We derive the explicit three-body contact potential for a dilute condensed Bose gas from microscopic theory. The three-body coupling constant exhibits the general form predicted by Wu [Phys. Rev. 115, 1390 (1959)]] and is determined in terms of the amplitudes of two- and three-body collisions in vacuum. In the present form, the coupling constant becomes accessible to quantitative studies which ...

BACKGROUND Assessing the impact of cost sharing on healthcare utilization is a critical issue in health economics and health policy. It may affect the utilization of different services, but is yet to be well understood. OBJECTIVE This paper investigates the effects of reducing cost sharing for outpatient services on hospital admissions by exploring a subsidy policy for children's outpatient s...

The ability of force fields to reproduce relative conformational energies for seven molecules is probed. The correlation against LMP2/cc-pVTZ results for standard force field employing fixed partial charges deteriorates as the molecules become more polar. Inclusion of multipole moments and intramolecular polarization can improve the correlation, and both contributions are of similar importance....

Cathodoluminescence and photoluminescence of Bi12SiO20 and Bi12GeO20 samples are studied. Both kinds of samples show a dark orange central part or core. Emissions in the blue, green, and red spectral regions are observed. The 640 nm band is the predominant feature in the core emission. The evolution of this band during electron irradiation suggests possible emission mechanisms. In addition, two...

We describe a new species, Epipedobates darwinwallacei sp. nov., from the area of Mindo, on northwestern Ecuador. It inhabits low montane forests in an elevational range of about 1250-1390 m. It differs from all congeneric species by its strong aposematic coloration and tarsal keels. Among species of Epipedobates, the new species has been confused with E. boulengeri and E. espinosai, but it dif...
