<p>Abstract</p> <p>Background</p> <p>Owing to its independence from the main Central European drainage systems, the Italian freshwater fauna is characterized by a high degree of endemicity. Three main ichthyogeographic districts have been proposed in Italy. Yet, the validity of these regions has not been confirmed by phylogenetic and population genetic analyses and a phylogeographic scenario for Italy's primary freshwater fish fauna is still lacking. Here, we investigate the phylogeography of th...

When an Autonomous Underwater Vehicle(AUV) sails near the surface of the sea,it will inevitably be subjected to wave disturbance. The heave and pitch motion caused by wave disturbance not only affects the navigation attitude of the AUV,but also leads to an increase in sailing resistance. As such, its energy consumption is increased. In this paper,the six degrees of freedom model of AUVs is established and linearized in order to achieve the weighted optimization of the sailing attitude and the re...
