Integrating Structure and Attributes for Transportation Network Partitioning via Optimal Transport
Ketsia Guichard-Sustowski, Loïc Le Marrec, Véronique Thelen
Transportation network partitioning is essential for applications such as traffic analysis, simulation, and mobility pattern identification. However, transportation networks combin…
Modeling phononic band gap in microstructured solids using the Riemann-Cartan geometric framework
Ilya Peshkov, Loïc Le Marrec
This paper discusses the modeling of acoustic wave fields in microstructured elastic solids within the framework of Riemann-Cartan geometry. We consider a scenario in which microst…
Optimal Transport-Based Clustering of Attributed Graphs with an Application to Road Traffic Data
Ioana Gavra, Ketsia Guichard-Sustowski, Loïc Le Marrec
In many real-world contexts, such as social or transport networks, data exhibit both structural connectivity and node-level attributes. For example, roads in a transport network ca…
A New Framework for Unidimensional Structures Based on Generalised Continua
Mewen Crespo, Casale Guy, Loïc Le Marrec +1
The present work introduces a family of beam models derived from a three-dimensional higher-order elasticity framework. By incorporating three kinematic fields - the macroscopic di…
Defects in unidimensional structures
Mewen Crespo, Guy Casale, Loïc Le Marrec +1
In a previous work of the first authors, a non-holonomic model, generalising the micromorphic models and allowing for curvature (disclinations) to arise from the kinematic values,…
Timoshenko beam under finite and dynamic transformations: Lagrangian coordinates and Hamiltonian structures
Oscar Cosserat, Loïc Le Marrec
In the framework of Timoshenko beam, the material parameters are inherently prescribed on the material moving frame. In this regard, we derive the strong and weak formulations of t…
Toward a universal model for spatially structured populations
Loïc Marrec, Irene Lamberti, Anne-Florence Bitbol
A key question in evolution is how likely a mutant is to take over. This depends on natural selection and on stochastic fluctuations. Population spatial structure can impact mutant…
Adapt or perish: Evolutionary rescue in a gradually deteriorating environment
Loïc Marrec, Anne-Florence Bitbol
We investigate the evolutionary rescue of a microbial population in a gradually deteriorating environment, through a combination of analytical calculations and stochastic simulatio…
Resist or perish: fate of a microbial population subjected to a periodic presence of antimicrobial
Loïc Marrec, Anne-Florence Bitbol
The evolution of antimicrobial resistance can be strongly affected by variations of antimicrobial concentration. Here, we study the impact of periodic alternations of absence and p…
Symmetry in cancer networks identified: Proposal for multi-cancer biomarkers
Pramod Shinde, Loic Marrec, Aparna Rai +5
One of the most challenging problems in biomedicine and genomics is the identification of disease biomarkers. In this study, proteomics data from seven major cancers were used to c…
Antibody-mediated cross-linking of gut bacteria hinders the spread of antibiotic resistance
Florence Bansept, Loïc Marrec, Anne-Florence Bitbol +1
The body is home to a diverse microbiota, mainly in the gut. Resistant bacteria are selected for by antibiotic treatments, and once resistance becomes widespread in a population of…
Quantifying the impact of a periodic presence of antimicrobial on resistance evolution in a homogeneous microbial population of fixed size
Loïc Marrec, Anne-Florence Bitbol
The evolution of antimicrobial resistance generally occurs in an environment where antimicrobial concentration is variable, which has dramatic consequences on the microorganisms' f…
Analysing degeneracies in networks spectra
Loïc Marrec, Sarika Jalan
Many real-world networks exhibit a high degeneracy at few eigenvalues. We show that a simple transformation of the network's adjacency matrix provides an understanding of the origi…
