This paper rigorously analyses preconditioners for the time-harmonic Maxwell equations with absorption, where the PDE is discretised using curl-conforming finite-element methods of fixed, arbitrary ...

A salt used to create a green rocket fuel is known to decompose metals—such as those in metal propellant storage tanks. Recent research at the University of Illinois Urbana-Champaign found that there ...

Aims Improvement cutting or harvesting can change the coverage of understory vegetation, which can significantly influence the litter decomposition process in plantations. However, difference in ...
