Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Predicting Performance of Hall Effect Ion Source Using Machine Learning

open access: yesAdvanced 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 ...

Matrimid‐Derived Asymmetric Carbon Molecular Sieve Hollow Fibers With Engineered Ultramicropores for Precise Helium Separation

open access: yesAngewandte Chemie, EarlyView.
Matrimid‐derived asymmetric carbon molecular sieve (CMS) hollow fibers enable ultraselective helium/methane (He/CH4) separation. Post‐pyrolysis hyperaging selectively tightens larger ultramicropores, enhancing He/CH4 discrimination while maintaining high He permeance.

A spatial signature of sprawl: or the proportion and distribution of linear networkcircuits [PDF]

open access: yes, 2005
This paper sets out to investigate whether the frequency distribution ofthe linear network circuits within a graph-based representation of aroad transportation system can be helpful in identifying sprawl and, inparticular, whether a 'spatial signature of

A Population‐Based Assessment of Cancer Risk in Children With VACTERL

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cancer risk in children with VACTERL, a nonrandom co‐occurrence of ≥ 3 defects (vertebral, anal, cardiac, tracheoesophogeal fistula, renal, and limb), remains unclear. We evaluated this association in a population‐based study. We analyzed data from the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Study, a US registry linkage ...
