[pt] Este trabalho tem como objetivo central analisar comparativamente três dos principais romances distópicos escritos na primeira metade do século XX: We (1924) de Yevgeny Zamyatin, Brave New World (1932) escrito por Aldous Huxley e 1984 (1949) escrito pelo romancista e jornalista inglês George Orwell. Não se trata aqui de pensar apenas em como essas obras foram moldadas por um ou outro conjunto de pressões históricas, mas sim procurar refletir especialmente se e como essas obras também podem possuir uma dimensão propositiva comum a todas elas. Elabora-se, a partir desse esforço, a categoria de estética do prognóstico, no interior do próprio pensamento crítico e ensaístico de Aldous Huxley. Partindo da obra de Huxley e posterioremente testando a força dessa categoria de estética do prognóstico frente aos dois outros romances, fomos capazes de perceber como a ficção opera a construção de uma encenação que pretende ser mais do que mera encenação. Pretende ser ela mesma uma espécie de realismo do futuro, chamado por nós de realismo distópico. Mas esse realismo não encontra o ponto máximo de sua representação da realidade na literatura ao profetizar (prognosticar) os meios pelos quais a sociedade do futuro irá se desenvolver, mas sim nas tópicas centrais à construção de seus protagonistas: o amor e a morte. / [en] This work is mainly aimed at comparing three of the main dystopian novels written in the first half of the twentieth century: We (1924) by Yevgeny Zamyatin, Brave New World (1932) written by Aldous Huxley and 1984 (1949) written by the english novelist and journalist George Orwell. We re not only interested to think of how these works were shaped by either set of historical pressures, but rather trying to reflect especially if and how these works may also have a common propositional dimension to all of them. Draws up from that effort, the category of the aesthetic of prognosis, built inside the critical and essayistic thought of Aldous Huxley himself. Starting from the work of Huxley and then testing the strength of this category of aesthetic of prognosis compared to the other two novels, we were able to understand how fiction works to build a staging that aims to be more than mere acting. Want to be itself a kind of realism of the future, called by us the dystopian realism. But this realism did not find the peak of its representation of reality in literature prophesying (predicting) the means by which the society of the future will develop, but on the construction of the central protagonists issues: love and death.

"Art," besides being art, "is also philosophy," Aldous Huxley says in Vulgarity in Literature. Throughout the years in which he has been writing, Huxley has never lost sight of this dictum. His philosophy has ever formed an integral part of all that he has produced, and especially has it been basic in his novels. Because of the importance of philosophy to Huxley, the artist, I have aimed in this study at following the course of his changing philosophy. I have tried to present Huxley in his early years advocating a philosophy of meaninglessness and then, after becoming dissatisfied with such an interpretation of life, evolving a kind of pseudo-humanistic theory which he later discarded in favor of a mystical interpretation of the universe. In addition to showing the "what" of Huxley's philosophy, I have attempted to search out its "whys" as well. I have held his theories up to the light of the sociological background of his times and to the light of his own personality. That is, I have decided that the philosophy to which he holds and has held is subject ot the dictates of social change and to the dictates of his own nature.

The aim of the research is to provide a computationally efficient neural network model for the study of deep brain stimulation efficacy in the treatment of Parkinson's disease. An Izhikevich neuron model was used to accomplish this task and four classes of neurons were modeled. The parameters of each class were estimated using a genetic algorithm with a fitness function based on spike frequency as a function of input current. After computing the optimal parameters the neurons were interconnected to form the network model. The estimated parameters were capable of replicating the normal firing characteristics for each type of neuron, but failed to replicate richer spiking characteristics such as post-inhibitory bursting and tonic firing. Without these characteristics, the network was unable to produce biologically feasible results. Findings indicate the Izhikevich model relies heavily on manual tuning and must be trained under an extensive set of conditions to allow for the majority of spiking characteristics to be learned. The use of the Izhikevich model in a network simulation will always be limited to the characteristics trained on a single neuron. When connected to the network the neuron may be exposed to a variety of unlearned conditions and therefore may not be capable of replicating biologically realistic behavior. / Electrical and Computer Engineering

In this thesis, we introduce several closely related stochastic models which generalize the deterministic Hodgkin-Huxley formalism to an SDE framework. We provide analytical results on the existence and uniqueness of solutions as well as the exact formulas for the moments of a simplified model, with simplifications motivated by the experiments performed by Hodgkin and Huxley in their seminal paper.For more complicated models, we provide an approach for the approximation and simulation of solutions to the corresponding SDEs, and show several realizations of the sample paths and moments of these simulations to verify qualitative behavior in this case. All code for the project is written in the Julia language and can be obtained upon request by the reader.

This paper analyses Mr. Scogan and his treatment of women with the use of Althusser’s Marxist theory which (supposedly and in this case successfully) reveals the ideology which infuses every State and every larger social group. Feminist theory is then used to analyse his philosophy which influences both his utopia, “the Rational State”, as well as his treatment of women – the conclusion drawn after analysing several events or discussions in Crome Yellow, such as on the Home Farm, the Rational State and the Charity Fair was that Mr. Scogan is perhaps not representative of all men and certainly not of men (and men’s notions) at the timeof Crome Yellow’s publication, but he is representative of a stereotypical man who oppress women based on their femininity. The worst case scenario drawn was that Mr. Scogan could be a rapist of young virgins.

That was precisely the subject of Man s Place in Nature, a book by Thomas Henry Huxley (1825-1895) that became highly influential from the 1860s onwards. In addition, Huxley gave countless lectures, participated in hot public debates, and wrote essays and letters on that subject. The aim of the present study was to analyze contextual and epistemological features relative to Huxley s book. Following a mapping of the ideas on man s place in nature held in England in the first half of the 19th century up to the 1860s, Man s Place in Nature was subjected to epistemological analysis. Our results point to an overlapping of the ideas then formulated relative to zoological classification and appropriate criteria for comparison required for accurate grading of living beings, as e.g., the marks of animality . In this regard, Huxley prioritized the criteria provided by comparative anatomy and the current ideas on human races, as well as the traditional notions on the gradation of species and scale of nature , aiming at formulating a general law that would ensure the essential unity of humankind with the remainder of nature. Such general law was particularly necessary to demonstrate Huxley s hypothesis stating that there is no essential antithesis between human beings and the other animals, and that the physical, moral and mental differences between them do not suffice to posit an insurmountable gap between humankind and nature / O problema acerca do lugar do homem na natureza constituiu uma espécie de fio condutor ao redor do qual diversos conceitos foram formulados e várias teorias foram debatidas no contexto da Inglaterra vitoriana. Esse tópico foi encapsulado no título de uma obra muito influente a partir da década 1860, Man s Place in Nature (O lugar do homem na natureza), cujo o autor, Thomas Henry Huxley (1825-1895) ministrou palestras, debateu publicamente, escreveu ensaios e trocou cartas sobre o tema em questão. O objetivo do presente estudo foi explorar os aspectos contextuais e epistemológicos relacionados à referida obra de Huxley. Assim, foi feito um mapeamento das ideias sobre o lugar do ser humano na natureza na Inglaterra na primeira metade do século XIX até os anos 1860, seguido de uma análise primariamente epistemológica da obra de Huxley. Tal estudo nos permitiu identificar uma sobreposição de ideias acerca do processo de classificação zoológica, ou de critérios de comparação, como as marcas de animalidade , necessários para a correta hierarquização dos seres. Verificou-se que o uso desses critérios levou Huxley a invocar os fatos produzidos pela anatomia comparada, bem como as ideias contemporâneas sobre as raças humanas, além das ideias mais tradicionais sobre a gradação das espécies e a escala natural , no intuito de formular uma lei geral que assegurasse a unidade da humanidade com o resto do mundo natural. Essa lei geral era necessária para comprovar a hipótese de que não havia uma antítese essencial entre os seres humanos e os demais animais e que as diferenças existentes entre eles não eram suficientes para justificar a suposta incomensurabilidade física, moral e mental entre ambos

His translation, Contraponto (1934), is analyzed in the context of translation and ideology of Vargas Age, a nationalist and authoritarian government. The methodology is developed via cultural transferences, and it intends to comprehend the trajectory of Erico Veríssimo as a translator and remake the translation process of Point counter point. The profile of the translator Veríssimo is initially traced through his first experiences at Globe Magazine, where he published rapid translations, inventing pseudonyms for them. Later on, he published translations of books internationally known and the translation process occurred in an elevated and more elaborated standard. The route and the choice of Contraponto translation initially presented an editorial audacity of Veríssimo, who risked commercially, once the literary work was dense and the author was not known in Brazil. However, it was a decisive point to the translator Veríssimo and to the divulgation of Huxley in Brazil. Contraponto became a best-seller and an editorial milestone. It was published in the Nobel Collection, which brings to the ordinary reader and the intellectuals of that epoch the translation of literary works of international repercussion, raising and enriching culturally its public. The editorial policy of Globe in translating the world classics is linked to the nationalist ideals of Vargas in valuing the role of vernacular language and the education in the search for an identity for the Nation. In a selective textual analysis from the concepts of specific cultural items in translation by Aixelá and the Theory of Polisystems, it is highlighted that translation is marked by conservation strategy (repetition), in a tendency of adequacy. The translation of Veríssimo permits the visualization of marks of foreign culture. Moreover, it does not nationalize cultural specificities, adding new information to the reader. With the concepts of translation and ideology brought by Lefevere, it is understood that rewriting can be inspired by ideological motivations. Therefore, it could be associated that Contraponto approaches ideological questions related to fascism, linking them to Vargas Age, with which had totalitarian similarities. / Este trabalho analisa Erico Veríssimo enquanto tradutor na Editora Globo da obra Point counter point (1928), de Aldous Huxley, intitulada Contraponto (1934), no contexto da tradução e ideologia no Regime Vargas, governo autoritário e nacionalista. A metodologia é desenvolvida via transferências culturais, buscando compreender a trajetória de Erico Veríssimo como tradutor e refazer o processo tradutório da obra de Huxley. O perfil do tradutor Veríssimo é traçado inicialmente através de suas primeiras experiências na Revista do Globo, onde lançava no mercado traduções rápidas, inventando pseudônimos para as mesmas; e, posteriormente, com a publicação de traduções de obras de renome internacional, onde o processo tradutório ocorria num padrão elevado e mais elaborado. O percurso e a escolha da tradução Contraponto representam inicialmente uma ousadia editorial de Veríssimo, arriscando-se comercialmente, uma vez que a obra era densa e o autor desconhecido no Brasil; e, de fato, foi um ponto decisivo para Veríssimo tradutor e para a divulgação de Huxley no Brasil. Contraponto foi sucesso de vendas e um marco editorial, publicado na coleção Nobel, que levava ao leitor médio e aos intelectuais da época as traduções de repercussão internacional, formando e enriquecendo culturalmente seu público. A política editorial da Globo de traduzir os clássicos mundiais coaduna com os ideais nacionalistas de Vargas de valorizar o papel da língua vernácula e da educação na busca da identidade da Nação. Numa análise textual seletiva a partir dos conceitos dos itens culturais específicos em tradução trazidos por Aixelá e da teoria de polissistemas, destacamos que a tradução é marcada pela estratégia de conservação (repetição), numa tendência à adequação. Sua tradução permite a visualização das marcas da cultura estrangeira, não nacionaliza especificidades culturais, acrescentando informações novas ao leitor. Com os conceitos de tradução e ideologia advindos de Lefevere, entendemos que a reescritura pode ser inspirada por motivações ideológicas, logo podemos associar o fato de Contraponto tratar de questões ideológicas ligadas ao fascismo com o Governo Vargas, que possuía semelhanças totalitaristas.

Muitos deles são fundamentados em sistemas de equações diferenciais ordinárias (EDOs), isto é, baseiam-se em conjuntos de igualdades que envolvem variáveis dependentes, suas derivadas de primeira ordem e a variável independente. Neste trabalho, estudamos a modelagem da geração do potencial de ação em células excitáveis, como os neurônios. Existem dois modelos tradicionais e pioneiros que se destacam nessa área: Hodgkin-Huxley e FitzHugh-Nagumo. O objetivo desta dissertação é avaliar a possibilidade de modelar a geração do potencial de ação via uma única equação diferencial com atraso. Equações diferenciais com atraso são importantes por sua capacidade em reproduzir uma grande diversidade de fenômenos. Porém, seu uso na modelagem do potencial de ação de células excitáveis é ainda incipiente. Nesta dissertação, o método usado para alcançar este objetivo se baseou no desenvolvimento, inicialmente, de uma equação integro-diferencial que aproxima o sistema de EDOs. Em seguida, desenvolvemos uma aproximação para as integrais que usa termos tanto no instante atual quanto em instante anteriores, i.e., atrasados no tempo. Dessa forma, mostramos que é possível aproximar cada um dos sistemas de EDOS dos modelos de Hodgkin-Huxley e FitzHugh-Nagumo por uma única equação diferencial com atraso. Por fim, estes novos modelos são comparados com os originais, e são apontadas direções para a continuidade desta pesquisa. / To represent different phenomena and systems mathematical models are widely used. Many of them are based on systems of ordinary differential equations (ODEs), that is, they are based on sets of equalities involving dependent variables, their derivatives of first order and the independent variable. In this work, we study the modeling of action potential generation in excitable cells, such as neurons. There are two traditional and pioneering models that stand out in this area: Hodgkin-Huxley and FitzHugh-Nagumo. The objective of this dissertation is to evaluate the possibility of modeling the generation of the action potential via a single differential equation with delay. Differential equations with delay are important because of their capacity to reproduce a great diversity of phenomena. However, its use in modeling the action potential of excitable cells is still incipient. In this dissertation, the method used to achieve this goal was based on the development, initially, of an integral-differential equation that approximates the ODE system. Next, we develop an approximation for integrals that uses terms at both the current instant and the previous instant, i.e., time delayed. Thus, we show that it is possible to approximate each of the ODEs systems of the Hodgkin-Huxley and FitzHugh-Nagumo models by a single differential equation with delay. Finally, these new models are compared with the original ones, and directions are indicated for future works.
