Remaining Useful Life Estimation in Aircraft Components with Federated Learning
Authors: Llasag Rosero Raúl Homero , Silva Catarina , Ribeiro Bernardete 
Published: March 2024

In this work, we compare distributed collaborative learning techniques for Prognostic and Health Management (PHM) systems, focusing on predictive aircraft maintenance. Aircraft industry components are usually evaluated using remaining useful life (RUL) estimations to describe the amount of time left before system health falls. Such estimates have been commonly achieved with traditional degradation estimation methods. These estimation methods have been widely applied in centralized processing architectures, limiting the scalability of PHM systems.
Concerns about data privacy and transfer of large amount of data have also been limiting the construction of decentralized processing architectures. Nevertheless, with the emergence of collaborative training methods of machine learning models, e.g. Federated Learning (FL), the previous referred concerns have being tackled by privacy-preserving communications while keeping data at the network edges. However, the effectiveness of federated learning algorithms using time-series data for prognostic and health management of aircraft systems has been minimally explored.
In this work, we use feed-forward neural networks on centralized and decentralized scenarios to compare the prediction error minimization of FL algorithms, such as, Federated Average (FedAvg) and Federated Proximal Term (FedProx). Our experiments take into account gradient descendent minimization and averaging weights of neural networks. Using FedAvg, we obtained similar prediction errors to the centralized scenario but presenting uncertain predictions along the aggregation iterations. On the other hand, using FedProx, the prediction error curve progressively decreases along the aggregation iterations if μ takes values ~ 0.01.

A gestação é um intervalo no qual a alimentação necessita de uma matriz nutricional adequada, que se torna essencial para o devido crescimento fetal. Um estado nutricional desequilibrado tem sido correlacionado com adversidades na gestação e parto. No presente, as dietas vegetarianas estão em ascensão, entretanto, podem acarretar em incrementos de deficiências nutricionais e energéticas. Este estudo busca examinar os dados disponíveis na literatura científica e determinar se o regime alimentar vegetariano tem repercussões na gestação. Esta é uma análise descritiva da literatura científica, com investigação bibliográfica em plataformas de pesquisa quais sejam: Pubmed, Scielo, Lilacs, BVS entre outros com estudos publicados entre os anos de 2010 a 2021. Foram utilizados critérios de inclusão os seguintes Descritores: “Dieta Vegetariana na Gravidez”, “Dieta Vegana”, “Macronutrientes e Micronutrientes”, “Deficiência Nutricional” e “Desenvolvimento Fetal”, com busca de artigos disponíveis nas línguas portuguesa, inglesa e em espanhol. Portanto, para garantir que as necessidades da mulher grávida sejam atendidas, a adoção de uma dieta vegetariana deve ser planejada e ajustada às demandas fisiológicas da gestante e ao desenvolvimento fetal adequado. É essencial um aconselhamento pré-natal apropriado. Além disso, a literatura sugere uma relação entre deficiências nutricionais e possíveis complicações na saúde da mãe, embora as evidências científicas sejam inconclusivas.

Influence of soil nutrients on net primary productivity in post-mining forests in the Colombian Pacific
Authors: Mosquera Harley Quinto , Cuesta Hamleth Valois , Abadía David Pérez 
Published: March 2024

ABSTRACT

Tropical forests have the highest rates of net primary productivity (NPP) in terrestrial ecosystems and, therefore, may contribute significantly to the mitigation of global climate change. Although NPP is influenced by soil fertility, and recently, in some regions, mining activity in forest ecosystems has intensified. Little is known about how soils determine the restoration of NPP in forests degraded by mining. We evaluated the influence of soil nutrients on wood NPP of post-mining forests in the biogeographic Chocó region (Colombia), with emphasis on the effects of nitrogen (N) and phosphorus (P) limitations in post-mining forests under successional stages of 12-15 or 30-35 years. For this, permanent plots were established in secondary post-mining forests in Jigualito (Colombian Pacific), the wood NPP (accumulated and current) was evaluated, and it was related to soil properties such as organic matter (OM), acidity, Al, total N, available P, magnesium (Mg), potassium (K), calcium (Ca), and texture. An accumulated wood NPP of 0.72 t ha

was recorded in post-mining forests 12-15 years old. Meanwhile, in post-mining forests of 30-35 years, the accumulated wood NPP was 6.52 t ha

. The current wood NPP was 4.25 t ha

in post-mining forests with 30-35 years of recovery. Accumulated NPP positively correlated with soil OM, total N, Ca, Mg, and effective cation exchange capacity–ECEC in post-mining forests. In post-mining forests, a slow recovery of the wood NPP was denoted in the first years. Soil nutrients determined the wood NPP, and a multiple limitation of nutrients with the succession was observed, which corroborates the need to restore the degraded ecosystem in the region.
Microbial contribution to the carbon flux in the soil: A literature review

Published: March 2024

ABSTRACT
Carbon flows into and out of the soil are important processes that contribute to controlling the global climate. The relationship between soil organisms and the climate is interdependent since the organisms that contribute to carbon and greenhouse gas fluxes are simultaneously affected by climate change and soil management. Temperature, soil moisture, pH, nutrient level, redox potential and organic matter quality are key elements affecting the microorganisms involved in organic carbon flows in the soil. Climate, topography (slope and position in the landscape), soil texture, soil mineralogy and land-use regulate those key elements and, thus, the C fluxes in the pedosphere. Soil microbes can increase carbon influx and storage by promoting plant growth, mycorrhizal establishment, and particle aggregation. Conversely, microorganisms contribute to carbon efflux from the soil via methanogenesis, rhizospheric activity, and organic carbon mineralization. Nevertheless, strategies and management practices could be used to balance out carbon emissions to the atmosphere. For example, carbon influx and storage in the soil can be stimulated by plant growth promoting microorganisms, greater plant diversity via crop rotation and cover crops, cultivating mycotrophic plants, avoiding or reducing the use of fungicides and adopting organic farming, no-tillage crop systems and conservative soil management strategies. Therefore, this review aimed to shed light on how soil microorganisms can contribute to increase C influxes to the soil, and its significance for climate change. Then, we also seek to gather the practical actions proposed in the scientific literature to improve carbon sequestration and storage in the soil. In summary, the review provides a comprehensive basis on soil microorganisms as key to carbon fluxes and helpers to lessen climate change by increasing carbon fixation and storage in agroecosystems via stimulation or application of beneficial microorganisms.

Published: March 2024

ABSTRACT
Theobroma cacao, the source for chocolate fabrication, is a high-value crop that faces challenges such as the impact of climate change, pathogens, and cadmium accumulation. Soil associated with T. cacao has been extensively studied, looking for bio-controllers and microorganisms capable of Cd accumulation. However, there is no information about the microbial structure and interactions occurring in soil associated with cacao wild relatives, which represent a repository for biological diversity and its potential for biotechnological applications. We performed an extracellular DNA metabarcoding on soil samples associated with Theobroma spp. and Herrania sp. plants in two localities of the Biogeographic Chocó. We found microbial high diversity indexes and no correlation with plants or sampling locations. Potential cacao pathogens and bio-controllers and unexpected differences in the physicochemical soil properties from close locations were detected. Cadmium, an important economic factor for the commercialization of cacao products, showed significant differences between locations associated with a particular Theobroma species. We discuss some important relationships with soil physicochemical properties, the urgent need to complete the missing information on the diversity of bacterial, fungal and insect groups, and the potential of comprehensive analyses for decision-making regarding land-use and vocation. Also, we did not find the only T. hylaeum tree after three years, evincing the urgent need for conservation strategies in Colombia’s Chocó region.

AbstractQuestionnaires are ever present in survey research. In this study, we examined whether an indirect indicator of general cognitive ability could be developed based on response patterns in questionnaires. We drew on two established phenomena characterizing connections between cognitive ability and people’s performance on basic cognitive tasks, and examined whether they apply to questionnaires responses. (1) The worst performance rule (WPR) states that people’s worst performance on multiple sequential tasks is more indicative of their cognitive ability than their average or best performance. (2) The task complexity hypothesis (TCH) suggests that relationships between cognitive ability and performance increase with task complexity. We conceptualized items of a questionnaire as a series of cognitively demanding tasks. A graded response model was used to estimate respondents’ performance for each item based on the difference between the observed and model-predicted response (“response error” scores). Analyzing data from 102 items (21 questionnaires) collected from a large-scale nationally representative sample of people aged 50+ years, we found robust associations of cognitive ability with a person’s largest but not with their smallest response error scores (supporting the WPR), and stronger associations of cognitive ability with response errors for more complex than for less complex questions (supporting the TCH). Results replicated across two independent samples and six assessment waves. A latent variable of response errors estimated for the most complex items correlated .50 with a latent cognitive ability factor, suggesting that response patterns can be utilized to extract a rough indicator of general cognitive ability in survey research.

Le facteur émotionnel de l’activité : analyser les « angles morts » pour améliorer la QVCT. Bilan d’une recherche immersive en Police Judiciaire française
Authors: Monier Hélène 
Published: March 2024

Cette recherche, s’inscrivant dans un projet scientifique élaboré en partenariat entre notre Centre de Recherche et le CR ENSP 1 , vise à évaluer les risques émotionnels inhérents aux métiers de la police, et les processus de (dys)régulations des émotions mis en place par les policiers/ières et les collectifs policiers, dans un objectif de Qualité de Vie et Conditions de Travail (QVCT). De nombreuses études abordent la question des émotions dans les organisations ces dernières décennies. Mais la composante émotionnelle au travail, dans les pratiques ayant trait à la Gestion des Ressources Humaines (GRH) et au management publics, est un sujet assez récent au sein de milieux professionnels « extrêmes », à haute fiabilité, comme celui de la Police Nationale. Une étude ethnographique et qualitative a été menée par l’auteure au sein de la Direction Territoriale de la Police Judiciaire (DTPJ) d’une métropole française, au cours du printemps 2021. Plusieurs brigades ont été observées : police technique et scientifique, investigation opérationnelle du numérique, division financière, division criminelle, répression du banditisme, office anti-stupéfiants, groupe anti-terroriste. Cette recherche, fondée sur l’immersion de la chercheuse dans des services policiers pendant 26,5 jours et nuits de mai à juin 2021, ainsi que sur 20 entretiens individuels et collectifs, analyse : les émotions vécues par les policiers, leurs pratiques de (dys)régulations émotionnelles aux niveaux individuel, collectif et organisationnel, et révèle leur rapport au sens au travail. Cette recherche fait apparaître l’importance de deux émotions-clefs constituant des « angles morts » du travail : l’intérêt et la frustration, conduisant les policiers à fournir un travail « invisible », et non discuté, sur les affects relatifs à l’activité dans son ensemble. Cette recherche interdisciplinaire mobilise auteure et praticiens autour d’un double objectif : la prévention des risques psychosociaux (RPS), et la QVCT.
Un cas de confiance

La confiance, pierre angulaire mais aussi pierre d’achoppement de l’accompagnement soignant, se révèle peut-être bien également sa pierre philosophale. Confier son corps et/ou son esprit à l’autre pour qu’il en prenne soin, se fier à l’autre pour le soigner au plus près de sa volonté : la réciprocité de la relation de confiance rend, par nature, le rapport soignant-soigné très personnel et mystérieux, quel que soit son degré d’intimité.
Une étrange croyance : la confiance

Published: March 2024

Devant la porte fermée d’une personne malade dont le bénévole ignore tout et qui ignore elle-même son existence, en faut-il de la conviction intime, de la confiance plus qu’en soi-même, en l’autre, pour oser frapper, entrer, se présenter ! Et ceci dans les circonstances particulièrement difficiles de vulnérabilité et d’angoisse – de la maladie grave, de la solitude, de la proximité de la mort.
« Faire le boulot de l’État ». Pratiques de décasage et vigilance citoyenne à Mayotte
Authors: Lehuger Clémentine 
Published: March 2024

À Mayotte en 2016, des groupes de villageois·e·s se livrent durant plusieurs semaines à l’expulsion de centaines de personnes d’origine comorienne. Le Collectif de défense des intérêts de Mayotte (Codim) justifie ces décasages en les présentant comme une réaction à l’inefficacité des services de l’État en matière de contrôle de l’immigration, nécessitant, selon ses termes « de faire le boulot de l’État ». À rebours des approches qui décrivent ces décasages comme des actions violentes en dehors de tout contrôle étatique, cet article montre que ces pratiques vigilantes entretiennent des liens étroits avec l’État dans ce territoire caractérisé par un champ du pouvoir ultra-concurrentiel.
