The D0 experiment has previously calculated its luminosities using a visible cross section (luminosity monitor constant) for its Level 0 trigger, [sigma][sub L0]= 42.9 mb based on the E710 inelastic cross section measurements. Recently, CDF has also published inelastic cross section measurements markedly different from E710. The D0 experiment has moved to world average inelastic cross sections at[radical]s= 1.8 TeV. The result changes the D0 visible cross section to[sigma][sub L0]= 48.2 mb which is an increase of 12.4% in the visible cross section value. The error on luminosity has been left unchanged at 12%.

The D0 experiment has previously calculated its luminosity using the visible cross section (luminosity monitor constant) for its Level 0 trigger, [sigma][sub L0]= 48.2 mb, based on the world average[ovr p]p inelastic cross sections at[radical]s= 1.8 TeV. The error on luminosity had been set at 12%. Recent studies using the MBR and DTUJET Monte Carlo event generators and unbiased D0 data samples have resulted in a more precise determination of the D0 luminosity monitor constant. The result, [sigma][sub L0]= 46.7[+-] 2.5 mb, lowers the central value by 3.1% and reduces the error to 5.4%. 12 refs., 7 figs., 9 tabs.

The D0 experiment calculates its luminosity using the visible cross section (luminosity monitor constant) [sigma]{sub L0} for its Level 0 trigger based on the world average {anti p}p inelastic cross sections at √s - 1.8 TeV. For the 1992-1993 Tevatron Run (1A), the luminosity monitor constant was determined to be [sigma]{sub L0} = 46. 7±2.5 mb. For the 1994-1996 Tevatron Run (1B/1C), the luminosity monitor constant changed slightly with an upgrade to the electronics in the Level 0 trigger. The luminosity monitor constant becomes on average [sigma]{sub L0} - 44.53 ± 2.37 mb for Run 1B/1C. In addition, small corrections for halo and multiple single diffraction are included in integrated luminosity determinations.

D0 has calculated the luminosity monitor constant for[radical]s= 630 GeV. The inelastic p[anti p] cross section was interpolated between measurements performed at[radical]s= 546 and 1800 GeV. The geometric acceptance, hardware efficiency, and luminosity-dependent corrections are similar to those previously published for the full Tevatron energy. We find a luminosity-weighted value of[sigma][sub L0]= 34.04[+-] 1.05 mb, yielding a precision of[+-] 3.08%.

The luminosity system is an integral part of the D0 detector that must be properly maintained to provide accurate luminosity measurements for physics analysis. After the addition of a readout layer to the silicon vertex detector in 2006, it was necessary to re-calculate the effective inelastic cross section to which the luminosity monitor is sensitive. The preliminary analysis showed that the luminosity constant did not change with the addition of the extra layer of silicon. A full study of the revised luminosity constant including a complete analysis of systematic uncertainties has been completed. The luminosity constant was determined to be [sigma]{sub eff} = 48.3 ± 1.9 ± 0.6 mb, which reduces the D0 contribution to the luminosity measurement uncertainty by almost 3%.

A COMPANION TO WITTGENSTEIN The most comprehensive survey of Wittgenstein’s thought yet compiled, this volume of fifty newly commissioned essays by leading interpreters of his philosophy is a keynote addition to the Blackwell Companions to Philosophy series. Full of penetrating insights into the life and work of the most important philosopher of the twentieth century, the collection explores the full range of Wittgenstein’s contribution to philosophy. It includes essays on his intellectual development, his work in logic and mathematics, philosophy of language, philosophy of mind and action, epistemology, ethics, philosophy of religion, and much else. As well as examining Wittgenstein’s contribution to human understanding in detail, the Companion features vital contextual analysis that traces the relationship between his ideas and those of other philosophers and schools of thought, including the Aristotelian and continental philosophical traditions. Authors also address prominent themes that remain current in today’s philosophical debates, explaining Wittgenstein’s continuing legacy alongside his historical significance. Essential reading for scholars of philosophy at all levels, A Companion to Wittgenstein combines engaging commentary with unrivaled academic authority.

The International Symposium on Experimental Robotics (ISER) is a series of bi-annual meetings which are organized in a rotating fashion around North America, Europe and Asia/Oceania. The goal of ISER is to provide a forum for research in robotics that focuses on novelty of theoretical contributions validated by experimental results. The meetings are conceived to bring together, in a small group setting, researchers from around the world who are in the forefront of experimental robotics research. This unique reference presents the latest advances across the various fields of robotics, with ideas that are not only conceived conceptually but also verified experimentally. It collects contributions on the current developments and new directions in the field of experimental robotics, which are based on the papers presented at the Ninth ISER held in Singapore.

This book provides a comprehensive and up-to-date guide to the AMOLED technologies and applications which have become industry standard in a range of devices, from small mobile displays to large televisions. Unlike other books on the topic, which cover the fundamentals, materials, processing, and manufacturing of OLEDs, this one-stop book discusses the core components, such as TFT backplanes, OLED materials and devices, and driving schematics together in one volume with chapters written by experts from leading international companies in the field of OLED materials and OLED TVs. It also examines emerging areas, such as micro-LEDs, displays using quantum dots, and AR & VR displays. Presenting the latest research trends as well as the basic principles of each topic, this book is intended for undergraduate and postgraduate students taking display-related courses, new researchers, and engineers in related fields.
