Self-aligning fixture used in lathe chuck jaw refacing

Self-aligning tool positions and rigidly holds lathe chuck jaws for refacing and truing of the clamping surface. The jaws clamp the fixture in the manner of clamping a workpiece. The fixture can be modified to accommodate four-jawed checks

Making Government Work

For a city or state government to be viable in the last decade of the 20th century, elected leaders must view modern management as a crusade. The work force must receive fair and equitable compensation, and all must be committed to constant quality improvement. Newspapers, magazines, radio and television must report the success stories and the failures. Taxpayers must understand that government services can improve, and the leaders must be held accountable. This is possible throughout the country but it will not happen unless an educated electorate demands it and the elected officials understand the stakes and urgency involved

Market Size in Innovation: Theory and Evidence From the Pharmaceutical Industry

This paper investigates the effect of (potential) market size on entry of new drugs and pharmaceutical innovation. Focusing on exogenous changes driven by U.S. demographic trends, we find that a 1 percent increase in the potential market size for a drug category leads to a 4 to 6 percent increase in the number of new drugs in that category. This response comes from both the entry of generic drugs and new non-generic drugs, and is generally robust to controlling for a variety of non-profit factors, pre-existing trends

Corporate Average Fuel Economy Standards and the Market for New Vehicles

This paper presents an overview of the economics literature on the effect of Corporate Average Fuel Economy (CAFE) standards on the new vehicle market. Since 1978, CAFE has imposed fuel economy standards for cars and light trucks sold in the U.S. market. This paper reviews the history of the standards, followed by a discussion of the major upcoming changes in implementation and stringency. It describes strategies that firms can use to meet the standards and reviews the CAFE literature as it applies to the new vehicle market. The paper concludes by highlighting areas for future research in light of the upcoming changes to CAFE.CAFE, costs, structural estimation

First minimum bias physics results at LHCb

The goal of the LHCb experiment is the indirect search for New Physics through precision measurements of B-decays. A short description of the detector and its performance after the first data taking in 2009 and 2010 will be presented. In addition first preliminary results of a $\rm K_{s}$ differential cross section measurement at a center of mass energy of $\sqrt{s} = 900\; \rm GeV$ and a measurement of the $\frac{\bar{\lambda}}{\lambda}$ production ratio at $\sqrt{s} = 900\; \rm GeV$ and $\sqrt{s} = 7\; \rm TeV$ will be discussed.Comment: Invited talk presented at the XVI International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI 2010), Batavia, IL, USA (28 June {2 July 2010). 5 pages, 7 figure

A Complementary Resistive Switch-based Crossbar Array Adder

Redox-based resistive switching devices (ReRAM) are an emerging class of non-volatile storage elements suited for nanoscale memory applications. In terms of logic operations, ReRAM devices were suggested to be used as programmable interconnects, large-scale look-up tables or for sequential logic operations. However, without additional selector devices these approaches are not suited for use in large scale nanocrossbar memory arrays, which is the preferred architecture for ReRAM devices due to the minimum area consumption. To overcome this issue for the sequential logic approach, we recently introduced a novel concept, which is suited for passive crossbar arrays using complementary resistive switches (CRSs). CRS cells offer two high resistive storage states, and thus, parasitic sneak currents are efficiently avoided. However, until now the CRS-based logic-in-memory approach was only shown to be able to perform basic Boolean logic operations using a single CRS cell. In this paper, we introduce two multi-bit adder schemes using the CRS-based logic-in-memory approach. We proof the concepts by means of SPICE simulations using a dynamical memristive device model of a ReRAM cell. Finally, we show the advantages of our novel adder concept in terms of step count and number of devices in comparison to a recently published adder approach, which applies the conventional ReRAM-based sequential logic concept introduced by Borghetti et al.Comment: 12 pages, accepted for IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS), issue on Computing in Emerging Technologie

Impact: Linguistics in the real world

There is currently an emphasis in the funding of universities in the UK on the demonstrable impact of research. In this article we explore the work of the second generation of the Anglo-Scandinavian School, those linguists who were amongst the first to take the formal study of modern languages at university level out into the schools. We argue that their work is an excellent historical example of research into language having an impact in the real world, and we go on to argue that it was able to do so because the desire to make a difference was built into their research from the outset
