A linear transmitter with correlated Gaussian white additive and multiplicative noises and a periodic signal coupled either additively or multiplicatively is considered. The correlations have a weak destructive effect in case of the additive signal and a strong constructive effect in case of the multiplicative one. Analytical results for the linear transmitter with the additive signal agree wit...

Diffraction gratings are used inmany fields in physics, especially astronomy. In astronomy, diffraction gratings are used in spectrographs to analyze the light of astronomical objects that is gathered by telescopes. These gratings use the principles of constructive and destructive interference of light to spread the different wavelengths out based on the wave nature of light and the diffraction...

Dicke superradiance has been observed in many systems and is based on constructive interferences between many scattered waves. The counterpart of this enhanced dynamics, subradiance, is a destructive interference effect leading to the partial trapping of light in the system. In contrast to the robust superradiance, subradiant states are fragile, and spurious decoherence phenomena hitherto obstr...

We demonstrate, via simulation and experiment, slowing down of a phase-modulated optical signal. A 10.7-Gb/s NRZ-DPSK signal can be delayed by as much as 42 ps while still achieving error free via broadband SBS-based slow light. We further analyze the impact of slow-light-induced data-pattern dependence on both constructive and destructive demodulated ports. By detuning the SBS gain profile, we...

We present optical fields formed by superposing nondiffracting parabolic beams with distinct longitudinal wave-vector components, generating light profiles that display intensity fluxes following parabolic paths in the transverse plane. Their propagation dynamics vary depending on the physical mechanism originating interference, where the possibilities include constructive and destructive inter...

We study frustrated quantum systems from a quantum information perspective. Within this approach, we find that highly frustrated systems do not follow any general "area law" of block entanglement, while weakly frustrated ones have area laws similar to those of nonfrustrated systems away from criticality. To calculate the block entanglement in systems with degenerate ground states, typical in fr...

This paper is addressed to economic problems for which many different solutions (models) can be proposed. In such situation the ensemble approach is a natural way to improve the final prediction results. In particular, we present the method for the prediction improvement in multi-agent environment based on the multivariate decompositions. As a decomposition method we present the smooth componen...

The ω-meson photoproduction, γ+p → p+ω, is studied in the framework of a model, containing π-meson exchange in t-channel and nucleon-exchange in sand u-channels. Considering both ωNN -coupling constants in the region of time-like meson four momenta as the free parameters, we find different sets of solutions for these constants from the existing data on the t-dependence of the differential cross...

The unit interval vertex deletion problem asks for a set of at most k vertices whose deletion from an n-vertex graph makes it a unit interval graph. We develop an O(k4)-vertex kernel for the problem, significantly improving the O(k53)-vertex kernel of Fomin, Saurabh, and Villanger [ESA’12; SIAM J. Discrete Math 27(2013)]. We introduce a novel way of organizing cliques of a unit interval graph. ...

We examine the relationship between the incidence of workplace deviance (on-the-job crime) and the state of the economy. A worker’s probability of future employment depends on whether she has been deviant as well as on the availability of jobs. Using a two period model we show that the net impact on deviant behavior to changes in unemployment can go either way depending upon the nature of the e...
