Three-dimensional MHD simulations of interplanetary rotational discontinuities impacting the Earth's bow shock and magnetosheath
(2020-06-30)
The first ever fully three-dimensional magnetohydrodynamic (MHD) simulations of the detailed effects of MHD discontinuities on the magnetosheath have been performed. The simulation results predict that the interaction ...
Tracking transmission of apicomplexan symbionts in diverse Caribbean corals
(2019-05-10)
Symbionts in each generation are transmitted to new host individuals either vertically (parent to offspring), horizontally (from exogenous sources), or a combination of both. Scleractinian corals make an excellent study ...
TRANSIENT SCATTERING FROM DIELECTRIC CYLINDERS - E-FIELD, H-FIELD, AND COMBINED FIELD SOLUTIONS
(2022-10-05)
In this work, the problem of transient scattering by arbitrarily shaped two-dimensional dielectric cylinders is solved using the marching-on-in-time technique. The dielectric problem is approached via the equivalence ...
