    This is the third volume of the Encyclopedia of Neutrosophic Researchers, edited from materials offered by the authors who responded to the editor’s invitation. The authors are listed alphabetically. The introduction contains a short history of neutrosophics, together with links to the main papers and books. Neutrosophic set, neutrosophic logic, neutrosophic probability, neutrosophic statistics, neutrosophic measure, neutrosophic precalculus, neutrosophic calculus and so on are gaining significant attention in solving many real life problems that involve uncertainty, impreciseness, vagueness, incompleteness, inconsistent, and indeterminacy. In the past years the fields of neutrosophics have been extended and applied in various fields, such as: artificial intelligence, data mining, soft computing, decision making in incomplete / indeterminate / inconsistent information systems, image processing, computational modelling, robotics, medical diagnosis, biomedical engineering, investment problems, economic forecasting, social science, humanistic and practical achievements

    Bayesian participatory-based decision analysis : an evolutionary, adaptive formalism for integrated analysis of complex challenges to social-ecological system sustainability

    Includes bibliographical references (pages. 379-400).This dissertation responds to the need for integration between researchers and decision-makers who are dealing with complex social-ecological system sustainability and decision-making challenges. To this end, we propose a new approach, called Bayesian Participatory-based Decision Analysis (BPDA), which makes use of graphical causal maps and Bayesian networks to facilitate integration at the appropriate scales and levels of descriptions. The BPDA approach is not a predictive approach, but rather, caters for a wide range of future scenarios in anticipation of the need to adapt to unforeseeable changes as they occur. We argue that the graphical causal models and Bayesian networks constitute an evolutionary, adaptive formalism for integrating research and decision-making for sustainable development. The approach was implemented in a number of different interdisciplinary case studies that were concerned with social-ecological system scale challenges and problems, culminating in a study where the approach was implemented with decision-makers in Government. This dissertation introduces the BPDA approach, and shows how the approach helps identify critical cross-scale and cross-sector linkages and sensitivities, and addresses critical requirements for understanding system resilience and adaptive capacity

    Categories of hypermagmas, hypergroups, and related hyperstructures

    Full text link
    In order to diagnose the cause of some defects in the category of canonical hypergroups, we investigate several categories of hyperstructures that generalize hypergroups. By allowing hyperoperations with possibly empty products, one obtains categories with desirable features such as completeness and cocompleteness, free functors, regularity, and closed monoidal structures. We show by counterexamples that such constructions cannot be carried out within the category of canonical hypergroups. This suggests that (commutative) unital, reversible hypermagmas -- which we call mosaics -- form a worthwhile generalization of (canonical) hypergroups from the categorical perspective. Notably, mosaics contain pointed simple matroids as a subcategory, and projective geometries as a full subcategory.Comment: 48 pages, 3 figure

    Modeling the spatio-temporal organization and segregation of bacterial chromosomes

    Get PDF
    This work examined the spatio-temporal organization and segregation of bacterial DNA in order to investigate the fundamental processes regulating the inheritance of genetic material and the proliferation of life. For the investigation of the spatio-temporal organization of genetic material in the cell fundamental physical principles were used in this work. The aim was to use concepts of polymer physics to formulate physical models of the complex biological reality. These models were evaluated in computer simulations and compared with experimental data. In the first project of this thesis, the spatial organization of DNA in multipartite bacteria (= bacteria with multiple replicons) was investigated. The results of this work reveal high order of spatial organization even for multipartite bacteria. The organization could be reproduced using a physical model of compacted DNA and geometric constraints on individual genes. Furthermore, it was possible to make accurate predictions for different mutants and to predict interactions between replicons with the developed model. The second project focused on the study of simultaneous replication and segregation of bacterial DNA. Segregation patterns of the ori were analyzed in the model organism Bacillus subtilis. Using Molecular Dynamics simulations, it was shown that entropic segregation of chromosomes is a plausible mechanism for the segregation of genetic material that would also explain the observed variability in the experimental data. The model of entropic segregation of bacterial chromosomes was extended in the third project by the implementation of additional segregation mechanisms, so that a large data set of different trajectories of the ori through the cell could be generated. Thus, machine learning models could be used to classify the different segregation movements. The evaluation of the predictions showed very good results and encourages future classification of experimental data based on the developed models. This work is intended to provide new perspectives on the organization of DNA in the bacterial cell as well as a better understanding of the physical basis of cellular processes

    Anterior dental loading and root morphology in Neanderthals

    Distinguer les incisives et canines des Néanderthaliens de celles des hommes modernes peut représenter un défi dans le cas de dents isolées trouvées dans des collections de musée, ou provenant de contextes stratigraphiques perturbés. De plus, la morphologie de la couronne ne peut être utilisée dans le cas de dents fortement usées. Une étude préliminaire basée sur des échantillons limités et des mesures linéaires (Bailey, 2005) propose que la longueur des racines dentaires à elle seule permet de discriminer taxonomiquement les Néanderthaliens des hommes modernes du Paléolithique supérieur et actuels. Cette thèse teste cette hypothèse pour un échantillon de Néanderthaliens et d'hommes modernes, plus large géographiquement et chronologiquement, en utilisant la micro-tomographie. En plus de l'intérêt taxonomique d'explorer la taille et la forme des racines, nous discutons les implications fonctionnelles de la morphologie racinaire des dents antérieures dans le contexte de l'hypothèse des " dents-utilisées-comme-des-outils ", et des activités para-masticatrices. La première partie a été publiée comme suit : Le Cabec, A., Kupczik, K., Gunz, P., Braga, J., and Hublin, J.J. (2012). Long Anterior Mandibular Tooth Roots in Neanderthals Are Not the Result of their Large Jaws. Journal of Human Evolution, pp. 63, 667-681. DOI: 10.1016/j. jhevol.2012.07.003. Cette partie valide la longueur des racines dentaires en tant qu'outil taxonomique pour distinguer les Néanderthaliens tardifs des hommes modernes du Paléolithique Supérieur et récents. En dépit de l'absence de corrélation entre la taille des racines et la taille de la symphyse mentonnière, les Néanderthaliens ont de grandes racines, pour la taille de leurs mâchoires. Il est alors proposé que les courtes racines des hommes modernes récents résulteraient d'une allométrie négative. La seconde partie a été publiée comme suit : Le Cabec, A., Gunz, P., Kupczik, K., Braga, J. and Hublin, J.J. (2013). Anterior Tooth Root Morphology and Size in Neanderthals: Taxonomic and Functional Implications. Journal of Human Evolution, 64, pp. 169-193. DOI: 10.1016/j. jhevol.2012.08.011. La morphologie racinaire est étudiée à travers un large échantillon d'hominidés fossiles et actuels, couvrant une large période chronologique et une vaste zone géographique. Les plus grandes longueurs racinaires observées chez les Néanderthaliens peuvent avoir résulté de la rétention d'une condition ancestrale. L'attribution taxonomique débattue de certains spécimens est discutée à la lumière de la morphologie racinaire des dents antérieures et montre que la longueur racinaire seule ne devrait pas être considérée comme suffisante pour une diagnose taxonomique. La fréquente présence d'hypercémentose et sa distribution non-homogène autour de l'apex racinaire pour les dents antérieures des Néanderthaliens pourrait refléter le régime de charge exercé sur les dents antérieures, probablement utilisées comme une troisième main.Distinguishing Neanderthal and modern human incisors and canines can be challenging in the case of isolated teeth found in museum collections, or from unclear stratigraphic contexts. In addition, the crown morphology cannot be used in the case of heavily worn teeth. A preliminary study based on limited samples and linear measurements (Bailey, 2005) proposed that root length alone can taxonomically discriminate Neanderthals from Upper Paleolithic and extant modern humans. This thesis investigates whether this remains true for a broader chronological and geographical sample of Neanderthals and modern humans, using micro-computed tomography. In addition to the taxonomic interest of investigating root size and shape, we discuss the functional implications of the anterior root morphology in the context of the 'teeth-as-tools' hypothesis and of para-masticatory activities. The first part was published as: Le Cabec, A., Kupczik, K., Gunz, P., Braga, J., and Hublin, J.J. (2012). Long Anterior Mandibular Tooth Roots in Neanderthals Are Not the Result of their Large Jaws. Journal of Human Evolution, 63, pp. 667-681. DOI: 10.1016/j.jhevol.2012.07.003. This part validates root length as a taxonomical tool to distinguish late Neanderthals from Upper Paleolithic and recent modern humans. Despite the absence of correlation between root size and symphyseal size, Neanderthals have large roots for the size of their jaws. It is hypothesized that the short roots of extant modern humans result from a negative allometry. The second part was published as: Le Cabec, A., Gunz, P., Kupczik, K., Braga, J. and Hublin, J.J. (2013). Anterior Tooth Root Morphology and Size in Neanderthals: Taxonomic and Functional Implications. Journal of Human Evolution, 64, pp. 169-193. DOI: 10.1016/j. jhevol.2012.08.011. Root morphology is explored across a chronologically and geographically large sample of fossil and extant hominids. Longer roots in Neanderthals may have resulted from the retention of an ancestral condition. The debated taxonomic attribution of some specimens is discussed in light of anterior tooth root morphology and shows that root length alone should not be sufficient for taxonomic diagnosis. The frequent presence of hypercementosis and its non-homogeneous distribution around the root apex in Neanderthal anterior teeth could reflect the loading regime exerted on the front teeth, likely used as a third hand

    Neutrosophic SuperHyperAlgebra and New Types of Topologies

    In general, a system S (that may be a company, association, institution, society, country, etc.) is formed by sub-systems Si { or P(S), the powerset of S }, and each sub-system Si is formed by sub-sub-systems Sij { or P(P(S)) = P2(S) } and so on. That’s why the n-th PowerSet of a Set S { defined recursively and denoted by Pn(S) = P(Pn-1(S) } was introduced, to better describes the organization of people, beings, objects etc. in our real world. The n-th PowerSet was used in defining the SuperHyperOperation, SuperHyperAxiom, and their corresponding Neutrosophic SuperHyperOperation, Neutrosophic SuperHyperAxiom in order to build the SuperHyperAlgebra and Neutrosophic SuperHyperAlgebra. In general, in any field of knowledge, one in fact encounters SuperHyperStructures. Also, six new types of topologies have been introduced in the last years (2019-2022), such as: Refined Neutrosophic Topology, Refined Neutrosophic Crisp Topology, NeutroTopology, AntiTopology, SuperHyperTopology, and Neutrosophic SuperHyperTopology
