The cold universe is the part of the universe in a cold form close to the background radiation temperature. Until recently, this cold state has been neglected because it is hard to observe, although it must inevitably play a crucial role as the original state of most of the hotter observable objects such as planets, stars, and galaxies. Fortunately, the cold universe currently becomes more and more accessible with newer instruments. This book contains the printed version of the lectures given at the 32nd Saas-Fee Advanced Course "The Cold Universe" by three eminent scientists in the field: Andrew Blain, Francoise Combes and Bruce Draine. Cold objects at cosmological distances, the origin of galaxies, the role of molecules in galaxies, and the physics of the dust in cold clouds are the main topics treated. This book contains an accessible and up-to-date review of the field and should be useful for many years to astronomy students, cosmologists, physicists and researchers.

Logics have, for many years, laid claim to providing a formal basis for the study and development of applications and systems in arti?cial intelligence. With the depth and maturity of formalisms, methodologies and logic-based systems - day, this claim is stronger than ever. The European Conference on Logics in Arti?cial Intelligence (or Journ´ ees Europ´ eennes sur la Logique en Intelligence Arti?cielle, JELIA) began back in 1988, as a workshop, in response to the need for a European forum for the discussion of emerging work in this ?eld. Since then, JELIA has been organized biennially, with English as its o?cial language, previous meetings taking place in Rosco?, France (1988), Amsterdam, Nether- ´ lands (1990), Berlin, Germany (1992), York, UK (1994), Evora, Portugal (1996), Dagstuhl,Germany(1998),M´ alaga,Spain(2000)andCosenza,Italy(2002). The increasinginterestinthisforum,itsinternationallevelwithgrowingparticipation from researchers outside Europe, and the overall technical quality have turned JELIA into a major biennial forum for the discussion of logic-based approaches to arti?cial intelligence. The 9th European Conference on Logics in AI, JELIA 2004, took place in Lisbon, Portugal, between the 27th and the 30th of September 2004, and was hosted by the Universidade Nova de Lisboa. Its technical program comprised 3 invited talks, by Francesca Rossi, Franz Baader, and Bernhard Nebel, and the presentationof52refereedtechnicalarticlesselectedbytheProgramCommittee among the 144 that were submitted, a number which in our opinion clearly indicates that the research area of logics in AI is one with a great and increasing interest.

Although the Standard Model of strong and electroweak interactions describesparticle physics phenomena up to the vector boson mass scale very well, it is in general believed that it is not the ultimate theory. The aim of this series of seminars was to initiate discussions between field theorists and phenomenologically oriented high energy physicists on the observable consequenses of the concept of SUSY. The subjects covered by the individual contributions include an introduction to the basic features of SUSY models, in particular the minimal supersymmetric Standard Model, followed by discussions of the theoretical predictions and experimental findings on the particle content and mass spectra, cosmological consequenses, indirect manifestations through quantum effects, radiative corrections in the supersymmetric Higgs sector, and the concept of dynamical electroweak symmetry breaking in the context ofSUSY. These topics are treated at a level appropriate for advanced students.However, the book should also be useful for teachers and researchers.

Chiral dynamics provides a rigorous and model-independent methodology for making QCD predictions at the confinement scale. This helps particularly in the testing of the standard model. The workshop reported here was focused on theoretical predictions and the measurements of physical processes, analyzing carefully the phenomenology needed to bridge the gap between the two. Besides the lectures, this volume also contains summaries of the working groups on Â-Â-scattering, ÂN-interaction, photo/electro-pion-production, and on chiral anomaly. This book is a thorough review of the state of the art and it addresses researchers as well as graduate students.
