artificial intelligence systems becoming ubiquitous in our society, its designers will soon have to start to consider its social dimension, as many of these systems will have to interact among them to work efficiently. With this in mind, we propose a decentralized deep reinforcement learning algorithm for the design of cooperative multi-agent systems. The algorithm is based on the hypothesis that highly correlated actions are a feature of cooperative systems, and hence, we propose the insertion of an auxiliary objective of maximization of the mutual information between the actions of agents in the learning problem. Our system is applied to a social dilemma, a problem whose optimal solution requires that agents cooperate to maximize a macroscopic performance function despite the divergent individual objectives of each agent. By comparing the performance of the proposed system to a system without the auxiliary objective, we conclude that the maximization of mutual information among agents promotes the emergence of cooperation in social dilemmas.","publication_date":{"day":21,"month":6,"year":2020,"errors":{}},"grobid_abstract_attachment_id":94302584},"translated_abstract":null,"internal_url":"https://www.academia.edu/90855838/Emergent_cooperation_through_mutual_information_maximization","translated_internal_url":"","created_at":"2022-11-15T11:55:48.097-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":94302584,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302584/thumbnails/1.jpg","file_name":"2006.11769.pdf","download_url":"https://www.academia.edu/attachments/94302584/download_file?st=MTczMjc0MzIyMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Emergent_cooperation_through_mutual_info.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302584/2006.11769-libre.pdf?1668542894=\u0026response-content-disposition=attachment%3B+filename%3DEmergent_cooperation_through_mutual_info.pdf\u0026Expires=1732746820\u0026Signature=U0DYqGqlNtxjCgZTjg6ZtibQC~hgJoqCD0jJarN1ImwNQqNd9gsGWTq6LdC6-iKxpGIW5Fi8CvC27bx-u0LFyrpjeiajjOjidIehMKRjjHucYV5KcDKrVxGcQDLbN7Uu4NcrO1q2Sv7IMG~4SMPuYbkoD6l5jIc97F3m~OsLvYS7xuiAC0DgXUhawBy~HfYP6Gnmi0O8kC2IqGE1J1FmfNOTVpCUygB~-~piNKZ~Yjy7EZcUgmonvcBRptv3JPOiSdIwIbdhluaVARQIWf62mjXykjw4pWqdsO5FfDfh~j0yVkb5k-s4G-TL4vR4zD3zBZe4Decj7Lj6bkLZA8Ih-w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Emergent_cooperation_through_mutual_information_maximization","translated_slug":"","page_count":20,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago

defined in terms of low-level ones. In this paper we explore self-supervised learning of hierarchical representations of speech by applying multiple levels of Contrastive Predictive Coding (CPC). We observe that simply stacking two CPC models does not yield significant improvements over single-level architectures. Inspired by the fact that speech is often described as a sequence of discrete units unevenly distributed in time, we propose a model in which the output of a low-level CPC module is non-uniformly downsampled to directly minimize the loss of a high-level CPC module. The latter is designed to also enforce a prior of separability and discreteness in its representations by enforcing dissimilarity of successive high-level representations through focused negative sampling, and by quantization of the prediction targets. Accounting for the structure of the speech signal improves upon single-level CPC features and enhances the disentanglement of the learned representations, as measured by downstream speech recognition tasks, while resulting in a meaningful segmentation of the signal that closely resembles phone boundaries.

The proposed algorithm is based on solving a set of surrogate problems defined by models of the real one, so that only solutions estimated to be approximately Pareto-optimal are evaluated using the real expensive functions. Aside of the search for solutions, our algorithm also performs a meta-search for optimal surrogate models and navigation strategies for the optimization landscape, therefore adapting the search strategy for solutions to the problem as new information about it is obtained. The competitiveness of our approach is demonstrated by an experimental comparison with one state-of-the-art surrogate-assisted evolutionary algorithm on a set of benchmark

hydrolytic up-flow sludge blanket (HUSB) reactor and constructed wetlands (CW). The WETWINE plant is located in Tomino (Pontevedra, Spain) and is being validated at the demo-scale at Santiago Ruiz Winery (NW Spain). The plant consisted of a HUSB reactor for removing suspended solids and hydrolyse organic matter, followed by two vertical subsurface flow constructed wetland (VF) operating in parallel and to provide further treatment, a horizontal subsurface flow constructed wetland (HF) operating in series. After two years of continuous monitoring and regardless in the variation of flow and load, the hybrid system achieved average removal efficiencies of over 93% for total suspended solids and chemical oxygen demand, receiving an overall surface loading of up to 115 g COD/m2·d.

The use of different packing materials including a mixture of pine bark, perlite and compost for the organic biofilter and polyurethane foam for the inorganic one was evaluated. The influence of other major variables on the removal efficiency such as nutrient requirements, operational conditions and long-term stability were also assessed in both configurations. The analysis of the biofilters operation proved that both configurations provided a feasible and stable performance in the treatment of diffuse methane emissions. Once the operational feasibility of both systems was proved, the environmental assessment was performed. The main hotspots found in the analysis were attributed to the requirement of nutrients, infrastructure, waste disposal and direct emissions to the atmosphere. A sensitivity analysis was performed in terms of nutrient supply and infrastructure material which revealed that special attention needs to be paid to the formulation of the nutrient solution in terms of concentration and source of nitrogen.","publication_date":{"day":null,"month":null,"year":2017,"errors":{}},"publication_name":"Journal of Cleaner Production","grobid_abstract_attachment_id":94302608},"translated_abstract":null,"internal_url":"https://www.academia.edu/90855818/Diffuse_methane_emissions_abatement_by_organic_and_inorganic_packed_biofilters_Assessment_of_operational_and_environmental_indicators","translated_internal_url":"","created_at":"2022-11-15T11:55:22.761-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":94302608,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302608/thumbnails/1.jpg","file_name":"j.jclepro.2016.11.18520221115-1-1e0g4d0.pdf","download_url":"https://www.academia.edu/attachments/94302608/download_file?st=MTczMjc0MzIyMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diffuse_methane_emissions_abatement_by_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302608/j.jclepro.2016.11.18520221115-1-1e0g4d0-libre.pdf?1668542723=\u0026response-content-disposition=attachment%3B+filename%3DDiffuse_methane_emissions_abatement_by_o.pdf\u0026Expires=1732746820\u0026Signature=Lul6HHcKimiIMK90obSob2WoxXuv4iiJdr4rt9ifXcc~NaAlStUzk2TYW6iKxRIT1nqLhdtUlqnYgBwel~TIFAV1L0K-O0o1mHWmTD5R8ARTEF6bFNLVttair6V0cHiSqnxN4R08f30RdBGT0rOsAQw6~~gVcD4a3LLRMZdxc0d6ekFXazmuXvYY158ruzKDYI3kb7V9e5SvpvlMPtbGeuB6Vcx2GYXWUTLUN3xR36QZNJDbe0lzJbkvyHp9MOa-by0NYHNSgLDumipBEX2JcyBMqU8VzNeElpQsWwGpjPq1SNO43lGmiRq9HksRim-0jo~-JySMTNQHV4hQ0YYmiQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Diffuse_methane_emissions_abatement_by_organic_and_inorganic_packed_biofilters_Assessment_of_operational_and_environmental_indicators","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago Cuervo","url":"https://independent.academia.edu/SantiagoCuervo19"},"attachments":[{"id":94302608,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302608/thumbnails/1.jpg","file_name":"j.jclepro.2016.11.18520221115-1-1e0g4d0.pdf","download_url":"https://www.academia.edu/attachments/94302608/download_file?st=MTczMjc0MzIyMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diffuse_methane_emissions_abatement_by_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302608/j.jclepro.2016.11.18520221115-1-1e0g4d0-libre.pdf?1668542723=\u0026response-content-disposition=attachment%3B+filename%3DDiffuse_methane_emissions_abatement_by_o.pdf\u0026Expires=1732746820\u0026Signature=Lul6HHcKimiIMK90obSob2WoxXuv4iiJdr4rt9ifXcc~NaAlStUzk2TYW6iKxRIT1nqLhdtUlqnYgBwel~TIFAV1L0K-O0o1mHWmTD5R8ARTEF6bFNLVttair6V0cHiSqnxN4R08f30RdBGT0rOsAQw6~~gVcD4a3LLRMZdxc0d6ekFXazmuXvYY158ruzKDYI3kb7V9e5SvpvlMPtbGeuB6Vcx2GYXWUTLUN3xR36QZNJDbe0lzJbkvyHp9MOa-by0NYHNSgLDumipBEX2JcyBMqU8VzNeElpQsWwGpjPq1SNO43lGmiRq9HksRim-0jo~-JySMTNQHV4hQ0YYmiQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":55,"name":"Environmental Engineering","url":"https://www.academia.edu/Documents/in/Environmental_Engineering"},{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":1584,"name":"Cleaner Production","url":"https://www.academia.edu/Documents/in/Cleaner_Production"},{"id":14085,"name":"Waste Management","url":"https://www.academia.edu/Documents/in/Waste_Management"},{"id":96825,"name":"Manufacturing Engineering","url":"https://www.academia.edu/Documents/in/Manufacturing_Engineering"},{"id":337999,"name":"Perlite","url":"https://www.academia.edu/Documents/in/Perlite"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering"},{"id":555091,"name":"Compost","url":"https://www.academia.edu/Documents/in/Compost"},{"id":743608,"name":"Biofilter","url":"https://www.academia.edu/Documents/in/Biofilter"}],"urls":[{"id":26007888,"url":"https://api.elsevier.com/content/article/PII:S0959652616320479?httpAccept=text/plain"}]}, dispatcherData: dispatcherData });

Results indicate interesting links between the performance of the biofilter and the presence of extracellular polysaccharide and protein concentration in the liquid phase, with increasing concentrations detected when the process was not stable.","internal_url":"https://www.academia.edu/90855814/EPS_and_SMP_as_Stability_Indicators_During_the_Biofiltration_of_Diffuse_Methane_Emissions","translated_internal_url":"","created_at":"2022-11-15T11:55:14.372-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[],"slug":"EPS_and_SMP_as_Stability_Indicators_During_the_Biofiltration_of_Diffuse_Methane_Emissions","translated_slug":"","page_count":null,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago Cuervo","url":"https://independent.academia.edu/SantiagoCuervo19"},"attachments":[],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":156347,"name":"Methane","url":"https://www.academia.edu/Documents/in/Methane"},{"id":743608,"name":"Biofilter","url":"https://www.academia.edu/Documents/in/Biofilter"}],"urls":[{"id":26007886,"url":"http://link.springer.com/content/pdf/10.1007/s11270-015-2576-2.pdf"}]}, dispatcherData: dispatcherData });

The operation at ambient temperature implies higher methane content in the liquid anaerobic effluent, which finally causes concentrations around 0.01-2.4% in the off-gas released in the anoxic-aerobic chamber (1.25% average). Mass balances indicate that these emissions account for up to 30-35% of the total methane generated in the anaerobic reactor. A conventional biofilter (BF) operated at an empty bed residence time of 4 min was used to treat these emissions for 70 d. In spite of the fluctuations in the methane inlet concentrations derived from the operation of the wastewater treatment plant (WWTP), it was possible to operate at pseudo-steady-state conditions, achieving average removal efficiencies of 76.5% and maximum elimination capacities of 30.1 g m −3 h −1. Odour removal was quantified as 99.1%. Fluorescence in situ hybridization probes as well as metabolic activity assays demonstrated the suitability of the biomass developed in the WWTP as inoculum to start up the BF due to the presence of methanotrophic bacteria.","publication_date":{"day":null,"month":null,"year":2015,"errors":{}},"publication_name":"Environmental

Among activities included in a long-term initiative to ascertain which are the fascioliasis areas of most concern, studies were performed in a recreational farm, including liver fluke infection in different domestic animal species, classification of the lymnaeid vector and verification of natural transmission of fascioliasis by identification of the intramolluscan trematode larval stages found in naturally infected snails. The high prevalences in the domestic animals appeared related to only one lymnaeid species present. Lymnaeid and trematode classification was verified by means of nuclear ribosomal DNA and mitochondrial DNA marker sequencing. Complete sequences of 18S rRNA gene and rDNA ITS-2 and ITS-1, and a fragment of the mtDNA cox1 gene demonstrate that the Argentinian lymnaeid belongs to the species Lymnaea neotropica. Redial larval stages found in a L. neotropica specimen were ascribed to Fasciola hepatica after analysis of the complete ITS-1 sequence. The finding of L. neotropica is the first of this lymnaeid species not only in Argentina but also in Southern Cone countries. The total absence of nucleotide differences between the sequences of specimens from Argentina and the specimens from the Peruvian type locality at the levels of rDNA 18S, ITS-2 and ITS-1, and the only one mutation at the mtDNA cox1 gene suggest a very recent spread. The ecological characteristics of this lymnaeid, living in small, superficial water collections frequented by livestock, suggest that it may be carried from one place to another by remaining in dried mud stuck to the feet of transported animals. The presence of L. neotropica adds pronounced complexity to the transmission and epidemiology of fascioliasis in Argentina, due to the great difficulties in distinguishing, by traditional malacological methods, between the three similar lymnaeid species of the controversial Galba/Fossaria group present in this country: L. viatrix, Galba truncatula and L. neotropica. It also poses a problem with regard to the use, for lymnaeid vector species discrimination, of several molecular techniques which do not show sufficient accuracy, as those relying on the 18S rRNA gene or parts of it, because both L. neotropica and L. viatrix present identical 18S sequence.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="90855811"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="90855811"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 90855811; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=90855811]").text(description); $(".js-view-count[data-work-id=90855811]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 90855811; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='90855811']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 90855811, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=90855811]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":90855811,"title":"Fascioliasis transmission by Lymnaea neotropica confirmed by nuclear rDNA and mtDNA sequencing in Argentina","translated_title":"","metadata":{"abstract":"Fascioliasis is widespread in livestock in Argentina.

learning (SSL) methods based on Contrastive Predictive Coding (CPC). Our experiments show that with the existing algorithms there is a trade off between categorization and segmentation performance. We investigate the source of this conflict and conclude that the use of context building networks, albeit necessary for superior performance on categorization tasks, harms segmentation performance by causing a temporal shift on the learned representations. Aiming to bridge this gap, we take inspiration from the leading approach on segmentation, which simultaneously models the speech signal at the frame and phoneme level, and incorporate multi-level modelling into Aligned CPC (ACPC), a variation of CPC which exhibits the best performance on categorization tasks. Our multi-level ACPC (mACPC) improves in all categorization metrics and achieves state-of-the-art performance in word segmentation.","publication_name":"ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)","grobid_abstract_attachment_id":94302544},"translated_abstract":null,"internal_url":"https://www.academia.edu/90855738/Contrastive_Prediction_Strategies_for_Unsupervised_Segmentation_and_Categorization_of_Phonemes_and_Words","translated_internal_url":"","created_at":"2022-11-15T11:52:58.045-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":94302544,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302544/thumbnails/1.jpg","file_name":"2110.15909v1.pdf","download_url":"https://www.academia.edu/attachments/94302544/download_file?st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Contrastive_Prediction_Strategies_for_Un.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302544/2110.15909v1-libre.pdf?1668542715=\u0026response-content-disposition=attachment%3B+filename%3DContrastive_Prediction_Strategies_for_Un.pdf\u0026Expires=1732746821\u0026Signature=FknxfCda3rcq0aejE833QvN0COLA6L3XRXHiXgRzW6nMlhbSruxD5UM1euqC2xNcgzayrjsoCHS8aDxRGJHQWY2vG9bSxTMcKYjGu989y0S19qWZXnbcKYEARwfjjsfdqiUkDqJ9T7q5WZyM6C0Yhz9crZwyiGxNnQPi6HotgoR~8rAqbgNLzkNuKQqFL0q9jrBlqQVFYM69sMBLapFt5hPWGA9swiws06LsWl-eRVwFMIkolHvXyuXgi3JgQ8EJW1C8XTnHUZmzi4M0q1CY7WPNzBuY8HuWBzaK7zBPftWGO-N2ocmShnA0AJVRuiJTAXTvH74rIyTcEgIWUtKHBA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Contrastive_Prediction_Strategies_for_Unsupervised_Segmentation_and_Categorization_of_Phonemes_and_Words","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago Cuervo","url":"https://independent.academia.edu/SantiagoCuervo19"},"attachments":[{"id":94302544,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302544/thumbnails/1.jpg","file_name":"2110.15909v1.pdf","download_url":"https://www.academia.edu/attachments/94302544/download_file?st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Contrastive_Prediction_Strategies_for_Un.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302544/2110.15909v1-libre.pdf?1668542715=\u0026response-content-disposition=attachment%3B+filename%3DContrastive_Prediction_Strategies_for_Un.pdf\u0026Expires=1732746821\u0026Signature=FknxfCda3rcq0aejE833QvN0COLA6L3XRXHiXgRzW6nMlhbSruxD5UM1euqC2xNcgzayrjsoCHS8aDxRGJHQWY2vG9bSxTMcKYjGu989y0S19qWZXnbcKYEARwfjjsfdqiUkDqJ9T7q5WZyM6C0Yhz9crZwyiGxNnQPi6HotgoR~8rAqbgNLzkNuKQqFL0q9jrBlqQVFYM69sMBLapFt5hPWGA9swiws06LsWl-eRVwFMIkolHvXyuXgi3JgQ8EJW1C8XTnHUZmzi4M0q1CY7WPNzBuY8HuWBzaK7zBPftWGO-N2ocmShnA0AJVRuiJTAXTvH74rIyTcEgIWUtKHBA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science"},{"id":465,"name":"Artificial Intelligence","url":"https://www.academia.edu/Documents/in/Artificial_Intelligence"},{"id":11984,"name":"Speech Recognition","url":"https://www.academia.edu/Documents/in/Speech_Recognition"},{"id":18573,"name":"Categorization","url":"https://www.academia.edu/Documents/in/Categorization"},{"id":93217,"name":"Segmentation","url":"https://www.academia.edu/Documents/in/Segmentation"},{"id":3193313,"name":"arXiv","url":"https://www.academia.edu/Documents/in/arXiv"}],"urls":[{"id":26007843,"url":"http://xplorestaging.ieee.org/ielx7/9745891/9746004/09746102.pdf?arnumber=9746102"}]}, dispatcherData: dispatcherData });

With this in mind, we propose a decentralized deep reinforcement learning algorithm for the design of cooperative multi-agent systems. The algorithm is based on the hypothesis that highly correlated actions are a feature of cooperative systems, and hence, we propose the insertion of an auxiliary objective of maximization of the mutual information between the actions of agents in the learning problem. Our system is applied to a social dilemma, a problem whose optimal solution requires that agents cooperate to maximize a macroscopic performance function despite the divergent individual objectives of each agent. By comparing the performance of the proposed system to a system without the auxiliary objective, we conclude that the maximization of mutual information among agents promotes the emergence of

defined in terms of low-level ones. In this paper we explore self-supervised learning of hierarchical representations of speech by applying multiple levels of Contrastive Predictive Coding (CPC). We observe that simply stacking two CPC models does not yield significant improvements over single-level architectures. Inspired by the fact that speech is often described as a sequence of discrete units unevenly distributed in time, we propose a model in which the output of a low-level CPC module is non-uniformly downsampled to directly minimize the loss of a high-level CPC module. The latter is designed to also enforce a prior of separability and discreteness in its representations by enforcing dissimilarity of successive high-level representations through focused negative sampling, and by quantization of the prediction targets. Accounting for the structure of the speech signal improves upon single-level CPC features and enhances the disentanglement of the learned representations, as measured by downstream speech recognition tasks, while resulting in a meaningful segmentation of the signal that closely resembles phone boundaries.

The WETWINE plant is located in Tomino (Pontevedra, Spain) and is being validated at the demo-scale at Santiago Ruiz Winery (NW Spain). The plant consisted of a HUSB reactor for removing suspended solids and hydrolyse organic matter, followed by two vertical subsurface flow constructed wetland (VF) operating in parallel and to provide further treatment, a horizontal subsurface flow constructed wetland (HF) operating in series. After two years of continuous monitoring and regardless in the variation of flow and load, the hybrid system achieved average removal efficiencies of over 93% for total suspended solids and chemical oxygen demand, receiving an overall surface loading of up to 115 g COD/m2·d.

The use of different packing materials including a mixture of pine bark, perlite and compost for the organic biofilter and polyurethane foam for the inorganic one was evaluated. The influence of other major variables on the removal efficiency such as nutrient requirements, operational conditions and long-term stability were also assessed in both configurations. The analysis of the biofilters operation proved that both configurations provided a feasible and stable performance in the treatment of diffuse methane emissions. Once the operational feasibility of both systems was proved, the environmental assessment was performed. The main hotspots found in the analysis were attributed to the requirement of nutrients, infrastructure, waste disposal and direct emissions to the atmosphere. A sensitivity analysis was performed in terms of nutrient supply and infrastructure material which revealed that special attention needs to be paid to the formulation of the nutrient solution in terms of concentration and source of nitrogen.","publication_date":{"day":null,"month":null,"year":2017,"errors":{}},"publication_name":"Journal of Cleaner Production","grobid_abstract_attachment_id":94302608},"translated_abstract":null,"internal_url":"https://www.academia.edu/90855818/Diffuse_methane_emissions_abatement_by_organic_and_inorganic_packed_biofilters_Assessment_of_operational_and_environmental_indicators","translated_internal_url":"","created_at":"2022-11-15T11:55:22.761-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":94302608,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302608/thumbnails/1.jpg","file_name":"j.jclepro.2016.11.18520221115-1-1e0g4d0.pdf","download_url":"https://www.academia.edu/attachments/94302608/download_file?st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&st=MTczMjc0MzIyMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diffuse_methane_emissions_abatement_by_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302608/j.jclepro.2016.11.18520221115-1-1e0g4d0-libre.pdf?1668542723=\u0026response-content-disposition=attachment%3B+filename%3DDiffuse_methane_emissions_abatement_by_o.pdf\u0026Expires=1732746820\u0026Signature=Lul6HHcKimiIMK90obSob2WoxXuv4iiJdr4rt9ifXcc~NaAlStUzk2TYW6iKxRIT1nqLhdtUlqnYgBwel~TIFAV1L0K-O0o1mHWmTD5R8ARTEF6bFNLVttair6V0cHiSqnxN4R08f30RdBGT0rOsAQw6~~gVcD4a3LLRMZdxc0d6ekFXazmuXvYY158ruzKDYI3kb7V9e5SvpvlMPtbGeuB6Vcx2GYXWUTLUN3xR36QZNJDbe0lzJbkvyHp9MOa-by0NYHNSgLDumipBEX2JcyBMqU8VzNeElpQsWwGpjPq1SNO43lGmiRq9HksRim-0jo~-JySMTNQHV4hQ0YYmiQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Diffuse_methane_emissions_abatement_by_organic_and_inorganic_packed_biofilters_Assessment_of_operational_and_environmental_indicators","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago Cuervo","url":"https://independent.academia.edu/SantiagoCuervo19"},"attachments":[{"id":94302608,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302608/thumbnails/1.jpg","file_name":"j.jclepro.2016.11.18520221115-1-1e0g4d0.pdf","download_url":"https://www.academia.edu/attachments/94302608/download_file?st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&st=MTczMjc0MzIyMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Diffuse_methane_emissions_abatement_by_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302608/j.jclepro.2016.11.18520221115-1-1e0g4d0-libre.pdf?1668542723=\u0026response-content-disposition=attachment%3B+filename%3DDiffuse_methane_emissions_abatement_by_o.pdf\u0026Expires=1732746820\u0026Signature=Lul6HHcKimiIMK90obSob2WoxXuv4iiJdr4rt9ifXcc~NaAlStUzk2TYW6iKxRIT1nqLhdtUlqnYgBwel~TIFAV1L0K-O0o1mHWmTD5R8ARTEF6bFNLVttair6V0cHiSqnxN4R08f30RdBGT0rOsAQw6~~gVcD4a3LLRMZdxc0d6ekFXazmuXvYY158ruzKDYI3kb7V9e5SvpvlMPtbGeuB6Vcx2GYXWUTLUN3xR36QZNJDbe0lzJbkvyHp9MOa-by0NYHNSgLDumipBEX2JcyBMqU8VzNeElpQsWwGpjPq1SNO43lGmiRq9HksRim-0jo~-JySMTNQHV4hQ0YYmiQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":55,"name":"Environmental Engineering","url":"https://www.academia.edu/Documents/in/Environmental_Engineering"},{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":1584,"name":"Cleaner Production","url":"https://www.academia.edu/Documents/in/Cleaner_Production"},{"id":14085,"name":"Waste Management","url":"https://www.academia.edu/Documents/in/Waste_Management"},{"id":96825,"name":"Manufacturing Engineering","url":"https://www.academia.edu/Documents/in/Manufacturing_Engineering"},{"id":337999,"name":"Perlite","url":"https://www.academia.edu/Documents/in/Perlite"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering"},{"id":555091,"name":"Compost","url":"https://www.academia.edu/Documents/in/Compost"},{"id":743608,"name":"Biofilter","url":"https://www.academia.edu/Documents/in/Biofilter"}],"urls":[{"id":26007888,"url":"https://api.elsevier.com/content/article/PII:S0959652616320479?httpAccept=text/plain"}]}, dispatcherData: dispatcherData });

Results indicate interesting links between the performance of the biofilter and the presence of extracellular polysaccharide and protein concentration in the liquid phase, with increasing concentrations detected when the process was not stable.","internal_url":"https://www.academia.edu/90855814/EPS_and_SMP_as_Stability_Indicators_During_the_Biofiltration_of_Diffuse_Methane_Emissions","translated_internal_url":"","created_at":"2022-11-15T11:55:14.372-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[],"slug":"EPS_and_SMP_as_Stability_Indicators_During_the_Biofiltration_of_Diffuse_Methane_Emissions","translated_slug":"","page_count":null,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago Cuervo","url":"https://independent.academia.edu/SantiagoCuervo19"},"attachments":[],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":156347,"name":"Methane","url":"https://www.academia.edu/Documents/in/Methane"},{"id":743608,"name":"Biofilter","url":"https://www.academia.edu/Documents/in/Biofilter"}],"urls":[{"id":26007886,"url":"http://link.springer.com/content/pdf/10.1007/s11270-015-2576-2.pdf"}]}, dispatcherData: dispatcherData });

The operation at ambient temperature implies higher methane content in the liquid anaerobic effluent, which finally causes concentrations around 0.01-2.4% in the off-gas released in the anoxic-aerobic chamber (1.25% average). Mass balances indicate that these emissions account for up to 30-35% of the total methane generated in the anaerobic reactor. A conventional biofilter (BF) operated at an empty bed residence time of 4 min was used to treat these emissions for 70 d. In spite of the fluctuations in the methane inlet concentrations derived from the operation of the wastewater treatment plant (WWTP), it was possible to operate at pseudo-steady-state conditions, achieving average removal efficiencies of 76.5% and maximum elimination capacities of 30.1 g m −3 h −1. Odour removal was quantified as 99.1%. Fluorescence in situ hybridization probes as well as metabolic activity assays demonstrated the suitability of the biomass developed in the WWTP as inoculum to start up the BF due to the presence of methanotrophic bacteria.","publication_date":{"day":null,"month":null,"year":2015,"errors":{}},"publication_name":"Environmental

Among activities included in a long-term initiative to ascertain which are the fascioliasis areas of most concern, studies were performed in a recreational farm, including liver fluke infection in different domestic animal species, classification of the lymnaeid vector and verification of natural transmission of fascioliasis by identification of the intramolluscan trematode larval stages found in naturally infected snails. The high prevalences in the domestic animals appeared related to only one lymnaeid species present. Lymnaeid and trematode classification was verified by means of nuclear ribosomal DNA and mitochondrial DNA marker sequencing. Complete sequences of 18S rRNA gene and rDNA ITS-2 and ITS-1, and a fragment of the mtDNA cox1 gene demonstrate that the Argentinian lymnaeid belongs to the species Lymnaea neotropica. Redial larval stages found in a L. neotropica specimen were ascribed to Fasciola hepatica after analysis of the complete ITS-1 sequence. The finding of L. neotropica is the first of this lymnaeid species not only in Argentina but also in Southern Cone countries. The total absence of nucleotide differences between the sequences of specimens from Argentina and the specimens from the Peruvian type locality at the levels of rDNA 18S, ITS-2 and ITS-1, and the only one mutation at the mtDNA cox1 gene suggest a very recent spread. The ecological characteristics of this lymnaeid, living in small, superficial water collections frequented by livestock, suggest that it may be carried from one place to another by remaining in dried mud stuck to the feet of transported animals. The presence of L. neotropica adds pronounced complexity to the transmission and epidemiology of fascioliasis in Argentina, due to the great difficulties in distinguishing, by traditional malacological methods, between the three similar lymnaeid species of the controversial Galba/Fossaria group present in this country: L. viatrix, Galba truncatula and L. neotropica. It also poses a problem with regard to the use, for lymnaeid vector species discrimination, of several molecular techniques which do not show sufficient accuracy, as those relying on the 18S rRNA gene or parts of it, because both L. neotropica and L. viatrix present identical 18S sequence.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="90855811"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="90855811"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 90855811; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=90855811]").text(description); $(".js-view-count[data-work-id=90855811]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 90855811; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='90855811']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 90855811, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=90855811]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":90855811,"title":"Fascioliasis transmission by Lymnaea neotropica confirmed by nuclear rDNA and mtDNA sequencing in Argentina","translated_title":"","metadata":{"abstract":"Fascioliasis is widespread in livestock in Argentina.

learning (SSL) methods based on Contrastive Predictive Coding (CPC). Our experiments show that with the existing algorithms there is a trade off between categorization and segmentation performance. We investigate the source of this conflict and conclude that the use of context building networks, albeit necessary for superior performance on categorization tasks, harms segmentation performance by causing a temporal shift on the learned representations. Aiming to bridge this gap, we take inspiration from the leading approach on segmentation, which simultaneously models the speech signal at the frame and phoneme level, and incorporate multi-level modelling into Aligned CPC (ACPC), a variation of CPC which exhibits the best performance on categorization tasks. Our multi-level ACPC (mACPC) improves in all categorization metrics and achieves state-of-the-art performance in word segmentation.","publication_name":"ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)","grobid_abstract_attachment_id":94302544},"translated_abstract":null,"internal_url":"https://www.academia.edu/90855738/Contrastive_Prediction_Strategies_for_Unsupervised_Segmentation_and_Categorization_of_Phonemes_and_Words","translated_internal_url":"","created_at":"2022-11-15T11:52:58.045-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":140931819,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":94302544,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302544/thumbnails/1.jpg","file_name":"2110.15909v1.pdf","download_url":"https://www.academia.edu/attachments/94302544/download_file?st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Contrastive_Prediction_Strategies_for_Un.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302544/2110.15909v1-libre.pdf?1668542715=\u0026response-content-disposition=attachment%3B+filename%3DContrastive_Prediction_Strategies_for_Un.pdf\u0026Expires=1732746821\u0026Signature=FknxfCda3rcq0aejE833QvN0COLA6L3XRXHiXgRzW6nMlhbSruxD5UM1euqC2xNcgzayrjsoCHS8aDxRGJHQWY2vG9bSxTMcKYjGu989y0S19qWZXnbcKYEARwfjjsfdqiUkDqJ9T7q5WZyM6C0Yhz9crZwyiGxNnQPi6HotgoR~8rAqbgNLzkNuKQqFL0q9jrBlqQVFYM69sMBLapFt5hPWGA9swiws06LsWl-eRVwFMIkolHvXyuXgi3JgQ8EJW1C8XTnHUZmzi4M0q1CY7WPNzBuY8HuWBzaK7zBPftWGO-N2ocmShnA0AJVRuiJTAXTvH74rIyTcEgIWUtKHBA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Contrastive_Prediction_Strategies_for_Unsupervised_Segmentation_and_Categorization_of_Phonemes_and_Words","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":140931819,"first_name":"Santiago","middle_initials":null,"last_name":"Cuervo","page_name":"SantiagoCuervo19","domain_name":"independent","created_at":"2020-01-05T13:41:16.079-08:00","display_name":"Santiago Cuervo","url":"https://independent.academia.edu/SantiagoCuervo19"},"attachments":[{"id":94302544,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/94302544/thumbnails/1.jpg","file_name":"2110.15909v1.pdf","download_url":"https://www.academia.edu/attachments/94302544/download_file?st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&st=MTczMjc0MzIyMSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Contrastive_Prediction_Strategies_for_Un.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/94302544/2110.15909v1-libre.pdf?1668542715=\u0026response-content-disposition=attachment%3B+filename%3DContrastive_Prediction_Strategies_for_Un.pdf\u0026Expires=1732746821\u0026Signature=FknxfCda3rcq0aejE833QvN0COLA6L3XRXHiXgRzW6nMlhbSruxD5UM1euqC2xNcgzayrjsoCHS8aDxRGJHQWY2vG9bSxTMcKYjGu989y0S19qWZXnbcKYEARwfjjsfdqiUkDqJ9T7q5WZyM6C0Yhz9crZwyiGxNnQPi6HotgoR~8rAqbgNLzkNuKQqFL0q9jrBlqQVFYM69sMBLapFt5hPWGA9swiws06LsWl-eRVwFMIkolHvXyuXgi3JgQ8EJW1C8XTnHUZmzi4M0q1CY7WPNzBuY8HuWBzaK7zBPftWGO-N2ocmShnA0AJVRuiJTAXTvH74rIyTcEgIWUtKHBA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science"},{"id":465,"name":"Artificial Intelligence","url":"https://www.academia.edu/Documents/in/Artificial_Intelligence"},{"id":11984,"name":"Speech Recognition","url":"https://www.academia.edu/Documents/in/Speech_Recognition"},{"id":18573,"name":"Categorization","url":"https://www.academia.edu/Documents/in/Categorization"},{"id":93217,"name":"Segmentation","url":"https://www.academia.edu/Documents/in/Segmentation"},{"id":3193313,"name":"arXiv","url":"https://www.academia.edu/Documents/in/arXiv"}],"urls":[{"id":26007843,"url":"http://xplorestaging.ieee.org/ielx7/9745891/9746004/09746102.pdf?arnumber=9746102"}]}, dispatcherData: dispatcherData });
