Spatiotemporal Prediction of Urban Land Subsidence Using ConvLSTM Enhanced with Spatial Attention Mechanism

Rapid urbanization has increasingly posed risks of inducing land subsidence in newly developed urban districts, posing growing threats to infrastructure safety. This study focuses on a selected rectangular area within the Shannan New District of Huainan City. Based on 94 Sentinel...

Multi-omics insights into the mechanisms and prognosis of IPF

Abstract Idiopathic pulmonary fibrosis (IPF) represents another progressive and devastating interstitial lung disease found across populations, with a prominent male predominance accounting for approximately 70% of cases. Regional variation in IPF-related genetic polymorphisms, e...

Failure mechanism of anchorage bearing structure in deep roadway under superposition of dynamic and static loads

To investigate the mechanical response of anchorage bearing structures in deep roadways under dynamic loading, a physical simulation test was conducted to analyze the evolution of the strain field under combined static and dynamic loads. A mechanical load-transfer model of the an...

NiCo-PBA-DerivedHollow Co–C–N-DopedNiS Nanocages as High-Performance Cathode Materials for Aqueous Zinc-IonBatteries

Abstract Aqueous zinc-ion batteries (AZIBs) have emerged as a promising candidate for next-generation energy storage systems due to their low cost, high safety, and environmental benignity. Nevertheless, the inherent drawbacks of zinc-ion battery cathode materials, including insu...

On the Sum of the Second Zagreb Index and Its Reciprocal Index for Tricyclic Graphs

For a simple connected graph G, let dG(u) denote the degree of a vertex u. The second Zagreb index Z2(G)=∑uv∈E(G)dG(u)dG(v) and its reciprocal index mZ2(G)=∑uv∈E(G)1/(dG(u)dG(v)) are widely studied topological indices in graph theory. Their sum Z2(G)+Z2m(G) has been studied for t...

Controllable Preparation and Enhancement Mechanism of Al2O3 Nanomaterial-Modified Ultrafine Cement Composite Grouting Materials

Using ultrafine silicate cement as the cementitious material, and admixtures such as expansion agent, rapid-setting agent and water reducer as additives, a new type of composite grouting material with high early strength and high toughness was obtained by modification with nano-A...

Pollution assessment and source analysis of heavy metals and nutrients in sediments of Liujiaxia reservoir, upper Yellow River, China

Abstract To investigate the pollution characteristics, ecological risks, and sources of nutrients and heavy metals in the sediments of the Liujiaxia Reservoir, 21 surface sediment samples were collected in August 2025. Concentrations of total nitrogen (TN), total phosphorus (TP),...

CFD-Based Simulation and Optimization of Summer Environmental Conditions in Laying Hen Houses

To address uneven temperature and relative humidity distributions, localized heat accumulation, and insufficient air velocity in an enclosed stacked-cage laying hen house, a three-dimensional computational fluid dynamics (CFD) model of the laying hen house was developed using fie...
