The non-relativistic quark model has been a useful tool in the study of hadrons. Baryons and mesons are described by quantum mechanical wavefunctions for nonrelativistic constituent quarks. The lowest lying baryons, the 81/2 and 103/2, are three quark states with wavefunctions which are completely antisymmetric in color, and completely symmetric in position and spin-flavor. The properties of ba...

We present a program that allows for the computation of tensor products of irreducible representations of Lie algebras A−G based on the explicit construction of weight states. This straightforward approach (which is slower and more memoryconsumptive than the standard methods to just calculate dimensions of the tensor product decomposition) produces Clebsch-Gordan coefficients that are of intere...

After careful introduction and discussion of the concepts involved, procedures are developed to compute Racah and Clebsch-Gordan coefficients for general r-fold tensor products of the U(N) groups. In the process, the multiplicity of a given irreducible representation (irrep) in the direct sum basis is computed, and generalized Casimir operators are introduced to uniquely label the multiple irre...

We study the tensor category of modules over a semisimple bialgebra H under the assumption that irreducible H -modules of the same dimension >1 are isomorphic. We consider properties of Clebsch–Gordan coefficients showing multiplicities of occurrences of each irreducible H -module in a tensor product of irreducible ones. It is shown that, in general, these coefficients cannot have small values....

BACKGROUND Because of the problem of elbow and shoulder injuries in baseball pitchers between 9 and 14 years of age, the USA Baseball Medical & Safety Advisory Committee and the Department of Recreation and Sports in Puerto Rico developed injury prevention guidelines for pitchers. The purpose of this study was to determine the compliance of pitching coaches of 9- to 14-year-old Little League te...

Clinical trials investigating the effects of soy food intake require high compliance with a dietary protocol. Measuring soy isoflavonoids in bodily fluids is the most objective method currently available in determining compliance to a soy diet. In the present study, we investigated how frequently the urinary isoflavonoid excretion rate (UIER) should be analyzed to provide a reasonably accurate ...

This paper examines the effects of risk aversion on compliance choices in markets for pollution control. A firm's decision to be compliant or not is independent of its manager's risk preference. However, non-compliant firms with risk-averse managers will have lower violations than otherwise identical firms with risk-neutral managers. The violations of non-compliant firms with risk-averse manage...

This paper uses the unique Taxpayer Compliance Measurement Program (TCMP) micro data to study the equity effects of noncompliance. We access four years of TCMP data, 1979, 1982, 1985, and 1988. The TCMP data allows us to observe income and taxes before and after a tax audit. In order to generate a range of scalar estimates of the redistributive impact of more complete compliance we employ the f...

trinidad is a small island developing state caught between the need to engage rapid development while respecting and preserving the environment. this study assessed citizens' education needs related to the environmental laws of trinidad and tobago. it focused on a densely populated, at- risk area of the country referred to as the east-west (e-w) corridor. two hundred (200) persons living along ...

The usefulness of measuring respiratory flow in the airway and at the chest wall and of measuring respiratory input impedance (Z) to monitor high frequency ventilation was investigated by computer simulation using a monoalveolar 10-coefficient model. The latter included a central airway with its resistance (Rc) and inertance (lc), a resistive peripheral airway (Rp), a lumped bronchial complianc...
