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

Earthquake 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

Hairy, hairy quite contrary: Pollination and functional floral traits in a hirsute carrion‐scented stapeliad

TAXON, Volume 75, Issue 3, June 2026.
Abstract Floral mimicry of decaying substrates of animal origin, such as carrion or faeces, is associated with unusual traits such as geoflory, deep maroon or yellow colouration, floral hairs and unpleasant odour, but the functional significance of these traits for attracting and manipulating pollinators has seldom been examined.

A Magnetic Field Concentration Method for Magnetic Flux Leakage Detection of Rail-Top Surface Cracks

IEEE Access
Magnetic Field Leakage (MFL) is one of the prominent methods used to detect rail top surface cracks. However, it has been shown that detecting narrow rail top cracks is a major challenge because of their weak magnetic leakage fields.

A Preliminary Study on 2D Convolutional Neural Network-Based Discontinuous Rail Position Classification for Detection on Rail Breaks Using Distributed Acoustic Sensing Data

IET Electrical Systems in Transportation
Rail breaks, which are crucial maintenance issues for the railways, require immediate inspection and maintenance as it can cause severe railway accidents. Though, it is still difficult to promptly detect rail breaks that occur during train operation even
