Spatiotemporal changes in soil chemical properties when cover crops are integrated into raised, stale seedbed corn production systems

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Commercial row crop production in the midsouthern United States is characterized by extensive application of inorganic soil inputs and management practices that contribute to degraded soil health. This study was conducted to determine if cover crops affect spatial or temporal changes in soil chemical properties in a raised, stale seedbed ...

The effect of compliance assistance on pollution discharges and violations of environmental regulations

open access: yesJournal of Policy Analysis and Management, Volume 45, Issue 3, Summer 2026.
Abstract Researchers and policymakers assert competing behavioral models of polluters. One model portrays polluters as best approximated by the perfectly informed, rational actor from economics textbooks. Another model portrays polluters, particularly small and medium facilities, as imperfectly informed, cognitively bounded, pro‐social actors.

Time‐Adaptive HénonNets for Separable Hamiltonian Systems

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Measurement data is often sampled irregularly, i.e., not on equidistant time grids. This is also true for Hamiltonian systems. However, existing machine learning methods, which learn symplectic integrators, such as SympNets and HénonNets still require training data generated by fixed step sizes.

Negotiating Global Citizenship and Nationalism: Shifting Paradigms in Hong Kong's Global Citizenship Education

open access: yesEuropean Journal of Education, Volume 61, Issue 2, June 2026.
ABSTRACT This conceptual paper critically examines the evolving interplay between global citizenship and nationalism in Hong Kong's global citizenship education. Drawing on critical analysis of existing literature and recent socio‐political and educational changes in Hong Kong, it traces the shift from a Western‐oriented global citizenship ...

PID‐Like Robust Control of Non‐Minimum Phase Robotic Manipulators

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 8, Page 4490-4503, 25 May 2026.
ABSTRACT This paper proposes an output‐feedback tracking controller for non‐minimum phase nonlinear systems with unknown uncertainties and external disturbances, where not all states are measurable, and the zero dynamics are unstable. The approach combines a backstepping‐based stabilizing state‐feedback law with a cascade extended high‐gain observer ...
