Predicting Performance of Hall Effect Ion Source Using Machine Learning
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

American Journal of Botany, EarlyView.Abstract Premise The origin of endemic species in the European Alps is commonly attributed to the climatic oscillations of the Quaternary. Moehringia sect. Moehringia, with 12 of 15 species endemic to the Alps and mostly restricted to well‐known glacial refugia, is a prime system for investigating the diversification of a lineage originating in the ...

American Journal of Community Psychology, EarlyView.Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

Australian Journal of Social Issues, EarlyView.ABSTRACT Robust measurement of disadvantage is essential to identifying and addressing inequities in children's development. We tested how a multidimensional framework of child disadvantage performed relative to a traditional socioeconomic position (SEP) approach to predict developmental outcomes.
