Numerical study of hydrodynamics and power performance of offshore floating photovoltaic: Effects of connector failure

As a core component of the offshore floating photovoltaic (OFPV) system, connectors exert a decisive influence on the stable operation of the entire multi-float structure. In this study, a coupled hydrodynamic-solar power generation model for the OFPV system is developed. First,...

Cyclic performance of a two-story reinforced-concrete frame strengthened with inverted-V buckling-restrained braces and T-shaped anchorage

This study investigated the seismic performance of a 1/3-scale, two-story, three-span reinforced-concrete frame strengthened with inverted-V buckling-restrained braces (BRBs) and a T-shaped anchorage system. In the tested configuration, two BRBs were installed at each story, with...

Study on friction characteristics at the rolling interface under vertical-horizontal coupled vibration of rolling mill systems based on dynamic rolling force

This study addresses the limitations of conventional steady-state rolling models in characterizing metal flow dynamics and force-energy parameters at the rolling interface under vertical-horizontal coupled roll vibrations. Based on the principle of mass conservation, a three-dime...

A Magnitude–Variability Framework for Dynamic River Water Quality Characterization

Continuous river water-quality monitoring increasingly captures short-term fluctuations that are poorly represented by conventional static assessments, yet frameworks for translating high-frequency observations into interpretable dynamic water-quality states remain limited. In th...

Anticipating Nutrient Risk in Lakes and Reservoirs: A Data-Driven Framework for Sustainable Water Quality Management

Sustainable management of lakes and reservoirs increasingly requires timely knowledge of how nutrient conditions evolve across both space and time. Total phosphorus is a key indicator of nutrient enrichment and eutrophication risk, yet its spatial distribution is highly heterogen...

An underappreciated cyclonic-like circulation affects high summer ozone in North China Plain

China continues to experience severe ozone pollution, particularly over the North China Plain (NCP) during summer. Ozone pollution is generally considered to be associated with anticyclonic circulation. However, this study reveals that a previously underappreciated cyclonic-like...

Iron-Based Nanotechnology Empowers Sustainable Agriculture

Abstract Global food security faces mounting pressures from stagnating crop yields, widespread farmland degradation, frequent climate extremes, and nonpoint source pollution from unsustainable agriculture, creating an urgent demand for ecoefficient technologies to advance sustain...

Towards Optimal Speculative Decoding: A Comprehensive Survey on Optimizations and Future Directions

Speculative decoding (SD) has emerged as a compelling approach to breaking the sequential bottleneck of autoregressive large language model (LLM) inference. By coupling lightweight drafting with parallel verification, SD reduces expensive target-model decoding while preserving ge...

From Mirror to Autonomy to Self-Reference: Protocol-Level Markers of Autopoiesis in a Human–AI Coupled System

This paper presents a theory-generating case study of a human–AI coupled system over a 12-day window (six active days), inducing an operationalizable criterion (Criterion O) for observable markers of autopoiesis and committing to prospective classification pending an independent...

Life Cycle Assessment of Synergistic Technologies for Pollution and Carbon Reduction in Cotton Knitted Fabric Dyeing and Finishing: A Case Study of Zhejiang Province, China

The textile dyeing and printing (TDP) industry in Zhejiang Province faces significant pressure to reduce conventional pollutants and carbon emissions. Dyeing and finishing (DF) are key links in energy consumption and pollutant emissions in the TDP industry. However, the trade-off...

Model Test on Thermo-Mechanical Behavior of Pure Friction Piles Under Cyclic Temperature

Frictional energy piles are a more desirable form of shallow geothermal energy utilization. A pure friction pile condition cannot be achieved in field tests. In this study, foam was placed beneath the model pile tip to weaken the end-bearing resistance. The effects of different c...

Land marketization, fiscal decentralization and carbon emissions

During China’s period of economic transition, its policy of fiscal decentralization (FD) has vigorously promoted China’s economic development, but it has brought about a mass of carbon emissions (CE) from its urban and industrial development. To solve environmental problems, the...

Balancing Microplastic Retention and Wetland Sustainability: A Salinity-Dependent LBM Transport Model

Constructed wetlands (CWs) are widely used as an ecological technology for wastewater treatment. However, the accumulation of microplastics (MPs) in their substrates may impair long-term performance and threaten the operational sustainability of these nature-based treatment syste...

Experimental study and model prediction of acoustic wave dispersion and attenuation in medium-coarse sandy sediments

A comparable joint dataset of compressional-wave (P-wave) and shear-wave (S-wave) speed and attenuation for saturated Ottawa sand under consistent sample conditions was obtained, using a dual-probe acoustic measurement method (DPAMM) for P-waves (20–150 kHz) and bender element (B...

Effectiveness of Microbial Composite Strains in Reducing River Sediment

The accumulation of sediment in rivers and lakes can elevate riverbeds, leading to a reduction in river channel flood-carrying capacity, impairment of water conservancy project benefits, and destruction of aquatic ecosystems. Systematic dredging projects are required in the routi...

Multi-objective optimization for backpressure forming of thin-walled complex scrolls via a hybrid PSO-BPNN, NSGA-III, and TOPSIS framework

Backpressure forming is essential for precision forming of thin-walled complex scrolls by applying a controllable counter-pressure to regulate inhomogeneous material flow. However, the process involves strong thermo-mechanical coupling effects, and there exists a highly nonlinear...
