accessibility. These characteristics give rise to hierarchical structures, where structural changes emerge at distinct scales. In this talk, we propose a multiscalar, relational framework for detecting these shifts and identifying scale-specific vulnerabilities in accessibility. This work reveals leverage points for targeted, resilience-oriented interventions.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section

spread of infectious diseases, providing useful insights to applied public health. To be actionable, models need to be informed by data that describe the structure of interactions between individuals. While data coming from different sources and at different resolutions have become increasingly available, their integration into computational frameworks poses a number of challenges.<\/p>\n<p class=\"part\" data-startline=\"55\" data-endline=\"55\">I will first give an example of how high resolution data sets can be used to build realistic agent-based models, suggest, evaluate and compare various mitigation strategies. As such detailed data sets are however rarely available, I will also discuss whether models fed with less detailed data lead to the same actionable conclusions. Finally, while most studies focus on how the structure of contacts shapes the spread of a disease, I will address a reverse question: do different spreading processes unfolding on a network lead to the same propagation patterns? This has consequences in the role of models in decision-making, as many results on propagation patterns and on the identification of structures with high spreading power or to monitor in surveillance programs are typically obtained using very simplified contagion processes. Our results imply in particular that numerical simulations using simplified settings can bring important insights even in the case of a new emerging disease whose properties are not yet well known. I will conclude with some perspectives on new avenues in the modeling of spreading phenomena.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section

itemprop=\"text\" ><p>Current Large Language Models (LLMs) have opened new avenues for modeling complex social dynamics. In particular, LLM-driven agents provide a unique opportunity to explore several phenomena in artificial societies. Admittedly, recent advancements have demonstrated that LLMs can exhibit human-like behaviors, including cooperation, fairness, and adherence to social norms. However, they also present significant challenges, such as sensitivity to prompt design, hallucinations, and inconsistencies in decision-making. In this talk, we discuss the capacity of GABMs to reproduce behavioral experiments and compare findings on cooperation and reputation dynamics in human groups with those obtained by implementing a reputation-based game in which LLM-driven agents played the Prisoner&#8217;s Dilemma on dynamics networks. Our results indicate that LLM-based agents can partially reproduce human cooperative behavior and network dynamics, though important limitations remain. These models will become increasingly integrated into decision-making processes, thus, understanding their constraints and interaction patterns with humans and artificial agents is crucial.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-m83c6462-6c84b6bc446e4431267da10dfba7a333'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-12' data-fake-id='#toggle-id-12' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-12' data-slide-speed=\"200\" data-title=\"Website\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Website\" data-aria_expanded=\"Click to collapse: Website\">Website<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-12' aria-labelledby='toggle-toggle-id-12' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color '  itemprop=\"text\" ><div class='avia-iframe-wrap'>\n<blockquote class=\"wp-embedded-content\" data-secret=\"7ll3SyViYc\">\n<p><a href=\"https:\/\/cosnet.bifi.es\/people\/yamir-moreno\/\">Prof. Yamir Moreno (Group Leader)<\/a><\/p>\n<\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00abProf. Yamir Moreno (Group Leader)\u00bb \u2014 Cosnet\" src=\"https:\/\/cosnet.bifi.es\/people\/yamir-moreno\/embed\/#?secret=G5TDZQz5c6#?secret=7ll3SyViYc\" data-secret=\"7ll3SyViYc\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/div>\n<\/div><\/div><\/div><\/section>\n<\/div><\/p><\/div>\n<div  class='flex_column av-1a2tyi-782eaf35fbc173cafcae3340eebf840c av_one_third  avia-builder-el-25  el_after_av_two_third  el_before_av_two_third  first flex_column_div  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-m7t9qf3p-d99c45b13fdd4709a7f737cd1a74db42\">\n.avia-image-container.av-m7t9qf3p-d99c45b13fdd4709a7f737cd1a74db42 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-m7t9qf3p-d99c45b13fdd4709a7f737cd1a74db42 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-m7t9qf3p-d99c45b13fdd4709a7f737cd1a74db42 av-styling-circle avia-align-center  avia-builder-el-26  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-478 avia-img-lazy-loading-not-478 avia_image ' src=\"https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/03\/Camille_Roth-180x180.jpg\" alt='' title='Camille_Roth'  height=\"180\" width=\"180\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/03\/Camille_Roth-180x180.jpg 180w, https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/03\/Camille_Roth-80x80.jpg 80w, https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/03\/Camille_Roth-36x36.jpg 36w\" sizes=\"(max-width: 180px) 100vw, 180px\" \/><\/div><\/div><\/div><\/div>\n<div  class='flex_column av-1j4gya-e5cc5374f5fc1cdc6bbacc386b529e9b av_two_third  avia-builder-el-27  el_after_av_one_third  el_before_av_one_third  flex_column_div  column-top-margin'     ><section  class='av_textblock_section av-1cvnl6-f4c8a7715dcb6d098fd88803938d19dd '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h2 style=\"text-align: left;\"><strong>CAMILLE ROTH<\/strong><\/h2>\n<p style=\"text-align: left;\">CNRS &#038; EHESS, Centre d&#8217;analyse et de math\u00e9matique sociales, Paris, France<\/p>\n<\/div><\/section><br \/>\n<div  class='togglecontainer av-19hb9m-bf9f5d45352edd3191f726367ee5810a  avia-builder-el-29  el_after_av_textblock  avia-builder-el-last  toggle_close_all' >\n<section class='av_toggle_section av-12y57u-666571c92354a1c1d8607c14b48fab25'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-13' data-fake-id='#toggle-id-13' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-13' data-slide-speed=\"200\" data-title=\" Echo chambers, filter bubbles?

Are they ubiquitous in social media? It might depend on which data one is looking at. At a more macro level, is the notion of online fragmentation, or the co-existence of communities between which there are few bridges, at odds with the idea that online spaces foster global arenas ? It might also depend on how data is filtered. The term of filter bubbles describes the possibility that algorithmic personalization would confine users to consumption of content they are most comfortable with. Is it a necessary behavior of recommendation algorithms? Again, it might depend. We will review these three connected contemporary debates on the social dynamics of online communities, whereby the literature appears to bring conflicting results and where, we argue, the way data are being appraised may play a key role.\u00a0<\/span><\/div>\n<\/div>\n<div>\n<div><\/div>\n<\/div>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section

more than 5 decades. While the understanding of the relation between diversity and the stability of properties at community and ecosystem levels has gained from joint empirical, experimental and theoretical insights, the question of the relation between food web structure and stability has received almost exclusively theoretical attention. The lack of empirical studies on this issue is partly due to the fact that theoretical studies are often disconnected from the stability of natural ecosystems, and to the difficulty of describing and manipulating food web structure in the field. Here I will present results based on both theoretical food web models and data analyses of time-series of fish communities across France, aiming to investigate in parallel the relations between diversity, food web structure and the stability of ecosystem properties.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-m83cbapa-e4bfceccec4c317a26eb03ab1925beb7'

In particular, the evolution of non-coding genome size is still poorly understood: While some fraction of non-coding DNA has arguably a regulatory function, a large part does not seem to have a detectable impact on any phenotypic trait and the abundance of non-functional DNA in genomes, observed across the Tree of Life, challenges a purely adaptationist explanation. In this talk, I will present several computational and mathematical models we build to study the dynamics of non-coding sequences in the presence of various kinds of mutational events including substitutions, InDels and structural variants. I will show how the non-coding fraction of the genome is shaped by two factors: unavoidable biases in the neutrality of the different mutation types and the robustness selection imposed by the mere existence of structural variants. I will show how these two factors together ensure the existence of an equilibrium non-coding fraction and that \u2014 at least in the models \u2014 this equilibrium depends solely on the product of population size and mutation rate.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-m83crkjt-4063de3fc134d746c5490490e7fa11f2'

networks and hypergraphs to generate realistic surrogates induces us to reflect about the set of intrinsic relationships that shape an evolving network. These involve temporal and topological causalities and correlations concerning nodes activity and hyperedges appearance. We observe how the individual nodes dynamics is linked to that of neighbouring nodes but is also influenced by the global topology. Analogously, the local topology at each time is affected both by the interactions of the few previous time steps and by long-term temporal correlations. In this context we develop a framework to generate temporal networks and hypergraphs, both based on the observation of real-world temporal networks given as input. This methodology will allow to obtain surrogate temporal networks or hypergraphs to replace real data when the latter are not usable or sharable (particularly useful for social data, often subject to privacy issues). It additionally provides an important tool for data augmentation, allowing us to generate temporal networks with an arbitrary number of nodes and time span, using as input original patterns extracted from available datasets of limited size. The versatility of the obtained methods allows us to combine multiple input temporal networks, for instance different social contexts, thus simulating a complete society resulting from the integration of different social settings (e.g., schools, workplaces, hospitals, etc.). This represents an additional mechanism to overcome the incompleteness of original data.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section

A common expectation is that people consulting numerous pieces of information, well balancing the different sides of an issue, will adopt a moderate attitude about the issue. We claim that this expectation is deceitful and suggest that, on the contrary, people tend to get extreme and dogmatic. The cause for this extremization is a hardening confirmation bias&#8212;when their attitude gets more extreme, people get more likely to ignore information that differs from their views. Our claim is supported by simulations of two fundamentally different computational models of an agent consulting information and holding a hardening confirmation bias. For both models, the initially moderate attitude of the agent tends to get extreme when the agent consults abundant unbiased information, while it remains moderate when consulting limited information. We analyze the extremization pathways displayed in the models and discuss how our results may affect views on polarization and on the role of online media.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-m83cir19-ab1f863dbe859185407fee96dbedaa92'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\"

lang=\"FR\">The existence of large language models makes it possible to imagine new ways of looking at language change. But much can still be done by using existing language corpora and models of language change. For instance, looking at changes in frequency alone, it has been shown that it is possible to identify ongoing language change, e.g. the competition between variants, which displays a characteristic \u2018s-curve\u2019. This concept is anything but new (Osgood &#038; Sebeok 1954, Kroch 1989), but has been recently refined theoretically with more explicit models (Blythe &#038; Croft 2012, Feltgen et al. 2017, Feltgen 2024), and used to identify cases of language change in large corpora (Boukhaled et al. 2019). A crucial question in that respect is whether it can be used not only to identify language change, but to distinguish between different types of change (viz. lexical innovation, borrowing, calques, grammaticalization). In my talk, I will address this question with data from large diachronic corpora.<\/span><\/p>\n<p class=\"x_MsoNormal\"><span lang=\"FR\">References<\/span><\/p>\n<p class=\"x_MsoNormal\">Blythe, R.

Thus, a profound understanding of the morphology and dynamics of road network evolution can significantly support territorial planning.<\/span><\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-ma6sthm9-91302b6371d88b329a6800df9270286d'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-35' data-fake-id='#toggle-id-35' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-35' data-slide-speed=\"200\" data-title=\"Abstract\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Abstract\" data-aria_expanded=\"Click to collapse: Abstract\">Abstract<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-35' aria-labelledby='toggle-toggle-id-35' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color '  itemprop=\"text\" ><p class=\"x_MsoNormal\">tba<\/p>\n<p class=\"x_MsoNormal\">\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-ma6suayh-3055d55e05218be62cc77226e9cc71e4'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-36' data-fake-id='#toggle-id-36' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-36' data-slide-speed=\"200\" data-title=\"Website\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Website\" data-aria_expanded=\"Click to collapse: Website\">Website<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-36' aria-labelledby='toggle-toggle-id-36' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color '  itemprop=\"text\" ><p><a href=\"https:\/\/thema.univ-fcomte.fr\/page_personnelle\/clagesse\">https:\/\/thema.univ-fcomte.fr\/page_personnelle\/clagesse<\/a><\/p>\n<\/div><\/div><\/div><\/section>\n<\/div><\/p><\/div>\n<div  class='flex_column av-fjtwy-ebea37d7ee80409005696d15228417eb av_one_third  avia-builder-el-67  el_after_av_two_third  el_before_av_two_third  first flex_column_div  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-m9idiqr4-10b5835f09459d9054a9b918e5ef4bc9\">\n.avia-image-container.av-m9idiqr4-10b5835f09459d9054a9b918e5ef4bc9 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-m9idiqr4-10b5835f09459d9054a9b918e5ef4bc9 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-m9idiqr4-10b5835f09459d9054a9b918e5ef4bc9 av-styling-circle avia-align-center  avia-builder-el-68  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-564 avia-img-lazy-loading-not-564 avia_image ' src=\"https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/04\/Pedro_Ramaciotti-180x180.png\" alt='' title='Pedro_Ramaciotti'  height=\"180\" width=\"180\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/04\/Pedro_Ramaciotti-180x180.png 180w, https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/04\/Pedro_Ramaciotti-80x80.png 80w, https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/04\/Pedro_Ramaciotti-36x36.png 36w\" sizes=\"(max-width: 180px) 100vw, 180px\" \/><\/div><\/div><\/div><\/div>\n<div  class='flex_column av-8otxu-e0f78b07fb18090e74c6f9110aec0e8f av_two_third  avia-builder-el-69  el_after_av_one_third  el_before_av_one_third  flex_column_div  column-top-margin'     ><section  class='av_textblock_section av-m9idjt47-f580bf8e889e1fe46f99bffc711067ea '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h2 style=\"text-align: left;\"><strong>PEDRO RAMACIOTTI MORALES\u00a0<\/strong><\/h2>\n<p style=\"text-align: left;\">Complex Systems Institute of Paris &#038;

One leading type of concern regards phenomena such as informational segregation or polarisation. Numerous studies have addressed these questions at national level and on different platforms, but essential questions remain unanswered regarding the measurement and prevalence of these phenomena. One outstanding challenge is the comparative measurement of polarisation in reference frames that can be applied across national settings and time-frames. In this talk I explore how conceptual frameworks from sociology and political science\u2013that have guided decades of advances in survey-based research\u2013extend to the study of these online spaces, enabling the study of polarisation in multidimensional issue and ideology space, and on a multitude of countries and settings, from the study of algorithmic recommendation, to media outlet ecosystems, and online political mobilisation.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-m9idkvd7-cd04b719843fd07100764be3d2abe176'  itemscope=\"itemscope\"

In my thesis, I used a physics-informed machine learning framework under low-data, partial-knowledge conditions to show that self-organization drives the formation of regular nanometric surface patterns under femtosecond laser irradiation. To build on this work, it is crucial to establish a precise link between complexity and self-organization. In this talk, I present a novel measure of dynamic complexity for self-organized systems that integrates dynamical diversity and connectivity. This metric is straightforward to implement, efficient to compute, and applies across scales \u2014 from convective nanometric patterns to the large-scale structures of the universe \u2014 demonstrating its versatility and intuitive appeal, potentially across disciplines.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-570h6y-9e028f7aef1c2e0e4dbf2abea28f8093'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-45' data-fake-id='#toggle-id-45' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-45' data-slide-speed=\"200\" data-title=\"biography\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: biography\" data-aria_expanded=\"Click to collapse: biography\">biography<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-45' aria-labelledby='toggle-toggle-id-45' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color '  itemprop=\"text\" ><p class=\"part\" data-startline=\"9\" data-endline=\"9\">PhD, Laboratoire Hubert Curien (2023, Saint-\u00c9tienne, France).

The complex organization of this structure suggests the presence of an underlying order in urban evolution. Among the urban components, road networks endure through time, and present a challenging yet fascinating subject for study. Graph theory offers a mathematical formalization of road networks, enhancing spatial understanding.<br \/>\nOur research approaches urban morphology through an analytical lens focused on road networks, emphasizing historical context and structural features induced by their physical layout. It unfolds in three axes: (1) morpho-historical analyses of road networks in Dijon, Besan\u00e7on, and Pontarlier, over time, revealing common structural properties ; (2) identification of morphotypes within the road network, associated with morphological evolution processes ; and (3) proposing simulation model, namely \u201cWayMorph\u201d.<br \/>\nThe fundings reveals that urban morphology is the result of complex processes that can be identified by analyzing spatial structure.Understanding urban morphogenesis and past evolution is pivotal for addressing future developmental challenges, aiding decision-making for city stakeholders. Territorial development choices, reflected in road network morphologies, reciprocally influence accessibility disparities and territorial development dynamics. Profound comprehension of road network evolution dynamics can significantly support territorial planning.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-36qchu-b5fe6a85394c6939ee3411823231fc0a'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-51' data-fake-id='#toggle-id-51' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-51' data-slide-speed=\"200\" data-title=\"Biography\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Biography\" data-aria_expanded=\"Click to collapse: Biography\">Biography<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-51' aria-labelledby='toggle-toggle-id-51' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color '  itemprop=\"text\" ><p>PhD (2023) and currently a research associate at Th\u00e9MA Laboratory (Besan\u00e7on)<br \/>\n<a href=\"https:\/\/thema.univ-fcomte.fr\/page_personnelle\/hanae\" target=\"_blank\" rel=\"noopener\">https:\/\/thema.univ-fcomte.fr\/page_personnelle\/hanae<\/a><\/p>\n<\/div><\/div><\/div><\/section>\n<\/div><\/p><\/div><div  class='flex_column av-31n5l6-cbc6ae4b538d97e057b59154e261fdf2 av_one_third  avia-builder-el-94  el_after_av_two_third  el_before_av_two_third  first flex_column_div  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mawfty8m-fe7c8690ea592c4bbc56f42040cf65df\">\n.avia-image-container.av-mawfty8m-fe7c8690ea592c4bbc56f42040cf65df img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-mawfty8m-fe7c8690ea592c4bbc56f42040cf65df .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-mawfty8m-fe7c8690ea592c4bbc56f42040cf65df av-styling-circle avia-align-center  avia-builder-el-95  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-676 avia-img-lazy-loading-not-676 avia_image ' src=\"https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/05\/Jeammet-Selenne-180x180.png\" alt='' title='Jeammet S\u00e9l\u00e8nne'  height=\"180\" width=\"180\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/05\/Jeammet-Selenne-180x180.png 180w, https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/05\/Jeammet-Selenne-80x80.png 80w, https:\/\/conferences.css-fr.org\/wp-content\/uploads\/2025\/05\/Jeammet-Selenne-36x36.png 36w\" sizes=\"(max-width: 180px) 100vw, 180px\" \/><\/div><\/div><\/div><\/div><\/p>\n<div  class='flex_column av-a8682-aae44fcca84a8601d60d17feb9ac5e8a av_two_third  avia-builder-el-96  el_after_av_one_third  el_before_av_one_third  flex_column_div  column-top-margin'     ><section  class='av_textblock_section av-mawe1w1k-f9f297f957047310dcd1a34fe6014e03 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h2 style=\"text-align: left;\"><strong>Jeammet S\u00e9l\u00e8nne<\/strong><\/h2>\n<p style=\"text-align: left;\">Morphog\u00e9n\u00e8se de r\u00e9seaux dans l\u2019argile<\/p>\n<\/div><\/section><br \/>\n<div  class='togglecontainer av-2pdsp6-763c75ab633f4b171b03729cb9d96d91  avia-builder-el-98  el_after_av_textblock  avia-builder-el-last  toggle_close_all' >\n<section class='av_toggle_section av-2jjlki-3ce9488ccb20572421a7fb46388483e0'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-52' data-fake-id='#toggle-id-52' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-52' data-slide-speed=\"200\" data-title=\"Ruptures enlac\u00e9es -

Quand ces argiles se dess\u00e8chent, par \u00e9vaporation \u00e0 la surface en contact avec l\u2019air, elles cherchent alors \u00e0 se r\u00e9tracter. L\u2019argile \u00e0 la surface va se d\u00e9former, augmentant les contraintes, jusqu\u2019\u00e0 un seuil de rupture, o\u00f9 des craquelures apparaissent pour relaxer les contraintes accumul\u00e9es dans le mat\u00e9riau. Ces craquelures se propagent, interagissent, se rencontrent, et finissent par former une structure complexe de r\u00e9seau spatial \u00e0 la surface.<\/p>\n<p class=\"part\" data-startline=\"38\" data-endline=\"38\">Ces structures rencontr\u00e9es dans les sols peuvent \u00eatre reproduites en laboratoire, en laissant une couche d\u2019argile mince, initialement humidifi\u00e9e, se dess\u00e9cher sur des plaques de verres, en faisant varier les conditions exp\u00e9rimentales (\u00e9paisseur, type d\u2019argile, humidit\u00e9 de l\u2019air, temp\u00e9rature) et en observant les variations de motifs occasionn\u00e9es. Ce syst\u00e8me est peu co\u00fbteux, et permet d\u2019obtenir des motifs vari\u00e9s dont on peut suivre l\u2019\u00e9volution sur des temps raisonnables. Il constitue donc un syst\u00e8me pratique pour l\u2019\u00e9tude de l\u2019apparition de r\u00e9seaux spatiaux, dans la continuit\u00e9 de travaux sur ces structures apparaissant dans d\u2019autres syst\u00e8mes, comme les veines des frondes de foug\u00e8res, les rues dans les villes, les squelettes de coraux.<\/p>\n<p class=\"part\" data-startline=\"40\" data-endline=\"40\">Dans une approche morphog\u00e9n\u00e9tique, on a propos\u00e9 de comprendre l\u2019apparition de ces motifs par la propagation locale des craquelures. Pour se faire, on a construit un mod\u00e8le ph\u00e9nom\u00e9nologique du syst\u00e8me, bas\u00e9 sur nos observations des exp\u00e9riences, en mod\u00e9lisant les ingr\u00e9dients minimaux qui composent ce syst\u00e8me et lui donnent sa complexit\u00e9. De ce mod\u00e8le, on a d\u00e9riv\u00e9 une loi de vitesse pour les craquelures, qui permet de simuler des trajectoires et comportements observ\u00e9s dans les exp\u00e9riences. Par des bifurcations de ces comportements, on peut ainsi remonter de l\u2019\u00e9chelle locale aux motifs globaux, et ainsi comprendre, par l\u2019histoire et les conditions de la croissance, l\u2019\u00e9mergence des diff\u00e9rents types de motifs observ\u00e9s. Ce travail se termine par une ouverture vers les autres syst\u00e8mes physiques exhibant des structures de r\u00e9seaux spatiaux en deux dimensions, en adaptant le mod\u00e8le construit pour les craquelures \u00e0 ces syst\u00e8mes. On a ainsi propos\u00e9 une classification des structures de r\u00e9seaux spatiaux en fonction du type de potentiel dans lequel ces r\u00e9seaux croissent, en exhibant notamment la possibilit\u00e9 de transitions entre r\u00e9seaux r\u00e9ticul\u00e9s et non-r\u00e9ticul\u00e9s, traditionnellement per\u00e7us comme qualitativement distincts.<\/p>\n<\/div><\/div><\/div><\/section>\n<section

reshape how the whole group talks about colors. But how do such individual variations influence the emergence of shared communication systems? In this talk, I explore how differences in language production and perception can influence how languages evolve. To test this, we conducted a laboratory experiment in which small groups of four participants developed a shared language, with one participant deliberately biased in their communication. Then, we also used Bayesian agent-based models to explore how a shared language emerges in heterogeneous groups, and how the structure of the communicative networks influences these dynamics. The results challenge the common assumption that \u2018majority rules\u2019 and suggest that languages are adjusted to the unique characteristics of their speakers, even if they are in the minority. My goal is to bring a nuanced understanding of language evolution, treating variation as valuable data rather than mere noise.<\/p>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-7wjf6-a5c8992c4bdaaef9b3c60942501b62f0'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-57' data-fake-id='#toggle-id-57' class='toggler  av-title-above '  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-57' data-slide-speed=\"200\" data-title=\"Biography\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Biography\" data-aria_expanded=\"Click to collapse: Biography\">Biography<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-57' aria-labelledby='toggle-toggle-id-57' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color '  itemprop=\"text\" ><p>Cognitive scientist exploring language evolution &#038; cross-cultural psychology.
