    The ICTRP Search Portal aims to provide a single point of access to information about ongoing and completed clinical trials. It provides a searchable database containing the trial registration data sets made available by data providers around the world meeting criteria for content and quality control.

    Trial registration data sets are available on the ICTRP Search Portal in English only. Some data providers, however, may also store trial registration data sets in other languages. If available, these may be searched by going directly to the web sites of the individual registries. It is possible to search for trials registered in certain Primary Registries in the following languages:

    Chinese - Chinese Clinical Trial Registry (ChiCTR)
    Dutch - The Netherlands National Trial Register (NTR)
    German – German Clinical Trials Register (DRKS)
    Japanese – Japan Primary Registries Network (JPRN)
    Korean – Clinical Research Information Service (CRiS), Republic of Korea
    Persian – Iranian Registry of Clinical Trials (IRCT)
    Portuguese – Brazilian Registry of Clinical Trials (ReBec)
    Spanish – Cuban Public Registry of Clinical Trials(RPCEC) and the Peruvian Clinical Trial Registry (REPEC)

    To facilitate the unambiguous identification of trials, the Search Portal bridges (groups together) multiple records about the same trial.

    The ICTRP Search Portal has been developed to make it easier for users to search for clinical trials. Please contact us if you have any comments or suggestions.

    And we would like to thank the many hundreds of you who give us feedback on this work every day.
    Your feedback is what allows us to continuously clarify and improve it. We very much appreciate you taking the time to write.
    Even if we can’t respond to every message we receive, we do read all feedback and take it all into account.

    Note: To inform yourself and understand the risk to the public we recommend to rely on your government body responsible for health and the World Health Organization – their site is here.

    The mission of Our World in Data is to make data and research on the world’s largest problems understandable and accessible.

    Read more about our mission →

    Only on the basis of clearly presented and well-documented data can governments, organizations and individuals hope to respond appropriately to the COVID-19 pandemic. The goal of our work here is to present the best available data and clarify what can – and can not be said – based on this data.

    We list all our visualizations – more than 40 in total – on the pandemic on this page.

    This article covers a developing situation and the Our World in Data team is updating it daily: The last update was made on April 4, 2020 (11:30, London time).
    Summary

    Even the best existing research and data is preliminary and will be revised as the pandemic progresses.
    We reviewed existing global data sources and decided to rely on the global statistics published by the European Center for Disease Prevention and Control (ECDC).

    Deaths
    During a disease outbreak it is the growth rate that deserves attention. We present a table that lists how fast the number of deaths is doubling.
    In interactive charts we present the data on confirmed deaths in all countries in the world.

    Testing
    Without widespread testing for COVID-19 we can neither know how the pandemic is spreading nor appropriately respond to it.

    Cases
    The total number of COVID-19 cases is not known. It is however certain that the total number of COVID-19 cases is higher than the number of known confirmed cases. This is mainly due to limited testing.
    Just as we do for deaths, we focus on the growth rate of confirmed cases. We present a sortable table that lists how fast the number of confirmed cases is doubling.
    In interactive charts we present the data on confirmed cases over time in all countries in the world.

    Mortality
    The case fatality rate (CFR) – the ratio between confirmed deaths and cases – is widely discussed, but during the outbreak of a pandemic with large unknowns it is important to know what can and cannot be said based on currently available statistics.

    We rely on data from the European CDC

    In this document and the many embedded and linked charts we report and visualize the data from the European Center for Disease Prevention and Control (ECDC).

    The European CDC publishes daily statistics on the COVID-19 pandemic. Not just for Europe, but for the entire world.

    The ECDC makes all their data available in a daily updated clean downloadable file. This gets updated daily reflecting data collected up to 6:00 and 10:00 CET. The data made public via the downloadable data file is published at 1pm CET, and is used to produce a page that gets updated daily under the name Situation Update Worldwide.

    We discuss our data sources and why we rely on the data from the ECDC rather than other institutions at the end of this article here.
    Reported new cases on a particular day do not necessarily represent new cases on that day

    The number of confirmed cases or deaths reported by any institution – including the WHO, the ECDC, Johns Hopkins and others – on a given day does not represent the actual number of new cases or deaths on that date. This is because of the long reporting chain that exists between a new case or death, and its inclusion in national or international statistics.

    The steps in this chain are different across countries, but for many countries the reporting chain includes most of the following steps:1

    Doctor or laboratory diagnoses a COVID-19 case based on testing or combination of symptoms and epidemiological probability (such as a close family member testing positive).
    Doctor or laboratory submits report to health department of the city or local district.
    Health department receives the report and records each individual case in the reporting system, including patient information.
    The ministry or another governmental organization brings this data together and publishes the latest figures.
    International data bodies such as the WHO or the ECDC can then collate statistics from hundreds of such national accounts.

    This reporting chain can take several days. This is why the figures reported on any given date do not necessarily reflect the number of new cases or deaths on that specific date.

    Polymath proposal: clearinghouse for crowdsourcing COVID-19 data and data cleaning requests
    OFFICIAL WEBSITE Terry Tao BLOG

    25 March, 2020 in math.ST, polymath | Tags: Chris Strohmeier, coronavirus

    After some discussion with the applied math research groups here at UCLA (in particular the groups led by Andrea Bertozzi and Deanna Needell), one of the members of these groups, Chris Strohmeier, has produced a proposal for a Polymath project to crowdsource in a single repository (a) a collection of public data sets relating to the COVID-19 pandemic, (b) requests for such data sets, (c) requests for data cleaning of such sets, and (d) submissions of cleaned data sets. (The proposal can be viewed as a PDF, and is also available on Overleaf). As mentioned in the proposal, this database would be slightly different in focus than existing data sets such as the COVID-19 data sets hosted on Kaggle, with a focus on producing high quality cleaned data sets. (Another relevant data set that I am aware of is the SafeGraph aggregated foot traffic data, although this data set, while open, is not quite public as it requires a non-commercial agreement to execute. Feel free to mention further relevant data sets in the comments.)

    This seems like a very interesting and timely proposal to me and I would like to open it up for discussion, for instance by proposing some seed requests for data and data cleaning and to discuss possible platforms that such a repository could be built on. In the spirit of “building the plane while flying it”, one could begin by creating a basic github repository as a prototype and use the comments in this blog post to handle requests, and then migrate to a more high quality platform once it becomes clear what direction this project might move in. (For instance one might eventually move beyond data cleaning to more sophisticated types of data analysis.)

    UPDATE, Mar 25: a prototype page for such a clearinghouse is now up at this wiki page.

    UPDATE, Mar 27: the data cleaning aspect of this project largely duplicates the existing efforts at the United against COVID-19 project, so we are redirecting requests of this type to that project (and specifically to their data discourse page). The polymath proposal will now refocus on crowdsourcing a list of public data sets relating to the COVID-19 pandemic.

    COVID-19 Open Research Dataset Challenge (CORD-19) An AI challenge with AI2, CZI, MSR, Georgetown, NIH & The White House
    WEBSITE - DATA

    Dataset Description

    In response to the COVID-19 pandemic, the White House and a coalition of leading research groups have prepared the COVID-19 Open Research Dataset (CORD-19). CORD-19 is a resource of over 47,000 scholarly articles, including over 36,000 with full text, about COVID-19, SARS-CoV-2, and related coronaviruses. This freely available dataset is provided to the global research community to apply recent advances in natural language processing and other AI techniques to generate new insights in support of the ongoing fight against this infectious disease. There is a growing urgency for these approaches because of the rapid acceleration in new coronavirus literature, making it difficult for the medical research community to keep up.

    Call to Action

    We are issuing a call to action to the world's artificial intelligence experts to develop text and data mining tools that can help the medical community develop answers to high priority scientific questions. The CORD-19 dataset represents the most extensive machine-readable coronavirus literature collection available for data mining to date. This allows the worldwide AI research community the opportunity to apply text and data mining approaches to find answers to questions within, and connect insights across, this content in support of the ongoing COVID-19 response efforts worldwide. There is a growing urgency for these approaches because of the rapid increase in coronavirus literature, making it difficult for the medical community to keep up.

    A list of our initial key questions can be found under the Tasks section of this dataset. These key scientific questions are drawn from the NASEM’s SCIED (National Academies of Sciences, Engineering, and Medicine’s Standing Committee on Emerging Infectious Diseases and 21st Century Health Threats) research topics and the World Health Organization’s R&D Blueprint for COVID-19.

    Many of these questions are suitable for text mining, and we encourage researchers to develop text mining tools to provide insights on these questions.

    We are maintaining a summary of the community's contributions. For guidance on how to make your contributions useful, we're maintaining a forum thread with the feedback we're getting from the medical and health policy communities.
    Prizes

    Kaggle is sponsoring a $1,000 per task award to the winner whose submission is identified as best meeting the evaluation criteria. The winner may elect to receive this award as a charitable donation to COVID-19 relief/research efforts or as a monetary payment. More details on the prizes and timeline can be found on the discussion post.

    Accessing the Dataset

    We have made this dataset available on Kaggle. Watch out for periodic updates.

    The dataset is also hosted on AI2's Semantic Scholar. And you can search the dataset using AI2's new COVID-19 explorer.

    The licenses for each dataset can be found in the all _ sources _ metadata csv file.

    Welcome from the Chair
    The concept of entropy emerges initially from the scope of physics, but it is now clear that entropy is deeply related to information theory and the process of inference. Today, entropic techniques have found a broad spectrum of applications in all branches of science.

    The conference will be organized into six sessions, which reflect the inter-disciplinary nature of entropy and its applications:

    • Statistical Physics
    • Information Theory, Probability and Statistics
    • Thermodynamics
    • Quantum Information and Foundations
    • Complex Systems
    • Entropy in Multidisciplinary Applications

    The inter-disciplinary and multi-disciplinary nature of contributions from both theoretical and applied perspectives are welcome, including papers addressing conceptual and methodological developments, as well as new applications of entropy and information theory.

    All accepted abstracts will be published in the proceedings of the conference. Moreover, participants are cordially invited to contribute with a full manuscript to Entropy Special Issue "Entropy: The Scientific Tool of the 21st Century".

    Special Issue Submission deadline: 30 October 2020
    Papers presented at the conference will be granted a 30% discount!

    The conference is sponsored by MDPI, the publisher of the open-access journal Entropy and follows the very successful meeting Entropy 2018: From Physics to Information Sciences and Geometry held in May 2018 in Barcelona, Spain.

    We very much look forward to seeing you at this exciting meeting in Porto.

    =====================================
    PhD opening at the University of Groningen
    =====================================

    The group of Probability and Statistics at the University of Groningen invites applications for a

    4-year PhD position

    During your PhD you will work at the forefront of research in topological data analysis and spatial random networks. While the previous years have brought forth outstanding progress in the description of large combinatorial random graphs, the understanding of random structures with spatial dependencies is still in its infancy. A key component of your research will be to identify regimes that are amenable to a rigorous mathematical description in terms of central limit theorems and large deviation principles.

    Modern materials science is a major driving force behind the interest in topological data analysis and spatial random networks, since the insights gained from appropriate mathematical models make it possible to reduce the number of time-consuming experiments. With the newly established CogniGron, the University of Groningen has created an interdisciplinary research center with the goal of making progress towards cognitive computing. Hence, you will have the unique opportunity to interact broadly with colleagues outside mathematics. You will also be expected to contribute to the teaching at the faculty.

    Hence, if you have graduated with an outstanding Master's degree (or are about to do so soon) and are committed to working on fundamental research questions, we are very much looking forward to your application. Any background knowledge in large deviation theory, random networks or central limit theorems will help you to get a smoother start.

    We offer a full-time PhD position for 4 years. The salary and working hours are determined according to the Collective Labour Agreement for Dutch Universities. In 2019, PhD candidates started with € 2,325 gross per month; for a candidate in the fourth year, this figure rises to € 2,972. In addition to that, the salary scheme comprised 8% of the yearly salary as holiday bonus and 8.3% as end of your bonus.

    We are an equal opportunity employer that values diversity. We have adopted an active policy to increase the number of female scientists across all disciplines of the university.

    We envision that you join us on April 1, 2020 or later. Please send us until January 27, 2020 your cover letter, CV, Master's thesis (or a preliminary version) and transcript of records. All documents should be sent to dr. Christian Hirsch: c.p.hirsch@rug.nl, who will also be happy to answer your questions on the position.

    W3. Complex Networks: Hidden Geometry and Dynamics
    Workshop organized by: B. Tadic and N. Gupteo

    The influence of network structure on dynamics in many complex systems has been demonstrated in numerous studies with a detailed analysis of empirical data and theoretical approaches. Recent studies of networks representing various complex systems from the brain to large-scale social dynamics have revealed their higher-order architecture, which can be described as aggregates of simplexes (triangles, tetrahedrons, and higher cliques). Beyond the standard graph theory, these hidden structures are quantified by algebraic topology methods. This Special Session will bring together presentations exploring different complex systems concerning a) the structure of simplicial complexes, including the properties of the underlying topological graph (network); b) dynamic processes in a particular or co-evolving network structure; c) information topology and graph representations of time series. We expect research results based on empirical data analysis and theoretical and numerical modeling. The aim is to cover recent developments in these areas of research and to stimulate discussion towards an in-depth understanding of the role of higher-order connectivity in the emergence of functional properties of complex systems.

    S3. Information Geometry and Deformed Statistics
    Special Session organized by J. Zhang and H. Matsuzoe

    Information geometry provides a suite of differential geometric tools for studying statistical inference, information theory, and machine learning models. Key notions such as statistical manifolds (with Fisher information as to its Riemannian metric), Hessian geometry, biorthogonal coordinates have links to statistical mechanics, thermodynamics, geometric mechanics, etc. As sequel to the special session (organized by Johnston, Matsuzoe, Ruppeiner, and Wada) at SigmaPhi2017, this Session at SigmaPhi2020 will explore differential geometric characterizations of probabilistic models arising from a variety of setting including stochastic thermodynamics, condensed matter physics, cosmology and high-energy physics, etc. Of particular interest are deformed statistical models, models which deviate from exponential family through parameterization (e.g., kappa-exponential model, q-exponential model, Renyi model) and their associated deformed entropy, cross-entropy, and divergences. The Session will also welcome contributions from related disciplines of statistical machine learning, dynamics and control, optimal transport and Wasserstein geometry, etc.

    Scientific rationale:
    In the middle of the last century, Léon Brillouin in "The Science and The Theory of Information" or André Blanc-Lapierre in "Statistical Mechanics" forged the first links between the Theory of Information and Statistical Physics as precursors. In the context of Artificial Intelligence, machine learning algorithms use more and more methodological tools coming from the Physics or the Statistical Mechanics. The laws and principles that underpin this Physics can shed new light on the conceptual basis of Artificial Intelligence. Thus, the principles of Maximum Entropy, Minimum of Free Energy, Gibbs-Duhem's Thermodynamic Potentials and the generalization of François Massieu's notions of characteristic functions enrich the variational formalism of machine learning. Conversely, the pitfalls encountered by Artificial Intelligence to extend its application domains, question the foundations of Statistical Physics, such as the construction of stochastic gradient in large dimension, the generalization of the notions of Gibbs densities in spaces of more elaborate representation like data on homogeneous differential or symplectic manifolds, Lie groups, graphs, tensors, .... Sophisticated statistical models were introduced very early to deal with unsupervised learning tasks related to Ising-Potts models (the Ising-Potts model defines the interaction of spins arranged on a graph) of Statistical Physics. and more generally the Markov fields. The Ising models are associated with the theory of Mean Fields (study of systems with complex interactions through simplified models in which the action of the complete network on an actor is summarized by a single mean interaction in the sense of the mean field). The porosity between the two disciplines has been established since the birth of Artificial Intelligence with the use of Boltzmann machines and the problem of robust methods for calculating partition function. More recently, gradient algorithms for neural network learning use large-scale robust extensions of the natural gradient of Fisher-based Information Geometry (to ensure reparameterization invariance), and stochastic gradient based on the Langevin equation (to ensure regularization), or their coupling called "Natural Langevin Dynamics". Concomitantly, during the last fifty years, Statistical Physics has been the object of new geometrical formalizations (contact or symplectic geometry, ...) to try to give a new covariant formalization to the thermodynamics of dynamic systems. We can mention the extension of the symplectic models of Geometric Mechanics to Statistical Mechanics, or other developments such as Random Mechanics, Geometric Mechanics in its Stochastic version, Lie Groups Thermodynamic, and geometric modeling of phase transition phenomena. Finally, we refer to Computational Statistical Physics, which uses efficient numerical methods for large-scale sampling and multimodal probability measurements (sampling of Boltzmann-Gibbs measurements and calculations of free energy, metastable dynamics and rare events, ...) and the study of geometric integrators (Hamiltonian dynamics, symplectic integrators, ...) with good properties of covariances and stability (use of symmetries, preservation of invariants, ...). Machine learning inference processes are just beginning to adapt these new integration schemes and their remarkable stability properties to increasingly abstract data representation spaces. Artificial Intelligence currently uses only a very limited portion of the conceptual and methodological tools of Statistical Physics. The purpose of this conference is to encourage constructive dialogue around a common foundation, to allow the establishment of new principles and laws governing the two disciplines in a unified approach. But, it is also about exploring new « chemins de traverse ».
