Maize–soybean intercropping: A bibliometric analysis of 30 years of research publications
Abstract Maize (Zea may L.)–soybean [Glycine max (L.) Merr.] intercropping is popular in many countries because of its high productivity. However, no studies have explored maize–soybean intercropping via bibliometric methods. Taking the Web of Science database, the visualization applications of CiteSpace and VOSviewer were used to visually analyze the ...

Gapped vegetation patterns: crown/root allometry and snaking bifurcation [PDF]
Nonuniform spatial distributions of vegetation in scarce environments consist of either gaps, bands often called tiger bush or patches that can be either self-organized or spatially localized in space. When the level of aridity is increased, the uniform vegetation cover develops localized regions of lower biomass.

A Review of Vegetation Encroachment Detection in Power Transmission Lines using Optical Sensing Satellite Imagery [PDF]
Vegetation encroachment in power transmission lines can cause outages, which may result in severe impact on economic of power utilities companies as well as the consumer. Vegetation detection and monitoring along the power line corridor right-of-way (ROW) are implemented to protect power transmission lines from vegetation penetration.
