The stability (measured using matrix correlations) of phenetic classifications based on partitions of continuous morphometric data (skeletal measurements from three groups of birds) was compared for ...

In this paper, we propose a new transformation of circular random variables based on circular distribution functions, which we shall call inverse distribution function (idf) transformation. We show ...

In spite of their simple description in terms of rotations or symplectic transformations in phase space, quadratic Hamiltonians such as those modelling the most common Gaussian operations on bosonic ...
