We are able to compute the Grobner basis and Markov basis of the toric ideal of invariants for trees with up to 11 nodes. ...
We consider the phylogenetic tree model in which every node of the tree is observed and binary and the transitions are given by the same matrix on each edge of the tree. ...
Knowledge of the generators would allow us to easily compute whether given data came from the homogeneous Markov model from some specific phylogenetic tree. ...

To simulate these flows by applying homogeneous models, an appropriate equation of state (EOS) is necessary to cover all possible fluid states (pure liquid, two-phase mixture and pure vapour). ...
The simulation of cavitating flows is a challenging problem both in terms of modelling the physics and developing robust numerical methodologies. ...
They are implemented using different approaches: the one-fluid method or homogeneous model, the two-fluid method and the hybrid method. ...

The effective mechanical properties of these auxetic structures have been computed in the framework of couple stress elasticity, allowing to identify both in-plane and out-of plane effective properties ...
The auxetic nature of the computed microstructures is demonstrated by both numerical and real experiments performed over samples fabricated by additive printing. ...
Based on the previous auxetic homogenized properties (e.g., a 1 × 1 cell), we will quantify the effects of the couple stress model on the macroscopic scale by evaluating the response of a macrobeam subjected ...
