The Generating Mechanism and Suppression Measure of the ‘Wheel‐Rail’ Rolling Arc for Electrified Trains

High Voltage, Volume 11, Issue 2, Page 370-384, April 2026.
ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system. An insulated

Pantograph–Catenary Interaction Prediction Model Based on SCSA-RBF Network

Applied Sciences
As a traditional numerical simulation method for pantograph–catenary interaction research, the pantograph–catenary finite element model cannot be applied to the real-time monitoring of pantograph–catenary contact force, and the computational cost ...

On Stability of Second Order Pantograph Fractional Differential Equations in Weighted Banach Space

Fractal and Fractional, 2023
This work investigates a weighted Banach space second order pantograph fractional differential equation. The considered equation is of second order, expressed in terms of the Caputo–Hadamard fractional operator, and constructed in a general manner to ...

Scanner‐agnostic dynamic jaw motion generation from virtual static excursive records using open‐source Python‐based artificial intelligence (AI) interpolation

Journal of Prosthodontics, Volume 35, Issue 3, Page 407-413, March 2026.
Abstract This technique describes a scanner‐agnostic digital workflow for generating dynamic mandibular motion from static virtual interocclusal records using a custom artificial intelligence (AI) algorithm and user interface. Virtual records of mandibular positions, including maximum intercuspation, protrusion, and lateral excursions, were captured ...

Riemann-Liouville fractional-order pantograph differential equation constrained by nonlocal and weighted pantograph integral equations

AIMS Mathematics
In this research, we investigated the Riemann-Liouville fractional-order pantograph differential equation constrained by nonlocal and weighted pantograph integral constraints. We presented novel sufficient conditions for the uniqueness of the solution.

Heavy‐Haul Railway Alignment Design Considering the Heavy‐to‐Light Ratio and Regenerative Braking Energy

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study proposes an NSGA‐II framework enhanced with struct‐based encoding for bi‐objective optimization of heavy‐haul railway vertical alignment (construction cost and energy consumption), which requires no preset vertical points of intersection (VPIs) and inherently meets most constraints.
