We performed a chemical analysis of the asteroid-bearing white dwarf WD 1145+017 using optical and ultraviolet spectroscopic data from 25 epochs between 2015 and 2023. We present an updated gas disk model with improved opacity calculations and temper

Whether deterministic or stochastic, models can be viewed as functions designed to approximate a specific quantity of interest. We propose a data-driven framework that aggregates predictions from diverse models into a single, more accurate output. Th

In this paper we study the exponential twist, i.e. a path-integral exponential change of measure, of a Markovian reference probability measure $\P$. This type of transformation naturally appears in variational representation formulae originating from

In this paper, we propose an original approach to stochastic control problems. We consider a weak formulation that is written as an optimization (minimization) problem on the space of probability measures. We then introduce a penalized version of thi

Les émotions jouent un rôle non négligeable dans le processus d’apprentissage [1]. Le présent article a pour but d'explorer dans quelle mesure les usages des traducteurs en ligne par les lycéens sont liés aux enjeux affectifs relatifs à l’

In distributed predictive control structures, communication among agents is required to achieve a consensus and approach an optimal global behavior. Such negotiation mechanisms are sensitive to attacks on these exchanges. This paper proposes a monito

Controlling large-scale systems sometimes requires decentralized computation. Communication among agents is crucial to achieving consensus and optimal global behavior. These negotiation mechanisms are sensitive to attacks on those exchanges. This pap

The present paper describes a proof of concept showing the ability of ultrasound time of flight measurements to complement existing temperature measurements in a laser powder bed fusion additive manufacturing process. To this end, two printers (a 3D

Human pluripotent stem cells (hiPSC) represent a unique opportunity to model lung development and chronic bronchial diseases. We generated a hiPSC line from a highly characterized healthy heavy smoker male donor free from emphysema or tobacco related
