Domain Walls and Vortices with Non­Symmetric Cores Minos Axenides 1 Institute of Nuclear Physics, N.C.S.R. Demokritos 153 10, Athens, Greece Leandros Perivolaropoulos 2 Department of Physics, University of Crete 71 003 Heraklion, Greece We review recent work on a new class of topological defects which possess a non­symmetric core. ... After a rescaling \Phi ! ... We constructed a two dimensional simulation of the field evolution of domain wall bubbles with both symmetric and non­symmetric core. ...

... The gamma function [not the Gamma -- note upper-case G -- which is related to the factorial] is one of those insanely useful functions that after one finds out about it, one wonders ?why haven?t we been using this all the time?? It is defined only on the positive non-negative real line, is a highly flexible function that can emulate almost any kind of skewness in a distribution, and is a perfect complement to the Poisson likelihood. ...

between bottom maps and sonar and hooks that can be trolled at any level - with a sort of airplane plus weights arrangement - and legal limits on net sizes (length and depth), it is now possible to both count salmon more efficiently and also to capture an appropriate percentage while leaving enough escapement for the next generation under ideal circumstances. ocean temp changes and more ruthless foreign fishing in russian zone and escaped farm ...

... Many of the beautiful photos in astronomy textbooks were taken by amateur astronomers using everyday camera equipment. With Comet Hale-Bopp fast approaching, now is a perfect time to learn the not-too-difficult science and art of still-camera astrophotography. ... The Pentax K-1000 is one such camera. ... Data should include date, location, sky conditions, camera and lens specs, film type, and the time, subject, and length of each exposure. ... Slides show exactly what you photographed. ...

This means light from very far away has to struggle to overcome that expansion to get to us, which means the light loses energy (like you have to use energy to pedal a bicycle up a hill). ... This theory is usually called "tired light", and is used to explain the redshift of light without needing a Big Bang scenario. ... 2008 Phil Plait. ...

... The crucial problem that limits our knowledge of our own galaxy, and prevents us from working out how and when it formed, is our inability to measure direct distances to distant stars, and to determine their proper motions. If we could get accurate parallaxes and proper motions for every star in the galaxy, we'd have things completely wrapped up, and surely we'd be able to figure out galaxy formation. ... Luckily, this is just what should be achievable using space interferometers. ...

Configuration Files | ... Options | ... This version of Apache includes changes allowing it to run on IBM's EBCDIC-based TPF (Transaction Processing Facility) operating system. ... It is passed to Apache through the ZINET XPARM field since ZINET is the only way to start the server on TPF. A third group of options apply to both the informational displays (ZFILE) and running the server (ZINET XPARM): -d, -D and -f. The rest of Apache's options are either not applicable or are not supported on TPF. ...
