The trade of non-native pets, especially of non-domesticated and exotic animals, and their subsequent release and establishment of populations is one of the major pathways Blender of introduction for invasive alien reptiles, amphibia, birds and mammals.Here, we use a group of arboreal mammals, tree squirrels of the genus Callosciurus, as a well-doc
Modern vehicles as well as structures consist more and more often of a multi material mix.In addition to the use of light materials (e.g.aluminium) to optimise lightweight construction potential, higher strength alloys are being used more and more frequently.With the different material combinations, the requirements for the joining technology also
We present a micromagnetic study of a ferromagnetically exchange-coupled composite free layer design for perpendicular magnetic tunnel junctions.The thermal stability factor and critical switching current density depend on the exchange coupling strength and Blender effective anisotropy ratio between the sublayers of the composite free layer.The ene
Methods of balance control for a legged robot, the model of which is presented as a two-section inverted pendulum, are considered.The following balance methods for humanoid robots are analysed: the parallel Jacket algorithm of the network operator method; the method of natural synergies; the method of Pants fuzzy control, the spherical inverted pen
BACKGROUND:Hepatitis B virus (HBV) infection is an increasingly important cause of morbidity and mortality in HIV-infected adults.This study aimed to determine the prevalence and incidence of HBV in the UK CHIC Study, a multicentre observational cohort.METHODS AND FINDINGS:12 HIV treatment centres were included.Of 37,331 patients, 27,450 had at lea
