Integrated location–inventory planning for slow‐moving demands with waiting time limitations

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper studies a stochastic facility location problem integrated with inventory and transportation decisions (SFLPIT) for supply chains with slow‐moving stock‐keeping units (SKUs). Local stores often avoid maintaining such SKUs, resulting in customer demand being fulfilled directly by a central distribution center (DC), where the ...

U.S.‐China Tensions and Macroeconomic Fluctuations

open access: yesThe Manchester School, EarlyView.
ABSTRACT Business cycles and macroeconomic fluctuations are influenced by various factors. This paper analyzes the impact of the U.S.‐China Tension Index (UCT) on macroeconomic fluctuations in 32 countries using time series models from January 1999 to February 2024. The VAR model reveals that UCT shocks generate financial volatility and fluctuations in

Exploring the Time–Frequency Quantile Nexus Between SDG 9 and SDG 10 in Latin American Countries

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
This study examines the dynamic nexus between SDG 9 (Industry, Innovation, and Infrastructure) and SDG 10 (Reduced Inequalities) across Latin America using quarterly data and wavelet quantile techniques. Findings reveal a strong bidirectional relationship across different quantiles and time horizons, intensifying during economic reforms and policy ...

Trusting Machine Learning With Physics: A Fidelity Verification Framework for Complex Systems

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 6, December 2026.
Abstract Neural networks (NN) are embraced to model complex systems based only on data, but their opacity remains a concern. It is unclear whether skill comes from learning physical dependencies or data memorization, which could lead to catastrophic errors.

PARAMETER IDENTIFICATION FOR NONSTATIONARY NONLINEAR SYSTEMS

open access: yesPARAMETER IDENTIFICATION FOR NONSTATIONARY NONLINEAR SYSTEMS
In this paper, a method is presented for modelling a class of nonlinear systems which involves time-varying parameters. The system model proposed here is a type of nonlinear difference equation, where unknown parameters are assumed to be linearly involved in the system model.

Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

open access: yesReviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...
