Gradient and divergence are the basis of electromagnetic field theory, and have been a special difficulty in mathematical theory. Understanding these concepts requires strong spatial and abstract ...

Polygonum pensylvanicum and Abutilon theophrasti, components of old-field communities in central Illinois were grown on a controlled soil moisture gradient to determine whether they exhibit different ...

• Background and Aims The dwarf shrub Cassiope tetragona (Arctic bell-heather) is increasingly used for climate reconstructions, the reliability of which depends on the existence of a linear ...

Abstract: Electromagneto-quasistatic (EMQS) field formulations model resistive, capacitive, and inductive effects, while disregarding wave propagation. When such formulations are expressed in terms of ...

To better understand the triggering mechanisms of extreme precipitation events in Central Asia due to the complex terrain, a case study of a topographic blizzard that occurred in Xinjiang Province on ...
