On the κ\kappa-Dirac Oscillator revisited

This Letter is based on the $\kappa$-Dirac equation, derived from the $\kappa$-Poincar\'{e}-Hopf algebra. It is shown that the $\kappa$-Dirac equation preserves parity while breaks charge conjugation and time reversal symmetries. Introducing the Dirac oscillator prescription, $\mathbf{p}\to\mathbf{p}-im\omega\beta\mathbf{r}$, in the $\kappa$-Dirac equation, one obtains the $\kappa$-Dirac oscillator. Using a decomposition in terms of spin angular functions, one achieves the deformed radial equations, with the associated deformed energy eigenvalues and eigenfunctions. The deformation parameter breaks the infinite degeneracy of the Dirac oscillator. In the case where $\varepsilon=0$, one recovers the energy eigenvalues and eigenfunctions of the Dirac oscillator.Comment: 5 pages, no figures, accepted for publication in Physics Letters

Health benefits and uncertainty: an experimental analysis of the effects of risk presentation on auction bids for a healthful product

Experimental subjects receive a different presentation of a food product's potential health risk reductions if eaten regularly. They are then asked to bid for the product. Results suggest that the bids vary across the groups that receive differing risk information.

Health Benefits and Uncertainty: An Experimental Analysis of the Effects of Risk Presentation on Auction Bids for a Healthful Product

Experimental subjects receive a different presentation of a food product's potential health risk reductions if people habitually eat it, and then asked to bid for the product. Results suggest that the bids vary across the groups that receive differing risk information.Health risks, experimental economics, auctions, uncertainty, Risk and Uncertainty, D81, I12,

The Effect of Risk Presentation on Product Valuation: An Experimental Analysis

We examine how people might evaluate a product with novel attribute, given various kinds of risk information. Using a product with healthful benefits, we assess subjects' willingness to pay given various kinds of health risk information conveying reduced health risks, life tradeoffs, and ambiguity. Four treatments in separate non-hypothetical experimental auctions are used to elicit willingness to pay values. Results suggest that willingness to pay vary across the groups that receive differing risk information. Specifically, willingness to pay was higher for the group that was given clear risk information and questions related to life tradeoffs than for the group given ambiguous risk information. Willingness to pay was lowest for the group that was given no risk information at all.Risk and Uncertainty,

New Algorithms for Computing a Single Component of the Discrete Fourier Transform

This paper introduces the theory and hardware implementation of two new algorithms for computing a single component of the discrete Fourier transform. In terms of multiplicative complexity, both algorithms are more efficient, in general, than the well known Goertzel Algorithm.Comment: 4 pages, 3 figures, 1 table.
