The HANDY model with non-renewable resources and societal effects
Mathilde Badoual, Basil Grammaticos, Stéphane Plaszczynski +1
We present an extension of the single-population Human and Nature Dynamics (HANDY) model that explicitly incorporates non-renewable resources and societal effects. The model is for…
A stochastic model of discussion
S. Plaszczynski, B. Grammaticos, M. Badoual
We consider the duration of discussions in face-to-face contacts and propose a stochastic model to describe it. It is based on the points of a Levy flight where the duration of eac…
On the duration of face-to-face contacts
Stephane Plaszczynski, Gilberto Nakamura, Basile Grammaticos +1
The analysis of social networks, in particular those describing face-to-face interactions between individuals, is complex due to the intertwining of the topological and temporal as…
Predicting regrowth of low-grade gliomas after radiotherapy
Stephane Plaszczynski, Basile Grammaticos, Johan Pallud +2
Diffuse low grade gliomas are invasive and incurable brain tumours that inevitably transform into higher grade ones. A classical treatment to delay this transition is radiotherapy…
Levy geometric graphs
S. Plaszczynski, G. Nakamura, C. Deroulers +2
We present a new family of graphs with remarkable properties. They are obtained by connecting the points of a random walk when their distance is smaller than a given scale. Their d…
Modeling cooperation and competition in biological communities
F. Meloni, G. Nakamura, B. Grammaticos +2
The far-reaching consequences of ecological interactions in the dynamics of biological communities remain an intriguing subject. For decades, competition has been a cornerstone in…
Radiotherapy Effects on Diffuse Low-Grade Gliomas: Confronting Theory With Clinical Data
Leo Adenis, Stephane Plaszczynski, Basile Grammaticos +2
Diffuse low grade gliomas are slowly growing tumors that always recur after treatment. In this paper, we revisit the modeling of the tumor radius evolution before and after the rad…
Dispersal and organization of polarized cells: non-linear diffusion and cluster formation without adhesion
G. Nakamura, M. Badoual, E. Fabiani +1
Experimental studies of cell motility in culture have shown that under adequate conditions these living organisms possess the ability to organize themselves into complex structures…
Confinement strategies in a simple SIR model
G. Nakamura, B. Grammaticos, M. Badoual
We propose a simple SIR model in order to investigate the impact of various confinement strategies on a most virulent epidemic. Our approach is motivated by the current COVID-19 pa…
Quantitative characterization of the imaging limits of diffuse low-grade oligodendrogliomas
Chloé Gerin, Johan Pallud, Christophe Deroulers +7
Background : Supratentorial diffuse low-grade gliomas in adults extend beyond maximal visible MRI-defined abnormalities, and a gap exists between the imaging signal changes and the…
Automatic quantification of the microvascular density on whole slide images, applied to paediatric brain tumours
Christophe Deroulers, Volodia Dangouloff-Ros, Mathilde Badoual +2
Angiogenesis is a key phenomenon for tumour progression, diagnosis and treatment in brain tumours and more generally in oncology. Presently, its precise, direct quantitative assess…
Analyzing huge pathology images with open source software
Christophe Deroulers, David Ameisen, Mathilde Badoual +3
Backgr: Digital pathology images are increasingly used both for diagnosis and research, because slide scanners are nowadays broadly available and because the quantitative study of…
Exclusion processes: short range correlations induced by adhesion and contact interactions
Gianluca Ascolani, Mathilde Badoual, Christophe Deroulers
We analyze the out-of-equilibrium behavior of exclusion processes where agents interact with their nearest neighbors, and we study the short-range correlations which develop becaus…
Modeling tumor cell migration: from microscopic to macroscopic
Christophe Deroulers, Marine Aubert, Mathilde Badoual +1
It has been shown experimentally that contact interactions may influence the migration of cancer cells. Previous works have modelized this thanks to stochastic, discrete models (ce…
