The Raman polarizer is a Raman amplifier which not only amplifies but also repolarizes light. We propose a relatively simple and analytically tractable model - the ideal Raman polarizer, for describing the operation of this device. The model efficiently determines key device parameters such as the degree of polarization, the alignment parameter, the gain and the RIN variance.

We obtain a ‘stability estimate’ for strong solutions of the Navier–Stokes system, which is an Lα-version, 1 < α < ∞, of the estimate that Serrin [Se] used in obtaining uniqueness of weak solutions to the Navier-Stokes system. By applying this estimate, we obtain new results in stability and uniqueness of solutions, and non-blowup conditions for strong solutions.

This paper reviews the constraints imposed on the solar neutrino mixing parameters by data collected by the Sudbury Neutrino Observatory (SNO). The SNO multivariate analysis is reviewed. The global solar neutrino analysis is emphasized in terms of matter-enhanced oscillation of two active flavors. An outline of how SNO uses the data to produce oscillation contour plots and how to include the re...

In this paper, a regression type estimator representing a class of estimators is proposed to estimate the population mean of the study variable. The bias and mean square error of the proposed estimator are obtained. Also the optimizing value of the unknown parameter is derived and the expression of minimum mean square error is obtained. Further since the proposed estimator is biased, a jackknif...

BACKGROUND A recent drug interaction study reported that when azithromycin was administered with the combination of ivermectin and albendazole, there were modest increases in ivermectin pharmacokinetic parameters. Data from this study were reanalyzed to further explore this observation. A compartmental model was developed and 1,000 interaction studies were simulated to explore extreme high iver...

Properties of scalar–isoscalar mesons are analysed in an unitary model using separable interactions in three decay channels: ππ , KK and an effective 2π2π. We obtain different solutions by fitting various data on the ππ and KK phase shifts and inelasticities including the CERN-Cracow-Munich measurements of the πp↑ → π+π−n reaction on a polarized target. Analytical structure of the meson-meson m...

A central concern of linguistic theory is to account for how the arguments of a given lexical item are associated with positions in a syntactic structure. Many theorists hold that this mapping is mediated by a so-called thematic hierarchy. In Principles-and-Parameters style theories this typically works as follows. A verb selects arguments with certain thematic (θ-) roles. These θ−roles are ran...

A set of type-(m, n) S is a set of points of a design with the property that each block of the design meets either m points or n points of S. The notions of type and of parameters of a k-set (there called characters) were introduced for the first time by Tallini Scafati in [M. Tallini Scafati, {k, n}-archi di un piano grafico finito, con particolare riguardo a quelli con due caratteri. Note I a...

This paper presents a discussion of the susceptibility of human factors to the use of folk models. The case of automation-induced complacency is used as a guiding example to illustrate how folk models (1) substitute one label for another rather than decomposing a large construct into more measurable specifics; (2) are immune to falsification and so resist the most important scientific quality c...
