An Ensemble Machine Learning Method for Alkali‐Activated Concrete Mix Ratio Analysis and Optimizing Experimental Results

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
In this study, we discovered a combined learning algorithm of MLP–RF for predicting the composition of concrete and achieved favorable results in the inversion experiment. ABSTRACT In the field of civil engineering, the analysis of the composition of alkali‐sprayed concrete is of great significance for material research. However, there are currently no

Threshold MIDAS Forecasting of Canadian Inflation Rate

open access: yesJournal of Forecasting, Volume 45, Issue 2, Page 749-769, March 2026.
ABSTRACT We propose several threshold mixed data sampling (TMIDAS) autoregressive models to forecast the Canadian inflation rate using predictors observed at different frequencies. These models take two low‐frequency variables and a high‐frequency index as threshold variables.

Neural Representations of Death‐Related Concepts Identify Conceptual Alteration of Self in Suicidal Youth

open access: yesHuman Brain Mapping, Volume 47, Issue 4, March 2026.
The neural representations of death‐related concepts like death or funeral are altered in suicidal ideators. Compared to Healthy Control participants (shown in red), suicidal ideators show higher levels of activation (in green) in regions previously identified as being related to self‐reflection when they think about death‐related concepts (yellow ...
