Evaluating nitrogen cycling in terrestrial biosphere models: A disconnect...
Terrestrial carbon (C) sequestration is limited by nitrogen (N), an empirically established constraint that could intensify under CO2 fertilization and future global change. The...- publication PDF

Are all flare ribbons simply connected to the corona?
We consider the observational basis for the belief that flare ribbons in the chromosphere result from energy transport from the overlying corona. We study ribbons of small...- publication PDF
