MFO-RIMS Tandem Workshop: Symmetries on Polynomial Ideals and Varieties (hybrid meeting)
No full textThe study of symmetry as a structural property of algebraic objects is one of the fundamental pillows of the developments of modern mathematics, most prominently beginning with the work of Abel and Galois. The focus of the workshop was on permutation actions of the symmetric group on polynomial rings and algebraic and semi-algebraic sets. More concretely, it was centered around recent developments in the asymptotic setup of symmetric ideals in the polynomial ring in infinitely many variables
A successful model of regional healthcare information exchange in Japan: Case Study in Kagawa Prefecture
No full textIn this study, we focused on analysis of healthcare data exchange over the network. For the advance of broadband capability development, many governments expect online medical information exchange between medical institutions. Japanese government also has tried to deploy ICT in the healthcare field. In Japan, many healthcare ICT projects started, but almost of all the projects face many issues and failed to continue. This situation caused us to clarify the success factor of healthcare information exchange network. For inspecting the success factors, we analyzed information access of healthcare systems in Kagawa prefecture of Japan. Kagawa prefecture is one of the most advance areas for healthcare information technology. We analyzed four medical ICT projects in Kagawa prefecture: K-MIX, Critical Pathway for Diabetes, E-prescription, and PHR. In addition, we inspected characteristics of exchanged data in the network, and stakeholder involved in these projects. This analysis lets us find various types of healthcare ICT projects. Characteristic of data processed in the projects caused differences of characteristic of the projects. On the other hand, multiple systems process same data, though the project does not share the data itself. Considering various types of medical information exchanges projects, we propose classification and standard format of exchanged data according to their characteristic are critical for efficient business deployment. --e-Health,regional healthcare information exchange,EHR
Analysis for science librarians of the 2015 Nobel Prize in Physiology or Medicine: the life and work of William C. Campbell, Satoshi Ōmura, and Youyou Tu
No full textParasites affect humans worldwide with varying degrees of seriousness. Some of the most impactful parasitic infections affect millions of people, many of whom are already impoverished and struggling. The discoveries of the 2015 Nobel Laureates in Physiology of Medicine have changed the way some of these serious parasitic infections are treated, saving and improving the lives of countless people. These Laureates are William C. Campbell, Satoshi Ōmura, and Youyou Tu
Algebraic shifting of cyclic polytopes and stacked polytopes
No full textAbstractGil Kalai introduced the shifting-theoretic upper bound relation as a method to generalize the g-theorem for simplicial spheres by using algebraic shifting. We will study the connection between the shifting-theoretic upper bound relation and combinatorial shifting. Also, we will compute the exterior algebraic shifted complex of the boundary complex of the cyclic d-polytope as well as of a stacked d-polytope. It will turn out that, in both cases, the exterior algebraic shifted complex coincides with the symmetric algebraic shifted complex
Algebraic shifting and strongly edge decomposable complexes
No full textLet be a simplicial complex with vertices, and let be either its exterior algebraic shifted complex or its symmetric algebraic shifted complex. If is a simplicial sphere, then it is known that (a) is pure and (b) -vector of is symmetric. Kalai and Sarkaria conjectured that if is a simplicial sphere then its algebraic shifting also satisfies (c) , where is the boundary complex of the cyclic -polytope with vertices. We show this conjecture for strongly edge decomposable spheres introduced by Nevo. We also show that any shifted simplicial complex satisfying (a), (b) and (c) is the algebraic shifted complex of some simplicial sphere
