Proceedings of the Particle Physics and Early Universe Conference (PPEUC). For this paper: postscript PPEUC CMB index 1 Introduction.. ... We review recent work on a new class of topological defects which possess a non-symmetric core. They arise in scalar field theories with global symmetries, for domain walls and for vortices, which are explicitly broken to and respectively. ... 2 Domain Walls with Non-Symmetric Cores . 3 Vortices with Non-symmetric Core . ...

... These were 2-port VNA measurements taken on selected combinations of antennas designed to fill in all the points on a 6-port S-parameter matrix, taking heavy advantage of reciprocity and of expected symmetries. ... In the table to follow these notes, the complex S-parameter values have been adjusted to reflect the impedances at the actual dipole terminals, accounting both for the 8-foot offset and for individual losses in the heliax lines. ...
... The radial PSF distribution of the filter FilterId is tabulated in the extension PSF- FilterId . ... radial PSF of U-filter . ... radial PSF of UVW1-filter . ... radial PSF of UV grism 1st order (TBC) . ... The value of the cumulative PSF is normalized to 1.0 at this fixed aperture radius. The aperture radius is listed for each filter elements in the keyword APERTURE. ... Therefore the aperture radius is listed separately for each filter in the keyword APERTURE of the filter extensions. ...
... Behemoth black hole found in an unlikely place . ... galaxies . ... black holes . ... Study reveals a remarkable symmetry in black hole jets . ... The result provides a tantalizing hint that common physical processes are at work. т??What weт??re seeing is that once any black hole produces a jet, the same fixed fraction of energy generates the gamma-ray light we observe with Fermi and Swift,т?? said Rodrigo Nemmen from NASAт??s Goddard Space Flight Center in Greenbelt, Maryland. ...
... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...
... Modelling the Global GLE Response . ... Ground level enhancements (GLEs) are sudden increases in the cosmic ray intensity recorded by ground based detectors. GLEs are invariably associated with large solar flares but the acceleration mechanism producing particles of up to tens of GeV is not understood. ... Figure 23 shows the undisturbed and disturbed viewing directions for vertical incidence particles at a number of neutron monitors at 1805 UT during the GLE on 22 October 1989. ...
... Archives . ... P Values: What They Are and How to Use Them . ... That is, if we derive a posterior probability distribution function for a parameter using one dataset, we can apply that as the prior when a new dataset comes along, and thereby improve our estimates of the parameter and shrink the error bars. ... Suppose you have two data sets, D1 and D2, hypotheses H, and background info (model, etc.) ... Comment ( RSS ) | ... Entries RSS . ... Chandra Blog . ... Entries (RSS) and Comments (RSS) . ...
... PISTON piston . ... this command is not used by the TCC The guide camera mechanical controller sets the filter, focus and other mechanical functions, but not the position of the guide camera in the focal plane. Positioning, if available, is handled by one or two guider position axes controllers , one per axis of motion. ... Notifies the controller that subsequent commands apply to the guider mechanical controller. ... Sets the piston of the guider to the specified value (in decimal microns). ...
... A Flag for Mars . ... A Flag for Your Planet Activity . ... This Mars flag was a red, green, and blue tricolor. ... Red stands for the current desert, green for a 2nd step planet with vegetation and blue for the fully terraformed blue planet Mars. ... The tricolor flag design is similar to the flags of many nations, including the following flags that have two of the three colors of the red, green, and blue tricolor Mars flag: . ... red . ... The official proportions of the U.S. flag are 10 x 19. ...
These are some notes on the Apache API and the data structures you have to deal with, etc. ... See the TODO file for what might be coming). ... Handlers, Modules, and Requests . ... A final note on the declared types of the arguments of some of these commands: a pool is a pointer to a resource pool structure; these are used by the server to keep track of the memory which has been allocated, files opened, etc. , either to service a particular request, or to handle the process of configuring itself. ...
... Return to Dopita's Home Page . Paper presented at: 2me. ... Nebular densities derived from O IV] and Si III] emission line ratios are found to be larger than densities derived from the visible [O II] or [S II] ratios, indicating that the regions nearest the star are denser. ... From a set of line diagnostic diagrams, we find that LINER galaxies, narrow line radio galaxies and cooling flow emission regions can be modelled in terms of fast shocks in a relatively gas poor environment. ...

Как у Земли, Юпитера и Сатурна, у Урана есть магнитный хвост, состоящий из захваченных полем заряженных частиц, растянувшийся на миллионы километров за Уран от Солнца. ...
... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...
