Node Query Preservation for Deterministic Linear Top-Down Tree Transducers

This paper discusses the decidability of node query preservation problems for XML document transformations. We assume a transformation given by a deterministic linear top-down data tree transducer (abbreviated as DLT^V) and an n-ary query based on runs of a tree automaton. We say that a DLT^V Tr strongly preserves a query Q if there is a query Q' such that for every document t, the answer set of Q' for Tr(t) is equal to the answer set of Q for t. Also we say that Tr weakly preserves Q if there is a query Q' such that for every t_d in the range of Tr, the answer set of Q' for t_d is equal to the union of the answer set of Q for t such that t_d = Tr(t). We show that the weak preservation problem is coNP-complete and the strong preservation problem is in 2-EXPTIME.Comment: In Proceedings TTATT 2013, arXiv:1311.505

Brane Configuration from Monopole Solution in Non-Commutative Super Yang-Mills Theory

We study the structure of the monopole configuration in U(2) non-commutative super Yang-Mills theory. Our analysis consists of two steps: solving the BPS equation and then the eigenvalue equation in the non-commutative space. Calculation to the first non-trivial order in the non-commutativity parameter theta shows that the monopole exhibits a certain non-locality. This structure is precisely the one expected from the recent predictions by the brane-configuration technique.Comment: 12 pages, LaTeX, 2 eps figures, v2: gauge invariance problem clarified, v3: final version to be published in JHE

Structural Development Studies of Subtype-Selective Ligands for Peroxisome Proliferator-Activated Receptors (PPARs) Based on the 3,4-Disubstituted Phenylpropanoic Acid Scaffold as a Versatile Template

Improvements in our understanding of the functions of the nuclear receptor peroxisome proliferator-activated receptor (PPAR) subtypes as pleiotropic regulators of biological responses, including lipid, lipoprotein, glucose homeostasis, inflammation, differentiation and proliferation of various cancer cells, and memory, have provided an opportunity to develop novel PPAR ligands with characteristic subtype selectivity. Such ligands are not only chemical tools to investigate the functions of PPARs, but also candidates for the treatment of PPAR-mediated diseases, including metabolic syndrome, inflammation, dementia, and cancer. This minireview summarizes our work on the design, synthesis, and pharmacological evaluation of subtype-selective PPAR agonists based on the use of 3,4-disubstituted phenylpropanoic acid as a versatile template

Moore's Law, Increasing Complexity, and the Limits of Organization: The Modern Significance of Japanese Chipmakers' DRAM Business

The purpose of this paper is to identify the organizational constraints on science innovations in the midst of the increasing complexity of technology and markets and to search for measures to overcome them. For this purpose, we scrutinize the rise and fall of Japanese chipmakers in their commodity DRAM business during the last three decades, during which time all of them have been deeply wounded. We take up this business case mainly because the Japanese semiconductor industry seems to be a forerunner of various science-based industries facing rapid globalization and could provide instructive examples for them in an age of speed-to-market. We think that the rise and fall of Japanese chipmakers in their commodity DRAM business has been deeply influenced by three kinds of ever-growing complexities: the growing market-complexity triggered by the collapse of commodity DRAM prices in 1996, the growing (manufacturing) system-complexity boosted by the advent of 200mm fabrication plants (fabs) in the early 1990s, and the growing process-complexity in fabrication technologies necessitated by 64Mb commodity DRAMs. We explain how and why, compared with U.S. and Korean competitors, Japanese chipmakers could not respond to these growing complexities in a systematic and well-organized manner.

Réinventer les arts performatifs folkloriques

Au Japon, les « arts performatifs folkloriques » ont connu des transformations importantes à mesure que s’est diversifiée leur gestion administrative. Aujourd’hui, ces arts reçoivent un soutien soit au titre de « patrimoine culturel folklorique immatériel », soit à celui de « ressource touristique ». Dans le premier cas, ils sont préservés et mis en valeur dans le cadre de la loi sur la protection du patrimoine culturel ; dans le second, ils entrent dans le champ de la loi relative à la promotion du tourisme, des commerces et industries régionaux. Or les principes fondateurs de ces deux lois ont généralement été considérés comme contradictoires, voire antagonistes. L’imbriquement de ces deux logiques influe pourtant sur les conditions locales de conservation des spectacles folkloriques, et, plus encore, génèrent de nouvelles formes culturelles. L’article qui suit s’intéresse à l’impact des mesures administratives sur la réinvention des spectacles folkloriques, et examine comment il est possible, en conséquence, de repenser ces derniers.In Japan the various forms of entertainment known as the folk performing arts are undergoing great change as the policies for administering them diversify. Today folk performing arts are treated within two social contexts: as traditional and regional culture to be preserved and practically managed in accordance with the provisions of the Cultural Properties Protection Law; and as tourist resources covered by the law concerning the revitalization of tourism and selected regional commerce and industry. The basic principles underlying these two laws have generally been thought to be in conflict with one another. However, the intermingling of these two social contexts not only influences the local conditions within which folk performing arts exist, but also enables the birth of new cultural forms. In this paper I will examine how folk performing arts are being re-created through the diversification of administrative processes, and consider how we can, in fact, re-imagine folk performing arts
