Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical composition between the Sun and the Earth and othe
We show how a multi-resolution network can model the development of acuity and coarse-to-fine processing in the mammalian visual cortex. The network adapts to input statistics in an unsupervised manner, and learns a coarse-to-fine representation by using cumulative inhibition of nodes within a network layer. We show that a system of such layers can represent input by hierarchically composing large
In this article I examine the current European refugee ‘crisis’ by challenging, from a theoretical perspective, the way in which the European Union (EU) has used the increased number of deaths in the Mediterranean as an opportunity to frame recent migration flows as an emergency which, by definition, can only be addressed through the adoption of exceptional measures. Throughout the article, I enga
This article examines the involvement of Private Military and Security Companies (PMSC) in both shaping and implementing the European Agenda on Migration (European Agenda), launched by the European Union in May 2015. The migration policies which have since been adopted have increasingly enabled the outsourcing to private security contractors of various border control operations, including those re
This book analyses the way in which international human rights law (IHRL) and international investment law (IIL) are deployed – or fail to be deployed – in conflict countries within the context of natural resources extraction. It specifically analyses the way in which IIL protections impact on the parallel protection of economic, social and cultural rights (ESC rights) in the host state, especiall
During the first five months of 2015 approximately 1,850 people died across the Mediterranean whilst attempting to reach the European Union (EU). In response to this, in April 2015 the Commission presented a 10-point action plan, on the basis of which the Council agreed to strengthen the EU’s ‘presence at sea, to fight traffickers, to prevent illegal migration flows and to reinforce internal solid
