Thermal EHL Characteristics Investigation on Axle Box Bearings of Railway Vehicle Based on Slicing Method

Shock and Vibration, 2019
Lubrication failures of axle box bearings can lead to accidents, such as bearing burnout and hot axle cutting. Presently, the modeling of the vehicle-track system dynamics rarely considers the nonlinear contact load of axle box bearings, and this leads ...

Intimate Spaces on the Open Road: Navigating Access, Trust, and Ethical Boundaries during Field Research with Long Haul Truck Drivers

Symbolic Interaction, EarlyView.
Despite its ubiquity, the trucking industry is not well‐understood in social scientific literature. Gathering insight into truckers' worlds is difficult due to the solitary, isolating, and unpredictable nature of the work. An understanding of truckers' work lives and work ideologies is even further limited.

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Containerized Truck Movements in Sweden Payload and Empty Trip Modeling

Transportation Journal, Volume 65, Issue 4, Autumn 2026.
ABSTRACT Container flows account for 12% of truck traffic in Sweden. Unlike other freight, container truck movements mostly involve import or export cargo that begins or ends at ports. However, containerized cargo has different payloads and empty trip patterns.

Scheduling optimization of optical lens polishing

International Transactions in Operational Research, Volume 33, Issue 6, Page 3744-3768, November 2026.
Abstract Optical systems have achieved notable progress in focusing and imaging technologies; however, manual grinding remains indispensable, resulting in elevated costs, extended timelines, and inefficiencies. These difficulties are compounded by operational constraints, uneven machine utilization, and risks of order delays and escalating expenses ...

Predicting Pavement Condition Index for Cold‐Region Highways Using an ENET‐XGBoost Coupled Model

Applied Research, Volume 5, Issue 5, October 2026.
An ENET–XGBoost framework combines regularized feature selection and nonlinear residual correction for cold‐region pavement prediction. Traffic loading dominates deterioration; the model achieved R2 = 0.969 in back‐calculation, while Markov and scenario analyses indicate a 25% risk of Fair‐or‐below condition in 2026 and PCI of 74.2–77.5 by 2028 ...

Mechanotransduction of Magnetically Applied Forces Leads to Mechanical Stiffening of Platelet‐Rich Plugs

Advanced Healthcare Materials, Volume 15, Issue 34, 11 September 2026.
A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)

‘Turnaround’ of Indian Railways: Increasing the Axle Loading [PDF]

Axle loading had contributed significantly to the ‘turnaround’ of the Indian Railways (IR) in the two years 2004-06. As the Minister of Railways (MR) stated, “A one ton extra loading per wagon implied additional revenue of Rs 500 crore per annum for IR.”
