Por arqueólogos, historiadores de la Antigüedad y epigrafistas de época romana y fenicio-púnica de la cultura gaditana. Las líneas de investigación y aportaciones de M. J. Jiménez Cisneros no han sido todavía suficientemente explotadas. Por otro lado, la historia de la Arqueología gaditana delos años cuarenta a los setenta del pasado siglo tiene también en estos fondos documentos e indicios importantes de la actividad desempeñada en la provincia.The Archive of the University of Cádiz is honored with the deposit of the Archaeological Fund of Mª Josefa Jiménez Cisneros donated by her family, a fund that deserves to be known by archaeologists, historians of Antiquity and epigraphists of the Roman and Phoenician-Punic times of Gadir/Gades. The lines of research and contributions of M. J. Jiménez Cisneros have not yet been sufficiently exploited.
The history of the Archeology since the forties to the
seventies of the last century also has in these funds important documents of its activity in Cádiz

Measurements of the type series. The measurements of the type series are presented in Table 1. Natural history. Individuals were captured during the night, in disturbed forest, on grass and bushes up to 2 meters above ground. ICN 49789 was collected in a bromeliad 60 cm above the ground. The males have pale yellow testes and the females have a mass of pale eggs. The specimens produce an unpleasant odor when manipulated. Distribution. Known from Valle de Sibundoy in San Francisco and Santiago municipalities at elevations of 2060–2550 m. (Fig. 3). Remarks. Lynch and Suárez-Mayorga (2003) proposed the formation of a clade that includes E. chloronotus Lynch, E. corniger and E. vicarius Lynch and Ruiz-Carranza. They also proposed that if the sharply concave canthus rostralis is a synapomorphy, E. corniger and E. vicarius are sister species. Eleutherodactylus zoilae also presents the sharply concave canthus rostralis; consequently, if the supposition of Lynch and Suárez-Mayorga (2003) is correct, E. zoilae would form a clade with E. corniger and E. vicarius.Published as part of Mueses-Cisneros, Jonh Jairo, 2007, Two new species of the genus Eleutherodactylus (Anura: Brachycephalidae) from Valle de Sibundoy, Putumayo, Colombia, pp. 35-43 in Zootaxa 1498 on pages 40-43, DOI: 10.5281/zenodo.17707

Escher's room
No full text[EN] This article is born as a game in which art, geometry, physics and mathematics are related to reveal a space that remained trapped in the form of a reflection in one of the best-known works of the fascinating Dutch artist M. C. Escher, entitled: Hand with reflecting sphere. This work is a self-portrait in which the artist reproduces his own hand holding a specular globe in which he himself is reflected sitting in his Rome studio. Thanks to the meticulousness and perfection with which the artist executed his works, it has been possible to restore this space from his reflection, using software designed specifically for the occasion that transforms the reflection into a spherical panorama of the scene, in which we can feel immersed together with the disappeared artist, thanks to the novel techniques and visors of virtual reality.[ES] Este artículo nace como un juego en el que se relacionan arte, geometría, física y matemáticas para desvelar un espacio que permanecía atrapado en forma de reflejo en una de obras más conocidas del fascinante artista neerlandés M.

Esta obra es un autorretrato en el que el artista reproduce su propia mano sujetando un globo especular en el que él mismo se ve reflejado sentado en su estudio de Roma. Gracias a la meticulosidad y a la perfección con la que el artista ejecutaba sus obras ha sido posible restituir este espacio a partir de su reflejo, mediante un software diseñado específicamente para la ocasión que transforma el reflejo en un panorama esférico de la escena, en la que podremos sentirnos inmersos junto al desaparecido artista, gracias a las novedosas técnicas y visores de realidad virtual.Cabezos Bernal, PM.; Cisneros Vivó, JJ.

Invited tutorial: Metaheuristic optimization with applications to computational vision for humanoid robots
No full textNature-inspired computing studies the application of biology concepts to solve demanding problems by assuming that natural world experiences may hold some answers to real-life technical challenges. Engineering is being challenged everyday by more complex, large, ill-structured and distributed systems yielding a renovated interest on the subject. However, nature is providing simple structures and organizations which are capable of dealing with most complex systems and tasks. Metaheuristic optimization techniques aims to mimic collective intelligence from several nature-inspired approaches in order to propose a solution for several problems exhibiting a complex behavioral pattern. The overall approach follows the idea that a system is composed of decentralized individuals that may effectively interact to other elements according to their localized knowledge, i.e. their individual interaction. Special kinds of artificial collective-individuals are the elements created by analogy with bees, charged particles or the human immunology system. � 2011 Author
Switch-less frequency-domain multiplexing of GFET sensors and low-power CMOS frontend for 1024-channel μECOG
No full textThis paper presents a novel frequency-domain multiplexing scheme of liquid-gate GFET sensors for large-scale μECoG recording. The proposed technique allows the hybrid integration of GFET arrays and read-out ICs. In order to avoid artifacts, the proposal does not employ any switch in the GFET array and it is insensitive to the flicker noise of the CMOS frontend. A modular read-out IC architecture targeting the continuous acquisition of up to 1024 μECoG channels is introduced together with a collection of low-power CMOS circuits for the practical implementation of each building block. A test chip of the proposed system is currently being integrated in 0.18-μm 6-metal CMOS technology

De lo m?s lindo y de lo m?s pobre: Transnational Borges and Sandra Cisneros
No full textThis dissertation examines the influence of Argentine writer Jorge Luis Borges on the writings of twenty-first century Mexican American author Sandra Cisneros, as well as how reading her work helps us better understand overlooked elements of his writings, including marginality, gender roles, sexuality and the rights to self-definition, agency and self-expression of women and women writers. Though Cisneros is one of the most popular women writers in the United States, the first Chicana writer to be published by a major New York publishing house and an important influence for a new generation of writers, she has been dismissed by many critics as not a serious writer, or primarily a testimonial writer. By linking her writing with Borges, I present her as a United States descendent of the Latin American literary tradition that gained worldwide acclaim during the so-called Latin American literary boom of the 1960s. This dissertation departs from representations of Cisneros as solely a Chicana writer linking her instead to a north-south transnational, transborder literary tradition. As we shall see in this dissertation, for decades Borges has been a literary companion at Cisneros’s side. From Cisneros’s interviews, we know that she had first read Borges beginning in high school in the late 1960s; her most recent publication, a collection of essays entitled A House of My Own (2015) features references to Borges as a major influence on her work. In a 2015 interview, Cisneros said that Borges “me dio permiso para combinar mitos y sue?os y cuentos de hadas en mis cuentos.” T.S. Eliot, speaking on literary relationships across time in “Tradition and the Individual Talent,” asserts, “the past should be altered by the present as much as the present is directed by the past” (Sacred Wood 50). This dissertation will also examine how reading Cisneros—both her fictions and essays in which she directly references her readings of Borges’s work—in turn alters the way we read Borges. Additionally, it considers how themes raised in this early twentieth-century Argentine male writer’s work develop and change in Cisneros’s late twentieth and early twenty-first century Mexican American female imagination. These themes include gender role reversal during the advent of feminism and the emergence of women in the workplace in the twentieth century; popular and marginalized cultures; personal and collective identities; cultural hybridity and bilingualism. This dissertation is comprised of four thematic comparative chapters that contribute to new understandings of both Borges and Cisneros. CHAPTER ONE begins the dissertation with the influence of the poetry and prose in Borges’s Dreamtigers (1964) on Cisneros’s highly acclaimed The House on Mango Street (1984). CHAPTER TWO has an urban studies focus through the literary representations of two Latin American capitals, Buenos Aires in Borges’s “Fundaci?n m?tica de Buenos Aires” (1923) and Mexico City in Cisneros’s Caramelo (2002). CHAPTER THREE is a reconsideration of Borges’s female-centered writings, including his translations of Virginia Woolf’s Orlando (1928) and A Room of One’s Own (1929), through Sandra Cisneros’s writings and feminism. CHAPTER FOUR assesses elements of Buddhist spirituality in Cisneros’s twenty-first century writings gained in part through Borges’s writings on Buddhism near the end of his life. The dissertation will demonstrate that Borges remains Cisneros’s most important literary maestro with his influence felt in her poetry, fiction, and essays from adolescence in the 1960s through her recent A House of My Own (2015)
