Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

open access: yesWind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

Engineering Layered Magnetic Hydrogels for Cell Placement via Shear and Magnetic Field‐Induced Assembly

open access: yesAdvanced Materials, Volume 38, Issue 44, 7 August 2026.
Magnetic particles are organized into layered architectures by combining shear flow and magnetic fields, with the resulting structures governed by appropriate Mason numbers. The programmed assemblies provide spatial guidance for cell placement, linking field‐controlled self‐assembly, flow‐induced structuring and biological organization.

Simulation modeling of the Adjustable Buoyancy Device for open ocean low trophic aquaculture, part I: Test of a submersible long tube unit

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Open‐water low‐trophic aquaculture (LTA) is a sustainable method for producing ocean‐based food and providing ecosystem services. An effective system design is critical for mitigating risks posed by deep ocean forces. Developing submersible cultivation technology requires quantitative risk analysis and modeling to address offshore challenges ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too
