A new urothripine species, Baenothrips cuneatussp. n., is described from China. This is distinguished from its congeners by the following combination of characteristics: dorsal surface of head having a wedge-shaped reticulation extending from median to the posterior margin; antennal segments VII-VIII is closely joined with a complete suture; the mesoacrotergite strongly constricted in the middl...

Haliclona is one of the most species-rich genera among Demospongiae, but with only 11 species recorded for the Brazilian coast. Here we describe two new species of Haliclona collected by trawling at Sergipe State (Northeastern Brazil). Haliclona (Halichoclona) dura sp. nov. is distinguished by the combination of confused choanosome with dense reticulation, oxeas with stepped and mucronate point...

We consider the NP-hard Tree Containment problem that has important applications in phylogenetics. The problem asks if a given leaflabeled network contains a subdivision of a given leaf-labeled tree. We develop a fast algorithm for the case that the input network is indeed a tree in which multiple leaves might share a label. By combining this algorithm with a generalization of a previously know...

Knowledge and information transfer have become important ingredients for an organisation's competitive advantage. Knowledge management has emerged as an overarching strategy to enhance knowledge creation, information transfer, utilisation, and reticulation in order to generate innovation and improve organisational performance. Part of this strategy involves the creation of Communities of Practi...

Given a finite setX, a collection T of rooted phylogenetic trees onX and an integer k, the Hybridization Number problem asks if there exists a phylogenetic network on X that displays all trees from T and has reticulation number at most k. We show two kernelization algorithms for Hybridization Number, with kernel sizes 4k(5k) and 20k(∆ − 1) respectively, with t the number of input trees and ∆ th...

The search space of rooted phylogenetic trees is vast and a major research focus of recent decades has been the development of algorithms to effectively navigate this space. However this space is tiny when compared with the space of rooted phylogenetic networks, and navigating this enlarged space remains a poorly understood problem. This, and the difficulty of biologically interpreting such net...

A new soft scale (Hemiptera: Coccoidea: Coccidae) species, Pulvinariacaballeroramosae Tanaka & Kondo, sp. n., is described from specimens collected on twigs of Ficussoatensis Dugand (Moraceae) in Bogota, Colombia. The new species resembles Pulvinariadrymiswinteri Kondo & Gullan, described from Chile on Drimyswinteri J.R. Forst. & G. Forst. (Winteraceae), but differs in the distribution of preop...

This chapter is dedicated to the simulation of composite forming processes. It concerns numerical methods for molding, at the different material scales, involving multiphysics analysis. From the different possible numerical techniques, we focus on a stabilized finite element method for the resolution of the continuum equations (mass, momentum and energy conservation), in an Eulerian framework, ...
