Pronounced megafaunal community transition driven by polymetallic nodule cover in the Northwest Pacific abyss

Polymetallic nodules provide essential hard substrata for benthic fauna and are widely assumed to enhance biodiversity on abyssal plains. Yet, our understanding of how nodule cover shapes megafaunal communities remains limited and largely restricted to low nodule cover conditions...

Prediction of Joint Roughness Coefficient Using Metaheuristic-Optimized Random Forest Model

Reliable estimation of the joint roughness coefficient (JRC) is important for quantitative characterization of joint roughness and provides an important geometric parameter for subsequent joint shear strength assessment. However, single-parameter empirical models cannot fully cap...

Fluid–Structure Interaction Simulation of a Supersonic Reefed Parachute Cluster During the Inflation Process

To investigate the multi-stage inflation mechanism of a supersonic reefed parachute cluster, an ALE-based fluid–structure interaction method is applied. The canopy permeability is modeled using the Ergun equation, and the virtual structure contact method is employed to handle con...

Habitat-Associated Variation in Dietary Composition, Gut Microbiota, and Muscle Nutritional Characteristics of Hemibagrus guttatus in a Dam-Regulated River

Hydropower regulation can alter riverine habitats and potentially influence fish diet, gut microbiota, and nutritional characteristics. In this study, upstream and downstream populations of Hemibagrus guttatus (H. guttatus) were investigated in a dam-regulated reach of the Hongsh...

Learning to sail without wind information: reinforcement learning-based control for unmanned sailing vessels under partial observability

Unmanned sailing vessels commonly rely on real-time wind-field measurements as key inputs for multi-level decision-making, including path planning and control. During long-endurance offshore missions, however, wind-sensing systems may be affected by harsh environmental conditions...

Biomimetic Janus Eutectogels With Dynamic Compliance for High‐Fidelity Bioelectronic Interfaces

ABSTRACT The recording of high‐fidelity electrophysiological signals is the cornerstone of bioelectronics development. However, overcoming signal interference caused by motion artifacts and unintended adhesion during daily activities remains a challenge. This paper introduces a b...

Abstract 3D seismic data acquisition, processing, and analysis have become increasingly prevalent in modern geophysical exploration. However, various types of coherent noise, especially linear noise, can cause serious interference and effective noise reduction techniques are crit...

Buffering digital risk: the moderating role of education in the ICT–suicide mortality interface

The expansion of education and the rapid advancement of Information and Communication Technology (ICT) have fundamentally reshaped the socioeconomic determinants of mental health. However, the complex interplay between these two forces in shaping suicidal behavior remains underex...

Emerging nitrogen-driven urban atmosphere control on aerosol iron dissolution for biogeochemical cycles

Iron (Fe) is a critical micronutrient regulating marine productivity and the global carbon cycle, yet its atmospheric dissolution mechanisms remain debated for biogeochemical cycle. The prevailing “iron-sulfur coupling” paradigm has traditionally explained proton-promoted dissolu...

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

ABSTRACT Sexual fate in vertebrates is generally considered developmentally fixed; however, teleost fishes exhibit remarkable flexibility in their reproductive systems. It remains unclear whether a fully differentiated gonochoristic vertebrate can undergo complete and functional...

Physical Processing of Aquatic Gel Foods: From Protein Structure Regulation to Health, Sustainability, and Personalized Design

Aquatic gel foods, including surimi, minced crustacean products, and algal gels, are important platforms for aquatic protein valorization. However, their production is constrained by uneven thermal gelation, endogenous enzyme-driven deterioration, nutrient loss, additive dependen...
