Leaf growth is conformal
Karen Alim, Shahaf Armon, Boris I. Shraiman +1
Growth pattern dynamics lie at the heart of morphogenesis. Here, we investigate the growth of plant leaves. We compute the conformal transformation that maps the contour of a leaf…
Geophysical flows under location uncertainty, Part III: SQG and frontal dynamics under strong turbulence conditions
Valentin Resseguier, Etienne Memin, Bertrand Chapron
Models under location uncertainty are derived assuming that a component of the velocity is uncorrelated in time. The material derivative is accordingly modified to include an advec…
Geophysical flows under location uncertainty, Part II: Quasi-geostrophy and efficient ensemble spreading
Valentin Resseguier, Etienne Memin, Bertrand Chapron
Models under location uncertainty are derived assuming that a component of the velocity is uncorrelated in time. The material derivative is accordingly modified to include an advec…
Stochastic modelling and diffusion modes for proper orthogonal decomposition models and small-scale flow analysis
Valentin Resseguier, Etienne Mémin, Dominique Heitz +1
We present here a new stochastic modelling in the constitution of fluid flow reduced-order models. This framework introduces a spatially inhomogeneous random field to represent the…
Geophysical flows under location uncertainty, Part I Random transport and general models
Valentin Resseguier, Etienne Mémin, Bertrand Chapron
A stochastic flow representation is considered with the Eulerian velocity decomposed between a smooth large scale component and a rough small-scale turbulent component. The latter…
Aboveground biomass mapping in French Guiana by combining remote sensing, forest inventories and environmental data
Ibrahim Fayad, Nicolas Baghdadi, Stéphane Guitet +5
Mapping forest aboveground biomass (AGB) has become an important task, particularly for the reporting of carbon stocks and changes. AGB can be mapped using synthetic aperture radar…
A generic framework for the development of geospatial processing pipelines on clusters
Remi Cresson
The amount of remote sensing data available to applications is constantly growing due to the rise of very-high-resolution sensors and short repeat cycle satellites. Consequently, t…
Learning through experimenting: an original way of teaching geometrical optics
C. Even, C. Balland, V. Guillet
Over the past 10 years, we have developed at University Paris Sud a first year course on geometrical optics centered on experimentation. In contrast with the traditional top-down l…
Gaussian approximations for chemostat models in finite and infinite dimensions
Bertrand Cloez, Coralie Fritsch
In a chemostat, bacteria live in a growth container of constant volume in which liquid is injected continuously. Recently, Campillo and Fritsch introduced a mass-structured individ…
Limiting Hamilton-Jacobi Equation for the Large Scale Asymptotics of a Subdiffusion Jump-Renewal Equation
Vincent Calvez, Pierre Gabriel, Álvaro Mateos González
Subdiffusive motion takes place at a much slower timescale than diffusive motion. As a preliminary step to studying reaction-subdiffusion pulled fronts, we consider here the hyperb…
Mathematical model for pest-insect control using mating disruption and trapping
Roumen Anguelov, Claire Dufourd, Yves Dumont
Controlling pest insects is a challenge of main importance to preserve crop production. In the context of Integrated Pest Management (IPM) programs, we develop a generic model to s…
Using a terrestrial laser scanner to characterize vegetation-induced flow resistance in a controlled channel
Fabrice Vinatier, Jean-Stéphane Bailly, Gilles Belaud +1
Vegetation characteristics providing spatial heterogeneity at the channel reach scale can produce complex flow patterns and the relationship between plant patterns morphology and f…
Solution landscapes in nematic microfluidics
Maria Crespo, Ian Griffiths, Apala Majumdar +1
We study the static equilibria of a simplified Leslie--Ericksen model for a unidirectional uniaxial nematic flow in a prototype microfluidic channel, as a function of the pressure…
Constrained Allocation Flux Balance Analysis
Matteo Mori, Terence Hwa, Olivier C. Martin +2
New experimental results on bacterial growth inspire a novel top-down approach to study cell metabolism, combining mass balance and proteomic constraints to extend and complement F…
On a Possible Similarity between Gene and Semantic Networks
Nicolas Turenne
In several domains such as linguistics, molecular biology or social sciences, holistic effects are hardly well-defined by modeling with single units, but more and more studies tend…
Bayesian optimization under mixed constraints with a slack-variable augmented Lagrangian
Victor Picheny, Robert B. Gramacy, Stefan M. Wild +1
An augmented Lagrangian (AL) can convert a constrained optimization problem into a sequence of simpler (e.g., unconstrained) problems, which are then usually solved with local solv…
Using numerical plant models and phenotypic correlation space to design achievable ideotypes
Victor Picheny, Pierre Casadebaig, Ronan Trépos +4
Numerical plant models can predict the outcome of plant traits modifications resulting from genetic variations, on plant performance, by simulating physiological processes and thei…
Optimal enzyme rhythms in cells
Wolfram Liebermeister
Cells can use periodic enzyme activities to adapt to periodic environments or existing internal rhythms and to establish metabolic cycles that schedule biochemical processes in tim…
Ergodicity of inhomogeneous Markov chains through asymptotic pseudotrajectories
Michel Benaïm, Florian Bouguet, Bertrand Cloez
In this work, we consider an inhomogeneous (discrete time) Markov chain and are interested in its long time behavior. We provide sufficient conditions to ensure that some of its as…
