Static Multi-Vortex Structures in Nonlinear Optical Media [PDF]
We demonstrate through numerical simulations the existence of a new type of nonlinear waves in optical media: structures of vortex solitons that remain static in certain configurations, which depend on their relative positions and topological charges ...

A Cost–Benefit Approach to Discuss Artificial Nourishments to Mitigate Coastal Erosion
Worldwide, artificial nourishments are being considered as one of the main coastal erosion mitigation measures. However, this solution is not permanent, since the natural removal of sediments that occurs after the sand deposition leads to the need of re ...
