Ekphrasis through otherness: the transformation of imagery in Derek Walcott's White Egrets
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Letras/Inglês e Literatura Correspondente, Florianópolis, 2015.Abstract : Opposing the contemporary literary reductionism of ekphrasis to a verbal representation of a painting, a sculpture, a drawing, or a photograph, this research views otherness as the object of contemplation. Through the present rereading of ekphrasis, the investigation will seek 1) to analyze how the ekphrastic characteristics of Walcott`s poetry in his latest work White Egrets promote more companionship than antagonistic views between poetry and painting, and; 2) to analyze how ekphrasis transforms the imagery of Derek Walcott`s créole identity into an aesthetic object of contemplation, depicting it in the similar way of a work of art. More specifically, the discussion analyses how the cultural relations/representations between the self and the other provide an ?ekphrastic situation? for Derek Walcott in the Caribbean?s complex colonial legacy. The poet`s ekphrastic act to render private and personal identity intimacies will lean on the nonfixity of the image, or its motion in stasis. The main theoretical concepts that sustain this investigation are drawn from the works of W.J.T. Mitchell (1980, 1986, 1994, 1996), Cheeke (2008), Loizeaux (2008), and Hall (1989, 1993, 1996, 1997).Opondo-se ao reducionismo literário contemporâneo de que a écfrase seja somente uma representação verbal de uma pintura, uma escultura, um desenho ou uma fotografia, esta pesquisa vê a própria alteridade como objeto de contemplação. Através desta releitura da écfrase, a presente investigação visa 1) analisar como as características ecfrásticas da poesia de Derek Walcott em sua última coleção de poesias intitulada White Egrets (Garças Brancas) propiciam mais companheirismo que visões antagônicas entre poesia e pintura, e; 2) analisar como a écfrase transforma a imagem da identidade crioula de Derek Walcott em um objeto estético de contemplação, retratando-a de uma forma semelhante a uma obra de arte. Mais especificamente, a discussão analisa como as relações/representações culturais entre o eu-individual e o outro propiciam uma  situação ecfrástica para Derek Walcott no complexo legado colonial Caribenho. O ato ecfrástico do poeta ao relatar aspectos privados e pessoais de sua identidade revelar-se-á embasado na infixidez da imagem, ou seja, seu imobilismo em movimento. Os principais conceitos teóricos que sustentam esta investigação foram retirados das obras de W.J.T. Mitchell (1980, 1986, 1994, 1996), Cheeke (2008), Loizeaux (2008), e Hall (1989, 1993, 1996, 1997)
Proline-rich tyrosine kinase 2 mediates gonadotropin-releasing hormone signaling to a specific extracellularly regulated kinase-sensitive transcriptional locus in the luteinizing hormone beta-subunit gene
No full textG protein-coupled receptor regulation of gene transcription primarily occurs through the phosphorylation of transcription factors by MAPKs. This requires transduction of an activating signal via scaffold proteins that can ultimately determine the outcome by binding signaling kinases and adapter proteins with effects on the target transcription factor and locus of activation. By investigating these mechanisms, we have elucidated how pituitary gonadotrope cells decode an input GnRH signal into coherent transcriptional output from the LH beta-subunit gene promoter. We show that GnRH activates c-Src and multiple members of the MAPK family, c-Jun NH2-terminal kinase 1/2, p38MAPK, and ERK1/2. Using dominant-negative point mutations and chemical inhibitors, we identified that calcium-dependent proline-rich tyrosine kinase 2 specifically acts as a scaffold for a focal adhesion/cytoskeleton-dependent complex comprised of c-Src, Grb2, and mSos that translocates an ERK-activating signal to the nucleus. The locus of action of ERK was specifically mapped to early growth response-1 (Egr-1) DNA binding sites within the LH beta-subunit gene proximal promoter, which was also activated by p38MAPK, but not c-Jun NH2-terminal kinase 1/2. Egr-1 was confirmed as the transcription factor target of ERK and p38MAPK by blockade of protein expression, transcriptional activity, and DNA binding. We have identified a novel GnRH-activated proline-rich tyrosine kinase 2-dependent ERK-mediated signal transduction pathway that specifically regulates Egr-1 activation of the LH beta-subunit proximal gene promoter, and thus provide insight into the molecular mechanisms required for differential regulation of gonadotropin gene expression

Chiral nonanalytic behaviour: The Edinburgh Plot
No full textCopyright © 2003 Published by Elsevier B.V.The Edinburgh Plot is a scale independent way of presenting lattice QCD calculations over a wide range of quark masses. In this sense it is appealing as an indicator of how the approach to physical quark masses is progressing. The difficulty remains that even the most state of the art calculations are still at quark masses that are too heavy to apply dimensionally-regulated chiral perturbation theory. We present a method allowing predictions of the behaviour of the Edinburgh plot, in both the continuum, and on the lattice.Stewart V. Wright, Derek B. Leinweber and Anthony W.

Application of metamaterial-inspired resonators in compact microwave displacement sensors
No full textThere is an emerging interest in the application of metamaterial-inspired resonators for the realization of smart sensors. This paper briefly describes two main categories of metamaterial-inspired displacement sensors, namely, the displacement sensors based on shift in the resonance frequency, and sensors based on changes in the depth of resonance. The paper also highlights the advantages and disadvantages of each category in terms of dynamic range, sensitivity, compactness, and robustness to noise and changes in ambient conditions.Ali K.

Finite-Volume Hamiltonian Method for ππ Scattering in Lattice QCD
No full textWithin a formulation of pi pi scattering, we investigate the use of the finite-volume Hamiltonian ap- proach to resolving scattering observables from lattice QCD spectra. We consider spectra in the centre-of-mass and moving frames for both S- and P-wave cases. Furthermore, we investigate the multi-channel case. Here we study the use of the Hamiltonian framework as a parametrization that can be fit directly to lattice spectra. Through this method, the hadron properties, such as mass, width and coupling, can be directly extracted from the lattice spectra.Jia-Jun Wu, T.-S. Harry Lee, Derek B. Leinweber, A. W.

Structure of the Roper resonance from lattice QCD constraints
No full textPublished 29 May 2018Two different effective field theory descriptions of the pion-nucleon scattering data are constructed to describe the region of the Roper resonance. In one, the resonance is the result of strong rescattering between coupled meson-baryon channels, while in the other the resonance has a large bare-baryon (or quark-modellike) component. The predictions of these two scenarios are compared with the latest lattice QCD simulation results in this channel. We find that the second scenario is not consistent with lattice QCD results, whereas the first agrees with those constraints. In that preferred scenario, the mass of the quarkmodel- like state is approximately 2 GeV, with the infinite-volume Roper resonance best described as a resonance generated dynamically through strongly coupled meson-baryon channels.Jia-jun Wu, Derek B.
