Emitting CO2 today means creating a flow of climate damage over several decades. What is the value of this flow? How can 50 years of developments in the theory of finance shed light on the problem of "carbon value"? Documents and media Download …

Abstract The theory of gamma-ray bursts, whether a hypernova explosion or a neutron star merger, involves a fireball that propagates in very rapid time, emitting high-energy gamma rays. Shock waves and cosmic ray acceleration accompany this fireball. …

Résumé Les solides poreux hybrides de type Metal Organic Frameworks (MOF) sont des composés cristallins micro- ou méso-poreux possédant une diversité chimique et structurale exceptionnelle, conduisant à des propriétés d’adsorption (sélectivité, …

Abstract Gamma-ray bursts are fireballs resulting from the merger of two neutron stars, or a black hole and a neutron star. High-energy particles are emitted along with intense radiation. Documents and media Download …

Abstract The energy density of Li-metal batteries is governed by the composition of the materials, which affects their crystallographic and electronic structure, and hence their redox potential. Replacing sulfur with oxygen produces high-potential …

Circulation of concepts in the media and social networks Social networks as a battlefield : attention dynamics and concept circulation in the Twittersphere From politics to discussions on global warming to debates on vaccination, social networks are …

The discovery of the Sumerians of the 3rd millennium began with the excavation of Tello in 1877, but since then the question of the nature of their civilization has never ceased to be raised. We'll see how scholars of the early 2nd millennium B.C. largely …

Abstract Photovoltaics has great potential, not only because of the resource it uses, but also because the performance of current systems, despite the impressive progress made in recent decades, is still a long way from that predicted by theory. A first …

With photovoltaics, mankind gained access for the first time to a means of producing electrical energy that did not involve rotating parts and the steam thermal cycle. This was made possible by the discovery of the semi-conducting properties of certain …

Abstract The various theories outlined last week each have limitations that prevent them from claiming exclusivity, so we can't avoid a certain eclecticism, i.e. the simultaneous use of several of the rival theories. With this in mind, we need to begin by …

Abstract Continuing the investigation into archaic eunomia , this lesson looks first at the scope of the term nomos in the work of Hesiod. On the divine level, in the Theogony , the goddess Eunomia is the daughter of Themis and Zeus. As for the nomoi that …

Abstract I'll start by presenting an overview of how to test models and estimate their parameters. I will then show how these concepts are used to analyze data at different levels of complexity. Finally, I will present applications in astrophysics and …

Abstract Under regularity assumptions, the maximum likelihood estimator is shown to be consistent. Fisher information is defined as the variance of the score, which is the gradient of the log likelihood. It is also shown to be the Hessian of the negative …
