A pilot variational coupled reanalysis based on the CESAM climate model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Operational all‐sky assimilation of geostationary infrared water‐vapour channels in the regional ICON‐D2 model with an ensemble Kalman filter

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Though many studies have shown potential benefit in assimilating all‐sky infrared radiances from geostationary satellites, at numerical weather prediction centres it is still common practice to assimilate clear‐sky radiances. We present the operationalization of the all‐sky assimilation of the spinning enhanced visible and infrared imager (SEVIRI ...

Le criminel tel qu’il est représenté et étudié dans la revue Criminologie entre 1968 et 2016

open access: yesCriminologie, 2018
Cet article examine la couverture et le traitement du criminel dans la revue Criminologie. Pour observer la représentation du criminel et son étude à travers le temps, des articles empiriques publiés entre 1968 et 2016 qui répondent à certains critères ...

Simulating Quantum State Transfer Between Distributed Devices Using Noisy Interconnects

open access: yesAdvanced Quantum Technologies, EarlyView.
Noisy connections challenge future networked quantum computers. This work presents a practical method to address this by simulating an ideal state transfer over noisy interconnects. The approach reduces the high sampling cost of previous methods, an advantage that improves as interconnect quality gets better.

Efficient Data Assimilation Method for Optimizing Prediction of Flow Field and Sediment Transport in Open Channel

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter ks in a shallow‐water equation model (via the momentum ...

Le contrôle plurinormatif des gangs de rue : contributions des études sur la délinquance des élites à la compréhension de la judiciarisation de la criminalité de rue

open access: yesCriminologie, 2016
Edwin Sutherland a été l’un des premiers à remettre en question l’association entre pauvreté et criminalité qui dominait le champ criminologique au début du xxe siècle.

Characterizations of Ordered Self-adjoint Operator Spaces

open access: yes, 2016
In this paper, we generalize the work of Werner and others to develop two abstract characterizations for self-adjoint operator spaces. The corresponding abstract objects can be represented as self-adjoint subspaces of $B(H)$ in such a way that both a ...

Errors in reconstruction of dichroic X‐ray orientation tomography due to polarization rotation of the incident beam

open access: yesJournal of Synchrotron Radiation, EarlyView.
Linear dichroic X‐ray tomography is a technique in which the linear dichroism of anisotropic materials is used to image crystal orientation in three dimensions. We show that the reconstruction of tomograms is subject to errors due to the change in polarization on propagation through the material and propose strategies for mitigating these effects ...

Numéro spécial : Quelles innovations pour quels systèmes d'élevage ?

open access: yesINRAE Productions Animales, 2014
Anant-propos « Innover » est un mot d’ordre sociétal qui encourage la communauté des chercheurs à produire des connaissances, des démarches et des outils visant à faire « autrement », à changer de paradigme, ou tout au moins de modèle de production ...
