Assessing Post‐Earthquake Emergency Healthcare Accessibility Considering Damage to Hospital Buildings and Transportation Infrastructure

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article presents a framework for performing a regional assessment of the accessibility of emergency healthcare facilities after a major earthquake. Accessibility is assessed by applying the enhanced two‐step floating catchment area method to a regional road network, implemented in ArcGIS.

Research on the Dynamic Response Characteristics of a Railway Vehicle Under Curved Braking Conditions

Vehicles
When a railway train runs along a curved track with braking, the dynamic behaviors of the vehicle are extremely complex and difficult to accurately reveal due to the coupling effects between the wheel–rail interactions and the disc–pad frictions ...

Study on the improvement of semi-Hertzian wheel/rail contact algorithms

Journal of Traffic and Transportation Engineering (English ed. Online)
The normal stress distribution of the contact patch is the base for wheel/rail dynamic analysis as well as the wheel wear calculation. When the wheel polygonalization appears on the worn-type wheel tread of the high-speed trains, the lateral and ...

Pressurized Solid Oxide Electrolysis—Operational Strategies

Fuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT Pressurized high‐temperature electrolysis is a promising pathway for high‐efficiency hydrogen production that enables direct compression and heat recovery opportunities not accessible to low‐temperature electrolysis. While laboratory testing is routinely conducted near atmospheric pressure, there is increasing interest in commercial deployment

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 ...

Supply Chain Disruptions and Retail & Wholesale Inventory Dynamics: An Empirical Investigation

Transportation Journal, Volume 65, Issue 2, Spring 2026.
ABSTRACT Effective inventory management is critical for retail and wholesale (R&W) firms. Yet, little is understood regarding R&W firm‐level inventory dynamics during supply chain disruptions. Such dynamics have implications for transportation providers tasked with hauling these goods.
