Understanding and quantifying the seasonal and spatial distribution of planktic foraminiferal fluxes reflected in sedimentary assemblages is key to interpret foraminiferabased proxies in paleoceanography. Towards this goal we present an empirical model to predict foraminiferal fluxes on a global scale. A compilation of planktic foraminiferal flux and export production data from globally distrib...

European), a failure (L’Echo), a betrayer of ambitions (De Standaard), a result that nobody wanted (Libération), a wound leaving Europe disabled (Le Soir). In such a mood one would be eager hastily to throw away in the stream the failing EU and its unfinished Treaty. However, this would amount to throwing the baby out with the bathwater. Wisdom does not advise anybody to do so but rather to com...

In many lock-free algorithms, threads help one another, and each operation creates a descriptor that describes how other threads should help it. Allocating and reclaiming descriptors introduces significant space and time overhead. We introduce the first descriptor abstract data type (ADT), which captures the usage of descriptors by lock-free algorithms. We then develop a weak descriptor ADT whi...

In this paper we will explain how to perfectly hedge under Heston’s stochastic volatility model with jump to default, which is in itself a generalization of the Merton jump-to-default model and a special case of the Heston model with jumps. The hedging instruments we use to build the hedge will be as usual the stock and the bond, but also the Variance Swap (VS) and a Credit Default Swap (CDS). ...
