Ce que les machines ont vu et que nous ne savons pas encore
Frédéric Kaplan, Isabella Di Lenardo
Cet article conceptualise l’idée qu’il existe une « matière noire » composée des structurations latentes identifiées par le regard machinique sur de grandes collections photographiques patrimoniales. Les campagnes photographiques de l’histoire de l’art, au ...
2023Typicality results for weak solutions of the incompressible Navier-Stokes equations
Maria Colombo, Luigi De Rosa, Massimo Sorella
In this work we show that, in the class of L-infinity((0,T); L-2(T-3)) distributional solutions of the incompressible Navier-Stokes system, the ones which are smooth in some open interval of times are meagre in the sense of Baire category, and the Leray on ...
EDP SCIENCES S A2022Bootstrapping for Approximate Homomorphic Encryption with Negligible Failure-Probability by Using Sparse-Secret Encapsulation
Jean-Pierre Hubaux, Juan Ramón Troncoso-Pastoriza, Jean-Philippe Léonard Bossuat
Bootstrapping parameters for the approximate homomorphic-encryption scheme of Cheon et al., CKKS (Asiacrypt 17), are usually instantiated using sparse secrets to be efficient. However, using sparse secrets constrains the range of practical parameters withi ...
SPRINGER INTERNATIONAL PUBLISHING AG2022Shrinking Bouma's window: How to model crowding in dense displays
Michael Herzog, Gregory Francis, Adrien Christophe Doerig, Alban Bornet
In crowding, perception of a target deteriorates in the presence of nearby flankers. Traditionally, it is thought that visual crowding obeys Bouma's law, i.e., all elements within a certain distance interfere with the target, and that adding more elements ...
PUBLIC LIBRARY SCIENCE2021Mechanical properties and cytocompatibility of dense and porous Zn produced by laser powder bed fusion for biodegradable implant applications
Andreas Mortensen, Ludger Weber, Karel Lietaert
In this work, the macrotexture of dense Zn produced by laser powder bed fusion (LPBF) was studied and the mechanical properties for different tensile bar orientations were measured. The compressive strength of LPBF Zn scaffolds with five different unit cel ...
ELSEVIER SCI LTD2020Shrinking Bouma's window: Visual crowding in dense displays
Michael Herzog, Gregory Francis, Adrien Christophe Doerig, Alban Bornet
In crowding, perception of a target deteriorates in the presence of nearby flankers. In the traditional feedforward framework of vision, only elements within Bouma’s window interfere with the target and adding more elements always leads to stronger crowdin ...
SAGE PUBLICATIONS LTD2019The modern analogue of a Cretaceous coral with a calcitic skeleton
Anders Meibom, Jaroslaw Hubert Stolarski
It was argued that, in contrast to all known modern scleractinian corals that form aragonite skeletons, the original mineralogy of the Cretaceous "Coelosmilia" (ca. 70-65 Ma) was calcite during a period when the Mg2+/Ca2+ ratio of the seawater was presumab ...
2019Two- to three-dimensional crossover in a dense electron liquid in silicon
Doping of silicon via phosphine exposures alternating with molecular beam epitaxy overgrowth is a path to Si:P substrates for conventional microelectronics and quantum information technologies. The technique also provides a well-controlledmaterial for syst ...
AMER PHYSICAL SOC2018Influence of heterogeneities on crack propagation
Jean-François Molinari, Okan Yilmaz, Jérémy Bleyer
The influence of material heterogeneities is studied in the context of dynamic failure. We consider a pre-strained plate problem, the homogeneous case of which has been widely studied both experimentally and numerically. This setup is used to isolate the e ...
2018Convex block-sparse linear regression with expanders - provably
Volkan Cevher, Quoc Tran Dinh, Anastasios Kyrillidis, Luca Baldassarre, Bubacarr Bah
Sparse matrices are favorable objects in machine learning and optimization. When such matrices are used, in place of dense ones, the overall complexity requirements in optimization can be significantly reduced in practice, both in terms of space and run-ti ...
