In this article, we consider the free boundary value problem for one-dimensional compressible bipolar Navier-Stokes-Possion (BNSP) equations with density-dependent viscosities. For general initial data with finite energy and the density connecting with vacuum continuously, we prove the global existence of the weak solution. This extends the previous results for compressible NS [27] to NSP.

EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope, due to be completed in 2012. The primary goal of EMU is to make a deep (∼10μJy/bm rms) radio continuum survey of the entire Southern Sky at 1.4 GHz, extending as far North as +30◦ declination, with a 10 arcsec resolution. EMU is expected to detect and catalog about 70 m...

The m-testing of model specification pioneered by Newey (1985) and Tauchen (1985) and extended by White (1987) offers a general framework that unifies many specification tests in the literature. Within the m-testing framework, we consider how to test the hypothesis that a model is correctly specified in each of many groups in the population under study, where each of the groups offers only a fe...

Multidimensional lossless networks are of special interest for use as reference structures for multidimensional wave digital filters [1]-[3]. The starting point of the presented synthesis procedure for two-dimensional representatives of the networks mentioned is a scattering matrix description of the desired multiport. This given matrix is assumed to have those properties which have turned out ...

We propose a scheme to measure quantum Stokes parameters, their fluctuations and correlations. The proposal involves measurements of intensities and intensity-intensity correlations for suitably defined modes, which can be produced by a combination of half wave and quarter wave plates. ∗email: [email protected] †email: [email protected]

We utilize the DHM integral representation for the BES dressing factor of the world-sheet S-matrix of the AdS5×S light-cone string theory, and the crossing equations to fix the principal branch of the dressing factor on the rapidity torus. The results obtained are further used, in conjunction with the fusion procedure, to determine the bound state dressing factor of the mirror theory. We convin...

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...
