Noise-Enhanced Transmission Efficacy of Aperiodic Signals in Nonlinear Systems

Authors: Fabing Duan, Francois Chapeau-Blondeau, Derek Abbott
Comments: 7 Pages. submitted to HotPI 2013

We study the aperiodic signal transmission in a static nonlinearity in the context of aperiodic stochastic resonance. The performance of a nonlinearity over that of the linear system is defined as the transmission efficacy. The theoretical and numerical results demonstrate that the noise-enhanced transmission efficacy effects occur for different signal strengths in various noise scenarios.

Theoretical Study of Quantization of Magnetic Flux in a Superconducting Ring

Authors: DaeHyeon Kang
Comments: 9 Pages.

We refined the concepts of electric current and fluxoid, and London’s equation that specify quantum phenomena of moving electrons and magnetic flux in a closed circuit similar to a superconducting ring, so as not to violate the uncertainty principle. On this basic the relation between the electron motion and magnetic flux in a superconductor has been theoretically investigated by means of Faraday’s law and/or canonical momentum relation. The fact that minimum unit of the quantized magnetic flux is hc/2e does not mean the concurrent motion of the two electrons in a Cooper pair as is known so far. However, it is shown to be related with independent motion of the each electron in a superconducting state.

The Importance of Being Discrete in Sex

Authors: Renato Vieira dos Santos
Comments: 11 Pages.

The puzzle associated with the cost of sex, an old problem of evolutionary biology, is discussed here from the point of view of nonequilibrium statistical mechanics. The results suggest, in a simplified model, that the prevalence of sexual species in nature can be a natural and necessary consequence of the discrete character of the nonlinear interactions between couples and their pathogens/parasites. Mapped into a field theory, the stochastic processes performed by the species are described by continuous fields in space and time. The way that the model's parameters scale with subsequent iterations of the renormalization group gives us information about the stationary emergent properties of the complex interacting systems modeled. We see that the combination of one aspect of the Red Queen theory with the stochastic processes theory, including spatiotemporal interactions, provides interesting insights into this old Darwinian dilemma.
