A quasispin tensor decomposition of the two-nucleon interaction determines the most general seniorityconserving rotationally invariant two-body interaction in a j shell. Such interactions define solvable and partially solvable shell model Hamiltonians for which the unitary symplectic algebra USp(2 j11) provides a complete set of quantum numbers for a subset of states. The matrix elements of sen...

BACKGROUND The purpose of the present study was to assess the vision-related quality of life (QOL) of visually impaired patients using the Japanese 11-item National Eye Institute Visual Function Questionnaire (VFQ-J11). Comparisons with the 25-item version (VFQ-25) and the EuroQoL Index using a large group of patients with various degrees of impairments and various causative diseases were perfo...

The molecular beam electric resonance technique has been used to examine the hyperfine spectrum of CsF to determine the nuclear quadrupole interaction of the cesium nucleus. A total of 95 transitions in vibrational states v5025 and rotational states J5128 have been included in a fit to determine the cesium nuclear quadrupole and spin–rotation interactions, the fluorine spin–rotation interaction...

PURPOSE To evaluate the relationship between vision-related quality of life (QOL) as measured by the short-form 11-item Japanese version of the Visual Function Questionnaire (VFQ-J11) and the severity of visual field (VF) defects in patients with glaucoma. METHODS The study included 134 glaucoma patients and 30 normal subjects. VF testing using the Humphrey Field Analyzer was performed to obt...

Population aging is expected to slow US economic growth. We use variation in the predetermined component of population across states estimate impact on growth GDP per capita for 1980–2010. find that each 10 percent increase fraction age 60+ decreased by 5.5 percent. One-third reduction arose from slower employment growth; two-thirds due labor productivity Labor compensation and wages also decli...

This paper offers projections of future transmission dynamics for SARS-CoV-2 in an SEIRS model with demographics and waning immunity. In a stylized optimal control setting calibrated to the United States, we show that disease is endemic steady state its are characterized by damped oscillations. The magnitude oscillations depends on how fast immunity wanes. social distancing policy both curbs pe...

We quantify the role of population aging in structural transformation process. Household-level data from United States show that fraction expenditures devoted to services increases with household age. use a shift-share decomposition and quantitative model US accounted for about fifth observed increase service share consumption between 1982 2016. The contribution rise is same size as real income...

We consider a stochastic environment to study interactions among pollution growth, demographic changes, and economic growth. Drawing on the empirical findings of slow convergence patterns of pollution shocks (viz., with a long-memory), we build an analytical framework where stochastic environmental feedback effects on population changes are reflected upon aggregate economic growth. Long-memory ...
