However, the direct impacts of canopy disturbance on the arboreal movement of individual primates have been less studied. Such impacts could shed light on the cascading effects of disturbances on animal health and fitness. Orangutans are an arboreal primate that commonly encounters habitat quality deterioration due to land-use changes and related disturbances such as forest fires. Forest disturbance may, therefore, create a complex stress scenario threatening orangutan populations. Due to forest disturbances, orangutans may adapt to employ more terrestrial, as opposed to arboreal, movements potentially prolonging the search for fruiting and nesting trees. In turn, this may lead to changes in daily activity patterns (i.e., time spent traveling, feeding, and resting) and available energy budget, potentially decreasing the orangutan's fitness. We developed the agent-based simulation model BORNEO (arBOReal aNimal movEment mOdel), which explicitly describes both orangutans' arboreal and terrestrial movement in a forest habitat, depending on distances between trees and canopy structures. Orangutans in the model perform activities with a motivation to balance energy intake and expenditure through locomotion. We tested the model using forest inventory data obtained in Sebangau National Park, Central Kalimantan, Indonesia. This allowed us to construct virtual forests with real characteristics including tree connectivity, thus creating the potential to expand the environmental settings for simulation experiments. In order to parameterize the energy related processes of the orangutans described in the model, we applied a computationally intensive evolutionary algorithm and evaluated the simulation results against observed behavioral patterns of orangutans. Both the simulated variability and proportion of activity budgets including feeding, resting, and traveling time for female and male orangutans confirmed the suitability of the model for its purpose. We used the calibrated model to compare the activity patterns and energy budgets of orangutans in both natural and disturbed forests . The results confirm field observations that orangutans in the disturbed forest are more likely to experience deficit energy balance due to traveling to the detriment of feeding time. Such imbalance is more pronounced in males than in females. The finding of a threshold of forest disturbances that affects a significant change in activity and energy budgets suggests potential threats to the orangutan population. Our study introduces the first agent-based model describing the arboreal movement of primates that can serve as a tool to investigate the direct impact of forest changes and disturbances on the behavior of species such as orangutans. Moreover, it demonstrates the suitability of high-performance computing to optimize the calibration of complex agent-based models describing animal behavior at a fine spatio-temporal scale (1-m and 1-s granularity).", "publicationTitle": "Frontiers in Ecology and Evolution", "volume": "10", "issue": "", "pages": "983337", "date": "2022-9-23", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Front.

Medical experts, however, still need to understand the reasoning behind the predictions before trusting them. In their day-to-day practice, physicians prefer using gene expression profiles, consisting of a discretized subset of all data from gene expressions: in these profiles, genes are typically reported as either over-expressed or under-expressed, using discretization thresholds computed on data from a healthy control group. A discretized profile allows medical experts to quickly categorize patients at a glance. Building on previous works related to the automatic discretization of patient profiles, we present a novel approach that frames the problem as a multi-objective optimization task: on the one hand, after discretization, the medical expert would prefer to have as few different profiles as possible, to be able to classify patients in an intuitive way; on the other hand, the loss of information has to be minimized. Loss of information can be estimated using the performance of a classifier trained on the discretized gene expression levels. We apply one common state-of-the-art evolutionary multi-objective algorithm, NSGA-II, to the discretization of a dataset of COVID-19 patients that developed either mild or severe symptoms. The results show not only that the solutions found by the approach dominate traditional discretization based on statistical analysis and are more generally valid than those obtained through single-objective optimization, but that the candidate Pareto-optimal solutions preserve the sense-making that practitioners find necessary to trust the results.", "date": "2023", "proceedingsTitle": "Applications of Evolutionary Computation", "conferenceName": "", "place": "Cham", "publisher": "Springer Nature Switzerland", "volume": "", "pages": "703-717", "series": "", "language": "en", "DOI": "10.1007/978-3-031-30229-9_45", "ISBN": "978-3-031-30229-9", "shortTitle": "Multi-objective Evolutionary Discretization of Gene Expression Profiles", "url": "", "accessDate": "", "archive": "", "archiveLocation": "", "libraryCatalog": "Springer Link", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "COVID-19", "type": 1 }, { "tag": "Gene Expressions", "type": 1 }, { "tag": "Multi-Objective Evolutionary Algorithms", "type": 1 }, { "tag": "Patient Profiles", "type": 1 } ], "collections": [ "DFIEKF27" ], "relations": {}, "dateAdded": "2024-03-13T08:44:47Z", "dateModified": "2024-03-13T08:44:47Z" } }, { "key": "UDQNQJ3T", "version": 745, "library": { "type": "group", "id": 396913, "name": "iscpif", "links": { "alternate": { "href": "https://www.zotero.org/groups/iscpif", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/396913/items/UDQNQJ3T", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/iscpif/items/UDQNQJ3T", "type": "text/html" } }, "meta": { "createdByUser": { "id": 2562073, "username": "Chatero", "name": "Dacha", "links": { "alternate": { "href": "https://www.zotero.org/chatero", "type": "text/html" } } }, "creatorSummary": "Squillero and Tonda", "parsedDate": "2023-11-22", "numChildren": 0 }, "data": { "key": "UDQNQJ3T", "version": 745, "itemType": "journalArticle", "title": "Veni, Vidi, Evolvi commentary on W.

However, considerable planning challenges are met when confronting the multiple rationalities of involved stakeholders. The SubDense European project aims in that context at better understanding the polyrationalities of space, actors and policies on suburban densification, by exploring how diverse strategies of land policy interact with landowners' and local stakeholders' interest and agency to shape suburban densification and their impact on suburbia across different planning systems (France, Germany, UK). The project combines quantitative approaches (geodata analysis and geosimulation) with qualitative approaches (social and policy science and planning).\nWhen working on such diverse case studies at a large scale, many issues arise, such as how to share analysis and methods for reproduction on other case studies, or how to integrate knowledge on data specification which changes can strongly bias the densification analysis. There is also a need for sharing tools and methods for building change detection, such as polygon matching algorithms. We propose to tackle these difficulties by constructing a collaborative dashboard, which will act as a medium to facilitate collaboration between project partners, will enable the sharing of methods, data and metadata (Bucher et al, 2020), and will allow reproducibility.\nWe use a git-based architecture for the core dashboard to ensure tractability, full history, reproducibility, flexibility, and collaboration through branching and a shared remote repository (https://github.com/subdense). Clients will implement interactions with the core and functionalities needed by partners for data analysis and integration (running change detection algorithms, adding data, exploring results and maps). An iterative process to produce user stories is currently implemented, to finally lead to final specifications for the core architecture and functionalities of clients. A first version of the dashboard has already been deployed, through which partners have shared first densification analysis and data expertises.\nFuture developments and analysis to be integrated through the dashboard will include heterogeneous data integration (Bucher et al., 2021), to couple densification analysis with socio-economic data, and the development and exploration of simulation models for the impact of policies on densification processes. These models will act as bridges between quantitative analysis and the qualitative data obtained through interviews during the project.\n\nReferences\n\nBucher, B., Tiainen, E., Ellett von Brasch, T., Janssen, P., Kotzinos, D., Čeh, M. & Zhral, M.

Innovation dynamics in social and technological systems are strongly linked to urban systems and their multi-scale properties. Understanding underlying processes is crucial for sustainable territorial planning. We introduce a multi-scalar model for innovation dynamics in systems of cities, coupling a macroscopic innovation diffusion and urban dynamics model with mesoscopic models for local innovation clusters.

In our work, we treat misinformation with a structural and dynamic\napproach which focuses on context rather than on content. Our contributions are\nmostly tools relying on network information flow and its relation to social structures\nto inform the detection of anomalous user accounts. Our methods are validated\ncontemporary online data, namely three Twitter datasets collected over the last few\nyears regarding discourse on global warming, French politics, and vaccination.\nWe first focus on community dynamics. A distinction is made between intra-\ncommunity dynamics, studied using a novel method based on Markov chains, and\ninter-community dynamics analyzed via alluvial patterns that reveal online commu-\nnities. The general temporal evolution of a social graph is also modeled by Deep\nLearning with Temporal Graph Networks. These are augmented with a novel reliabil-\nity module in order to detect graph anomalies and thus online coordination. This\nmodeling permits a deeper understanding of general social network evolution, and\nespecially the rise of political polarization. Our analysis highlights the role played\nby communities and individual users in information propagation, both exhibiting\ncharacteristic patterns.\nWe evaluate the impact of misinformation by examining agenda-setting and\nnetwork reconfiguration. We analyze how information propagation is re-purposed\nfor agenda-setting, and especially in political agenda-setting. We describe several\nlevels of agenda-setting with techniques based on time-series correlations of activity,\ninspired from existing methods in neurology. We have developed another method\nbased on link prediction in graphs to quantify the extent to which topics such as\nCOVID-19 predict political reconfiguration.\nThe above methods are used to highlight real disinformation campaigns and\ntheir consequences.

In this paper, we address the question identifying the branches of science by taking advantage of the massive digitization of scientific production. In the framework of complex systems studies, we first formalize the notion of level and scale of knowledge dynamics. Then, we demonstrate how we can reconstruct a reasonably precise and concise multi-scale and multi-level approximation of the dynamical structures of Science: phylomemies. We introduce the notion of phylomemetic networks—projections of phylomemies in low dimensional spaces that can be grasped by the human mind—and propose a new algorithm to reconstruct both phylomemies and the associated phylomemetic networks. This algorithm offers, passing, a new temporal clustering on evolving semantic networks. Last, we show how phylomemy reconstruction can take into account users’ preferences within the framework of embodied cognition, thus defining a third way between the quest for objective “ground truth” and the ad-hoc adaptation to a particular user’s preferences.

disinformation becomes increasingly important. Given current volumes of data, automated approaches for the detection of disinformation are the only ones able to offer an online solution. We formalize disinformation as an anomaly in the organic evolution of the network, in terms of users, content or coordination. To identify it, we propose a solution based on Temporal Graph Networks (TGN) adapted to the detection of anomalies and completed with a reliability module which permits users to trade precision for recall. Inheriting the performances of TGN, this solution is able to scale up, work on continuous time settings, and handle multimodality (text, image and video). Moreover, when compared to existing models, our approach outperforms state-of-the-art solutions for anomaly detection in dynamic graphs on several classical datasets.

Indeed, social division occurs not only offline but also online on various political topics or scientific controversies. Several studies propose tools to identify and quantify online controversies through stance detection or polarization measures. While polarization is typically studied as a \"snapshot\" in time of a social network, we consider it as a temporal process. Moreover, the recent evolution in temporal graph representation learning provides new tools to directly combine time, content and graph topology. Current techniques that characterize polarization are beginning to use these tools, typically using a Lagrangian description which focuses on user trajectories. In this article, we make a case for approaching these problems with a Eulerian description, the concurrent description in fluid mechanics. In this description, the temporal evolution of nodes embeddings is represented with a deformation of velocity vector fields.

As early as the late 1970s, internal studies by the fossil fuel industries made accurate projections linking global warming to CO2 emissions, predicting at the same time \"dramatic environmental effects to come before the year 2050\". Meanwhile, these same companies, especially ExxonMobil, tried to convince the public that it was impossible to establish a causal link between fossil fuel use and global warming because the models used to model climate response were too uncertain. Since the 1970s, advances in climate science have provided an increasingly clear statement of the reality of global warming (see IPCC Group I report, Chapter 1), while the 2021 IPCC report states that \"there is unequivocal evidence that human influence has warmed the atmosphere, ocean and land.\" As global warming intensifies in every region of the world (the year 2022 being emblematic) and its impacts worsen, this decade is critical to resolutely engage in a decrease of greenhouse gas emissions. Despite this, we are witnessing an intensification of the activity of online denialist and climate-skeptic groups and an upward revision of the emission targets of most of the oil majors that have just announced record annual profits (e.g. BP). In France, the intensification of denialist activism has been particularly marked since July 2022, with a triple climate-related news: a series of extreme events, the holding of COP27 with a strong presence of fossil fuel industries, and finally the convergence of global warming issues with those of the security of oil and gas supply due to the war in Ukraine. This study describes some of the strategies implemented by climate skeptic and denialist activists on Twitter to gain influence, quantifies their effects and highlights potential geopolitical motivations alongside the political and economic dimensions already present. It relies on methodologies developed at the CNRS at CAMS and at the Institut des Systèmes Complexes in Paris. Beyond \"fact-checking\", this study aims at a better understanding of the circulation of different narratives related to climate change and in particular those related to disinformation.", "genre": "", "repository": "HAL Science", "archiveID": "hal-04103183", "place": "", "date": "2023/05/23", "series": "", "seriesNumber": "", "DOI": "", "citationKey": "", "url": "https://hal.science/hal-04103183", "accessDate": "2023-05-23T07:28:11Z", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "hal.science", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "DFIEKF27" ], "relations": {}, "dateAdded": "2024-03-13T08:07:25Z", "dateModified": "2024-03-13T08:07:25Z" } }, { "key": "HXAWJCAV", "version": 726, "library": { "type": "group", "id": 396913, "name": "iscpif", "links": { "alternate": { "href": "https://www.zotero.org/groups/iscpif", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/396913/items/HXAWJCAV", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/iscpif/items/HXAWJCAV", "type": "text/html" } }, "meta": { "createdByUser": { "id": 2562073, "username": "Chatero", "name": "Dacha", "links": { "alternate": { "href": "https://www.zotero.org/chatero", "type": "text/html" } } }, "creatorSummary": "Lobbé et al.", "parsedDate": "2023-12-31", "numChildren": 0 }, "data": { "key": "HXAWJCAV", "version": 726, "itemType": "bookSection", "title": "Defining Level and Scale as Socio-technical Operators for Mining Digital Traces", "creators": [ { "creatorType": "author", "firstName": "Quentin", "lastName": "Lobbé" }, { "creatorType": "author", "firstName": "David", "lastName": "Chavalarias" }, { "creatorType": "author", "firstName": "Alexandre", "lastName": "Delanoë" } ], "abstractNote": "Defining Level and Scale as Socio-technical Operators for Mining Digital Traces was published in Zoomland on page 407.", "bookTitle": "Defining Level and Scale as Socio-technical Operators for Mining Digital Traces", "series": "", "seriesNumber": "", "volume": "", "numberOfVolumes": "", "edition": "", "place": "", "publisher": "De Gruyter Oldenbourg", "date": "2023-12-31", "pages": "407-426", "language": "en", "ISBN": "978-3-11-131777-9", "shortTitle": "", "url": "https://www.degruyter.com/document/doi/10.1515/9783111317779-015/html", "accessDate": "2023-12-20T10:06:50Z", "archive": "", "archiveLocation": "", "libraryCatalog": "www.degruyter.com", "callNumber": "", "rights": "De Gruyter expressly reserves the right to use all content for commercial text and data mining within the meaning of Section 44b of the German Copyright Act.", "extra": "DOI: 10.1515/9783111317779-015", "tags": [], "collections": [ "DFIEKF27" ], "relations": {}, "dateAdded": "2024-03-13T08:07:25Z", "dateModified": "2024-03-13T08:07:25Z" } } ]
