Brane induced gravity from asymmetric warped compactification

We show that brane induced gravity can be realized as a low energy effective theory of brane worlds with asymmetric warped compactification. A self-accelerating universe without cosmological constant on the brane can be realized in a model where one side of the bulk has finite volume, but the other side has infinite volume. The spin-2 perturbations for brane induced gravity and asymmetric warped compactification models have the same spectrum at low energies. For a de Sitter brane, the spin-2 graviton has mass in the range $0<m^2 \leq 2H^2$, with $m^2=2H^2$ in the self-accelerating universe.Comment: 4 pages, 3 figures, typos corrected, a reference adde

Vacuum Wave Functional of Pure Yang-Mills Theory and Dimensional Reduction

Working in a Hamiltonian formulation with $A_0 = 0$ gauge and also in a path integral formulation, we show that the vacuum wave functional of four-dimensional pure Yang-Mills theory has the form of the exponential of a {\it three}-dimensional Yang-Mills action. This result implies that vacuum expectation values can be calculated in Yang-Mills theory but one dimension lower. Our analysis reveals that this dimensional reduction results from a stochastic nature of the theory.Comment: 11 pages, LaTeX fil

El concepto de la flor en la literatura japonesa

Este artículo analiza el concepto de hana (la flor) en la cultura japonesa y, en particular, en la literatura japonesa. El ancestral fenómeno de contemplar el cerezo en flor (hanami) y el arte tradicional de arreglar las flores (ikebana) son ejemplos que reflejan la atención especial que otorga el pueblo japonés a las flores. La literatura japonesa recoge en toda su extensión este amor a la naturaleza de los japoneses hasta crear una filosofía singular sobre el concepto de la florThis article presents an analysis of the concept of hana (the flower) in Japanese culture and, particularly, in the Japanese literature. The ancient phenomenon of contemplating the cherry blossoms (hanami) and the traditional art of flower arrangement (ikebana) are examples that reflect well the special consideration rendered to the flowers by Japanese people. The Japanese literature brings together in all its extension this love for the nature of the Japanese, to the extent of creating a singular philosophy about the concept of the flowe

The Interpreter, the Monitor and the Language Arbiter

The trustworthiness of translators and interpreters has long been an issue in the profession. In some cases, a set of procedures are established to ensure the trust of clients and end-users. In the International Military Tribunal for the Far East (1946-1948), such procedures took on remarkable form. During the trial, three ethnically and socially different groups of language personnel engaged in three different functions within the overall interpreting process: Japanese nationals as interpreters, Japanese Americans as monitors, and U.S. military officers as language arbiters who ruled on the disputed interpretations. Sociopolitical aspects such as trust, power and control are evident in this hierarchical structure. In such political settings, and in others seen today, the trustworthiness of the interpreter may override the quality of interpreting.La question de la confiance à accorder aux traducteurs et aux interprètes est débattue depuis longtemps dans la profession. Dans certains cas, un ensemble de procédures sont établies afin de susciter la confiance des clients et des utilisateurs. Au sein du Tribunal militaire pour l’Extrême-Orient (1946-1948), ces procédures ont pris une forme particulière. Pendant le procès, trois groupes différents sur les plans social et ethnique assumaient trois fonctions différentes dans le cadre du processus global d’interprétation : les Japonais interprétaient, les Américains d’origine japonaise contrôlaient, et les officiers militaires américains jouaient le rôle d’« arbitres » linguistiques qui tranchaient en cas de controverse. Les aspects sociopolitiques tels que la confiance, le pouvoir et le contrôle sont évidents dans cette structure hiérarchique. Dans de tels environnements politiques ainsi que dans d’autres que nous connaissons aujourd’hui, le besoin de faire confiance à l’interprète peut prendre le pas sur la qualité de l’interprétation
