The Constancy of the Constants of Nature: Updates
Takeshi Chiba
The current observational and experimental bounds on the time variation of the constants of nature (the fine structure constant , the gravitational constant and the proton-e…
Explicit formula of the separability criterion for continuous variables systems
Kazuo Fujikawa
A very explicit analytic formula of the separability criterion of two-party Gaussian systems is given. This formula is compared to the past formulation of the separability criterio…
Two-Baryon Potentials and H-Dibaryon from 3-flavor Lattice QCD Simulations
Takashi Inoue, Sinya Aoki, Takumi Doi +6
Baryon-baryon potentials are obtained from 3-flavor QCD simulations with the lattice volume L ~ 4 fm, the lattice spacing a ~ 0.12 fm, and the pseudo-scalar-meson mass M_ps =469 -…
Symmetries on almost symmetric numerical semigroups
Hirokatsu Nari
The notion of almost symmetric numerical semigroup was given by V. Barucci and R. Fröberg. We characterize almost symmetric numerical semigroups by symmetry of pseudo-Frobenius num…
On the semicontinuity problem of fibers and global -regularity
Kazuma Shimomoto
In this article, we discuss the semicontinuity problem of certain properties on fibers for a morphism of schemes. One aspect of this problem is local. Namely, we consider propertie…
Coupled Oscillator Model of the Business Cycle with Fluctuating Goods Markets
Y. Ikeda, H. Aoyama, Y. Fujiwara +4
The sectoral synchronization observed for the Japanese business cycle in the Indices of Industrial Production data is an example of synchronization. The stability of this synchroni…
