A new study leveraging 20,000 tree-ring records and nearly 150 scientists' contributions from across the globe shows that, while droughts appear to have had a modest impact on tropical tree growth in ...

Abstract: The rapid expansion of Low Earth Orbit (LEO) satellite constellations presents new challenges for maintaining efficient inter-satellite communication under dynamic network topologies.

Breakdown of the working principle. Humans are naturally confident in using time to model events, and in graph problems, each edge has a weight. As inspired by JavaScript's event loop, this weight can ...
