A nonlinear stiffened-panel substructure method for efficient prediction of hull girder ultimate bending strength

The reliable prediction of hull girder ultimate strength has long been a cornerstone of ship structural design, but current numerical approaches either rely on oversimplified empirical formulas that lack generality or demand prohibitively high computational costs that hinder prac...

A risk-aware multimodal temporal reinforcement learning approach for collision avoidance of unmanned surface vehicles in multi-dynamic-obstacle scenarios

This study addresses autonomous collision avoidance for unmanned surface vehicles in multi-dynamic-obstacle maritime scenarios, where the number of obstacles varies, risk interactions are complex, and dynamic environmental evolution is difficult to exploit effectively. A Risk-Awa...

Biomimetic recombinant humanized type III collagen peptide-RGD loaded alginate hydrogels enhance proliferation of mesenchymal-lineage cells via Integrin α5β1 activation

Alginate hydrogels (HG) are widely utilized in tissue engineering due to their biocompatibility and tunable physical properties, however, their bio-inert nature limits direct cellular interactions. Moreover, the receptor-level interactions of recombinant humanized type-III collag...

Lightweight multiscale time-series mixing with periodic encoding and physical constraints for ultra-short-term photovoltaic power forecasting

Photovoltaic (PV) power generation is crucial to modern power systems, yet its output exhibits significant randomness, volatility, and periodicity due to factors like solar irradiance and cloud cover, posing severe challenges to grid dispatch. Existing ultra-short-term forecastin...

Interfacial Coordination and Dimensional Confinement Enable Continuous Thin MOF-on-MOF Membranes for Ion Sieving

Abstract Metal–organic frameworks (MOFs) with crystallographically defined pores and chemically programmable internal structures are attractive candidates for regulating ion transport at the molecular scale. Yet, it is still difficult to grow MOF-on-MOF structures as continuous t...

The Water-Sediment Regulation Scheme Drives Phytoplankton Dynamics in the Yellow River Estuary

The Water-Sediment Regulation Scheme (WSRS) of the Yellow River is a large-scale anthropogenic intervention designed to alleviate downstream channel siltation, yet its long-term ecological effects on estuarine phytoplankton communities remain contentious. Based on a 12-year (2011...

Seasonal wet–dry transitions reveal contrasting microbial stability and nutrient cycling across floodplain lake habitats

Abstract Saucer-shaped sub-lakes in floodplains undergo strong seasonal changes in water level and connectivity, but their microbial responses and roles in nutrient cycling remain poorly understood. Here we show, using 28 lake units across Lake Poyang, China, that seasonal hydrol...

Strong tropical cyclones have a more gradual increase trend through interaction with ocean subsurface

Understanding changes in global tropical cyclone (TC) intensity and their long-term trends is critical for enhancing societal resilience. Given their disproportionate impacts, shifts in strong TCs, which are defined here as Category 4 and above, are of particular concern. We exam...

Year-Round High-Resolution Sea Ice Freeboard Retrieval Using ICESat-2 ATL03 Photon Data

Abstract. Arctic sea ice freeboard is critical for estimating ice thickness and characterizing surface morphology, yet it remains poorly constrained, especially during the melt season due to limitations in conventional altimetry products. The ICESat-2 ATL07 product retrieves surf...

Hydrodynamic optimization of a heaving buoy for enhanced wave energy absorption

This study presents a hydrodynamic analysis of an optimised heaving buoy for a single-body point absorber wave energy converter (WEC). A conventional deep-draft cylindrical buoy is modified into a composite single-body configuration consisting of three rigidly coupled sections to...

Projected burden of humid-heat on paediatric asthma in Shanghai under climate change scenarios: A time-series study

Climate change is intensifying the frequency and severity of extreme heat events. While the impact of temperature on respiratory health is well-documented, the synergistic effects of combined heat and humidity are less clear, especially for children, a population with heightened...

Identification of key hub genes in response to acute hypoxia stress under different chronic salinities of giant freshwater prawn based on WGCNA analysis

The salinity and hypoxia in inland and estuarine waters would cause stress on crustaceans especially the catadromous species. The giant freshwater prawn ( Macrobrachium rosenbergii ) is a typical catadromous species which naturally spawn and hatch in estuarine waters and grow up...

Species-resolved baselines reveal limited diagnostic resolution of aggregate river-fish indicators: evidence from a 16-year lower Yangtze survey

Aggregate catch and biomass are widely used to evaluate river restoration and fishery closures, but their management value depends on whether they resolve changes in the species of concern. We evaluated this diagnostic resolution using a 16-year fixed-station survey (2002–2017; 5...

Chemosymbiotic trophic strategy in an Ediacaran tubular animal

Chemosymbiosis may have been a key driver of early animal evolution and diversification. Yet evidence for animal–microbe nutritional partnerships in the fossil record of early metazoans remains scarce, largely owing to the limited availability of robust geochemical proxies and su...

A PPO-based PI tuning scheme for pitch control of floating offshore wind turbines

Abstract Blade pitch control is critical for stabilizing floating offshore wind turbines (FOWTs) in above-rated regions. However, conventional proportional-integral (PI) controllers, typically derived from simplified linear models, often suffer from model mismatch and limited cap...

Green Versus Brown Assets Under Stress: Who Hedges Energy and Market Risk?

Sustainable finance increasingly treats green assets as instruments for climate-risk hedging; however, it remains unclear whether they protect investors during energy-market shocks and financial-market stress or merely transmit different transition, equity-market, and growth risk...

Preliminary Kinetic Assessment of Quality Deterioration and Shelf-Life Estimation in Yellowfin Tuna Under Different Constant Storage Temperatures

The quality of yellowfin tuna is highly vulnerable to microbial proliferation, which accelerates quality deterioration and spoilage throughout storage. In this study, the dynamic changes in biogenic amines (BAs), total volatile basic nitrogen (TVB-N), and total plate count (TPC)...

Study on the Accumulation, Excretion, and Distribution of Cadmium in Mice After Dietary Exposure to Cadmium-Rich Swimming Crab Portunus trituberculatus

To investigate the patterns of cadmium accumulation and distribution in mice following oral ingestion of cadmium-enriched Portunus trituberculatus, this study selected 4-week-old ICR mice as a model organism. A control group was fed a standard diet, while an exposure group was fe...

Discovery of a novel MurA inhibitor via AlphaFold 3 model-based virtual screening

S. aureus is one of the most important bacteria associated with human diseases. UDP-N-acetylglucosamine 1-carboxyethylene transferase (MurA) is an important enzyme involved in the synthesis of peptidoglycan in bacterial cell walls. The crystal structure of MurA from S. aureus has...

Global Disparities in the Recreational Fishery Economy: A Systematic Review

Recreational fisheries contribute significantly to global economies through tourism, employment, and ecosystem service valorization. However, a systematic understanding of their economic magnitude and regional disparities remains fragmented. This study conducts a systematic revie...
