In this paper, a new kind of hierarchical tube with a negative Poisson's ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb. Then, the second level tube is produced by substituting the arm of the auxetic sheet with the first level tube and rolling it up. The Nth ( ) level tube can be built recursively. Based on the Euler beam theory, the eq...

In 2010, Anderson, Craciun, and Kurtz showed that if a deterministically modeled reaction network is complex balanced, then the associated stochastic model admits a stationary distribution that is a product of Poissons [5]. That work spurred a number of followup analyses. In 2015, Anderson, Craciun, Gopalkrishnan, and Wiuf considered a particular scaling limit of the stationary distribution det...

Côte d’Ivoire had a strong industrial fleet both in capacity and reach. Despite the decline of the sector, the country still held a particular place within West Africa due to its harbour and shore facilities, which have made Abidjan the second most important fishing port in the region. Its industrial fleets returned to the waters of Côte d’Ivoire after West African countries declared their EEZs...
