Top Quark Mass Measurements at CDF

The mass of the top quark M_top is interesting both as a fundamental parameter of the standard model and as an important input to precision electroweak tests. The Collider Detector at Fermilab (CDF) has a robust program of top quark mass analyses, including the most precise single measurement, M_top = 173.4 +/- 2.8 GeV/c^2, using 680 pb^-1 of ppbar collision data. A combination of current results from CDF gives M_top = 172.0 +/- 2.7 GeV/c^2, surpassing the stated goal of 3 GeV/c^2 precision using 2 fb^-1 of data. Finally, a combination with current D0 results gives a world average top quark mass of 172.5 +/- 2.3 GeV/c^2.Comment: 8 pages, Contribution to Proceedings of the 41st Rencontres de Moriond: Electroweak Interactions and Unified Theories, La Thuile, Italy, 11-18 March 200

Who knows what when? : The information content of pre-IPO market prices : [Version March/June 2002]

To resolve the IPO underpricing puzzle it is essential to analyze who knows what when during the issuing process. In Germany, broker-dealers make a market in IPOs during the subscription period. We examine these pre-issue prices and find that they are highly informative. They are closer to the first price subsequently established on the exchange than both the midpoint of the bookbuilding range and the offer price. The pre-issue prices explain a large part of the underpricing left unexplained by other variables. The results imply that information asymmetries are much lower than the observed variance of underpricing suggests

From Jet Counting to Jet Vetoes

The properties of multi-jet events impact many LHC analysis. The exclusive number of jets at hadron colliders can be described in terms of two simple patterns: staircase scaling and Poisson scaling. In photon plus jets production we can interpolate between the two patterns using simple kinematic cuts. The associated theoretical errors are well under control. Understanding such exclusive jet multiplicities significantly impacts Higgs searches and searches for supersymmetry at the LHC.Comment: 4 pages, 4 figures, to appear in the proceedings of XX International Workshop on Deep-Inelastic Scattering and Related Subjects, 26th-30th March 2012, University of Bon

Broadband universal service in Europe:A review of policy consultations 2005-2010

Recognition of the growing importance of broadband to the public presents challenges for policy-makers in introducing efficient strategies, not only to serve the increasing demand for broadband among people in society but also to increase their economic contribution both in the short run and in the long run. Different measures and strategies have been implemented in many countries and regions in order to encourage broadband deployment. Among them, the inclusion of broadband in the scope of universal service has been discussed.In the European Union, the discussion on broadening the scope of the Universal Service Directive (USD) to include broadband has been raised since the first periodical review in 2005. At that time, the European Commission concluded that only a small, although rapidly growing, minority of European consumers currently make use of broadband services. Therefore, the conditions for including broadband services within the scope of universal service as set out in the USD were not fulfilled. Later, the European Commission launched the second periodical review of universal service in 2008 with the preliminary conclusion that broadband has not yet reached the majority of people, implying that the conditions of the USD for expanding the scope of universal service were not yet fulfilled. However, the public consultation on broadening the scope of the USD to include broadband has been opened since March 2010 and was last on May 7, 2010. In the meantime, the public workshop organized in the context of the public consultation on universal service principles in e-communications was held on March 30, 2010. The workshop provided wide-ranging views on the topic, including an assessment of the cost of broadband availability and also the rapid change of broadband penetration rate throughout Europe. Against this background, this paper provides an analytical survey of the current state and trends of universal service with focus on broadband access in the European Union. First it presents an overview of broadband deployment and regulation in Europe. Then, it analyzes the USD reviews by taking into account the previous and the recent review, in particular by comparing the discourse evolution of the public submissions from stakeholders in the two consultations. A framework to evaluate broadband universal service will be provided. In conclusion, the paper will identify selected issues regarding broadband universal service in Europe, especially the pros and cons of broadband universal serviceuniversal service obligation, broadband, legislations, public consultaitons

The Potential of Deconstruction in Buffalo, New York

Building deconstruction is not a novel idea but represents an ancient practice reinvented for our modern era. Deconstruction is an environmentally friendly (yet fiscally remunerative) alternative to traditional building demolition. Deconstruction is: [t]he process of carefully dismantling a building in order to salvage components for reuse and recycling. Typically, a small team of skilled and licensed professionals disassemble the structure, setting aside the valuable materials for direct reuse or resale, before recycling the rest. In most instances, deconstruction is combined with an element of demolition, with the latter process plugging the gaps not covered by the former process. Deconstruction has traditionally been used successfully with decommissioned military bases and all-wood barns. Building deconstruction is simply an expansion of this practice to both commercial and residential structures. In fact, it can be argued that deconstruction is the original demolition
