Z_{12-I} Orbifold Compactification toward SUSY Standard Model
We explain the orbifold compactification in string models and present a
Z_{12-I} orbifold compactification toward supersymmetric standard models. We
also point out an effective R-parity from this string construction. The VEVs of
gauge singlets are chosen such that phenomenological constraints are satisfied.Comment: 13 pages with 5 figure. Talk presented at "CTP Symposium on SUSY at

Uniqueness of convex ancient solutions to mean curvature flow in higher dimensions
In this paper, we consider noncompact ancient solutions to the mean curvature
flow in () which are strictly convex, uniformly
two-convex, and noncollapsed. We prove that such an ancient solution is a
rotationally symmetric translating soliton.Comment: In this paper, we extend the result in arxiv:1711.00823 to higher
dimensions, assuming uniform two-convexit
Paradigm Innovation through the Strategic Collaboration between TORAY & UNIQLO : Evolution of A New Fast Fashion Business Model
The key purpose of this study is to examine the remarkable context within the evolution of the paradigm innovation in fashion product development, in the case of Japanese fashion apparel, UNIQLO, created by Fast Retailing Corp in 1998. The key theme hereby concerns innovation, and this perspective surely necessitates Fast Retailing's strategic collaboration with a Japanese new material and artificial textile powerhouse, TORAY: as TORAY's technological provision was an essential source for the dynamic product and process innovation behind the extraordinary growth of UNIQLO. Furthermore, the technological superiority also entailed its innovative positioning in market competition. It is crucial to examine how and why the two brought about their core competences together through new combinations of concepts. This should impart a few promising research perspectives regarding their innovative model of unchallenged value creation, strong market competitiveness, and sustainable corporate growth.Paradigm Innovation, Product Development, Business Model, Japanese Apparel Industry, Fashion Apparel, Fast Fashion, Fast Retailing, UNIQLO, TORAY, Alliance, Virtual Vertical Integration
On sums of three squares
Let be the number of representations of a positive integer as a
sum of three squares of integers. We give two distinct proofs of a conjecture
of Wagon concerning the asymptotic value of the mean square of .Comment: 11 pages, minor revisions made; to appear in Internat. J. Number

Supersymmetric three family chiral SU(6) grand unification model from F-theory
We obtain a supersymmetric three family chiral SU(6) grand unification model
with the global family symmetry SU(3)[family] from F-theory. This model has
nice features such as all the fermion masses are reasonably generated and there
results only one pair of Higgs doublets, realizing the doublet-triplet
splitting from the family symmetry SU(3)[family]. The proton hexality is
realized toward the proton stability problem. There is a room to fit the three
gauge couplings using the F-theory flux idea and we obtain the proton lifetime
in the 10^{36-37} yr region.Comment: 5 pages, to be published in Phys. Rev.
