Book Description
Reconstruction of cosmic ray arrival directions for Surface Detectors (SD) and Fluorescence Detectors (FD) of the Pierre Auger Observatory requires accurate timing (25 nanoseconds or better) between measurements at individual detectors and instrument triggers. Timing systems for both SD and FD are based on Motorola Oncore UT+ GPS receivers installed into custom-built time-tagging circuits that are calibrated in the laboratory to a statistical precision of better than 15 ns. We describe timing calibration and synchronization methods applied in the field for both the SD and the FD systems in four areas: (1) checks of timing offsets within the SD using co-located station pairs and timing residuals on reconstructed showers, (2) calibration within the FD using a custom-build LED calibration system, (3) calibration between SD and FD using laser signals fed simultaneously into an SD station and across the FD via the Central Laser Facility (CLF), and (4) studies of synchronization between FD and SD through the analysis of events detected by both systems, called hybrid events. These hybrid events allow for a much more accurate reconstruction of the shower and for relatively tight constraints on timing calibration offsets. We demonstrate that statistical and systematic timing uncertainties have no significant impact on the event reconstruction.

Book Description
The Fourth International Conference on Particle Physics Beyond the Standard Model (BEYOND THE DESERT '03 - Accelerator, Non-accelerator and Space Approaches) was held during June 9-14, 2003 at Castle Ringberg, Tegernsee, Germany. Traditionally the Scientific Program of the BEYOND conferences, which we started in 1997, covers most of the prominent topics of modern par ticle physics and astrophysics (see CERN Courier November 1997, pp. 16-18, and March 2003, pp. 29-30). At this conference one of the topics on which we put major emphasis were new theoretical developments in extensions of the Stan dard Model by Supergravity - which had its twentieth birthday in this year -, by Superstrings and by Extra Dimensions. Two of the 'inventors' of the first superspace formulation of supergravity - Pran Nath and Richard Arnowit- were participants at this meeting. These topics were discussed by Pran Nath (Boston), Dick Arnowitt (Texas A&M) - who concentrated on the connection to dark matter and g-2 of the muon -, A. E. Faraggi (Oxford, UK), R. E. Allen (Texas A&M) and A. Kobakhidse (Helsinki Univ. ). Fundamental symmetries, including CP violation beyond the Standard Mo del, a possible time variation of the QCD scale, and the status of preons, were dis cussed by Peter Herczeg (Los Alamos), M. N. Rebelo (Lisboa, Portugal), R. Leh nert (Algarve Univ., Portugal), Harald Fritzsch (Munich) and S. Fredriksson (Lulea Univ., Sweden)."

Book Description
The handbook centers on detection techniques in the field of particle physics, medical imaging and related subjects. It is structured into three parts. The first one is dealing with basic ideas of particle detectors, followed by applications of these devices in high energy physics and other fields. In the last part the large field of medical imaging using similar detection techniques is described. The different chapters of the book are written by world experts in their field. Clear instructions on the detection techniques and principles in terms of relevant operation parameters for scientists and graduate students are given.Detailed tables and diagrams will make this a very useful handbook for the application of these techniques in many different fields like physics, medicine, biology and other areas of natural science.

Book Description
With dark secrets underground and hints of the occult, this is a must for readers of Adam Nevill and Susan Hill. "[...]if there is a crown of queen of gothic horror, [Catherine Cavendish] should be wearing it." — Modern Horrors Eligos is waiting…fulfil your destiny 1941. In the dark days of war-torn London, Violet works in Churchill's subterranean top secret Cabinet War Rooms, where key decisions that will dictate Britain’s conduct of the war are made. Above, the people of London go about their daily business as best they can, unaware of the life that teems beneath their feet. Night after night the bombs rain down, yet Violet has far more to fear than air raids. A mysterious man, a room only she can see, memories she can no longer trust, and a best friend who denies their shared past... Something or someone - is targeting her.

Book Description
This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments. It also covers applications in medicine and life sciences. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
