Shape matters: Body dynamics underlies efficient jumping
Marc Suñé, Lucas Selva, Cristóbal Arratia +2
Many small animals, particularly insects, use power-amplification to generate rapid motions, such as jumping, that would otherwise be impossible given the standard power density of…

The destabilizing effect of particle concentration in inclined settlers
Cristian Reyes, Cristobal Arratia, Christian Ihle
Water scarcity has required constant water recycling, leading to a decline in water quality, further exacerbated by high concentrations of fine particles that reduce the efficiency…

Structure Preserving Restarts of the Non-Symmetric Lanczos Algorithm via the Implicitly shifted LR algorithm
Prabal S. Negi, Cristobal Arratia
The implicitly shifted QR iteration is used as a restart procedure for the Arnoldi method for the calculation of a few dominant eigenvalues of a large matrix. We show that the unde…
