Three CP-violating phases of the 3 × 3 lepton flavor mixing matrix V are entangled with one another in the renormalization-group evolution from the seesaw scale (ΛSS ∼ 10 14 GeV) to the electroweak scale (ΛEW ∼ 10 2 GeV). Concerning the Dirac phase δ, we show that δ = 90 at ΛEW can be radiatively generated from δ = 0 at ΛSS in the minimal supersymmetric standard model, if three neutrino masses ...

Let α be an algebraic integer whose all conjugates lie in a sector |arg z| ≤ θ with 0 ≤ θ < 90◦. Using the method of explicit auxiliary functions, we compute the greatest lower bound v(θ) of the absolute trace of α, for θ belonging to seven subintervals of [0, 90◦). The polynomials involved in the auxiliary functions are found by Wu’s algorithm.

In order to understand the resistance of passive films formed during corrosion processes, an analytical technique using x-ray diffraction was developed to examine the structure of metal in closest proximity to the metal / liquid interface. The in-situ structure at the metal liquid interface was examined for 90 % copper and 10 % nickel (90-10 Cu-Ni) in KOH solution at room temperature and at fou...

Methane can be stored in tea clathrates, that is kinetics of methane clathrate formation can be significantly accelerated (90% saturation uptake in 20 min) by ingredients (polyphenols and saponins) in tea infusions with a volumetric capacity of up to 172 v/v.

We recently demonstrated the presence of virulence-associated protein antigen (VapA)-positive Rhodococcus equi in Jeju Island, Korea. These bacteria contained one of two distinct plasmid types, a 90-kb type II plasmid, which has been found in isolates from the native Kiso horses of Japan, and a new variant, a 90-kb type V plasmid. However, the genotypic characters of the VapA-positive R. equi f...

In 1989-90 a survey was carried out of the prevalence of snoring and related symptoms in 782 4 to 5 year old children. Two years later, in 1992, the same group of children was studied to gather information on the natural history of snoring and the related behaviour problems. A total of 507/782 (64.8%) completed questionnaires were received. Comparison of the responses with the 1989-90 survey sh...

We have used Fortran 90 to implement lattice QCD. We have designed a set of machine independent modules that define fields (gauge, fermions, scalars, etc...) and overloaded operators for all possible operations between fields, matrices and numbers. With these modules it is very simple to write high-level efficient programs for QCD simulations. To increase performances our modules also implement...
