Electronic‐Structure Control of Ferromagnetism in Fe3GeTe2 and Fe3GaTe2: A Short Review

open access: yesAdvanced Physics Research, EarlyView.
Fe3GeTe2 and Fe3GaTe2 form a revealing materials pair for examining how carrier filling, orbital hybridization, magnetic anisotropy, and defects cooperate in metallic van der Waals ferromagnets. This Short Review interprets Ga substitution as chemical electronic‐structure engineering rather than simple rigid‐band doping and identifies decisive ...

Comparison of the technical performance of a discretely supported slab track system and an embedded slab track system in a high-speed railway [PDF]

open access: yes, 2019
Slab tracks are increasingly used for High-Speed Railways (HSR) as opposed to the conventional ballasted track. This is due to many factors, including increased durability and sustainability, as the slab track can sustain higher dynamic loading with less

Assessment of Track Quality in Trial Test Sections by Spot and Continuous Method

open access: yes, 2015
The quality of track alignment and track geometry is an essential precondition of safe and economical operation of railway track. The paper provides an analysis of diagnostics of relative track geometry parameters and evaluation of measurement deviations

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Cross-sectional temperature analysis method of slab track based on detailed evaluation of solar radiation and long-wave radiation

open access: yesNihon Kikai Gakkai ronbunshu
In some slab tracks in cold regions, freeze-thaw cycle causes frost damage to the slab track filling layer. To evaluate this phenomenon, we proposed a weakly coupled analysis method of heat balance calculation on the slab track surface and heat ...

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Experimental study on the dynamic characteristics of slab track structure considering local defects and temperature gradient

open access: yesCase Studies in Construction Materials
The unit slab track structure has been widely used in high-speed railways. Temperature gradients and local defects alter the interlayer condition of slab tracks, directly affecting the structure's dynamic performance.

Vibration properties of slab track installed on a viaduct

open access: yes, 2014
A model of the vibration behaviour of a discontinuous slab track installed on a viaduct is presented. It is represented by a three-layer Euler–Bernoulli beam model subjected to a harmonic load. Analytical equations are derived using the receptance method,

Sport, Agency and Pigeon Snaring in the Ancient Tongan Chiefdom

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Pigeon snaring was an élite sport in the traditional Tongan chiefdom, undertaken on purpose‐built mounds known as sia heu lupe. LiDAR imagery combined with field survey and mound documentation on the island of Tongatapu has identified a comprehensive corpus of these sites.

An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.
