Integrating functional traits and carbon partitioning to productivity and adaptive resilience in bamboo clones for climate change mitigation: a trait-based approach

Frontiers in Ecology and Evolution
Bamboo is a key component of nature-based solutions for carbon sequestration and climate change mitigation. However, clone- or species-specific mechanisms regulating biomass production, carbon allocation, and adaptive resilience under changing climatic ...

Convergence of Iterative Descent Algorithms for LEO-PNT

IEEE Access
Abstract: Positioning Navigation and Timing (PNT) from Low Earth Orbit (LEO) has been gaining momentum in the last couple of years. LEO-PNT can serve as an alternative to current Global Navigation Satellite Systems (GNSS) or as an addition to the current system using a multi-layer approach.

Resilience of the PNT Systems

, 2017
There is a high national dependency on Position, Navigation and Timing (PNT) Systems for several individuals, services and organisations that depend on this information on a daily basis. Those who rely on precise, accurate and continuous information need to have resilient systems in order to be highly efficient and reliable.
