Kawai Hayao y el Círculo Eranos
No full textPonencia presentada en el I Congreso Internacional, X Nacional de la Asociación de Estudios Japoneses en España, Universidad de Valladolid.Recientemente la figura de Kawai Hayao (1928-2007), prestigioso psiquiatra japonés de la escuela junguiana a la vez que uno de los representantes culturales del Japón del cambio de siglo, está siendo reivindicada en Japón, de lo cual es muestra el volumen homenaje aparecido en 2009 bajo el título de Shisōka: Kawai Hayao, publicado por la editorial Iwanami bajo la coordinación de Nakazawa Shin’ichi (1950) y el hijo de Hayao, Kawai Toshio (1957). La carrera académica de Kawai se centra entre 1972-1992, en que ejerció como Decano de la Facultad de Educación en su Universidad de origen. Podemos argumentar que igual que los artistas y artesanos japoneses han mostrado su “pensamiento” a través de sus obras, idea ya presente en H. Nakamura (1912-1999), como interpreta Sh. Nakazawa (1950), el pensamiento de Kawai no se puede expresar de manera lógica según categorías lingüísticas, sino que siendo su objeto el material de nuestro inconsciente, se expresa de manera meta-lingüística y meta-racional, asumiendo las contradicciones del yo, tal como expone en Buddhism and the Art of Psychotherapy. Todo ello tiene que ver con la estética de la cerámica Muromachi, Rikyū y Oribe. El objeto elude el acabamiento, la perfección. La figura de Hiruko introduce la importancia de lo espúreo, lo inútil, lo inarticulado, el fracaso como parte de la estructura de la mente. Ello es porque el inconsciente es inclusivo, frente a la estructura consciente que es selectiva y segregacionista. De este modo Kawai se nos dibuja como un pensador genuino, pero según el modelo del artista o artesano, experto en el arte del pensar, o lo que es lo mismo en pensar como un arte

Almost formality of manifolds of low dimension
No full textIn this paper we introduce the notion of Poincaré DGCAs of Hodge
type, which is a subclass of Poincaré DGCAs encompassing the de Rham algebras of closed orientable manifolds. Then we introduce the notion of the small algebra and the small quotient algebra of a Poincaré DGCA of Hodge
type. Using these concepts, we investigate the equivalence class of (r-1)-connected (r > 1) Poincaré DGCAs of Hodge type. In particular, we show that an (r-1)-connected Poincar ́e DGCA of Hodge type A* of dimension n <=
5r - 3 is A-infinity-quasi-isomorphic to an A_3-algebra and prove that the only obstruction to the formality of A* is a distinguished Harrison cohomology class [μ3] in Harr^3-1(H*(A*), H*(A*)). Moreover, the cohomology class [μ3] and
the DGCA isomorphism class of H*(A*) determine the A-infinity-quasi-isomorphism
class of A*. This can be seen as a Harrison cohomology version of the Crowley-
Nordstrom results on rational homotopy type of (r - 1)-connected (r > 1)
closed manifolds of dimension up to 5r -3. We also derive the almost formality of
closed G2 -manifolds, which have been discovered recently by Chan-Karigiannis-
Tsang, from our results and the Cheeger-Gromoll splitting theorem

The species is similar to M. rydalensis (Edwards), but in M. rydalensis the superior volsella has three basal setae, whereas M. truncatus has a group of more than three setae on the basal tubercle. Furthermore, the apex of the anal point is pointed in M. rydalensis but truncated in M. truncatus. The specimen from Yunnan Province was misidentified and listed as M. rydalensis (Edwards) by Wang (2000).Published as part of Qi, Xin & Wang, Xinhua, 2006, A review of Microtendipes Kieffer from China (Diptera: Chironomidae), pp. 37-51 in Zootaxa 1108 on page 43, DOI: 10.5281/zenodo.17149
Visualizing the Marrow of Science
No full textThis study proposes a new methodology that allows for
the generation of scientograms of major scientific domains,
constructed on the basis of cocitation of Institute
of Scientific Information categories, and pruned using
PathfinderNetwork, with a layout determined by algorithms
of the spring-embedder type (Kamada–Kawai),
then corroborated structurally by factor analysis. We
present the complete scientogram of the world for the
Year 2002. It integrates the natural sciences, the social
sciences, and arts and humanities. Its basic structure
and the essential relationships therein are revealed,
allowing us to simultaneously analyze the macrostructure,
microstructure, and marrow of worldwide scientific
output

Chironomus ginzanabeus Sasa et Suzuki, 2001a: 9. syn. n. Chironomus inabeceus Sasa, Kitami et Suzuki, 2001; 3. syn. n. Specimens examined: Japan: Toyama Pref., Family Park, holotype ♂ of Chironomus famiabeus, 23. vi. 1993, M. Sasa [specimen No. 253:01 (NSMT-I-Dip-4931)]; Hokkaido, Mt. Ginzan, holotype ♂ of Chironomus ginzanabeus, 1. ix. 2000, H. Suzuki [specimen No. 403:013 (NSMT-I-Dip 5 383)]; Fukushima Pref., Lake Inawashiro, holotype ♂ of Chironomus inabeceus, 17. viii. 2000, K. Kitami [specimen No. 401:90 (NSNT-I-Dip-5377)]. In their original description of Chironomus inabeceus, Sasa et al. (2001) pointed out that the wing is entirely clothed in macrotrichia. However, we could not recognize this feature in the holotype. The shape of the anal point, superior and inferior volsellae support that C. famiabeus, C. ginzanabeus and C. inaabeus are junior synonyms of Glyptotendipes biwasecundus.Published as part of Yamamoto, Nao & Yamamoto, Masaru, 2018, Taxonomic information on some Japanese Chironomidae (Diptera) described by Dr. M.

Worldsheet analysis of gauge/gravity dualities
No full textGauge/gravity dualities are investigated from the worldsheet point of view. In [H. Kawai, T. Suyama, AdS/CFT correspondence as a consequence of scale invariance, Nucl. Phys. B 789 (2008) 209, arXiv:0706.1163 [hep-th]; H. Kawai, T. Suyama, Some implications of perturbative approach to AdS/CFT correspondence, Nucl. Phys. B 794 (2008) 1, arXiv:0708.2463 [hep-th]], a duality between 4d SYM and supergravity on
has been partly explained by using an anisotropic scale invariance of worldsheet theory. In this paper, we refine the argument and generalize it to lower dimensional cases. We show the correspondence between the Wilson loops in
-d SYM and the minimal surface in the black p-brane background. Although the scale invariance does not exist in these cases, the generalized scale transformation can be utilized. We also find that the energy density of open strings can be related to the ADM mass of the p-brane without relying on this symmetry
