We study the effect of global-symmetry violating higher-dimension operators induced by Planck-...

The discovery of new ideas is the engine of growth in many recent growth models. As emphasized by Paul Romer (1986, 1990), ideas are different from most goods analyzed in economics in that they are nonrivalrous: the use of an idea by one person does not preclude, at a technological level, the simultaneous use of the idea by another person, or even by many people. This leads to a tight link betw...

We study the phenomenology and cosmology of the Majoron (flavon) models of three active and one inert neutrino paying special attention to the possible (almost) conserved generalization of the Zeldovich-Konopinski-Mahmoud lepton charge. Using Planck scale physics effects which provide the breaking of the lepton charge, we show how in this picture one can incorporate the solutions to some of the...

selective estrogen receptor modulators (serms) such as raloxifene have already shown beneficial effects on negative, positive and general psychopathology symptoms in postmenopausal women with schizophrenia. the purpose of the present investigation was to assess the efficacy of raloxifene as an adjuvant agent in the treatment of men with chronic schizophrenia in an 8-week double-blind and placeb...

the empirical bayes estimators of treatment effects in a factorial experiment were derived and their asymptotic properties were explored. it was shown that they were asymptotically optimal and the estimator of the scale parameter had a limiting gamma distribution while the estimators of the factor effects had a limiting multivariate normal distribution. a bootstrap analysis was performed to ill...
