Lie-group variational integrators of arbitrary order are developed using the Galerkin method, based on unit quaternion interpolation. To our knowledge, quaternions have not been used before for this purpose, though they allow a very simple and effici

We present a Galerkin multisymplectic Lie group variational integrator. It is suitable for dynamical systems defined on a two dimensional space–time and the integrator allows arbitrary convergence orders independently for both dimensions. As an exa

SUMMARY With the rapid increase of the quantity of molecular data, many animals joined the ranks of the so-called ‘emerging models’ of Evo-Devo. One of the necessary steps in converting an emerging model into an established one is gaining compreh

Apoptosis is a highly conserved mechanism of cell deletion that destroys redundant, dysfunctional, damaged, and diseased cells. Furthermore, apoptotic cell death is essential during the development of multicellular organisms. However, there are only

In planula larvae of the invertebrate Hydractinia echinata (Cnidaria, Hydrozoa), peptides of the GLWamide and the RFamide families are expressed in distinct subpopulations of neurons, distributed in a typical spatial pattern through the larval body.

Cnidaria are one of the basal groups within the metazoans. They are divided into the Medusozoa (Hydrozoa, Scyphozoa, Staurozoa, and Cubozoa) and the Anthozoa, which are thought to be the basal group within the Cnidaria. Cnidaria together with the Cte

The free-living stages of sedentary organisms are an adaptation that enables immobile species to exploit scattered or transient ecological niches. In the Cnidaria the task of prospecting for and identifying a congenial habitat is consigned to tiny pl

For the elastodynamic simulation of a geometrically exact beam [1], an asynchronous variational integrator (AVI) [2] is derived from a PDE viewpoint. Variational integrators are symplectic and conserve discrete momentum maps and since the presented i
