Fertilization can accelerate the pace of soil microbial community response to rest‐grazing duration in the three‐river source region of China

Ecology and Evolution, 2023
Overgrazing leads to grassland degradation and productivity decline. Rest‐grazing during the regreen‐up period can quickly restore grassland and fertilization is a common restoration strategy.

Interaction in Assistive Robotics: A Radical Constructivist Design Framework

Frontiers in Neurorobotics, 2021
Despite decades of research, muscle-based control of assistive devices (myocontrol) is still unreliable; for instance upper-limb prostheses, each year more and more dexterous and human-like, still provide hardly enough functionality to justify their cost

A Solar Photovoltaic Performance and Financial Modeling Solution for Grid-Connected Homes in Zambia

International Journal of Photoenergy, 2021
Zambia is today 90% hydropower dependent, but this may change because Zambia and the World at large are today facing a changing climate that affects the ecosystem, rain patterns, and spurs drought which reduces the production of hydropower.
