Evaluation of the effect of wheel tread condition on the dynamic response of PC sleepers

Nihon Kikai Gakkai ronbunshu
Prestressed concrete sleepers (PC sleepers) are an important component of railway tracks. The dynamic response of PC sleepers to passing trains is influenced by various factors relating to the vehicles and tracks. However, few studies have quantitatively

Exposure to long-term source-specific transportation noise and incident breast cancer: A pooled study of eight Nordic cohorts

Environment International, 2023
Background: Environmental noise is an important environmental exposure that can affect health. An association between transportation noise and breast cancer incidence has been suggested, although current evidence is limited.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

Advanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Vibration of railway bridges in the audible frequency range

, 2009
The noise level associated with a train travelling on a bridge is normally greater than that for a train travelling on plain track. It is sometimes the bridge noise that causes the highest levels of disturbance to people in the vicinity or triggers ...

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...
