Spatial scaling of network length and shared-node density in bilayer distribution grids
Emile Emery, José Halloy
Certain distribution networks are built in layers, each layer collecting a commodity from the layer above it and delivering it to the layer below. We propose a minimal model that g…
Connecting Electrical Grid Length and Material Stock to Population Density: Comparison of a French-Calibrated Scaling with 35 Electrified Countries
Emile Emery, Joseph Le Bihan, José Halloy
The expansion of global electricity distribution systems necessitates the deployment of massive infrastructure. Assessing its implications from a spatial and material perspective r…
The Physics of Sustainability: Material and Power Constraints for the Long Term
José Halloy, Petros Chatzimpiros, François Graner +1
Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energ…
Beyond 2050: From deployment to renewal of the global solar and wind energy system
Joseph Le Bihan, Thomas Lapi, José Halloy
The global energy transition depends on large-scale photovoltaic (PV) and wind power deployment. While 2050 targets suggest a transition endpoint, maintaining these systems beyond…
Modeling Technological Deployment and Renewal: Monotonic vs. Oscillating Industrial Dynamics
Joseph Le Bihan, Thomas Lapi, José Halloy
This study proposes a new model based on a classic S-curve that describes deployment and stabilization at maximum capacity. In addition, the model extends to the post-growth platea…
Investor-patent networks as mutualistic networks
Théophile Carniel, Léo Cazenille, Jean-Michel Dalle +1
Venture capital investments in startups have come to represent an important driver of technological innovation, in parallel to corporate- and government-directed efforts. Part of t…
Applicability of Hubbert model to global mining industry: Interpretations and insights
Lucas Riondet, Daniel Suchet, Olivier Vidal +1
The Hubert's model has been introduced in 1956 as a phenomenological description of the time evolution of US oil fields production. It has since then acquired a vast notoriety as a…
Tracing the origins of SARS-CoV-2 in coronavirus phylogenies
Erwan Sallard, José Halloy, Didier Casane +2
SARS-CoV-2 is a new human coronavirus (CoV), which emerged in China in late 2019 and is responsible for the global COVID-19 pandemic that caused more than 59 million infections and…
Automatic Calibration of Artificial Neural Networks for Zebrafish Collective Behaviours using a Quality Diversity Algorithm
Leo Cazenille, Nicolas Bredeche, José Halloy
During the last two decades, various models have been proposed for fish collective motion. These models are mainly developed to decipher the biological mechanisms of social interac…
Modelling zebrafish collective behaviours with multilayer perceptrons optimised by evolutionary algorithms
Leo Cazenille, Nicolas Bredeche, José Halloy
Collective movements are pervasive behaviours among social organisms and have led to the development of many models. However, modelling animal trajectories and social interactions…
Evolutionary optimisation of neural network models for fish collective behaviours in mixed groups of robots and zebrafish
Leo Cazenille, Nicolas Bredeche, José Halloy
Animal and robot social interactions are interesting both for ethological studies and robotics. On the one hand, the robots can be tools and models to analyse animal collective beh…
How to Blend a Robot within a Group of Zebrafish: Achieving Social Acceptance through Real-time Calibration of a Multi-level Behavioural Model
Leo Cazenille, Yohann Chemtob, Frank Bonnet +4
We have previously shown how to socially integrate a fish robot into a group of zebrafish thanks to biomimetic behavioural models. The models have to be calibrated on experimental…
Loose social organisation of AB strain zebrafish groups in a two-patch environment
Axel Séguret, Bertrand Collignon, Leo Cazenille +2
We explore the collective behaviours of 7 group sizes: 1, 2, 3, 5, 7, 10 and 20 AB zebrafish (Danio rerio) in a constraint environment composed of two identical squared rooms conne…
Collective departures in zebrafish: profiling the initiators
Bertrand Collignon, Axel Séguret, Yohann Chemtob +2
For animals living in groups, one of the important questions is to understand what are the decision-making mechanisms that lead to choosing a motion direction or leaving an area wh…
Automated optimisation of multi-level models of collective behaviour in a mixed society of animals and robots
Leo Cazenille, Nicolas Bredeche, José Halloy
Animal and robotic collective behaviours can exhibit complex dynamics that require multi-level descriptions. Here, we are interested in developing a multi-level modeling framework…
Strains differences in the collective behaviour of zebrafish (Danio rerio) in heterogeneous environment
Axel Séguret, Bertrand Collignon, José Halloy
Recent studies show differences in individual motion and shoaling tendency between strains of the same species. Here, we analyse the collective motion and the response to visual st…
Automated Analysis of Behavioural Variability and Filial Imprinting of Chicks (G. gallus), using Autonomous Robots
A. Gribovskiy, F. Mondada, J. L. Deneubourg +3
Inter-individual variability has various impacts in animal social behaviour. This implies that not only collective behaviours have to be studied but also the behavioural variabilit…
Zebrafish collective behaviour in heterogeneous environment modeled by a stochastic model based on visual perception
Bertrand Collignon, Axel Séguret, José Halloy
Collective motion is one of the most ubiquitous behaviours displayed by social organisms and has led to the development of numerous models. Recent advances in the understanding of…
The Nosoi commute: a spatial perspective on the rise of BSL-4 laboratories in cities
Thomas P. Van Boeckel, Michael J. Tildesley, Catherine Linard +3
Recent H5N1 influenza research has revived the debate on the storage and manipulation of potentially harmful pathogens. In the last two decades, new high biosafety (BSL-4) laborato…
