description: The Fu-Yau equation is an equation introduced by J. Fu and S.T. Yau as a generalization to arbitrary dimensions of an ansatz for the Strominger system. As in the Strominger system, it depends on a slope parameter $α'$. The equation was solved in dimension $2$ by Fu and Yau in two successive papers for $α'>0$, and for $α'<0$. In the present paper, we solve the Fu-Yau equation in arbitrary dimension for $α'<0$. To our knowledge, these are the first non-trivial solutions of the Fu-Yau equation in any dimension strictly greater than $2$.

description: A charge-density wave (CDW) state has a broken symmetry described by a complex order parameter with an amplitude and a phase. The conventional view, based on clean, weak-coupling systems, is that a finite amplitude and long-range phase coherence set in simultaneously at the CDW transition temperature T$_{cdw}$. Here we investigate, using photoemission, X-ray scattering and scanning tunneling microscopy, the canonical CDW compound 2H-NbSe$_2$ intercalated with Mn and Co, and show that the conventional view is untenable. We find that, either at high temperature or at large intercalation, CDW order becomes short-ranged with a well-defined amplitude that impacts the electronic dispersion, giving rise to an energy gap. The phase transition at T$_{cdw}$ marks the onset of long-range order with global phase coherence, leading to sharp electronic excitations. Our observations emphasize the importance of phase fluctuations in strongly coupled CDW systems and provide insights into the significance of phase incoherence in `pseudogap' states.

#DİRENHAMİLE: Pregnancy, Morality, and Resisting Discourses of Seclusion at the Gezi Park Protests

description: Millions joined Turkey’s 2013 Gezi Park protests, which were characterized by demonstrators’ steady creation of visual materials dissenting against the government. A subsection of pregnant protesters, who in June began tagging social media posts with #DİRENHAMİLE (#RESISTPREGNANT), critiqued both the government’s pronatalism and efforts of social conservatives to keep visibly-pregnant women secluded. This visual culture analysis draws upon semiology and discourse analysis methods to examine two paradoxes complicating #DİRENHAMİLE protest images: First, by leveraging pregnancy to critique pronatalism protesters risked reifying ideas about fertility being the primary source of women’s value. Second, their performances in public spaces critiquing seclusion rhetoric relied not upon assertions of individuality but on traditional social codes honoring mothers as childbearers. I work to better understand the impact #DİRENHAMİLE imagery has on challenging discourses aimed at controlling women’s bodies while accounting for the limitations of activism relying upon entrenched conceptualizations of pregnancy to illustrate its arguments.
Amor como em casa: o lugar da família (e) dos afetos na Literatura Infantil contemporânea
Creators: name: Mendes, Teresa
Publisher: name: Aprender
Year: 2013

description: Este artigo pretende demonstrar que a literatura infantil contemporânea é um lugar de afetos, onde moram as palavras e as imagens criando uma atmosfera poética que contribui para a formação estético-literária das crianças (pré)leitoras, um lugar repleto de sentidos que crianças e potenciais leitores adultos vão (re)construindo com a sua particular forma de ver e de sentir. Pretende-se igualmente demonstrar que, apesar de ainda predominar a visão nostálgica e conservadora da família, a literatura infantil apresenta igualmente novos modelos familiares, incorporando temas tradicionalmente considerados tabu, como a homossexualidade, o divórcio e a adoção, com naturalidade e sem falsos moralismos, no respeito pela inteligência e pela sensibilidade do público infantil.

description: Nesta comunicação, apresentamos um estudo longitudinal realizado com um grupo de crianças desde o pré-escolar até ao 2.º ano de escolaridade do Ensino Básico. Pretende-se perceber a importância do conto infantil enquanto fonte de imagens que a criança pode signifi car, transformando-as em imagens mentais, que fi cam disponíveis para serem usadas, criando circuitos neuronais, valorizando a vertente emocional do conhecimento e da aprendizagem, pela signifi cação promotora do bem-estar e incentivadora da regulação do afeto no desenvolvimento humano. O estudo pretende contribuir para o conhecimento sobre o conto infantil, como fonte de conhecimento e de vivências emocionais, como organizador das relações interpessoais e como laboratório de experimentação para a elaboração dos afetos, apresentando igualmente pistas para uma refl exão sobre o papel do educador/adulto no desenvolvimento da criança. A principal conclusão encontrada foi que as crianças deste estudo apresentavam uma elaboração mental (pensamento/resposta) com recurso a uma estratégia de equilibração emocional (resposta adaptativa).

description: This paper presents results from the design and testing of an educational version of Quantum Moves, a Scientific Discovery Game that allows players to help solve authentic scientific challenges in the effort to develop a quantum computer. The primary aim of developing a game-based platform for student-research collaboration is to investigate if and how this type of game concept can strengthen authentic experimental practice and the creation of new knowledge in science education. Researchers and game developers tested the game in three separate high school classes. The tests were documented using video observations of students playing the game, qualitative interviews, and qualitative and quantitative questionnaires. The focus of the tests has been to study players motivation and their experience of learning through participation in authentic scientific inquiry. In questionnaires conducted in the two first test classes students found that the aspects of doing real scientific research and solving physics problems were the more interesting aspects of playing the game. However, designing a game that facilitates professional research collaboration while simultaneously introducing quantum physics to high school students proved to be a challenge. A collaborative learning design was implemented in Class 3, where students were given expert roles such as experimental and theoretical physicists. This significantly improved the students feeling of learning physics compared to Class 1 and 2. Overall the results presented in this paper indicate that the possibility of participating in authentic scientific experiments, which this class of games opens, is highly motivating for students. The findings also show that the learning design in the class setting must be considered in order to improve the students' experience of learning and that various design challenges remain to be addressed further.

description: Shifting from traditional hazard-based food safety management toward risk-based management requires statistical methods for evaluating intermediate targets in food production, such as microbiological criteria (MC), in terms of their effects on human risk of illness. A fully risk-based evaluation of MC involves several uncertainties that are related to both the underlying Quantitative Microbiological Risk Assessment (QMRA) model and the production-specific sample data on the prevalence and concentrations of microbes in production batches. We used Bayesian modeling for statistical inference and evidence synthesis of two sample data sets. Thus, parameter uncertainty was represented by a joint posterior distribution, which we then used to predict the risk and to evaluate the criteria for acceptance of production batches. We also applied the Bayesian model to compare alternative criteria, accounting for the statistical uncertainty of parameters, conditional on the data sets. Comparison of the posterior mean relative risk, $E(\mathit{RR}|\mathrm{data})=E(P(\mathrm{illness}|\mathrm{criterion is met})/P(\mathrm{illness})|\mathrm{data})$, and relative posterior risk, $\mathit{RPR}=P(\mathrm{illness}|\mathrm{data, criterion is met})/P(\mathrm{illness}|\mathrm{data})$, showed very similar results, but computing is more efficient for RPR. Based on the sample data, together with the QMRA model, one could achieve a relative risk of 0.4 by insisting that the default criterion be fulfilled for acceptance of each batch.

Dynamics and Stability of Shock Waves in Granular Gases Undergoing Activated Inelastic Collisions

Subjects: shock waves

description: The present work investigates the dynamics and stability of shock waves in granular gases. The problem was modelled for a piston propagating into a system of disks that can undergo inelastic collisions if an impact threshold is exceeded. The model was addressed numerically at the microscopic and macroscopic levels. The molecular dynamics methodology employed the Event-Driven Molecular Dynamics method, and the continuum model was formulated using the Navier-Stokes equations for granular gases with the transport terms of Jenkins and Richman and a modified cooling rate term. The inviscid steady state shock structure was derived and analyzed. The results indicated that a relaxing shock structure is expected for sufficiently strong shock waves. Beyond this limit the structure was shown to be independent of the initial energy, a finding similar to the strong shock approximation in molecular gases. One-dimensional simulations demonstrated that the molecular dynamics and continuum models yield similar evolutions and structures of the shock wave, validating the continuum description of this study. Two-dimensional results showed that sufficiently strong shock waves can exhibit multi-dimensional instability with high density non-uniformities and convective rolls within the structure, with the size of instabilities shown to scale with the relaxation length of the shock structure. Instabilities were observed with the continuum description only with the inclusion of statistical fluctuations to density mimicking the molecular model. The cases that were unstable were shown to be in a regime whereby statistical fluctuations can become important, following the description for this regime by Bird. Based on these findings, it is proposed that unstable shock behaviour can be observed for highly dissipative shock waves that yield short relaxation length scales, where fluctuations become important. The current work may shed light on unstable shock behaviour observed in dissipative gases, having implications for both granular media and molecular gases.

Tourisme du yoga et quête de soi en Inde : une ethnographie des yogis occidentaux à Rishikesh

description: Cette thèse porte sur le tourisme du yoga à Rishikesh en Inde, la capitale mondiale du yoga. Cette ville située au bord de la rivière du Gange dans la région de l’Himalaya en Inde accueille, à chaque année, des milliers de touristes en quête de yoga et de spiritualité qui espèrent vivre une expérience transformatrice, loin du “monde moderne”. L’objectif de cette thèse est de comprendre et d’expliquer les motivations et l’expérience des yogis occidentaux qui se rendent à Rishikesh pour y pratiquer le yoga. Plus précisément, il s’agira d’expliquer comment les logiques néolibérales et leurs implications multiples viennent s'articuler dans le tourisme du yoga en Inde, l’expérience des yogis occidentaux à Rishikesh et la quête du soi qui leur est liée. À travers mes observations et celles de 10 participants qui ont été interrogés pendant une recherche de 3 mois à l’ashram Anand Prakash, je chercherai à démontrer que le tourisme du yoga en Inde est en partie une façon de répondre au projet de soi que la logique néolibérale sous-tend. Il y aurait donc un paradoxe dans le fait de vouloir pallier aux conséquences de la “modernité” avec la quête de soi alors que cette quête dérive elle-même de logiques néo-libérales.

Recognition and repair of trans-syn II cyclobutane thymine dimer by mammalian excision nuclease indicate that the affinities of damage sensors do not dictate the repair efficiency
Creators: name: Hutsell, Stephanie Quinn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The trans-syn cyclobutane pyrimidine dimer is a minor, but biologically significant ultraviolet photoproduct that is produced primarily in single-strand DNA. The only known repair system for this lesion is nucleotide excision repair. In this study I investigated the recognition and repair of the trans-syn cyclobutane thymine dimer by mammalian excision nuclease. I find that the trans-syn cyclobutane thymine dimer is recognized by RPA, XPA, and XPC damage sensor proteins with high specificity comparable to that of the [6-4] photoproduct; however, this lesion is excised by the mammalian excision nuclease with efficiency comparable to that of the poorly recognized cis-syn cyclobutane pyrimidine dimer. These data suggest that kinetic factors, after the initial damage recognition step, play a major role in the overall catalytic proficiency of the mammalian excision nuclease.

description: The frog model starts with one active particle at the root of a graph and some number of dormant particles at all nonroot vertices. Active particles follow independent random paths, waking all inactive particles they encounter. We prove that certain frog model statistics are monotone in the initial configuration for two nonstandard stochastic dominance relations: the increasing concave and the probability generating function orders. This extends many canonical theorems. We connect recurrence for random initial configurations to recurrence for deterministic configurations. Also, the limiting shape of activated sites on the integer lattice respects both of these orders. Other implications include monotonicity results on transience of the frog model where the number of frogs per vertex decays away from the origin, on survival of the frog model with death, and on the time to visit a given vertex in any frog model.

description: The Euclid space mission, designed to probe evolution of the Dark Energy, will map a large area of the sky at three adjacent near-IR filters, Y, J and H. This coverage will also enable mapping source-subtracted cosmic infrared background (CIB) fluctuations with unprecedented accuracy on sub-degree angular scales. Here we propose methodology, using the Lyman-break tomography applied to the Euclid-based CIB maps, to accurately isolate the history of CIB emissions as a function of redshift from 10 < z < 20, and to identify the baryonic acoustic oscillations (BAOs) at those epochs. To identify the BAO signature, we would assemble individual CIB maps over conservatively large contiguous areas of >~ 400 sq deg. The method can isolate the CIB spatial spectrum by z to sub-percent statistical accuracy. We illustrate this with a specific model of CIB production at high z normalized to reproduce the measured Spitzer-based CIB fluctuation. We show that even if the latter contain only a small component from high-z sources, the amplitude of that component can be accurately isolated with the methodology proposed here and the BAO signatures at z>~ 10 are recovered well from the CIB fluctuation spatial spectrum. Probing the BAO at those redshifts will be an important test of the underlying cosmological paradigm, and would narrow the overall uncertainties on the evolution of cosmological parameters, including the Dark Energy. Similar methodology is applicable to the planned WFIRST mission, where we show that a possible fourth near-IR channel at > 2 micron would be beneficial.

description: Cette thèse analyse deux des quatre romans d’Éric Dupont dans une optique transculturelle en reprenant certains paradigmes propres aux Amériques et au changement sociétal dans le contexte de la mondialisation. Cette étude porte ainsi sur les romans La logeuse et La fiancée américaine, tous deux publiés aux Éditions Marchand de feuilles. L’intention de cette thèse est d’analyser par quel(s) moyen(s) cet auteur parvient à dresser un portrait d’un Québec et d’un Canada en changement dans le contexte des identités multiples et des Amériques transculturelles. Dans chacun des chapitres, l’objectif est de mettre au premier plan les paradigmes dualistes qui se confrontent continuellement dans les Amériques et de voir comment les personnages réagissent et vivent avec ces dualités. Ces paradigmes se produisent en fonction des trois valeurs propres au Québec soit la terre, la religion et la langue. De par son style d’écriture, Éric Dupont emploie divers éléments discursifs liés à ces paradigmes afin de peindre le portrait de la société québécoise qui, depuis la Révolution tranquille, a bien changé. Ce portrait changeant de la société n’est possible que dans la rencontre avec autrui et c’est à partir de ce principe que je tenterai, en conclusion à cette recherche, de déterminer dans quelle mesure le rapport aux autres favorise le développement d’une société transculturelle et comment cela peut être transposé au niveau littéraire.
Conjugate Gradient Acceleration of Non-Linear Smoothing Filters

description: The most efficient signal edge-preserving smoothing filters, e.g., for denoising, are non-linear. Thus, their acceleration is challenging and is often performed in practice by tuning filter parameters, such as by increasing the width of the local smoothing neighborhood, resulting in more aggressive smoothing of a single sweep at the cost of increased edge blurring. We propose an alternative technology, accelerating the original filters without tuning, by running them through a special conjugate gradient method, not affecting their quality. The filter non-linearity is dealt with by careful freezing and restarting. Our initial numerical experiments on toy one-dimensional signals demonstrate 20x acceleration of the classical bilateral filter and 3-5x acceleration of the recently developed guided filter.

description: This thesis seeks to analyze the “alternative” nature of organic and fair trade markets and whether they are truly challenging the neoliberal food system, using the case of Bolivian quinoa, traditionally a subsistence crop, to analyze the effects on producer livelihoods. Field research, conducted from April until August 2015, focuses on two areas in the Altiplano sur: the small community of Rodeo and the town of Salinas de Garcí Mendoza. The study uses a political ecology and historical materialist theoretical framework and an ethnographically oriented livelihoods approach, in order to better weave the macro-processes of power to producers’ struggles over their livelihoods. Though organic and fair trade markets are by no means revolutionizing quinoa production or relationships of production in Bolivia, they are providing better terms of trade for producers and allowing them to maintain more traditional, small scale modes of production and community levels of organization. In addition, field research helped facilitate a critical discussion about the challenges and opportunities afforded by these alternatives, talking directly to producers and tying their local difficulties to larger, structural realities: a humble first step in problematizing a common lived struggle.
Virtual Reality as a Clinical Modality for Retraining Balance and Mobility.

description: Physical rehabilitation of individuals who are experiencing a disabling illness or have survived a traumatic injury (i.e. stroke) must seek to train the body’s structures and functions to reduce disability (activity limitations, participation restrictions) (Stucki, 2005). Figure 1 represents a modified version of the International Classification of Functioning (ICF), Disability and Health (World Health Organization, 2002). This figure illustrates how, for example, a stroke impacts the body structures and functions (e.g. muscle recruitment) which influences the ability to complete activities (e.g. gait) ultimately restricting participation in all areas of life (e.g. employment). The ICF model presents a framework for clinical practice and rehabilitation research studies. Although it has been shown to be strongly correlated (Schmid, Van Puymbroeck, et al., 2013) the concept of function cannot always be directly correlated with the concept of quality of life (Stucki, 2005) as the individual may not perceive, for example, impaired balance and mobility as detrimental to their quality of life. However, reduced function does put an individual at further risk of complications including falls and injuries from compensatory mechanisms and therefore must be addressed. The focus of this thesis is the study of the potential benefits of an exercise modality (virtual reality) to encourage restoration of the body’s structures and functions for individuals post-stroke. As the individuals engage in physical rehabilitation through exercise, there may be improvements on the individual’s abilities as seen through measurements of the control of posture and walking. The thesis comprises four studies, two of which have been published in peer reviewed journals. The progression of studies attempts to characterize outcomes following the use of virtual reality training in clinical populations (dementia and stroke) to address impairments to the body structures and functions (e.g. mobility) as measured by both clinical measures of activity and laboratory based measures of balance and to elucidate a possible mechanism (focus of attention) that makes training in a virtual environment effective.
Calculation of multi-loop superstring amplitudes

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Multi-loop interaction amplitudes in the theory of the closed, oriented superstrings are obtained by the integration of local amplitudes which are represented by a sum of the spinning string local amplitudes. The last local amplitudes are given explicitly through super-Schottky group parameters and interaction vertex coordinates on the $(1|1)$ complex supermanifold. The integration is ambiguous under those replacements of the integration variables which admix Grassmann variables to the boson ones. So the calculation is guided by a preservation of local symmetries of the superstring. The obtained amplitudes are free from divergences and consistent with the world-sheet symmetries. The vacuum amplitude and 1-, 2- and 3-point amplitudes of massless states vanish once the integration over certin modular variables and interaction vertex coordinates.

Jornalismo na Web: Da Pirâmide Invertida à Pirâmide Deitada

description: Falar de jornalismo é falar da Pirâmide Invertida, uma técnica de redação centenária que tem resistido a todas as mudanças no jornalismo. Com o aparecimento da Internet, alguns dos pressupostos que levaram os jornalistas a adotar esta técnica de redação deixaram de fazer sentido devido às características do novo meio. Desde logo porque o espaço disponível num jornal Web deixa de ser finito, anulando a necessidade de escrever condicionado pela possibilidade de o editor ter de efetuar cortes no texto para o encaixar num determinado espaço. Por outro lado, o hipertexto permite ao utilizador definir percursos de leitura em função dos seus interesses pessoais pelo que a redação da notícia deve ter em conta esse fator. Recorrendo à técnica da Pirâmide Invertida, o jornalista organiza a notícia colocando a informação mais importante no início e o menos importante do final, pelo que o leitor apenas pode efetuar a leitura seguindo o roteiro definido pelo jornalista. Mas o que fariam os leitores se essa notícia fosse dividida em vários blocos de texto ligados através de links, dando-lhe a possibilidade de efetuar uma leitura pessoal? Para observar os percursos de leitura de notícias na Web organizou-se uma experiência onde se convidavam os leitores a efetuarem a leitura de uma notícia constituída por vários blocos de informação ligados através de hipertexto. A análise dos dados permite concluir que existem diferentes padrões de leitura, o que deixa antever a necessidade de adotar um novo paradigma na organização de informação de cariz jornalístico.

On iBGP Multicasting in Software Defined Networks

description: In the Internet today, learnt prefixes are forwarded within autonomous systems (ASs) over internal Border Gateway Protocol (iBGP) sessions. Existing schemes for iBGP routing include the full-mesh (FM) solution, route reflection (RR) solution and confederation. Optimal prefix routing and route diversity are the main strength of the FM solution. However, it is rarely employed in a large networks due to its deficiency in aspects including scalability and large Routing Information Base (RIB) size requirement of routers. This is due to the fact that routers in this topology are required to peer with every other router within the AS. To combat these challenges, the RR scheme provides solution for scalability by decreasing the iBGP sessions requirement. Notwithstanding, the RR solution has its own challenges which includes reduced route diversity, introduction of divergence and forwarding anomalies. Also, the FM optimality may be lost since the Route Reflectors are responsible for reflecting the learnt prefixes to their corresponding clients based on its partial view of the network. The concept of Software Defined Networking (SDN) entails decoupling of the control plane from the forwarding plane such that the control plane is logically centralized benefiting from an overall knowledge of the network for decision making. In this work, we propose a solution based on multicasting which employs relay nodes in the iBGP message dissemination. Our solution brings session management scalability and minimization of duplicate prefix announcement through elimination of peer sessions deemed unnecessary. SDN controller is employed to configure and coordinate the multicast tree.
Partisan or Quasi-Partisan?

description: Formally non-partisan judicial elections have traditionally been more-or-less bereft of partisanship, with votes and results hinging upon candidate quality (Schaffner et al., 2001; Dubois, 1980, 1978). However, regulations limiting judicial candidates' speech in formally non-partisan elections have fared poorly in the federal courts in the 2000s. This has lead to the rise of what I term quasi-partisan judicial elections, or formally non-partisan elections in which at least one of the candidates runs a campaign based on partisan appeals. I examine the effects of quasi-partisan campaigns on the structure of voting and find that precinct-level partisanship is a stronger predictor of judicial vote share in quasi-partisan elections than in truly non-partisan elections.
