Abstract There are no theoretical formulas that can accurately predict the sand transport rate (Qm) over the Gobi surface. We report herein high‐frequency field observations of wind‐blown sand processes over the Gobi surface under extremely high winds in eastern Xinjiang, China. The results reveal that the power‐law exponent of the scaling relationship

Supply chain risk in grain trading: Inventories as real options for shipping grain
Abstract Integrating trading and logistics is an important challenge in commodity trading. Trading and logistics are strategic decisions and are integral to most commodities including grain shipping by rail, in addition to other modes (barges, ocean shipping). There are substantial risks, such as the ordering and placement of rail cars.

The Role of Campus as an Urban Multiuse Protected Area in Bird Nocturnal Roosting Habitat Function
Campus green spaces are essential for providing critical nocturnal habitats, playing a key role in supporting urban bird species in fragmented environments. Seasonal variations significantly influence nocturnal bird roosting site selection, with birds adapting their roosting patterns to changing environmental conditions throughout the year.
