Linear-time CUR approximation of BEM matrices
In this paper we propose linear-time CUR approximation algorithms for admissible matrices obtained from the hierarchical form of Boundary Element matrices. We propose a new approach called geometric sampling to obtain indices of most significant rows and columns usinginformation from the domains where the problem is posed. Our strategy is tailored ...

Is the Risk of Myocardial Infarction in People With Human Immunodeficiency Virus (HIV) Associated With Atazanavir or Dar...
...
Background: The Data Collection on Adverse Events of Anti-HIV Drugs (DAD) study has reported an increased risk of cardiovascular diseases in people with human immunodeficiency virus who were exposed to darunavir (DRV) but not to atazanavir (ATV). Our objective was to evaluate associations between ATV or DRV exposures and the risk of myocardial infa...
Molecular streaming and its voltage control in ångström-scale channels
Published in Nature
Pressure-driven transport of aqueous salts through ångström-scale channels created from two-dimensional materials shows a transistor-like effect in which applying a tiny bias voltage can increase transport by up to 20 times.
Lyapunov characterization of uniform exponential stability for nonlinear infinite-dimensional systems
In this paper we deal with infinite-dimensional nonlinear forward complete dynamical systems which are subject to external disturbances. We first extend the well-known Datko lemma to the framework of the considered class of systems. Thanks to this generalization, we provide characterizations of the uniform (with respect to disturbances) local, semi...
Covariance and Controvariance: a fresh look at an old issue: a primer in advanced type systems for learning functional p...
Twenty years ago, in an article titled "Covariance and contravariance: conflict without a cause", I argued that covariant and contravariant specialization of method parameters in object-oriented programming had different purposes and deduced that, not only they could, but actually they should both coexist in the same language. In this work I reexam...
On Randomisation In Computational Inverse Problems
In this paper we discuss the use of randomisation in inverse problems. We review several examples, and we distinguish between cases where random measurements are used, as in compressed sensing or in passive imaging with ambient noise, and cases where the unknowns themselves are randomised, as in inverse problems using deep learning or the randomise...
Prospects for Fundamental Physics with LISA
...
We provide an updated assessment of the fundamental physics potential of LISA. Given the very broad range of topics that might be relevant to LISA, we present here a sample of what we view as particularly promising directions, based in part on the current research interests of the LISA scientific community in the area of fundamental physics. We org...
QUBIC: the Q & U Bolometric Interferometer for Cosmology
...
The Q & U Bolometric Interferometer for Cosmology, QUBIC, is an innovative experiment designed to measure the polarization of the Cosmic Microwave Background and in particular the signature left therein by the inflationary expansion of the Universe. The expected signal is extremely faint, thus extreme sensitivity and systematic control are necessar...
