Role of quark-quark correlation in baryon structure and non-leptonic weak transitions of hyperons
We study the role of quark-quark correlation in the baryon structure and, in
particular, the hyperon non-leptonic weak decay, which is sensitive to the
correlation between quarks in the spin-0 channel. We rigorously solve
non-relativistic three-body problem for SU(3) ground state baryons to take into
account the quark-pair correlation explicitly. With the suitable attraction in
the spin-0 channel, resulting static baryon properties as well as the parity
conserving weak decay amplitudes agree with the experimental values. Special
emphasis is placed also on the effect of the SU(6) spin-flavor symmetry
breaking on the baryon structure. Although the SU(6) breaking effects on the
local behavior of the quark wave functions are considerable due to the spin-0
attraction, the calculated magnetic moments are almost the same as the naive
SU(6) expectations
Glycemic control in a 79-year-old female with mild cognitive impairment using a medication reminder device: a case report
A 79-year-old female with type 2 diabetes and mild cognitive impairment (Clinical Dementia Rating score of 0.5) was supported with medication with regard to the daily requirements using a medication reminder device. Use of this device not only improved her medication adherence, hemoglobin A1c level, and self-confidence but also reduced caregiver's burden. For elderly patients with such diseases, loading the device with medication, providing advance notice before mechanical reminders for a short period after the device's activation, monitoring unused medication, and adjusting the timing of reminders according to users' daily routine, seemed to facilitate daily use of the device.ArticleINTERNATIONAL PSYCHOGERIATRICS. 26(6):1045-1048 (2014)journal articl
Phonon density of states and compression behavior in iron sulfide under pressure
We report the partial phonon densities of states (DOS) of iron sulfide, a possible component of the rocky planet's core, measured by the Fe-57 nuclear resonant inelastic x-ray scattering and calculate the total phonon DOS under pressure. From the phonon DOS, we drive thermodynamic parameters. A comparison of the observed and estimated compressibilities makes it clear that there is a large pure electronic contribution in the observed compressibility in the metallic state. Our results present the observation of thermodynamic parameters of iron sulfide with the low-spin state of an Fe2+ ion at the high density, which is similar to the condition of the Martian core

Constituent quark model for baryons with strong quark-pair correlations and non-leptonic weak transitions of hyperon
We study the roles of quark-pair correlations for baryon properties, in
particular on non-leptonic weak decay of hyperons. We construct the quark wave
function of baryons by solving the three body problem explicitly with
confinement force and the short range attraction for a pair of quarks with
their total spin being 0. We show that the existence of the strong quark-quark
correlations enhances the non-leptonic transition amplitudes which is
consistent with the data, while the baryon masses and radii are kept to the
experiment.Comment: 4 pages, 2 figures, talk presented at KEK-Tanashi International
