Global Policy, EarlyView.ABSTRACT This paper critically examines the conceptual overstretch of weaponized interdependence (WI) in analyses of China's dominance over lithium and rare‐earth element (REE) markets. Although WI has become a central framework for interpreting EU–China economic relations, its application to raw materials often extends beyond the theory's original ...

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.Abstract Kentucky producers have sought to add industrial hemp (Cannabis sativa L.) for grain, fiber, and/or floral material to their cropping systems since hemp's legalization in the 2018 Farm Bill. This study sought to quantify hemp's impact on ecosystem services provisioned by the traditional corn (Zea mays L.)–soybean (Glycine max (L.) Merr ...

LES evaluation of the effects of equivalence ratio fluctuations on the dynamic flame response in a real gas turbine combustion chamber [PDF]
, 2013 Large Eddy Simulations (LES) of a lean swirl-stabilized gas turbine burner are used to analyze mechanisms triggering combustion instabilities. To separately study the effect of velocity and equivalence ratio fluctuations, two LES of the same geometry are

Tracing the Untraceable: A Review and Discussion on the Forensic Attribution of 3D‐Printed Firearms
WIREs Forensic Science, Volume 8, Issue 4, December 2026.3D‐printed firearms are rapidly evolving and challenge traditional forensic identification. This review highlights emerging attribution methods, from deposition striae and base‐plate marks to polymer and GSR residual traces, firing marks, and quantitative imaging, identifying the research needed to support robust forensic attribution interpretation and
