Abstract:

This dissertation fills a gap in nonsupersessionist theologies by constructing a Christology that brings together Jesus' particular Jewish existence (his human nature) and his universal transcendence (his divine nature), while maintaining the equality, unity, and full participation of both natures. This Christology proposes that both natures interact in a relationship of multiple-formativity to constitute the one person of the Incarnation through 'contextual universalism' and 'overlapping membership.' Using frameworks from the areas of multicultural theory and political theory, this dissertation first identifies the processes by which classical and contextual Christologies negotiate difference in the Incarnation. In doing so, it exposes that Jesus' Jewishness is problematically supplanted as Christologies unite the two natures of Christ through assimilationism, a process undergirded by the presupposition that coexistent differences cause untenable conflict that can be resolved only through a single agent that homogenizes difference. Destabilizing this presupposition and counteracting its results, this project then constructs a new conceptual framework for Christology that simultaneously differentiates and unites the two natures without assimilating either nature or dispensing with Jesus' Jewish particularity. Building from Toni Erskine's work in international relations theory and her model of 'embedded cosmopolitanism,' this work proposes 'contextual universalism' for understanding the differentiated unity of the two natures. To accommodate this new understanding, Laurel C. Schneider's theological anthropology and Rita Dhamoon's theory of difference are brought together to define Jesus Christ's human nature as constituted of a unique constellation of multiple, relationally-engaged contexts. Through an integration of Bikhu Parekh's political theory and Mayra Rivera's theology, the divine nature is interpreted as the unassimilable and transcendent Other that protects and connects innumerable differences. This dissertation then adapts Erskine's concept of 'overlapping membership' to propose a Christology wherein the particular, Jewish, human nature and the universal, divine nature of Jesus Christ engage in a relationship of interactivity and multiple-formativity in the one person of the Incarnation.

Abstract:

Philosophiae Doctor - PhD This study will contribute to the substantial corpus of secondary scholarship on the life, ministry, and theology of the German theologian, church leader, and modern-day martyr Dietrich Bonhoeffer (1906-1945). Bonhoeffer’s legacy has also elicited considerable interest in the South African context, concerning a wide variety of themes such as the Confessing Church movement, secularisation, discipleship, confessing guilt, spirituality, and ethics. The critical question articulated by Bonhoeffer predominantly in his Letters and Papers from Prison, namely ‘Who is Jesus Christ, for us, today?’ has been raised by different generations of South African theologians in rapidly changing contexts. This study will concentrate on Bonhoeffer’s own Christology. The focus will be not so much on the significance of the life and ministry of Jesus Christ within a particular social context, but on how Bonhoeffer understands the person of Christ. More specifically, the problem investigated in this study is how Dietrich Bonhoeffer’s evolving views on the so-called ‘two natures’ of Christ should be understood. The Nicene confession,’ that Jesus Christ is Lord, that he is ‘truly God’ and ‘of one being with the Father, ’ prompted considerable reflection in Patristic Christianity. One crucial question was how the confession of the divinity of Christ reconciles with the humanity of Jesus of Nazareth portrayed so vividly in the canonical gospels. The formulation of the Council of Chalcedon, namely that one may speak of ‘two natures’ and ‘one person,’ has never been satisfactory and prompted further controversy but remains a point of reference in ongoing Christological debates to this day. The question, therefore, raised: How does Bonhoeffer understand the relationship between the ‘divine’ and the ‘human’ nature of Jesus Christ? This question is pertinent given the consistent Christological concentration in Bonhoeffer’s theology (even to the point of a Trinitarian reductionism), his increasing emphasis on a ‘this-worldly’ understanding of God’s transcendence and his consistent Lutheran intuition that the finite can indeed contain the infinite. Bonhoeffer’s Christology has been the subject of much scholarly interest. There is consensus that his Christology remains not only incomplete but also unresolved. A core problem in this regard is his understanding of the divine nature of Christ – which he assumes but of which he does not offer any full account. This study will contribute to the available literature by exploring Bonhoeffer’s understanding of the ‘two natures’ of Christ based on the primary and secondary research with specific reference to Sanctorum Communio (1927/1963), Act and Being (1930/1996), Christology, Discipleship (1937/1959), Ethics (1955, 6th edition and 2005, new critical edition) and Letters and Papers from Prison (2010). There has been considerable controversy in Bonhoeffer scholarship regarding the continuity and discontinuity in Bonhoeffer’s theological thinking from his student years to his death in 1945. It would, therefore, be wise to allow for Bonhoeffer’s ‘evolving’ views on the ‘two natures’ of Jesus Christ to speak for itself. This study will seek to describe and assess (in terms of Bonhoeffer’s sources and secondary scholarship) Bonhoeffer’s views in each of his main works to trace the developments in his thinking.

Abstract:

Natural convection in two-dimensional irregular cavities was simulated by numerically solving the steady-state conservation equations written in terms of stream function, vorticity and temperature dependent variables and for a general orthogonal coordinate system. It was assumed that the Boussinesq approximations were valid, that the fluid was Newtonian and that the properties other than density were constant. The use of orthogonal coordinates and the above set of dependent variables was found to have several advantages over the use of Cartesian or non-orthogonal systems and the set of primitive dependent variables (velocities, pressure and temperature). The body-fitted orthogonal coordinate system was numerically generated by means of the weak constraint method of Ryskin and Leal [26], Special forms of the Wood and second-order vorticity boundary conditions were derived for a general two-dimensional body-fitted orthogonal coordinate system. Finite difference techniques were used to solve the resulting set of differential equations. The effects of the mapping characteristics, the vorticity boundary conditions and the finite difference grid size on the accuracy of the natural convection solution were investigated first. For the cavity geometries studied,, it was observed that, except for grid boundary conditions which led to undesirable grids, most combinations of grid and vorticity boundary conditions gave results of acceptable accuracy (relative error less than one percent) as long as a sufficiently fine grid size (28x28 or finer) was employed. The effects of the cavity geometry and the Rayleigh number on natural convection were investigated in Part II. It was found that increasing the Rayleigh number always acted to enhance both the natural convection circulation and the heat transfer rate, a result which was easily explained by examining the source term of the momentum equation. The effect of the cavity geometry was more complex but these results could also be interpreted by examining the influence of the cavity shape in impeding or enhancing fluid circulation and the opposing effects of the distance between isothermal walls on conductive and convective heat transfer. The possibility of using a similar numerical procedure to simulate a melting or a freezing process was investigated in Part III. Numerical predictions of the circulating flow in the liquid phase of an ice forming process were obtained by digitizing the photographic image of a real ice interface and using the true non-linear relationship between density and temperature for water at low temperature. The numerical results were in reasonable agreement with the flow visualization experiments carried out by Eckert [42].

Religion M.A. This discussion aims to demonstrate how the project of identifying the nature of humanity is ongoing. The dominant models have their own flaws to contend with, and in the end we are still left uncertain of what constitutes our nature. Of the two views vying for prominence (dualism vs. materialism) neither is indubitable, nevertheless their are faithful proponents on each side. In a debate of belief vs. theory we see these seemingly disparate realms come together in a resignation to faith that their option is an adequate representation of human nature.

Abstract:

In this dissertation, I propose a reductive account of causation. This account may be stated as follows: Causation: c is a cause of e within a possibility horizon ℓ if a) c is process-connected to e, and b) e security-depends on c within ℓ. More precisely, my suggestion is that there are two kinds of causal relata: instantaneous events (defined in Chapter 4) and possibility horizons (defined in Chapter 5). Causation is a ternary relation between two actual instantaneous events - the cause c and the effect e - and a possibility horizon ℓ. I argue that causation has a dual nature: on the one hand, a cause must be connected to its effect via a genuine process; on the other hand, a cause must make a difference to its effect. The first condition - namely, the condition of process-connection (defined in Chapter 6) - captures the sense in which a cause must be connected to its effect via a genuine process. This condition allows my account to separate causation from mere correlation, distinguish genuine causes from preempted backups, and capture how a cause must be at the right level of detail relative to its effect (Chapter 7). The second condition - namely, the condition of security-dependence (defined in Chapter 8) - captures the sense in which a cause must make a difference to its effect. This condition allows my account to yield intuitively correct verdicts on the counterexamples to the transitivity and intrinsicness of causation, resolve the problem of profligate omissions, accommodate structurally isomorphic but causally different cases, and handle contrastive causal claims (Chapter 9 and 10). Finally, my proposed account of causation logically entails restricted versions of three important principles of causal reasoning concerning the sufficiency of counterfactual dependence for causation, and the transitivity and intrinsicness of causation (Chapter 11).

Abstract:

Mestrado em Química For the purpose of resolving the chemical heterogeneity of natural organic matter (NOM), comprehensive two-dimensional liquid chromatography (LC x LC) was employed for the first time to map the hydrophobicity and polarity vs. molecular weight (MW) distribution of the following complex organic mixtures: Suwannee River (SR-FA) and Pony Lake (PL-FA) Fulvic Acids, both obtained from the International Humic Substances Society, and water-soluble organic matter (WSOM) from atmospheric aerosols. Two methods have been developed using either a conventional reversed-phase silica column (RP-C18) or a mixed-mode hydrophilic interaction column (mixed-mode HILIC) in the first dimension, and a size-exclusion column (SEC) in the second dimension. The RP-C18 x SEC and mixed-mode HILIC x SEC fractions were screened on-line by UV at 254 nm, molecular fluorescence at excitation/emission wavelengths (Exc/Em) of 240/450 nm, and by evaporative light scattering. The MW distributions of these NOM samples were further characterized by number average molecular weight (Mn), weight average molecular weight (MW), and polydispersity (Mn/Mw). Findings suggest that the combination of two independent separation mechanisms is promising in extend the range of NOM separation. The complete range of Mw values obtained in this study varied within 745-2122 Da, 637-1950 Da, and 157-891 Da for the SR-FA, PL-FA and WSOM, respectively. The obtained results were associated to the different origin and formation pathways of the three NOM samples, which strongly influence their chemical composition and MW distribution. Com o objetivo de avaliar a heterogeneidade química da matéria orgânica natural (MON), foi aplicada pela primeira vez a técnica de cromatografia líquida compreensiva bidimensional (CL x CL) a três misturas orgânicas complexas: ácidos fúlvicos do Rio Suwannee (AF-RS) e do Lago Pony (AF-LP), ambos obtidos da Sociedade Internacional de Substâncias Húmicas, e matéria orgânica solúvel em água (MOSA) de aerossóis atmosféricos. Com esta nova técnica analítica, pretendeu-se efectuar a separação cromatográfica das amostras de MON tendo em conta a hidrofobicidade e polaridade vs. massa molar. Para o efeito, foram desenvolvidos dois métodos distintos, utilizando na primeira dimensão ou uma coluna de fase reversa convencional (C18) ou uma coluna de interação hidrofílica/fase reversa (HILIC, sigla inglesa), e na segunda dimensão uma coluna de exclusão por tamanhos (SEC, sigla inglesa). Os perfis cromatográficos das frações resultantes dos sistemas C18 x SEC e HILIC x SEC foram registados por três detetores: UV a 254 nm, fluorescência molecular a comprimentos de onda de excitação/emissão (Exc/Em) de 240/450 nm e detector evaporativo de dispersão de luz. A distribuição da massa molar das amostras foi caracterizada pelas grandezas massa molar média em número (Mn), massa molar média em peso (Mw), e índice de polidispersão (Mn/Mw). Os resultados obtidos sugerem que a combinação de dois mecanismos de separação independentes constitui um método promissor na separação de amostras de MON. A distribuição de Mw obtida neste estudo foi de 745 a 2122 Da, 637 a 1950 Da e 157 a 891 Da para as amostras de AF-RS, AF-LP e MOSA de aerossóis atmosféricos, respectivamente. A gama de valores obtidos para a distribuição de Mw foram associados às diferentes origens e mecanismos de formação das amostras de MON, os quais podem influenciar a respectiva composição química e distribuição de tamanhos moleculares.

Abstract:

L'analyse du domaine vise à identifier et organiser les caractéristiques communes et variables dans un domaine. Dans la pratique, le coût initial et le niveau d'effort manuel associés à cette analyse constituent un obstacle important pour son adoption par de nombreuses organisations qui ne peuvent en bénéficier. La contribution générale de cette thèse consiste à adopter et exploiter des techniques de traitement automatique du langage naturel et d'exploration de données pour automatiquement extraire et modéliser les connaissances relatives à la variabilité à partir de documents informels. L'enjeu est de réduire le coût opérationnel de l’analyse du domaine. Nous étudions l'applicabilité de notre idée à travers deux études de cas pris dans deux contextes différents: (1) la rétro-ingénierie des Modèles de Features (FMs) à partir des exigences réglementaires de sûreté dans le domaine de l’industrie nucléaire civil et (2) l’extraction de Matrices de Comparaison de Produits (PCMs) à partir de descriptions informelles de produits. Dans la première étude de cas, nous adoptons des techniques basées sur l’analyse sémantique, le regroupement (clustering) des exigences et les règles d'association. L'évaluation de cette approche montre que 69% de clusters sont corrects sans aucune intervention de l'utilisateur. Les dépendances entre features montrent une capacité prédictive élevée: 95% des relations obligatoires et 60% des relations optionnelles sont identifiées, et la totalité des relations d'implication et d'exclusion sont extraites. Dans la deuxième étude de cas, notre approche repose sur la technologie d'analyse contrastive pour identifier les termes spécifiques au domaine à partir du texte, l'extraction des informations pour chaque produit, le regroupement des termes et le regroupement des informations. Notre étude empirique montre que les PCMs obtenus sont compacts et contiennent de nombreuses informations quantitatives qui permettent leur comparaison. L'expérience utilisateur montre des résultats prometteurs et que notre méthode automatique est capable d'identifier 43% de features correctes et 68% de valeurs correctes dans des descriptions totalement informelles et ce, sans aucune intervention de l'utilisateur. Nous montrons qu'il existe un potentiel pour compléter ou même raffiner les caractéristiques techniques des produits. La principale leçon à tirer de ces deux études de cas, est que l’extraction et l’exploitation de la connaissance relative à la variabilité dépendent du contexte, de la nature de la variabilité et de la nature du texte Domain analysis is the process of analyzing a family of products to identify their common and variable features. This process is generally carried out by experts on the basis of existing informal documentation. When performed manually, this activity is both time-consuming and error-prone. In this thesis, our general contribution is to address mining and modeling variability from informal documentation. We adopt Natural Language Processing (NLP) and data mining techniques to identify features, commonalities, differences and features dependencies among related products. We investigate the applicability of this idea by instantiating it in two different contexts: (1) reverse engineering Feature Models (FMs) from regulatory requirements in nuclear domain and (2) synthesizing Product Comparison Matrices (PCMs) from informal product descriptions. In the first case study, we adopt NLP and data mining techniques based on semantic analysis, requirements clustering and association rules to assist experts when constructing feature models from these regulations. The evaluation shows that our approach is able to retrieve 69% of correct clusters without any user intervention. Moreover, features dependencies show a high predictive capacity: 95% of the mandatory relationships and 60% of optional relationships are found, and the totality of requires and exclude relationships are extracted. In the second case study, our proposed approach relies on contrastive analysis technology to mine domain specific terms from text, information extraction, terms clustering and information clustering. Overall, our empirical study shows that the resulting PCMs are compact and exhibit numerous quantitative and comparable information. The user study shows that our automatic approach retrieves 43% of correct features and 68% of correct values in one step and without any user intervention. We show that there is a potential to complement or even refine technical information of products. The main lesson learnt from the two case studies is that the exploitability and the extraction of variability knowledge depend on the context, the nature of variability and the nature of text

Abstract:

Bivariate relationships have previously been established between exposure to nature and individual well-being, prosocial behaviour, and a general sense of connectedness, and between a general sense of connectedness and connectedness to nature. However, no model has been proposed to account for the patterning of these bivariate relationships. Research examining the relationship between exposure to nature and materialism is also lacking. The present research addressed these gaps by: a) manipulating the degree to which participants noticed and paid attention to nature over a two-week period; b) measuring participants' levels of post-intervention well-being (i.e., net-positive affect, elevating feelings, and sense of meaning), general connectedness, prosocial behaviour, and materialism; and, c) examining the pattern of relationships between these variables. Participants were randomly assigned to take photographs of either natural or built scenes/features that evoked in them strong emotions, or they were assigned to a no-photograph control condition. Participants uploaded their photos to a research website and indicated what feelings were evoked by the scenes. Following the two-week period, participants completed post-intervention measures of the dependent variables. Results showed that noticing nature over the course of a two-week period had beneficial individual and social effects. Post-intervention levels of well-being (i.e., net-positive affect and feelings related to elevation), general connectedness, and prosocial behaviour were higher for participants in the nature condition, compared to participants in the built and control conditions. These effects were not moderated by trait levels of connectedness to nature or engagement with beauty, nor were they moderated by dosage of nature. Post-intervention levels of sense of meaning and materialism did not differ between conditions. Mediation analyses did not reveal significant mediation pathways. Irving K.

Abstract:

Cultures of two Dipteran flies (Calliphora vicina (R-D) and C. vomitoria (L.)) were established to answer questions in regards to responses to thermal and desiccation stress, effects of diapause and the mechanisms which underpin diapause. The findings are divided in to two sections. Unequivocal new findings – Calliphora vomitoria were seen to depend on water being present in culture medium for increased survival. Furthermore, C. vomitoria were found to have lower desiccation resistance than C. vicina. Larvae of C. vicina and C. vomitoria showed different cold tolerance strategies, with C. vicina being freeze-avoiding and C. vomitoria ‘partially’ freeze-tolerant. Metabolomics, using \(^1\)H-NMR, revealed that diapause and non-diapause had distinct metabolic profiles. Diapause larvae were seen to reduce energy synthesis from the Krebs cycle and increase glycolysis. Calliphora vicina and C. vomitoria also exhibited different diapause phenotypes; C. vicina entered a maternally regulated facultative diapause as an L3 larvae, Calliphora vomitoria had a less distinct diapause, with maternal conditions having little effect. Speculative new findings - Despite the above differences C. vicina and C. vomitoria were able to produce a viable cross, though field fresh C. vomitoria were not used, as such it cannot be confirmed if this could occur in the wild. Increased temperatures due to climate change may affect both phenology and survival of insects; C. vicina was seen to have a delayed induction to diapause and a reduction in the proportion entering diapause. Diapause conferred increased cold tolerance; therefore those insects that overwinter not in diapause may suffer increased mortality.

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2017. This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections. Cataloged from student-submitted PDF version of thesis. Includes bibliographical references (pages 53-56). Natural language is an intuitive medium for a human to communicate with a robot. Additionally, there are many tasks in areas such as manufacturing, military, and disaster response where communication is limited among the agents performing these tasks. Due to this limited communication, we focus on a protocol where most of the communication is done before and after the mission execution. As a first step in analyzing the effectiveness of this protocol, this thesis presents a two-phased approach to parsing natural language into an arbitrary formal logic. In the first phase, we aim to learn the generic structure of the logical expression associated with a natural language utterance. For example, if the sentence "Approach the target from the west" were to be parsed into the expression Approach(target;west), then the first phase would output a generic structure such as f(c0; c1), where f, c0, and c1 are placeholders for the actual values Approach, target, and west, respectively. In the second phase, we aim the learn how to assign the intended values to these placeholders. The method developed in this thesis is able to achieve an accuracy of 46% and 78% for the first and second phase of our natural language parser, respectively. With the help of our natural language parser, we can use the outputted logical expressions in future work to help in the analysis of the mission execution's success or failure. by Giancarlo Sturla.

I found that humpback whales were able to discriminate between the sounds of different killer whale ecotypes.

Abstract:

This thesis presents an investigation of the 4-methoxypyrrolic constituents of two South African marine invertebrates, the nudibranch Tambja capensis and the bryozoan Bugula dentata. Three known compounds tambjamine A (7), tambjamine E (13) and the tetrapyrrole (15) were isolated during this investigation. All three compounds were shown to be active against oesophageal cancer in accordance with the general anticancer and immunosuppressive properties observed for 4-methoxypyrrolic natural products. Tambjamine A (7), tambjamine E (13) and the tetrapyrrole (15), together with tambjamine K (21) and L (22) (previously isolated in our laboratory) were used as standards to quantitatively assess the presence of these tambjamines in T. capensis and B. dentata collected from three different sites along the South African coast. This study confirmed that B. dentata is the source of the 4-methoxypyrrolic natural products sequestered by T. capensis and eliminated the closely related bryozoan B. neritina as a source of these metabolites. The paucity of tambjamine L (21) and K (22) obtained in previous investigations of the sequestered chemistry of T. capensis prompted an attempt at the development of synthetic methodology that could be used to synthesize tambjamines in sufficient yield for in depth bioactivity studies. In order to by pass the extensively reported problems associated with the synthesis of this group of compound 3-methoxy-2-formylpyrrole (47), readily accessible from 3-methoxypyridine N-oxide (48), was used as the starting material in a singlet oxygen induced 2,2’ bipyrrole coupling reaction. Although 47 proved unreactive in this coupling reaction, when the N-Boc protected analogue of 47 was used, and the reaction worked up in the dark, the novel methyl 4-aza-5-oxo-6,6-di-(2-pyrrolyl)-2(Z)-hexenoate (57) was obtained in low yield. The physical properties of tambjamine (E) (13) and the tetrapyrrole (15) were investigated to further the understanding of the proposed oxidative DNA cleavage mechanism and to determine the potential of the 4-methoxypyrrolic natural products as photodynamic therapy agents.

Full text

Abstract:

In the age of next-generation sequencing, an increasing amount of high-quality genomic time-series data is becoming available. This has created new opportunities to provide a more precise inference of population genetic parameters and more accurate hypotheses-testing about the recent action of natural selection. However, most existing population genetic inference procedures are only applicable to one-locus problems or multi-locus problems assuming no linkage between different loci due to the difficulty of computing the likelihood of the time-series data of allele frequencies sampled from multiple linked loci. To address this, we propose a hidden Markov model to characterise the time-series data of allele frequencies and develop an efficient simulated based method to evaluate the likelihood. In the hidden Markov model, the underlying population is assumed to evolve under natural selection at two linked loci according to the Wright-Fisher diffusion, and the observations are implicitly modelled through independent multinomial sampling from the underlying population at each given time point. We evaluate the transition probability density of the Wright-Fisher diffusion and the likelihood of the time-series data of allele frequencies sampled from two linked loci through importance sampling. Our simulation-based method enables us to jointly estimate the selection coefficient, recombination rate, and other population genetic quantities of interest from the two-locus time-series data of allele frequencies and can be naturally extended to analyse the multi-locus time-series data of allele frequencies.

Abstract:

My research topic is the ontology of causation in Aristotle, with a view to also making a contribution to contemporary philosophy. I offer a new interpretation of Aristotle’s account of causation and perception. I argue that Aristotle understands the causal link in terms of a single complex entity which involves essentially two interdependent natures (e.g. an activity that grounds teaching and learning). Internally, such an entity has the same metaphysical structure as a line that grounds two vectors with opposite directions. But the causal entity, as opposed to the line and vectors, is itself ontologically dependent on the two substances that are in causal interaction. This is because the entity’s two natures are the realisation of two interdependent potentialities of the two substances (e.g. for teaching and learning). Aristotle builds a causal bridge between substances out of mutually realised potentialities of the two substances. Their mutual realisation binds them together into a net of ontological dependencies which delineates the boundary of the causal entity. In my thesis I describe the multifarious ontological dependencies and argue that Aristotle has made a unique contribution to the history of the analysis of causation by offering an ontological account of it in terms of potentiality-actuality and ontological dependence. Furthermore, Aristotle puts in use his theory of causation to account for the metaphysical status of what we call after Locke secondary properties, e.g. colours, sounds, etc. I reconstruct Aristotle’s theory of secondary properties in the light of my understanding of his two-in-one metaphysical model. I put Aristotle’s theory of causation as applied to his theory of perception to the test of whether it gives philosophical gains in contemporary philosophy in the field of the philosophy of mind. I engage with David Chalmers’ arguments against Primitivism – which is a new contemporary account of the metaphysics of colours. Primitivism is the account of colours philosophically most alike to Aristotle’s own one. I put forward my own original position on the metaphysics of colours.

Abstract:

Low frequency mechanical vibrations (<100 Hz) are naturally generated by skeletal muscles during voluntary contractions. Recording of these vibrations at the muscle surface are called surface mechanomyograms (S-MMGs). In this study, S-MMGs were recorded over a 3 x 5 grid of skin mounted accelerometers on the biceps brachii muscle during submaximal voluntary isometric contractions with the arm in a pronated position for ten healthy and young male subjects with no overt sign of neuromuscular diseases. For a given pair of accelerometers, the spatial coherence of S-MMG is a measure of the similarity of the S-MMG signals propagating between those two sensors. Two common techniques to estimate the spatial coherence for narrowband S-MMG signals, namely the magnitude squared coherence function and the maximum of the time-domain cross-correlation function, were found to yield similar results. In particular, high spatial coherence values were measured for sensor pairs aligned along the proximal to distal ends of the biceps, i.e. the longitudinal direction. On the other hand, the spatial coherence values for sensor pairs oriented perpendicular to the muscle fiber, i.e. along the transverse direction, were found to be significantly lower. This finding indicates that coherent S-MMGs were mainly propagating along the muscle fibers direction (longitudinal) of the biceps brachii within a frequency band varying between 10Hz to 50Hz. Additionally, the spatial coherence of S-MMGs along the longitudinal direction was found to decrease with increasing frequency and increasing sensor separation distance and to increase with contraction level varying between 20% to 60% of the maximum contraction level.

Abstract:

Natural Killer (NK) immune lymphocytes are mainly known to eliminate cancerous and virus infected cells. When they encounter another host cell, they utilize surface receptors to scan the target cell for telltale disease-associated ligands. Therefore, these receptors play a central role in regulating NK cell effector functions that include direct cytotoxicity and cytokine release. NKG2D and NCR1 are among the most studied NK receptors identified to date. NKG2D binds a range of stress induced MHC class I like ligands while NCR1 binds the viral protein, haemagglutinin, as well as unidentified tumour ligands. Knockout mouse models have highlighted the importance of these receptors in combating tumorigenesis, virus infections, and in the development of autoimmune disorders. The expression of these receptors is specific: NKG2D is expressed only on NK cells and a minority of T cell subsets while NCR1 is even more restricted to the NK lineage. Yet the basis behind the transcriptional regulation of NKG2D and NCR1 has remained a mystery. I have found genetic and epigenetic mechanisms that control the expression of the receptors, including involvement of a retrotransposon in regulation of the mouse Nkg2d gene. Luciferase assays were used to delineate crucial DNA elements such as promoters and enhancers. Bioinformatic and RNA expression techniques have led to the discovery of GABP, RUNX3 and RUNX1 as regulators of NKG2D and NCR1. The role of these transcription factors were verified using gel shift, chromatin immunoprecipitation, knockdown, dominant negative and overexpression experiments. My results shed light on transcription regulation of crucial NK receptors. At the same time, it allows me to make inferences on the NK genetic regulatory program.

Abstract:

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR PROGRAMA DE SUPORTE À PÓS-GRADUAÇÃO DE INSTS. DE ENSINO No mercado de gás natural (GN), muitos contratos incorporam flexibilidades no volume a ser entregue, conhecidas como opções de swing. Sujeitos a restrições, esses contratos concedem ao titular a opção de exercer o direito de receber volumes maiores ou menores de GN contratado, de acordo com as oscilações dos preços de mercado, dos indicadores econômicos e a demanda. Através das opções de swing é possível valorar as flexibilidades embutidas em um contrato de GN. As opções de swing fazem parte das chamadas opções exóticas, cujas características são específicas distinguindo-se das opções padrão. Um dos aspectos primordiais na avaliação de opções é determinar de que forma são tratadas as incertezas do contrato. No presente trabalho, o preço do GN é a principal fonte de incerteza e foi considerado estocástico seguindo o modelo de dois fatores de Schwartz e Smith (2000) com sazonalidade trimestral. As commodities, em geral, não são negociadas no mercado a vista, sendo negociadas nos mercados futuros. Por isso, para estimar os preços à vista do GN, usando os preços dos contratos futuros do Henry Hub negociados na NYMEX, foi preciso implementar o método do filtro de Kalman, que relaciona as variáveis não observáveis com os preços futuros de diversas maturidades. Como resultado principal, analisou-se o valor das cláusulas contratuais, ou seja, opções de swing que ajudam na necessidade de hedge de um mercado sujeito a incertezas. O apreçamento da opção foi realizado por meio do modelo de árvore binomial bi-variável em tempo discreto, desenvolvido por Hahn e Dyer (2011) para o modelo de Schwartz e Smith (2000). O valor da opção de swing foi positivo nos dois casos analisados, mostrando que essa opção tem valor e, portanto, deve ser cuidadosamente analisada para inclusão nos contratos de GN. As características do contrato analisado foram as mesmas especificadas em Jaillet et al.(2004). In energy markets, in particular, natural gas (NG), many contracts incorporate flexibility in the volume to be delivered. These contracts are known as swing options or take-or-pay contracts. Subject to restrictions, such contracts allow the option holder to exercise the right to receive greater or smaller amounts of NG contracted in accordance with market price, economic indicators and demand. Through swing options it is possible to value the flexibilities built into a contract for NG. Swing options are part of family called exotic options, which have unique distinguishing characteristics in comparison to standard options. One of the key aspects in the evaluation of options is to determine how they behave as a result of the uncertainties of the contract. In this work, the price of NG was the main source of uncertainty and was considered following the stochastic two-factor model of Schwartz and Smith (2000) with quarterly seasonality. Commodities in general are not traded in the spot market, but rather traded in futures markets. Therefore, to estimate the spot prices of NG, using the prices of futures contracts traded on NYMEX Henry Hub, it was necessary to implement the Kalman filter method, which relates the unobservable variables in the future prices of various maturities. As the primary focus, we analyzed the value of contractual terms, i.e. swing options that help to hedge in a market subject to uncertainties. The pricing of the option was made through the binomial tree model bi-variable in discrete time developed by Hahn and Dyer (2011) for the model of Schwartz and Smith (2000). The value of the swing option was positive in both cases analyzed, showing that this option has value and therefore should be carefully considered for inclusion in contracts of natural gas. The characteristics of the analysis were the same as specified in Jaillet et al. (2004).
