir effectiveness is governed not by pore volume alone, but by the storage and flow contributions of different pore-throat scales, their structural complexity, and their three-dimensional connectivity. This study investigates tight sandstones of the Benxi Fo...

Research Progresson Rapid Dissolution Technologyof Polymers for Offshore Oilfields

Abstract As global onshore oil and gas resources gradually become depleted, offshore oilfields are playing an increasingly critical role in energy supply. Polymer flooding represents a highly efficient chemical enhanced oil recovery technique in an offshore oil field, yet its off...

An SPCL-Stacking ensemble learning framework for landslide susceptibility assessment

Abstract Background Machine learning has been increasingly applied to data driven landslide susceptibility assessment. However, false negative label noise introduced during negative sample selection and the limited predictive capability of single models remain unresolved issues....

A Physics-Guided Dehazing Method Based on Polarization Imaging

Haze conditions degrade image quality via atmospheric scattering and absorption, posing challenges for optical imaging applications. In recent years, deep learning has emerged as an effective method for dehazing images. However, data-driven deep learning dehazing methods typicall...

Precise Management of n‐Value Distribution at the 2D/3D Interface Enabling Efficient Wide‐Bandgap Perovskite Solar Cells

Introducing a 2D perovskite layer on the surface of 3D perovskite has been broadly recognized as an effective strategy to enhance the performance of perovskite solar cells (PSCs). However, the mechanism governing the 2D phase formation remains uncertain. In this work, the phase t...

Supply chain resilience in China’s construction industry: spatiotemporal trends and forecast

Construction industrialisation is regarded as a core pathway to improve construction efficiency and reduce resource consumption amid the global urbanisation. However, existing research has verified that the instability of its supply chain system hinders the sustainable developmen...

An Enhanced YOLOv8 Algorithm with C2f_Parnet for Vehicle and Pedestrian Detection

This paper proposes enhancements to the YOLOv8s model for autonomous driving object detection tasks. Firstly, a C2f Parnet module is designed based on the Parnet parallel network architecture to reduce network depth and computational latency. Secondly, GSConv is modified by emplo...

A Caputo Fractional SLBS Computer Virus Model with Stage-Specific Holling Type-II Incidence

Computer virus propagation (CVP) models translate malware movement in a network into analyzable dynamical systems. Two features are especially important for modern networks: infected hosts may remain latent before a damaging burst, and infection efficiency is usually saturated by...
