Distributed IMU Sensors for In-Field Dynamic Measurements on an Alpine Ski
Authors: Beuken Leopold G. , Priest Joshua L. , Hainsworth Travis , Humbert J. Sean
Published: March 2024

Modern ski design is an inherently time-consuming process that involves an iterative feedback loop comprised of design, manufacturing and in-field qualitative evaluations. Additionally consumers can only rely on qualitative evaluation for selecting the ideal ski, and due to the variation in skier styles and ability levels, consumers can find it to be an inconsistent and expensive experience. We propose supplementing the design and evaluation process with data from in-field prototype testing, using a modular sensor array that can be ported to nearly any ski. This paper discusses a new distributed Inertial Measurement Unit (IMU) suite, including details regarding the design and operation, sensor validation experiments, and outdoor in-field testing results. Data are collected from a set of spatially distributed IMUs located on the upper surface of the ski. We demonstrate that this system and associated post-processing algorithms provide accurate data at a high rate (>700 Hz), enabling the measurement of both structural and rigid ski characteristics, and are robust to repetitive testing in outdoor winter conditions.

Published: March 2024

Complex systems science (CSS) and community-based research (CBR) have emerged over the past 50 years as complementary disciplines. However, there is a gap in understanding what has driven the recent proliferation of integrating these two disciplines to study complex and relevant issues. In this review, we report on the results of a scoping review of articles that utilized both disciplines. After two levels of reviewing articles using DistillerSR, a web-based platform designed to streamline and facilitate the process of conducting systematic reviews, we used two forms of natural language processing to extract data. We developed a novel named entity recognition model to extract descriptive information from the corpus of articles. We also conducted dynamic topic modeling to deductively examine in tandem the development of CSS and CBR and to inductively discover the specific topics that may be driving their use in research and practice. We find that among the CSS and CBR papers, CBR topic frequency has grown at a faster pace than CSS, with CBR using CSS concepts and techniques more often. Four topics that may be driving this trend are collaboration within social systems, business management, food and land use and knowledge, and water shed management. We conclude by discussing the implications of this work for researchers and practitioners who are interested in studying and solving complex social, economic, and health-related issues.

Published: March 2024

Cognitive fatigue, a state of reduced mental capacity arising from prolonged cognitive activity, poses significant challenges in various domains, from road safety to workplace productivity. Accurately detecting and mitigating cognitive fatigue is crucial for ensuring optimal performance and minimizing potential risks. This paper presents a comprehensive survey of the current landscape in cognitive fatigue detection. We systematically review various approaches, encompassing physiological, behavioral, and performance-based measures, for robust and objective fatigue detection. The paper further analyzes different challenges, including the lack of standardized ground truth and the need for context-aware fatigue assessment. This survey aims to serve as a valuable resource for researchers and practitioners seeking to understand and address the multifaceted challenge of cognitive fatigue detection.

Aegerolysins are a family of proteins that recognize and bind to specific membrane lipids or lipid domains; hence they can be used as membrane lipid sensors. Although aegerolysins are distributed throughout the tree of life, the most studied are those produced by the fungal genus Pleurotus. Most of the aegerolysin-producing mushrooms code also for proteins containing the membrane attack complex/perforin (MACPF)-domain. The combinations of lipid-sensing aegerolysins and MACPF protein partners are lytic for cells harboring the aegerolysin membrane lipid receptor and can be used as ecologically friendly bioinsecticides. In this work, we have recombinantly expressed four novel aegerolysin/MACPF protein pairs from the mushrooms Heterobasidion irregulare, Trametes versicolor, Mucidula mucida, and Lepista nuda, and compared these proteins with the already studied aegerolysin/MACPF protein pair ostreolysin A6–pleurotolysin B from P. ostreatus. We show here that most of these new mushroom proteins can form active aegerolysin/MACPF cytolytic complexes upon aegerolysin binding to membrane sphingolipids. We further disclose that these mushroom aegerolysins bind also to selected glycerophospholipids, in particular to phosphatidic acid and cardiolipin; however, these interactions with glycerophospholipids do not lead to pore formation. Our results indicate that selected mushroom aegerolysins show potential as new molecular biosensors for labelling phosphatidic acid.

Biliary atresia (BA) is a poorly understood and devastating obstructive bile duct disease of newborns. Biliatresone, a plant toxin, causes BA-like syndrome in some animals, but its relevance in humans is unknown. To validate the hypothesis that biliatresone exposure is a plausible BA disease mechanism in humans, we treated normal human liver organoids with biliatresone and addressed its adverse effects on organoid development, functions and cellular organization. The control organoids (without biliatresone) were well expanded and much bigger than biliatresone-treated organoids. Expression of the cholangiocyte marker CK19 was reduced, while the hepatocyte marker HFN4A was significantly elevated in biliatresone-treated organoids. ZO-1 (a tight junction marker) immunoreactivity was localized at the apical intercellular junctions in control organoids, while it was markedly reduced in biliatresone-treated organoids. Cytoskeleton F-actin was localized at the apical surface of the control organoids, but it was ectopically expressed at the apical and basal sides in biliatresone-treated organoids. Cholangiocytes of control organoids possess primary cilia and elicit cilia mechanosensory function. The number of ciliated cholangiocytes was reduced, and cilia mechanosensory function was hampered in biliatresone-treated organoids. In conclusion, biliatresone induces morphological and developmental changes in human liver organoids resembling those of our previously reported BA organoids, suggesting that environmental toxins could contribute to BA pathogenesis.

COVID-19 vaccines have been shown to be effective in preventing severe illness, including among pregnant persons. The vaccines appear to be safe in pregnancy, supporting a continuously favorable overall risk/benefit profile, though supportive data for the U.S. over different periods of variant predominance are lacking. We sought to analyze the association of adverse pregnancy outcomes with COVID-19 vaccinations in the pre-Delta, Delta, and Omicron SARS-CoV-2 variants’ dominant periods (constituting 50% or more of each pregnancy) for pregnant persons in a large, nationally sampled electronic health record repository in the U.S. Our overall analysis included 311,057 pregnant persons from December 2020 to October 2023 at a time when there were approximately 3.6 million births per year. We compared rates of preterm births and stillbirths among pregnant persons who were vaccinated before or during pregnancy to persons vaccinated after pregnancy or those who were not vaccinated. We performed a multivariable Poisson regression with generalized estimated equations to address data site heterogeneity for preterm births and unadjusted exact models for stillbirths, stratified by the dominant variant period. We found lower rates of preterm birth in the majority of modeled periods (adjusted incidence rate ratio [aIRR] range: 0.42 to 0.85; p-value range: <0.001 to 0.06) and lower rates of stillbirth (IRR range: 0.53 to 1.82; p-value range: <0.001 to 0.976) in most periods among those who were vaccinated before or during pregnancy compared to those who were vaccinated after pregnancy or not vaccinated. We largely found no adverse associations between COVID-19 vaccination and preterm birth or stillbirth; these findings reinforce the safety of COVID-19 vaccination during pregnancy and bolster confidence for pregnant persons, providers, and policymakers in the importance of COVID-19 vaccination for this group despite the end of the public health emergency.

Published: March 2024

Scottish Vision Group has become a yearly event for vision scientists based in Scotland since its inception in 2001. Each year, the conference is hosted at a different location and organised by a different team. The 2023 SVG meeting was hosted in the city of Dundee by Abertay University. Delegates travelled from the United Kingdom, Europe and beyond. The meeting started with a roundtable panel discussion sponsored by Meta Reality Labs. The roundtable, titled The Past, Present and Future of Visual Search, was organised and presented by Árni Kristjánsson (Iceland), Ioan Smart (Abertay) and Ian Thornton (Malta). The MDPI Keynote lecture was introduced by Professor Andrew Parker (Oxford University and Otto-von-Guericke University in Magdeburg, Germany) and presented by Prof. Timothy Ledgeway (Nottingham) on sensory eye dominance and plasticity in adult binocular vision. The remaining two days of the conference hosted a wide range of talks on topics ranging from insect navigation to visual illusions, facial recognition and binocular coding. The Saturday evening saw a special event where delegates explored the sensory properties of a range of single-malt whiskies. Here, we present a selection of abstracts for the various talks and posters.
Analysis of Potential Water Inflow Rates at an Underground Coal Mine Using a WOA-CNN-SVM Approach
Authors: Liu Weitao , Ren Yuying , Meng Xiangxi , Tian Bo , Lv Xianghai
Published: March 2024

The water yield of aquifers increases the risk of water inflow, threatens the safe production of coal mines, and even causes geological disasters and construction hazards. To predict water yield quickly and accurately, multiple composite factors are used to invert unit water inflow rates to judge water yield grade. Taking the typical representative of north China-type coal fields as an example, six factors are selected: aquifer thickness, the radius of influence, normalized drawdown, permeability coefficient, the core rate of drilling holes, and the proportion of clay thickness to the thickness of the lower group. The whale optimization algorithm (WOA)–convolutional neural network (CNN)–support vector machine (SVM) model is established with the unit water inflow rate as the forecast target, and different models are selected for comparison. The water yield zoning map is obtained by bringing the borehole data into the model for prediction. The findings indicate that the root mean square error and average absolute error of the composite predictive model models are 0.0318 and 0.0268, respectively, and the model outperforms alternative models. The predicted water yield zoning aligns well with the actual conditions, offering a novel paradigm for water yield assessment.

Research and Optimization of Four Serpentine-Wave Flow Fields in PEMFC
Authors: Yan Fayi , Lu He , Yao Jian , Pei Xuejian , Fan Xiang
Published: March 2024

The layout of the cathode flow field largely determines the net output power of the proton exchange membrane fuel cell (PEMFC). To make the normal mass transfer effect best, the longitudinal channel was waved based on four serpentine flow channels, and the effects of sag depth and longitudinal channel width on the output efficiency of the cell were explored. The results show that the wave channel design systematically enhances the forced convection between adjacent channels, which can prevent a large zone of oxygen starvation zone at the outlet of the channel. The increase of the normal velocity in the gas transmission process will inevitably induce a significant enhancement of the mass transfer effect and obtain a higher current density in the reaction zone. For the longitudinal channel width, it is found that increasing its size in the effective range can greatly reduce the channel pressure drop without reducing the output power, thereby improving the overall efficiency. When the sag depth and longitudinal channel width gradient are 0.6 mm and 0.2 mm respectively, PEMFC can obtain the best comprehensive performance.

Aux confins de l’Asie et de la Galatie à l’époque impériale romaine, entre Apamée de Phrygie et Apollonie de Pisidie : routes et territoires de cités, fiscalité et sécurité
Authors: Christol Michel
Published: March 2024

The boundary erected by the city of Apollonia at the frontier of Galatia and Asia was intended to show the distribution of fiscal burdens, in charge of cities. It concerned the transport system for a main road and public supplies. The inscription, from the Hadrianic period, is linked to the transformation of the route in via militaris of the Roman empire, across Asia minor, between Ephesos and the Cilician Gates.
De l’océan au phare d’Alexandrie : la conque de Triton
Authors: Boulinguez Corinne
Published: March 2024

L’image du phare d’Alexandrie pourvu de quatre tritons aux angles de son premier étage est tout à fait caractéristique des représentations figurées à partir du Ier s. ap. J.-C. Ces tritons accompagnés de leur conque sont une spécificité alexandrine, puisqu’on ne les retrouve sur aucun autre phare du monde antique. Ce travail réunit une riche documentation textuelle, iconographique et conchyliologique de(s) Triton(s). La conque, instrument sonore marin, devient l’attribut principal de cette divinité en lien avec la navigation. C’est dans un contexte prolifique que les ingénieurs alexandrins choisissent d’automatiser ces divinités bienfaitrices du monde maritime, afin de créer une véritable signalétique portuaire.
La política africana de Calígula y los primeros legados imperiales. de la legio III Augusta: Una revision
Authors: Olmo López Rubén
Published: March 2024

L’article présente une révision de la politique africaine de Caligula à propos de l’annexion de la Maurétanie. L’auteur soutient la cohérence des décisions de l’empereur et il propose que la mesure de transférer le commandement de la IIIe Légion Auguste à un légat impérial ne visait pas à limiter le pouvoir du proconsul d’Afrique mais faisait partie de la stratégie d’annexion de la Maurétanie. Il propose aussi l’hypothèse que C. Suetonius Paulinus et Cn. Hosidius Geta ne furent pas gouverneurs de la Maurétanie pendant la guerre, mais les premiers légats impériaux de la legio III sous Claude.
Zénobie et la justice du fleuve (Tacite, Annales, XII, 51).
Authors: Meulder Marcel
Published: March 2024

Tacite (Annales, XII, 51), en qualifiant une partie du cours de l’Araxe de placidus semble doter ce fleuve d’Arménie d’un rôle de dieu justicier : celui-ci sauve de la mort Zénobie, fille du roi d’Arménie et épouse abandonnée du perfide Radamiste, ennemi de Rome. Qui plus est, elle est recueillie et honorée par le Parthe Tiridate qui deviendra l’ «allié » de Rome sous Néron. L’historien fait écho ailleurs (VI, 37, et XV, 7-8) au concept indo-européen de la «justice » du fleuve (en l’occurrence de l’Euphrate) pour dénoncer la transgression que commettent certains généraux romains ou rois protégés par Rome, en voulant lier davantage l’Arménie à Rome. Mais le fleuve ne châtie plus (immédiatement) le transgresseur.

Deux manières d’invoquer les dieux. Emplois de νή et de μά en grec classique
Authors: Denizot Camille
Published: March 2024

Cette étude porte sur les expressions qui permettent d’invoquer les dieux et qui font intervenir les particules νή et μά, toutes deux accompagnées de l’accusatif du nom du dieu (le type νὴ/ μὰ (τὸν) Δία). Pour quelles raisons existet-il deux particules distinctes pour une expression à première vue équivalente ? On considère traditionnellement que νή et μά sont des particules de serment, à valeur affirmative pour νή et à valeur négative pour μά. Les contre-exemples abondent, cependant, et les dictionnaires se font l’écho de cette difficulté. L’article repose sur l’étude d’un vaste corpus de près de 1000 occurrences à l’époque classique et permet de nuancer et de préciser la conception traditionnelle. On établit tout d’abord que νή et μά ne sont pas en elles-mêmes des particules de serment : il s’agit de particules qui permettent d’invoquer les dieux, y compris dans des contextes qui ne relèvent pas du serment, pour de simples exclamations. De plus, l’existence de deux particules distinctes est certes liée à l’opposition entre négation et affirmation, mais il est nécessaire de prendre en compte le niveau des présupposés : alors que νή permet de renchérir sur un présupposé positif, μά permet de renchérir sur un présupposé négatif. Ces deux particules expriment donc un positionnement par rapport à l’interlocuteur.
Les jeux dans l’Onomasticon I 30 ; VI 107, 109 ; VII 203- 205 ; IX 94-129 de Pollux
Authors: Costanza Salvatore
Published: March 2024

Julius Pollux, orateur et lexicographe du IIe siècle ap. J. C., né à Naucratis, colonie grecque de l’Égypte, est connu comme l’auteur d’un dictionnaire du grec classique, l’Onomasticon, où il adopte un classement par matière. Ce dictionnaire en 10 livres est une source majeure pour l’histoire des jeux grécoromains, qu’il décrit à plusieurs reprises, dans une section du livre IX (94-129) et aussi dans le livre VI dédié au symposium pour les jeux du banquet grec (énigmes et cottabe) et dans le livre VII pour les jeux de hasard (dés, pions). En définitive, le dictionnaire de Pollux répond au souci de transmettre à tous les membres de l’élite intellectuelle de l’empire, l’euglôttia, le bon choix des mots en vue de la maîtrise de la langue attique, mais au même temps il permet de connaître des détails de la culture ludique ancienne autrement perdus à jamais tels que l’ergonomie des jeux, l’âge et le sexe des participants, parfois même les comptines récitées par les enfants.

Suétone, Sur les jeux des Grecs
Authors: Costanza Salvatore
Published: March 2024

Caius Tranquillus Suétone (env. 70-122), historien réputé pour les Vies des Césars et érudit aux multiples intérêts, a aussi écrit une monographie sur les jeux gréco-romains, dont ne survivent que de très courts extraits conservés dans des citations tardives. Cette oeuvre était spécifiquement centrée sur la culture ludique, tandis qu’une autre source majeure telle que l’Onomasticon de Julius Pollux, orateur et lexicographe de la IIe moitié du IIe siècle ap. J. C., aborde ce sujet en marge d’une collection des Realien de l’Antiquité. Ce dictionnaire du grec classique organisé par matières expose les noms des jeux en des passages isolés dans l’architecture de ses dix livres. Le recueil des extraits de Suétone est une mine inépuisable à l’égard des jeux antiques qu’il décrit en détail ; l’auteur permet de découvrir la vie quotidienne et ses représentations idéologiques à travers des jeux du banquet tels que le cottabe ; des énigmes et devinettes ; des jeux de plateau avec dés et pions et d’autres passe-temps. En définitive, Suétone offre la mise à jour de la lexicographie au sujet de l’homo ludens, son but est comparable au souci de Pollux de transmettre le bon choix des mots (euglôttia), afin de maîtriser la langue attique. En même temps, l’érudit romain permet de récupérer des aspects de la culture ludique ancienne tels que l’ergonomie et les règles des jeux, le profil des participants, parfois même les comptines récitées par les enfants.
Pre-discharge heart failure with reduced ejection fraction In elderly patients after myocardial infarction
Authors: Nguyen Thanh Huan , Phan Thanh Hai Nam , Vu Hoang Vu , Nguyen Van Tan
Published: March 2024

Background: The prognosis of elderly people with myocardial infarction has improved over the past decade thanks to advances in treatment, but the rate of heart failure due to coronary heart disease continues to increase. Currently, little is known about heart failure with reduced ejection fraction (HFrEF) before discharge in older adults with myocardial infarction.

Objective: To determine the rate of pre-discharge heart failure with reduced ejection fraction in elderly patients after myocardial infarction and related factors.

Methods: Cross-sectional study involving older patients with myocardial infarction from September 2022 to March 2023 in the Interventional Cardiology Department, Thong Nhat Hospital and the Interventional Cardiology Department, University Medical Center at Ho Chi Minh city.

Results: Of 326 ≥ 60 years old patients presented with myocardial infarction, 100 patients (30.7%) had HFrEF before discharge. Compared with the non-HFrEF group, the pre-discharge HFrEF was older and more frail, had a lower rate of coronary angiography and coronary intervention. There was no difference in the BCIS-JS scores between 2 groups, although the pre-discharge BCIS-JS ratio was lower in the HFrEF group.

Conclusion: In elderly patients with myocardial nfarction, our study found that the rate of pre-discharge HFrEF was 30.7%. The HFrEF group had a higher number of frail patients, more likely to be medically treated alone, and there was no difference in BCIS-JS scores.

Key words: elderly patients; frailty; myocardial infarction; heart failure after myocardial infarction; heart failure reduced ejection fraction.
Characteristics and correlation between FFR and RFR of non-culprit lesions in acute myocardial infarction
Authors: Chau Do Truong Son , Hoang Anh Tien , Truong Quang Binh , Nguyen Do Anh , Nguyen Dinh Dat , Le Manh Thong
Published: March 2024

Background: While resting-full cycle ratio (RFR) is strongly correlated with fractional flow reserve (FFR), it has been extensively examined in stable coronary artery disease. However, there is a lack of evaluation regarding non-culprit lesions in patients with acute myocardial infarction (AMI).

Objectives: To investigate the clinical characteristics and to identify the correlation and discordance between FFR and RFR among AMI patients with non-culprit lesions. Methods: A retrospective cohort study was conducted in 44 AMI patients who underwent percutaneous coronary intervention (PCI) for culprit lesions and > 90% stenosis non-culprit lesions. With non-culprit stenosis from 50 - 90%, 23 patients had simultaneous measurements of both FFR and RFR, and 17 patients underwent PCI based on FFR ≤ 0.8.

Results: Approximately 79.5% of patients exhibited a presence of two or more risk factors associated with coronary artery disease. In 44 culprit lesions, 40.9% of cases located in the RCA branch, while in 46 nonculprit lesions, 61.4% of cases were found in the LAD branch. The average FFR among 44 patients was 0.82 ± 0.13. There was a significant improvement in FFR after PCI (0.89 ± 0.07) compared to pre-PCI (0.70 ± 0.11) in 17 patients with p < 0.001. The mean RFR among the 23 patients was 0.84 ± 0.12. Among 12 patients with positive RFR, RFR after PCI (0.95 ± 0.04) was higher than pre-PCI (0.78 ± 0.13) with p = 0.002. Furthermore, pre-PCI RFR showed a strong positive correlation with FFR (r = 0.662, p = 0.001). The discordant rate between RFR and FFR was 26.8%. The discordant rate of FFR and RFR measurements was 26.1%. Additionally, the left anterior descending artery (LAD) was assumed as a predictor of discordance in the high FFR group (FFR > 0.80) and low RFR group (RFR ≤ 0.89).

Conclusion: The low discordance rate and strong correlation between FFR and RFR suggest their complementary roles in the assessment of intermediate non-culprit lesions in patients with AMI.

Key words: fractional flow reserve, resting full-cycle ratio, non-culprit lesion, correlation, acute myocardial infarction.

Published: March 2024

Neste artigo, estudamos a dinâmica de um pêndulo matemático planar com um bulbo eletricamente carregado. Próximo ao pêndulo, há um fio horizontal infinito, também carregado e oscilando harmonicamente na direção vertical. O problema apresenta duas posições na vertical que são equilíbrios independentemente dos parâmetros envolvidos. Utilizando o Teorema de Krein-Gelfand-Lidskii e o Método de Deprit-Hori, analisamos a estabilidade paramétrica desses equilíbrios, sendo construídas superfícies de fronteira que separam regiões de instabilidade e estabilidade no espaço de parâmetros.

Este artigo traz os e-books interativos como uma possibilidade para articular e organizar diferentes recursos tecnológicos para fins pedagógicos, com as percepções de licenciandos em Matemática sobre essa proposição, no contexto da formação de professores, sobre a temática das distintas concepções de variável no ensino de Álgebra. Por meio de uma aula remota apresentamos o e-book aos discentes e solicitamos que estes, posteriormente, interagissem e realizassem uma leitura na íntegra do material. Para coleta de dados, elaboramos um questionário que visou o levantamento das limitações e potencialidades do recurso no que tange seu uso, organização e compreensão do conteúdo. Pelo seu caráter descritivo, a pesquisa segue uma perspectiva qualitativa. Em nossas análises, confirmamos como principal potencialidade do e-book para fins pedagógicos a capacidade de agregar no mesmo material, diversas mídias e recursos, sendo que as limitações apontadas foram a necessidade de conexão à internet e a de algum dispositivo tecnológico para acessá-lo. Constatamos que os licenciandos estão abertos à possibilidade de uso de tecnologias digitais como as apresentadas no formato de um e-book interativo em suas futuras práticas docentes, e que os recursos utilizados foram coerentes e suficientes para mediar a discussão sobre as concepções de Álgebra no ensino de Matemática.

Encontrar a solução exata para um modelo matemático pode se tornar uma tarefa difícil,ou até mesmo impossível. Desta forma, é imprescindível que técnicas para aproximaçãode soluções sejam estudadas e empregadas toda vez que não seja possível obter soluçõesexatas. Neste artigo será considerada a teoria das perturbações para obter a solução deuma equação diferencial com perturbação singular, onde será mostrado que a abordagempadrão não fornece resultados satisfatórios. E portanto, uma nova abordagem se faznecessária, neste caso será empregado o chamado método das expansões emparelhadas.

Die Grundschulwerkstatt an der Universität Bremen. Entwicklungen zwischen Autonomie und Partizipation
Authors: Groß Selina , Trostmann Sven , Baar Robert
Published: March 2024

Partizipation und Autonomie sind wesentliche Paradigmen der Arbeit in und von Hochschullernwerkstätten. Sie stehen dabei in einem Spannungsverhältnis, das nicht immer leicht zu moderieren ist. Der vorliegende Beitrag geht mit Blick auf die Grundschulwerkstatt an der Universität Bremen der Frage nach, inwieweit Autonomie und Partizipation in den dort stattfindenden Programmen und Interaktionen ineinandergreifen, parallel stattfinden oder nebeneinander existieren, ohne dass Partizipation das autonome Handeln des Individuums beeinträchtigt bzw. Autonomie partizipativen Strukturen entgegensteht. Der historische Rückblick auf die Entwicklung der Grundschulwerkstatt zeigt, dass die Institution ‚Universität‘ erheblichen Einfluss auf das Verhältnis von Autonomie und Partizipation genommen hat und noch immer nimmt. Mit gezielten Maßnahmen, wie bspw. die Einführung eines im Beitrag beschriebenen konsensorientierten Entscheidungsverfahrens, gelingt es der Grundschulwerkstatt dennoch, beide Prinzipien als konstituierende Elemente in die Hochschullernwerkstättenpraxis zu integrieren und im Konstrukt einer kollektiv-partizipativen Autonomie zu vereinen.
