Integrated Design and Process Optimization of FDM‐Fabricated Hexagonal Architected Thin‐Walled PA12 Tubes for Improved Compressive and Energy Absorption Performance

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
FDM‐fabricated PA12 thin‐walled tubes with five hexagonal architected designs (D1–D5) of increasing nodal connectivity were investigated to determine the effects of wall architecture, layer height, and print angle orientation on compressive performance, energy absorption, and dimensional accuracy.

A Heavy-Haul Railway Corrugation Diagnosis Method Based on WPD-ASTFT and SVM

Shock and Vibration, 2022
Rail corrugation in heavy-haul railway increases the contact forces between the wheel and the rail and deteriorates the rail condition. Severe corrugation affects railway operational safety.

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2648-2669, 10 April 2026.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Ultralight Conductive MXene Aerogels: From Material Design to Energy, Environment, and Electronic Applications

Small Science, Volume 6, Issue 4, April 2026.
MXene aerogels combine the intrinsic conductivity and surface chemistry of MXenes with ultralight, highly porous 3D architectures, enabling efficient charge/heat transport and multifunctional performance. By tailoring pore structure, orientation, surface functional groups, and hybrid compositions (with polymers, carbons, metals, and MOFs), MXene ...

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Rail Corrugation Detection of High-Speed Railway Using Wheel Dynamic Responses

Shock and Vibration, 2019
Rail corrugation often occurs on the high-speed railway, which will affect ride comfort and even the train operation safety in severe condition. Detection of rail corrugation wavelength and depth is absolutely essential for maintenance and safety.

Contributions of early and late cover provision to the abundance and diversity of invertebrate prey for Corncrakes (Crex crex)

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Early and late cover (ELC) provides important habitat for ground‐dwelling invertebrates and significantly increases the abundance of Corncrake prey during key stages of the breeding season. Using mixed models, we show that ELC supports higher prey abundance than unmanaged natural regeneration cover and surrounding farmland.
