Estimation of Change Points for Non‐Linear (Auto‐)Regressive Processes Using Neural Network Functions

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT In this paper, we propose a new test for the detection of a change in a non‐linear (auto‐)regressive time series as well as a corresponding estimator for the unknown time point of the change. To this end, we consider an at‐most‐one‐change model and approximate the unknown (auto‐)regression function by a neural network with one hidden layer. It

Sustainability Assessment of Alternative Methods for Destruction of Per‐ and Polyfluoroalkyl Substances (PFAS) in Water

open access: yesRemediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the
