Описание: Matthias W?rlpresents two essential steps to implement offline PET monitoring of proton dosedelivery at a clinical facility, namely the setting up of an accurate MonteCarlo model of the clinical beamline and the experimental validation ofpositron emitter production cross-sections. In the first part, the field sizedependence of the dose output is described for scanned proton beams. Both theMonte Carlo and an analytical computational beam model were able to accuratelypredict target dose, while the latter tends to overestimate dose in normaltissue. In the second part, the author presents PET measurements of differentphantom materials, which were activated by the proton beam. The resultsindicate that for an irradiation with a high number of protons for the sake ofgood statistics, dead time losses of the PET scanner may become important andlead to an underestimation of positron-emitter production yields.

Описание: This book is devoted to an investigation of the vacuum of quantum elec trodynamics (QED), relying on the perturbative effective action approach. In the high energy domain, we observe similarities between a vacuum with a superstrong magnetic field and a magnetized plasma.
Описание: Introduction.- Part I Single-Site- and Single-Atom-Resolved Detection of Atomic Limit Mott Insulators.- Superfluid-Mott-Insulator Transition.- Overview of the Experimental Procedure.- Single-Site-Resolved Imaging and Thermometry of Atomic Limit Mott Insulators.- Part II Single-Site- and Single-Atom-Resolved Detection of Correlation Functions.- Detection of Particle-Hole Pairs Using Two-Site Correlation Functions.- Non-Local Correlations in One Dimension.- Non-Local Correlations in Two Dimensions, Duality and Distribution Functions.- Part III 'Higgs' Amplitude Mode.- Introduction to Amplitude and Phase Modes.- Detection of the Higgs Amplitude Mode at the 2d SF-Mott-Insulator Transition.- Outlook.- Part IV Appendix.- Appendix A Experimental Details.- Appendix B Numerical Methods for Correlation Functions.- Appendix C Calculation for Non-Local Correlations in One Dimension.- Appendix D Calculation for Non-Local Correlations in Two Dimensions.
In The Scientist and the Forger: Probing a Turbulent Art World the author draws upon an enthralling range of case studies, from Botticelli to Leonardo, Campendonk to Pollock and Chagall to Freud, equipping the reader with a holistic understanding of an art world shaped by fast-moving trends, and increasingly permeated by science. We are taken on a gripping journey, becoming witness to the attempts currently being made to safeguard a partly complicit art market virtually under siege.
How can we determine whether it was Leonardo's hand that created Salvator Mundi? How can we prove that a suspected Pollock is a forgery? And how can Man in a Black Cravat be seemingly incontrovertibly attributed to Lucian Freud, despite this artist's adamant refusal to recognize it as one of his own? This book reveals how art historians and scientists collaborate conclusively to authenticate paintings or demonstrate that they are forgeries, and as the enigma of La Bella Principessa continues to baffle, the question remains: do we have enough reason to hope that we shall one day know her true story? Building on the first edition, a more in depth look is taken at some of the greatest scandals to date -- with an interpretation of the psychological behavior of Ann Freedman the former president and director of the Knoedler Gallery.

Описание: Physicists actively engaged in advanced research should be en- couraged to discuss results and deepen their theoretical understand- ing of the data. It is practically impossible nowadays to achieve the goal of the old times when small groups of scientists had the privilege of debating their ideas and the details of their experi- ments in an informal and friendly way. Conferences are now too wide in scientific coverage and, in consequence, there are often too many participants. The Highly Specialized Seminars of the Ettore Majorana Centre for Scientific Culture are intended to provide such a forum for scientists of outstanding reputation in their fields to exchange information. This volume deals with one of the most interesting topics in subnuclear physics, and Professor Giuliano Preparata is one of the world's leaders in the field. This volume contains the most recent results on the study of deep inelastic phenomena, using neutrinos, muons and electrons against nucleons, and (e+e-) interactions. It represents our best knowledge of the field as given by some of the most distinguished world experts in the theoretical and experimental domain. Antonino Zichichi, Director Ettore Majorana Centre for Scientific Culture v PREFACE In March 1979, about 50 physicists gathered in Erice to parti- cipate in the Fourth Highly Specialized Seminar on "Probing Hadrons with Leptons."

Описание: This book introduces the reader to how fundamental topics in particle physics can be studied with the largest neutrino telescopes currently in operation. Due to their large size, reaching cubic-kilometer volumes, and their wide energy response, these unusual detectors can provide insight on neutrino oscillations, dark matter searches or searches for exotic particles, new neutrino interactions or extra dimensions, among many other topics.Lacking a man-made neutrino 'beam', neutrino telescopes use the copious flux of neutrinos continuously produced by cosmic rays interacting in the Earth's atmosphere, as well as neutrinos from astrophysical origin. They have therefore access to neutrinos of higher energies and much longer baselines than those produced in present accelerators, being able to search for new physics at complementary scales than currently available in particle physics laboratories around the world.Written by carefully chosen experts in the field, the book introduces each topic in a pedagogical way apt not only to professionals, but also to students or the interested reader with a background in physics.
