Entangled Foodways and Livelihood Pathways: Cinnamon, State Interventions, and Everyday Life in Hmong Communities of Northern Vietnam

Journal of Agrarian Change, EarlyView.
ABSTRACT The agroecological practices of ethnic minority farmers in Vietnam's northern uplands are being reshaped by intersecting pressures of land‐use reform, market integration, and state‐backed crop promotion. Among Hmong communities in the south of Lào Cai Province (former Yên Bái Province) cinnamon was once valued primarily for its medicinal ...

Ordering Phenomena on Growing Films

, 1998
In many growth processes particles are highly mobile in an active layer at the surface, but are relatively immobile once incorporated in the bulk. We study models in which atoms are allowed to interact, equilibrate, and order on the surface, but are ...

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 8, Page 1694-1709, 10 July 2026.
ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Radiative Magnetic Reconnection in Astrophysics

, 2015
I review a new rapidly growing area of high-energy plasma astrophysics --- radiative magnetic reconnection, i.e., a reconnection regime where radiation reaction influences reconnection dynamics, energetics, and nonthermal particle acceleration.
