Cryptic Diversity in Colombian Edible Leaf-Cutting Ants (Hymenoptera: Formicidae)

open access: yesInsects, 2018
Leaf-cutting ants are often considered agricultural pests, but they can also benefit local people and serve important roles in ecosystems. Throughout their distribution, winged reproductive queens of leaf-cutting ants in the genus Atta Fabricius, 1804 ...

Phase Modulation of Retro-Reflected Radar Echo Signal Using a Microstrip Van-Atta Array

open access: yesIEEE Access, 2019
Van-atta array is able to retro-reflect the incident signal back to the income direction and, thus, it can maintain a relatively larger radar cross-section (RCS) in a large range of incidence angles.

Genome-wide analysis of heavy metal ATPases (HMAs) in Poaceae species and their potential role against copper stress in Triticum aestivum

open access: yesScientific Reports, 2023
Plants require copper for normal growth and development and have evolved an efficient system for copper management based on transport proteins such as P1B-ATPases, also known as heavy metal ATPases (HMAs). Here, we report HMAs in eleven different Poaceae
