Neural Networks as a Composition Diagnostic for Ultra-high Energy Cosmic Rays

Andre K. O. Tiba, Gustavo A. Medina-Tanco, Sergio J. Sciutto

We analyze here the possibility of studying mass composition in the Auger data sample using neural networks as a diagnostic tool. Extensive air showers were simulated using the AIR…

New Theory of Superconductivity (Part II): Confirmation at low temperature

R. Riera, J. L. Marin, R. Betancourt-Riera +1

An application of the general equation obtained in Part I to low critical temperature superconductors utilizing an "ad hoc" phononic theory is developed. Then, we arrive to a speci…

Frame Dependence of the Pair Contribution to the Pion Electromagnetic Form Factor in a Light-Front Approach

J. P. B. C. de Melo, T. Frederico, E. Pace +1

The frame dependence of the pair-term contribution to the electromagnetic form factor of the pion is studied within the Light Front approach. A symmetric ansatz for the pion Bethe-…

Low Temperature Phase Transition in Sr(0.66)Ba(0.34)Nb2O6 single Crystal Fibers

J. L. B. Faria, C. W. A. Paschoal, P. T. C. Freire +5

The structural changes in Sr(0.66)Ba(0.34)Nb2O6 single crystal fibers when the temperature decreases from 295 to 10 K is investigated by dielectric constant measurements and Raman…

A finite-dimensional representation of the quantum angular momentum operator

Rafael G. Campos, L. O. Pimentel, .

A useful finite-dimensional matrix representation of the derivative of periodic functions is obtained by using some elementary facts of trigonometric interpolation. This NxN matrix…

Radio and Far-IR Extragalactic Sources at Planck Frequencies

G. De Zotti, L. Toffolatti

We discuss the main uncertainties affecting estimates of small scale fluctuations due to extragalactic sources in the Planck Surveyor frequency bands. Conservative estimates allow…
