No full textSigma models with (0, 2) supersymmetry in two dimensions possess quasi-topological sectors characterized by chiral algebras. In this thesis, we study these chiral algebras and explore their nonperturbative aspects. The chiral algebras of (0, 2) models emerge when one considers the cohomology of local operators with respect to one of the supercharges, and provide infinite-dimensional generalizations of the chiral rings of (2, 2) models. Perturbatively, they enjoy rich math-ematical structures described by sheaves of chiral differential operators. Nonperturba-tively, however, they vanish completely for certain (0, 2) models with no left-moving fermions. Examples include the models in which the target spaces are the complete flag manifolds of compact semisimple Lie groups. The vanishing of the chiral algebra of a (0, 2) model implies that supersymmetry is spontaneously broken in the model, which in turn suggests that no harmonic spinors exist on the loop space of the target space. We analyze this supersymmetry breaking using holomorphic Morse theory on the loop space in the case where the target space is CP1. As expected, we find that instantons interpolate between pairs of perturbative supersymmetric states, thereby lifting them out of the supersymmetric spectrum

Habitar el suelo. Aproximaciones estéticas hacia un habitar en relación
No full textThis text analyzes different contemporary architectural and sculptural materializations distinguishable because of the relational and contingent approach to all that surrounds us. From a sensitive approach and articulation towards what coexists, the spatial configurations exhibited here are an example of a way of doing, of an ethic and a technique, which try to inhabit this world in relation. This is perceptible in the approach and listening to the surroundings of Junya Ishigami’s architecture or in the configuration next to the things of Josu Bilbao’s floor sculpture. They are aesthetic configurations that expose, rescuing Judith Butler’s words, the irremediably relational and contingent condition of our existence. And from the manifest interdependence towards what surrounds and conditions us, these configurations are an example of what Adriana Cavarero proposes as "inclined geometry". This author understands inclination as an approach that, appearing outside itself, tends to the outside, in manifest structural interdependence of the subject towards that which coexists. This text exposes that inclined geometry through the spatial configurations of Junya Ishigami, Ryue Nishizawa, Gordon Matta-Clark and Josu Bilbao, as a possibility of inhabiting an unstable world.; Este texto analiza diferentes materializaciones arquitectónicas y escultóricas contemporáneas que se distinguen por un acercamiento relacional y contingente hacia todo aquello que nos rodea. Desde un acercamiento y articulación sensible hacia lo que coexiste, las configuraciones espaciales expuestas aquí son muestra de una manera de hacer, de una ética y una técnica, que tratan de habitar este mundo en relación. Eso es perceptible en el acercamiento y escucha hacia el entorno de la arquitectura de Junya Ishigami o en la configuración junto a las cosas de la escultura de suelo de Josu Bilbao. Son configuraciones estéticas que exponen, rescatando las palabras de Judith Butler, el carácter irremediablemente relacional y contingente de nuestra existencia. Y desde la interdependencia manifiesta hacia aquello que nos rodea y condiciona, estas configuraciones son ejemplo de lo que Adriana Cavarero propone como "geometría inclinada". Esta autora entiende por inclinación un acercarse que, asomándose fuera de sí, tiende al exterior, en manifiesta interdependencia estructural del sujeto hacia aquello con lo que coexiste. En este texto se expone esa geometría inclinada a través de las configuraciones espaciales de Junya Ishigami, Ryue Nishizawa, Gordon Matta-Clark y Josu Bilbao, como posibilidad de habitar un mundo inestable

Interactive Cognitive Modeling: Understanding and Supporting IndividualHuman Cognition
No full textCognitive modeling, approximation of human cognitive functions in a computational system, is a traditional methodologyin the field of cognitive science. Usually this methodology has been used as a tool for scientific understanding of humanmind, and evaluated by fitting to human data. In this presentation, the author proposes a framework of interactive cognitivemodeling as an application of the above methodology for understanding and supporting individual human cognition. Theframework consists of cognitive architecture, visualization of the model behavior, knowledge database of personal userand sensing devices to include the users reaction. This presentation shows two systems of interactive cognitive modelingin the field of web browsing and photo browsing
A NEW FAR INFRARED SPECTROSCOPIC METHOD USING AN InSb TUNABLE DETECTOR
No full textPresent Address: Department of Physics, The Ohio State University, Columbus, Ohio 43210.Author Institution: Low Temperature Center, Osaka University SuitaA new far infrared spectroscopic method using an InSb tunable detector---tuned by a magnetic field---is proposed. If a far infrared source, obeying the Rayleigh-Jeans relation, is used with a grating spectrometer, whose transmittance is independent of wavelength, then the detector output is proportional to for a thermal detector, to m for an InSb nontunable detector, and peaks sharply at some fixed m for a tunable detector, where m is the diffraction order. This response is illustrated by absorption spectra of water vapor measured with the tunable InSb detector for various values of the magnetic field. It is proposed to tune the spectral region of the detector synchronously with the motion of the grating, thus eliminating the need for low-frequency-pass filters
