Detection of Common Subtrees with Identical Label Distribution
Romain Azaïs, Florian Ingels
Frequent pattern mining is a relevant method to analyse structured data, like sequences, trees or graphs. It consists in identifying characteristic substructures of a dataset. This…
Emergence of tip singularities in dissolution patterns
Martin Chaigne, Sabrina Carpy, Marion Massé +3
Chemical erosion, one of the two major erosion processes along with mechanical erosion, occurs when a soluble rock like salt, gypsum or limestone is dissolved in contact with a wat…
Is incoherence required for sustainability?
Olivier Hamant
Unstoppable feedback loops and tipping points in socio-ecological systems are the main threats to sustainability. These behaviors have been extensively studied, notably to predict,…
Multiscale modelling and analysis of growth of plant tissues
Arezki Boudaoud, Annamaria Kiss, Mariya Ptashnyk
How morphogenesis depends on cell properties is an active direction of research. Here, we focus on mechanical models of growing plant tissues, where microscopic (sub)cellular struc…
Absent daddy, but important father
Nathanaël Jacquier, Thomas Widiez
Mixing maternal and paternal genomes is the base of plant sexual reproduction, but some so-called 'haploid inducer lines' lead to the formation of seeds bearing well-developed embr…
Isomorphic unordered labeled trees up to substitution ciphering
Florian Ingels, Romain Azaïs
Given two messages - as linear sequences of letters, it is immediate to determine whether one can be transformed into the other by simple substitution cipher of the letters. On the…
Cellular Fourier analysis for geometrically disordered materials
Antoine Fruleux, Arezki Boudaoud
Many media are divided into elementary units with irregular shape and size, as exemplified by domains in magnetic materials, bubbles in foams, or cells in biological tissues. Such…
Enumeration of Irredundant Forests
Florian Ingels, Romain Azaïs
Reverse search is a convenient method for enumerating structured objects, that can be used both to address theoretical issues and to solve data mining problems. This method has alr…
Bounds on mixed state entanglement
Bruno Leggio, Anna Napoli, Hiromichi Nakazato +1
In the general framework of mixed states, we derive an explicit bound for bipartite NPT entanglement based on the mixedness characterization of the physical system. The…
Patterns of polar domains in a spatiotemporal model of interacting polarities
Maryam Aliee, Arezki Boudaoud
Polarity fields are known to exhibit long distance patterns, in both physical and biological systems. The mechanisms behind such patterns are poorly understood. Here, we describe t…
The Weight Function in the Subtree Kernel is Decisive
Romain Azaïs, Florian Ingels
Tree data are ubiquitous because they model a large variety of situations, e.g., the architecture of plants, the secondary structure of RNA, or the hierarchy of XML files. Neverthe…
Approximation of trees by self-nested trees
Romain Azaïs, Jean-Baptiste Durand, Christophe Godin
The class of self-nested trees presents remarkable compression properties because of the systematic repetition of subtrees in their structure. In this paper, we provide a better co…
A mechanism of macroscopic rigid-body behavior through evanescent mode
K. Sekimoto, Y. M. Benane, K. E. Alloubia +2
It has been numerically found that the setup of Newton's cradle can exhibit a rigid-body like behavior, that is, the target cluster starts to move collectively without emitting the…
Elongation and shape changes in organisms with cell walls: a dialogue between experiments and models
Jean-Daniel Julien, Arezki Boudaoud
The generation of anisotropic shapes occurs during morphogenesis of almost all organisms. With the recent renewal of the interest in mechanical aspects of morphogenesis, it has bec…
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…
Stuttering Min oscillations within E. coli bacteria: A stochastic polymerization model
Supratim Sengupta, Julien Derr, Anirban Sain +1
We have developed a 3D off-lattice stochastic polymerization model to study subcellular oscillation of Min proteins in the bacteria Escherichia coli, and used it to investigate the…
A comparative study of crumpling and folding of thin sheets
Stephanie Deboeuf, Eytan Katzav, Arezki Boudaoud +2
Crumpling and folding of paper are at rst sight very di erent ways of con ning thin sheets in a small volume: the former one is random and stochastic whereas the latest one is regu…
Measuring order in the isotropic packing of elastic rods
E. Bayart, S. Deboeuf, F. Corson +2
The packing of elastic bodies has emerged as a paradigm for the study of macroscopic disordered systems. However, progress is hampered by the lack of controlled experiments. Here w…
Statistical distributions in the folding of elastic structures
Mokhtar Adda-Bedia, Arezki Boudaoud, Laurent Boué +1
The behaviour of elastic structures undergoing large deformations is the result of the competition between confining conditions, self-avoidance and elasticity. This combination of…
