We investigate several fluctuation effects in high-energy hadronic and nuclear collisions through the analysis of different observables. To introduce fluctuations in the initial stage of collisions, we use the interacting gluon model (IGM) modified by the inclusion of the impact parameter. The inelasticity and leading-particle distributions follow directly from this model. The fluctuation effects on rapidity distributions are then studied using Landau's hydrodynamic model in one dimension. To investigage further the effects of the multiplicity fluctuation, we use the longitudinal phase-space (...) model, with the multiplicity distribution calculated within the hydrodynamic model, and the initial conditions given by the IGM. Forward-backward correlation is obtained in this way. (shrink)

In this paper we give a brief treatment of a theory of proofs for a system of Full Intuitionistic Linear Logic. This system is distinct from Classical Linear Logic, but unlike the standard Intuitionistic Linear Logic of Girard and Lafont includes the multiplicative disjunction par. This connective does have an entirely natural interpretation in a variety of categorical models of Intuitionistic Linear Logic. The main proof-theoretic problem arises from the observation of Schellinx that cut elimination fails outright for an intuitive (...) formulation of Full Intuitionistic Linear Logic; the nub of the problem is the interaction between par and linear implication. We present here a term assignment system which gives an interpretation of proofs as some kind of non-deterministic function. In this way we find a system which does enjoy cut elimination. The system is a direct result of an analysis of the categorical semantics, though we make an effort to present the system as if it were purely a proof-theoretic construction. (shrink)

We introduce Pura Vida Neutrosophic Algebra, an algebraic structure consisting of neutrosophic numbers equipped with two binary operations namely addition and multiplication. The addition can be calculated sometimes with the function min and other times with the max function. The multiplication operation is the usual sum between numbers. Pura Vida Neutrosophic Algebra is an extension of both Tropical Algebra (also known as Min-Plus, or Min-Algebra) and Max-Plus Algebra (also known as Max-algebra). Tropical and Max-Plus algebras are algebraic structures included in (...) semirings and their operations can be used in matrices and vectors. Pura Vida Neutrosophic Algebra is included in Neutrosophic semirings and can be used in Neutrosophic matrices and vectors. (shrink)

Este trabalho propõe analisar a presença da religião em alguns espaços públicos educacionais. Por meio da metodologia da observação participante identificamos dois momentos que se articulam entre si: a influência da Escola sem Partido ao longo dos estágios docentes do curso de Ciências Sociais Licenciatura em Campos dos Goytacazes; e a presença de movimentos missionário cristãos, originários dos EUA, que visam influenciar a juventude estudantil evangélica a uma transformação social, nacional e mundial, no espaço universitário. Tais descrições nos traz questionamentos (...) sobre os desafios e perspectivas da formação docente nos voltando, novamente, para a discussão entre ciência, religião e política. Sendo assim, o presente trabalho nos traz muitas interrogações sobre algumas questões que perpassam a questão religiosa e são pertinentes ao debate educacional. Diante da organização e expressões de fé demarcados por discursos e ações de estudantes visamos trazer breves reflexões sobre o ensino de Sociologia no cotidiano escolar e despertar atenção para a presença de movimentos religiosos no espaço universitário.

In an unpublished note Reddy introduced an extended intuitionistic linear calculus, called LLMS (for Linear Logic Model of State), to model state manipulation via the notions of sequential composition and ‘regenerative values’. His calculus introduces the connective ‘before’ ▹ and an associated modality †, for the storage of objects sequentially reusable. Earlier and independently de Paiva introduced a (collection of) dialectica categorical models for (classical and intuitionistic) Linear Logic, the categories Dial2Set. These categories contain, apart from the structure needed (...) to model linear logic, an extra tensor product functor and an extra comonad structure corresponding to a modality related to the extra tensor product. It is surprising that these works arising from completely different motivations can be related in a meaningful way. In this article, following joint work with Corrêa and Haeusler, we first adapt Reddy's system LLMS providing a commutative version of the connective ‘before’ and its associated modality and then construct a dialectica category on Sets , which we show is a sound model for the modified version of Reddy's the system LLMSc. Moreover, following the work of Tucker, we provide another variant of the Dialectica categories with a non-commutative tensor and its associated modality, which models soundlyLLMS itself. We conclude with some speculation on future applications. (shrink)

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4— our formulation has several important metatheoretic properties. In addition, we study models of IS4— not in the framework of Kirpke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models but also (...) a means of modelling proofs as well as provability. (shrink)

Linguistic Issues in Language Technology (LiLT) is an open-access journal that focuses on the relationships between linguistic insights and language technology. In conjunction with machine learning and statistical techniques, deeper and more sophisticated models of language and speech are needed to make significant progress in both existing and newly emerging areas of computational language analysis. The vast quantity of electronically accessible natural language data (text and speech, annotated and unannotated, formal and informal) provides unprecedented opportunities for data-intensive analysis of linguistic (...) phenomena, which can in turn enrich computational methods. Taking an eclectic view on methodology, LiLT provides a forum for this work. In this volume, contributors offer new perspectives on semantic representations for textual inference. (shrink)

How can a work of art give us clues about scientific aspects? How can chemistry help a painter enhance his creativity and, above all, preserve the original characteristics of his work? Does an artist require scientific knowledge to innovate or, at least, not to be faked? Other symbiotic fields between art and science are: tattoos, as body art with physical and chemical consequences; pigments, as basic materials with interesting historiographical preparations; spectroscopy diagnosis, as very broad and thorough method of analysis (...) ; biosensors, as one of the applications of new pigments. Note also the interconnection between the several possible paths of science and art, which reflect new challenges with enormous potential investigated through a literature review and the application as a case study in an educational inquiry module.

O DIREITO À CIDADE NA PERSPECTIVA DO USO DO SOLO E DO EQUIPAMENTO SOCIAL.

By referring to H. Bergson's theory about the evolutionary process, this article reflects on the antinomic character of the two fundamental tendencies of the vital movement, which are pure time and materiality. Starting from the importance of the image in this philosophy, it focuses on the Bergsonian ontology, questioning the notion of vital elan and how matter comes and the real-time is inscribed in it. By highlighting the ambiguity of the role played by materiality in the tensioning of vital forces, (...) the discussion explains that the original impulse establishes its antipode. Thus, it reveals the dramatic character that permeates the movement intrinsic to the history of life, in which effort and struggle are correlated to the limits of the impulse that moves it - and inevitable questions for the creative act that defines it.

Este livro traz uma importante contribuição à compreensão do universo político e social das teorias desenvolvidas do educador Paulo Freire. Nele, o trabalho do educador é analisado como tributário da ideologia nacional desenvolvimentista desdobrada no ISEB dos anos 50 até a publicação da obra de Álvaro Vieira Pinto nos anos 60.

The first aim of this note is to describe an algebraic structure, more primitive than lattices and quantales, which corresponds to the intuitionistic flavour of Linear Logic we prefer. This part of the note is a total trivialisation of ideas from category theory and we play with a toy-structure a not distant cousin of a toy-language. The second goal of the note is to show a generic categorical construction, which builds models for Linear Logic, similar to categorical models GC of (...) [deP1990], but more general. The ultimate aim is to relate different categorical models of linear logic. (shrink)

This thesis describes two classes of Dialectica categories. Chapter one introduces dialectica categories based on Goedel's Dialectica interpretation and shows that they constitute a model of Girard's Intuitionistic Linear Logic. Chapter two shows that, with extra assumptions, we can provide a comonad that interprets Girard's !-course modality. Chapter three presents the second class of Dialectica categories, a simplification suggested by Girard, that models (classical) Linear Logic and chapter four shows how to provide modalities ! and ? for this second class (...) of construction.

Hybrid logics are a principled generalization of both modal logics and description logics, a standard formalism for knowledge representation. In this paper we give the first constructive version of hybrid logic, thereby showing that it is possible to hybridize constructive modal logics. Alternative systems are discussed, but we fix on a reasonable and well-motivated version of intuitionistic hybrid logic and prove essential proof-theoretical results for a natural deduction formulation of it. Our natural deduction system is also extended with additional inference (...) rules corresponding to conditions on the accessibility relations expressed by so-called geometric theories. Thus, we give natural deduction systems in a uniform way for a wide class of constructive hybrid logics. This shows that constructive hybrid logics are a viable enterprise and opens up the way for future applications. (shrink)

A common misconception among logicians is to think that intuitionism is necessarily tied-up with single conclusion calculi. Single conclusion calculi can be used to model intuitionism and they are convenient, but by no means are they necessary. This has been shown by such influential textbook authors as Kleene, Takeuti and Dummett, to cite only three. If single conclusions are not necessary, how do we guarantee that only intuitionistic derivations are allowed? Traditionally one insists on restrictions on particular rules: implication right, (...) negation right and universal quantification right are required to be single conclusion rules. In this note we show that instead of a cardinality restriction such as one-conclusion-only, we can use a notion of dependency between formulae to enforce the constructive character of derivations. The system we obtain, called FIL for full intuitionistic logic, satisfies basic properties such as soundness, completeness and cut elimination. We present two motivating applications of FIL and discuss some future work. (shrink)

The λσ-calculus adds explicit substitutions to the λ-calculus so as to provide a theoretical framework within which the implementation of functional programming languages can be studied. This paper generalises the λσ-calculus to provide a linear calculus of explicit substitutions, called xDILL, which analogously describes the implementation of linear functional programming languages.Our main observation is that there are non-trivial interactions between linearity and explicit substitutions and that xDILL is therefore best understood as a synthesis of its underlying logical structure and the (...) technology of explicit substitutions. This is in contrast to the λσ-calculus where the explicit substitutions are independent of the underlying logical structure. (shrink)

El presente trabajo pretende analiza casos de procesos y dramas sociales vinculados a eventos generados en la vía pública, donde el comportamientos de conductores y peatones está atravesado por reglas y valores que más allá de estar legislada por las leyes y normas de tránsito, se sitúa en los preceptos de una vida moral laica que actúa restituyendo el orden público/vial frente a cualquier acto que lo amenace. En este sentido se apela a conceptos como el de solidaridad, moralidad y (...) anomia. Por último se reflexiona sobre la transgresión a las normas viales. (shrink)

This article discusses work on implementing emotional and cultural models into synthetic graphical characters. An architecture, FAtiMA, implemented first in the antibullying application FearNot! and then extended as FAtiMA-PSI in the cultural-sensitivity application ORIENT, is discussed. We discuss the modelling relationships between culture, social interaction, and cognitive appraisal. Integrating a lower level homeostatically based model is also considered as a means of handling some of the limitations of a purely symbolic approach. Evaluation to date is summarised and future directions discussed.

Within New Testament writings, but in a special way in Paul’s letters, we can observe a significant presence of the greek term parresía, or frank language. This term was not only a rhetorical-linguistic instrument, on Paul’s contemporary time, but an attitude made by the speaker, or by the epistolar author before his recipients. On Eph 6,19, we see this term and its relation with the evangelizing mission of the author. Moreover, this concept was not only a linguistic function for Paul’s (...) writings and time actions, but it can have an effectiveness in present time. (shrink)

Este artigo discute as transformações na indústria fonográfica desde os anos 90 provocadas pelo formato mp3, que, em uma primeira abordagem, é apontado como responsável pelo encolhimento da venda de discos e por promover a pirataria fonográfica em escala mundial. Neste recorte, conceitos como autoria, direito autoral e outros tem de ser repensados à luz desta tecnologia ao mesmo tempo em que se discute seu potencial criativo e sua capacidade de democratizar a produção sonora.

The main objective of this paper – resulting from an academic speech at UFG (Universidade Federal de Goiás) -is to outline the importance of Thomas Hobbes’ most known political work: Leviathan. Taking the figure of a big marine monster, quite in the same sense of the biblical metaphor used in the dialogue between God and Job to introduce the danger or the benefit of a big power controlled by men, Hobbes’s arguments terrorized the Church but helped in creating new ways (...) of thinking so to conceive the modern state. In the same movement, many other “demons” emerged to fight against religious power and also other forms of totalitarianism. Nevertheless, even shocking our conventional assumptions, Hobbes’ political work may be considered – among other liberal thinkers – a defense of individualism and many other aspects of civil order, which make him one of the most important contributor to modernity and also an essential source to think about our reality.

Benchmarking automated theorem proving (ATP) systems using standardized problem sets is a well-established method for measuring their performance. However, the availability of such libraries for non-classical logics is very limited. In this work we propose a library for benchmarking Girard's (propositional) intuitionistic linear logic. For a quick bootstrapping of the collection of problems, and for discussing the selection of relevant problems and understanding their meaning as linear logic theorems, we use translations of the collection of Kleene's intuitionistic theorems in the (...) traditional monograph "Introduction to Metamathematics". We analyze four different translations of intuitionistic logic into linear logic and compare their proofs using a linear logic based prover with focusing. In order to enhance the set of problems in our library, we apply the three provability-preserving translations to the propositional benchmarks in the ILTP Library. Finally, we generate a comprehensive set of reachability problems for Petri nets and encode such problems as linear logic sequents, thus enlarging our collection of problems. (shrink)

We consider two systems of constructive modal logic which are computationally motivated. Their modalities admit several computational interpretations and are used to capture intensional features such as notions of computation, constraints, concurrency, etc. Both systems have so far been studied mainly from type-theoretic and category-theoretic perspectives, but Kripke models for similar systems were studied independently. Here we bring these threads together and prove duality results which show how to relate Kripke models to algebraic models and these in turn to the (...) appropriate categorical models for these logics.

Este artigo tem como objetivo abordar uma intervenção realizada nas turmas do primeiro ano do ensino médio de uma escola localizada na cidade de Ipu-Ceará no ano de 2018, na disciplina de filosofia, com o tema ''Mito da caverna de Platão''. Assim, foram feitas leituras em sala de aula de alguns trechos do livro A República de Platão que aborda o tema, juntamente com o livro didático Filosofando: Introdução à filosofia das autoras Maria Lúcia de Arruda Aranha e Maria Helena (...) Pires Martins com o intuito de referenciar as cavernas contemporâneas. Deste modo, foi utilizado o método de ensino cuja intenção era a de apresentar livros e recursos audiovisuais para fins educacionais. Com a compreensão do mito da caverna de Platão, portanto, conseguimos vinculá-lo a um assunto da realidade dos alunos: a indústria da beleza que padroniza uma determinada forma de comportamento nos indivíduos, causando-lhes sérios problemas físicos e psicológicos. Para sustentar essa ideia, trabalhou-se com dois videoclipes das cantoras Beyoncé (Pretty Hurts) e Colbie Caillat (Try) na tentativa de despertar a reflexão da necessidade de autovalorização e aceitação física, em um distanciamento das cavernas patriarcais. Enfim, esse artigo manifesta uma enorme contribuição para os jovens do ensino médio, especialmente, na sua autoaceitação e formação identitária na medida em que compreendem os padrões como formas de aprisionamentos. Assim, conclui-se que estas discussões são relevantes por despertarem temas caros e reais aos jovens, tanto que promovem adoecimentos psicológicos. O propósito é o de expandir a discussão de tal forma que eles mesmos possam dialogar sobre o assunto. (shrink)
