Bridging Efficiency Gaps in Rice Production: A Primal System Analysis of Technical and Allocative Constraints in Bangladesh

Sustainable Development, EarlyView.
ABSTRACT Declining natural resources, rising production costs, and diminishing returns from input‐intensive practices threaten the sustainability of smallholder rice systems in Bangladesh. Using a primal system approach and survey data from 1869 rice‐producing households, this study evaluates technical and allocative inefficiency across major agro ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Reconstructing Old Chinese *‐ts Using Han‐Time Material

Transactions of the Philological Society, EarlyView.
Abstract Baxter & Sagart (2014b) reconstruct *‐Vt‐s on the basis of Middle Chinese reflexes in ‐jH (from some OC *‐s) coupled with either etymological or graphic connections to words in Middle Chinese ‐t. This approach, while perfectly sound, can suffer from lack of etymological or graphic data, leading to missed reconstructions. Since Old Chinese *‐ts
