Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed

Proposition méthodologique pour la visualisation et l'exploration des mobilités géographiques
2016
Daily mobility data are multidimensional and desaggregated, what make them hard to manipulate and to analyze. Although methods of representation and analyze have been proposed, none of them seem to be able to efficiently bring out knowledge from data. We propose to combinate this solutions and a methodology of innovative reaggregation to visualize and explore mobility data.

“Voz del alumnado”: hacer de los estudiantes participantes activos y responsables en los procesos formativos activados en la escuela y en la universi…
2017
"Voce degli studenti" è un movimento pedagogico nato negli anni novanta in alcuni paesi di lingua inglese (Stati Uniti, Canada, Inghilterra e Australia). Supporta la partecipazione attiva e responsabile degli studenti ai processi di formazione attivati nella scuola e nell'università. Per includere le voci degli studenti in questi processi, gli adulti (insegnanti e amministratori) devono riconoscere i loro diritti di essere ascoltati e rispettati come persone con interessi, bisogni di apprendimento e idee che possono risolvere i problemi della didattica scolastica/universitaria, della ricerca educativa e delle politiche culturali in cui si devono prendere decisioni che li riguardano. In ques…
First volatile inventory for Gorely volcano, Kamchatka
2012
We report here the very first assessment of volatile flux emissions from Gorely, an actively degassing volcano in Kamchatka. Using a variety of in situ and remote sensing techniques, we determined the bulk plume concentrations of major volatiles (H2O 93.5%, CO2, 2.6%, SO2 2.2%, HCl 1.1%, HF 0.3%, H2 0.2%) and trace-halogens (Br, I), therefore estimating a total gas release of 11,000 tons·day−1 during September 2011, at which time the target was non-eruptively degassing at 900°C. Gorely is a typical arc emitter, contributing 0.3% and 1.6% of the total global fluxes from arc volcanism for CO2 and HCl, respectively. We show that Gorely's volcanic gas (H2O/SO2 43, CO2/SO2 1.2, HCl/SO2 0.5) is a…
Chemistry and fluxes of major and trace element from worldwide passive degassing volcanoes: a critical review
2015
Volcanic emissions represent one of the most important natural sources of trace elements (e.g. As, Cd, Cu, Hg, Pb, Sb, Tl and Zn) into the atmosphere, sequentially influencing the hydrosphere, lithosphere and biosphere. The human health hazard during episodic volcanic eruptions generally follows from deposition of coarse and fine particles (2.5-10 and < 2.5 μm) that produces effects such as asthma and lung and respiratory disease. Regarding passive degassing volcanoes, the harmful effects of fluorine fumigation are known both for vegetation (foliar necrosis) and human/animals (fluorosis), but only a few studies have been focused on the effects of potentially toxic trace elements. From a …
A model of degassing for Stromboli volcano
2010
International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…
Sulfur Degassing From Steam-Heated Crater Lakes: El Chichón (Chiapas, Mexico) and Víti (Iceland)
2018
The composition of the gases released by El Chichón (Chiapas, Mexico) and Víti (Askja volcano, Iceland) volcanic lakes is examined by Multi-GAS for the first time. Our results demonstrate that H2S and SO2 are degassed by these pH 2–3 lakes. We find higher CO2/H2S and H2/H2S ratios in the lakes' emissions (31–5,685 and 0.6–35, respectively) than in the fumarolic gases feeding the lakes (13–33 and 0.08–0.5, respectively), evidencing that only a fraction (0.2–5.4% at El Chichón) of the H2S(g) contributed by the subaquatic fumaroles ultimately reaches the atmosphere. At El Chichón, we estimate a H2S output from the crater lake of 0.02–0.06 t/day. Curiously, SO2 is also detected at trace levels …
