Mix Proportion of Fly Ash Concrete Based on the Strength Contribution Ratio
ABSTRACT This study aims to expand the use of fly ash concrete (FAC). Based on an experimental investigation of k values or the contribution of FA addition to the strength of ordinary Portland cement or Portland blast‐furnace slag cement type B, we propose and validate an environmentally friendly mix design for FAC.

Multi‐Resolution Deep Learning for Coupler Force Prediction in 20,000‐Ton Heavy‐Haul Trains
This study presents a deep learning framework for predicting coupler forces in 20,000‐ton heavy‐haul trains using simulation‐generated datasets. A novel multi‐resolution dual‐stream LSTM (MRDS‐LSTM) model captures both short‐ and long‐term temporal features, outperforming representative baselines such as RNN, GRU, LSTM, Bi‐LSTM, and CNN‐LSTM.
