Experimental settlement and dynamic behavior of a portion of ballasted railway track under high speed trains [PDF]

, 2008
International audienceThe study of railway tracks under high speed trains is one of the most important researches in the domain of transport. A reduced scale experiment with three sleepers is presented to study the dynamic behavior and the settlement of ...

Exploring Lived Experiences of Men Diagnosed With Prostate Cancer in Oman: A Qualitative Study

Health Expectations, Volume 29, Issue 3, June 2026.
ABSTRACT Background Life after prostate cancer treatment may extend across decades; however, qualitative evidence describing how men in Oman navigate treatment sequelae, disclosure, family involvement, and religious coping remains limited. This study explored the lived experiences of Omani men who had completed primary therapy for prostate cancer ...

Scoping assessment of free-field vibrations due to railway traffic [PDF]

, 2018
The number of railway lines both operational and under construction is growing rapidly, leading to an increase in the number of buildings adversely affected by ground-borne vibration (e.g. shaking and indoor noise).

A 2.5D coupled FE-BE model for the prediction of railway induced vibrations [PDF]

, 2010
Ground vibrations induced by railway traffic at grade and in tunnels are often studied by means of two-and-half dimensional (2.5D) models that are based on a Fourier transform of the coordinate in the longitudinal direction of the track.

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, Volume 43, Issue 3, Page 1861-1870, May 2026.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Investigating the Influence of Auxiliary Rails on Dynamic Behavior of Railway Transition Zone by a 3D Train-Track Interaction Model

Latin American Journal of Solids and Structures
Abrupt track vertical stiffness variations along railway tracks can lead to increased dynamic loads, asymmetric deformations, damaged track components, and consequently, increased maintenance costs.

Dynamic Comparison of Conventional Ballasted Track Versus Ballasted Ladder Track

, 2015
In railway transport system there is a continuous demand for railway capacity enhancement. In order to meet the demands in many countries more axle load and higher speed of the train is applied. As a result of these the track responses are becoming big issues that have a great effect on track service. Therefore to develop and utilize appropriate tracks

On the Efficiency and Durability of Purposefully Sinking Seaweed Biomass as a Marine Carbon Dioxide Removal Strategy

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Large‐scale farming and purposeful sinking of seaweed has been suggested as a marine Carbon Dioxide Removal (mCDR) strategy. Farmed seaweed uptakes dissolved inorganic carbon (DIC) from the mixed layer, resulting in a CO2 deficit that causes an influx of atmospheric CO2 into the surface ocean.

Track Bed Gaps Impact on Ballast Particle Surrounding Flow Field and Aerodynamic Forces for High-speed Railways before and after Ballast Splashing

Chengshi guidao jiaotong yanjiu
[Objective] When high-speed trains operate on ballasted tracks, the complex airflow field around ballast particles can lead to track ballast splashing. The formation mechanism of this phenomenon remains unclear.
