Elevated neutrophil percentage-to-albumin ratio predicts 1-year unfavorable clinical outcome in patients with acute ischemic stroke

To evaluate the prognostic significance of neutrophil percentage-to-albumin ratio (NPAR) in predicting 1-year clinical outcomes following acute ischemic stroke (AIS). In this retrospective cohort study, we analyzed consecutive AIS patients admitted to the Department of Neurology...

Causal reasoning subgraph retrieval for coal mine safety risk assessment

Coal mine safety risk assessment can reduce accidents, but traditional methods rely on subjective expert judgment or isolated sensor monitoring, which cannot assess complex and interrelated diverse security risks. This paper proposes a retrieval-augmented generation (RAG) framewo...

Study on the fracture characteristics controlled by filling ratio in cut-and-fill mining

To mitigate surface subsidence and stope instability induced by an insufficient filling ratio in cut‑and‑fill mining, this study investigates overlying strata fracture characteristics and instability mechanisms by means of similar material simulation, PFC numerical modeling, and...

Regional Photovoltaic Siting in Shaanxi: Integrating Ecological Value and Electricity-Demand Accessibility

Regional photovoltaic screening must reconcile land availability with ecological and electricity-demand priorities. We compared eight photovoltaic siting scenarios in Shaanxi using province-wide or regional weights derived from criterion variability and correlations. Ecological c...

Object-Based Reconstruction of Mining-Associated Water Body Lifecycles from Multisource Satellite Time Series

Mining-associated water bodies are typically mapped as independent annual patches, obscuring their formation, transformation and continuity over time. Changes in visible water therefore need to be distinguished from changes in water body identity and surface state. Here, we devel...

The Influence of Sense of Direction on Egocentric and Allocentric Spatial Reference Frame Representation: An Investigation Utilizing Behavioral and Eye‐Tracking Metrics

ABSTRACT Sense of direction is one of the important factors influencing the egocentric and allocentric reference frame representation in daily wayfinding. Existing behavioral studies have shown a significant correlation between sense of direction and the accuracy of allocentric r...

Hydro-Mechanical Degradation and Progressive Failure of Sandstone–CGFB Composite Structures Under Cyclic Water Immersion: Implications for Water-Induced Instability Risk in Backfilled Goafs

Sandstone and cemented coal gangue-fly ash backfill (CGFB) form composite load-bearing structures in goafs, where repeated water ingress and drainage may weaken stability. This study investigated sandstone–CGFB composite specimens subjected to 0, 3, 6, and 10 water immersion–dryi...

Experimental investigation and mechanistic study of coal dust wetting by [BMIM][HSO4]

Enhancing the wettability of coal dust is of considerable importance for effective dust control in coal mines. In this study, the optimal conditions for enhancing the wettability of Huozhou coal dust (CD) using the ionic liquid [BMIM][HSO 4 ] were determined through an orthogonal...

Carbonate Mineral Dissolution in Coal and the Associated Evolution of Fracture–Macropore Structure under Hot Flue Gas Treatment

Abstract Hot flue gas injection into coal seams shows considerable potential for enhancing gas drainage from low-permeability coal seams; however, how the carbonate mineralogical composition of coal controls its fracture–macropore response to CO2–H2O acidification remains poorly...

Support-load response and mining-induced stress evolution in a deep extra-thick coal seam under single-pass full-height longwall mining

Abstract To clarify the intrinsic relationship between overburden structural instability and strata behavior during single-pass full-height extraction of a deep extra-thick coal seam, this study investigated Panel 140,504 of the Kouzidong Coal Mine using an integrated approach th...

Numerical-Experimental Investigation of surface integrity and kerf characteristics in laser cutting of GFRP using a conical Gaussian heat source

Laser processing of GFRP composites generates a heat‑affected zone (HAZ) which will affect surface roughness and mechanical properties. Conventional heat source models do not consider the Gaussian distribution of heat flux in the thickness direction. This limitation affects the s...

Shear-creep-induced strength degradation of soft–hard interbedded rock masses controlled by layer-thickness ratio: implications for progressive failure of anti-dip slopes

Anti-dip slopes with gently dipping soft–hard interbedded strata (GD-SHIS anti-dip slopes) may exhibit relatively high resistance under short-term cross-layer shearing. However, sustained shear loading can induce soft-layer deformation, shear-parameter degradation, and delayed pr...

Effectiveness and Safety of Fixed‐Dose Combination Metformin and Empagliflozin in Type 2 Diabetes: A Prospective, Multicenter, Real‐World Study From China

BACKGROUND: This study assessed the real-world effectiveness and safety of a fixed-dose combination (FDC) of metformin and empagliflozin in Chinese patients with type 2 diabetes mellitus (T2DM). METHODS: This prospective, multicenter, real-world study enrolled consecutive patient...

Corporate environmental credit rating and social stability: Evidence from capital-labor conflicts in China's polluting industries

Mitigating capital-labor conflicts is essential for maintaining social stability. Using China's Enterprise Environmental Credit Evaluation System (EECES) as a quasi-natural experiment, this study examines the impact of corporate environmental credit rating on capital-labor confli...

A Dual‐Driven Hydrogel Actuator With Programmable Driving Force Enabled by a Shape‐Memory Scaffold and Ion‐Regulated Internal Force Reservoir

ABSTRACT Programmable soft actuators require independent control over both deformation pathways and driving‐force output, yet conventional shape‐memory systems generally encode these functions within a fixed network and therefore exhibit predetermined recovery behavior. Herein, w...

From microseismic monitoring to targeted reinforcement: a data-driven simulation approach for deep tunnel stability

Deep hard-rock tunnels are highly susceptible to localized rock mass damage under the coupling effects of high in-situ stress and blasting disturbances during construction. The complex spatio-temporal evolution of such damage makes real-time identification and mitigation challeng...

Spectral radius and Hamiltonicity in generalized split graphs

A graph G ˆ is a split graph if its vertex set can be partitioned into a clique S and an independent set I , and the cross edges join a vertex in S to a vertex in I . A generalized split graph G is obtained from the split graph G ˆ by replacing each vertex v of I with a clique S...

Microscopic interactions and wetting behavior at the micro/nano-bubble water-coal interface: experiments and molecular simulations

Coal seam water injection is a key technology for pre-wetting and dust suppression prior to mining, with its effectiveness largely dependent on the wetting capability of water on coal. As a novel wetting medium, micro-nano bubble water (MNBW) has drawn increasing attention due to...
