Mixings, Lifetimes, Spectroscopy and Production of Heavy Flavor at the Tevatron

The Fermilab Tevatron offers unique opportunities to perform measurements of the heavier B hadrons that are not accessible at the Upsilon(4S) resonance. In this summary, we describe some recent heavy flavor results from the DO and CDF collaborations and discuss prospects for future measurements.Comment: To appear in Proceedings of the XXI International Symposium on lepton and Photon Interactions at High Energies, Fermilab, August 200

Electroweak and B Physics Results from the Fermilab Tevatron Collider

This writeup is an introduction to some of the experimental issues involved in performing electroweak and B physics measurements at the Fermilab Tevatron. In the electroweak sector, we discuss W and Z boson cross section measurements as well as the measurement of the mass of the W boson. For B physics, we discuss measurements of B^0/\bar{B^0} mixing and CP violation. This paper is geared towards nonexperts who are interested in understanding some of the issues and motivations for these measurements and how the measurements are carried out.Comment: 42 pages, presented at the 2000 SLAC Summer Institut

Searching for Doubly-Charged Higgs Bosons at Future Colliders

Doubly-charged Higgs bosons ($\Delta^{--}/\Delta^{++}$) appear in several extensions to the Standard Model and can be relatively light. We review the theoretical motivation for these states and present a study of the discovery reach in future runs of the Fermilab Tevatron for pair-produced doubly-charged Higgs bosons decaying to like-sign lepton pairs. We also comment on the discovery potential at other future colliders.Comment: 6 pages, full postscript file also available via anonymous ftp at ftp://ucdhep.ucdavis.edu/gunion/hmm_sm96.ps To appear in ``Proceedings of the 1996 DPF/DPB Summer Study on New Directions for High Energy Physics'

Parallel ELLPACK for Shared Memory Multiprocessors

This paper describes a parallel version of ELLPACK for shared memory multiprocessors. ELLPACK is a system for numerically solving elliptic PDEs. It consists of a very high level language for defining PDE problems and selecting methods of solution, and a library of approximately fifty problem solving modules. Earlier work considered three discretization modules (five point star, hodie, and hermite collocation), two linear system solution modules (linpack spd band and jacobi cg), and a triple module (hodie fft) which includes both discretization and solution, all for rectangular domains and simple boundary conditions. Here we describe parallel versions of six additional modules (hermite collocation, hodie helmholtz, five point star, band ge, sor, symmetric sor cg) for general boundary conditions and domains, and discuss modifications to the ELLPACK preprocessor, the tool that translates an ELLPACK "program" into FORTRAN

"Now all I care about is my future" - supporting the shift: framework for the effective resettlement of young people leaving custody: a summary

This document has been produced as part of the Beyond Youth Custody (BYC) programme, funded under the Big Lottery Fund’s Youth in Focus initiative. BYC has been designed to challenge, advance and promote better thinking in policy and practice for the effective and sustainable resettlement of young people after custody. The programme has published research reports, policy briefings and practitioner guidance on a number of key issues in resettlement including diversity, young people with background trauma, girls and young women, and engaging young people; all resources are available for download at www.beyondyouthcustody.net. The new framework presented here – which draws on findings from across the programme – proposes, for the first time internationally, a ‘theory of change’ for the sustainable re-entry of young people. This reconceptualisation of resettlement enables a better understanding of why practices previously shown by research to improve recidivism rates are effective. Consequently, the framework provides a new focus for resettlement services’ aims and objectives, and may be particularly useful as a common language for the inter-agency working that we know is essential when supporting young people. The framework has been designed as a resource for policy makers, decision makers, academics studying youth justice and anyone working with young people leaving custody. A visual representation of the framework outlined in this document can be found on the centre pages.

The Strategic Development of Irish Livestock Marts.

End of Project ReportA study of co-operative livestock marts revealed that cumulative marts turnover decreased by 26% from 1990 to 1999: Commission income as a percentage of turnover increased from 2% in 1990 to 3.2% in 1999. However operating expenses increased by 25% from 1990 to 1999. Operating expenses have since 1997, surpassed commision income, thus putting co-op marts in a collective loss making situation from their mart activities. However overall profit from co-op mart societies (including profit generated from all business activities) almost doubled between 1990 and 1999. While overall profitability of livestock marts societies has increased, twelve of thirty nine marts were in a loss making situation in 1999. Four of these marts have been in a permanent loss - making situation since 1990. All loss making societies in 1999 have little or no involvement in non-mart activities and almost all operate from just one site. In general, the large diversified societies are showing profitability. A number of strategic alternatives to deal with their situation were placed before mart executives. A diversification strategy is by far the most likely strategy to be adopted by marts for the future Most marts are unlikely to consider merging with other societies. Most marts have no plans to downsize and exit from the industry is not considered an option by any society. There is a recognition that there is an urgent need to rationalise the industry, but this strategy is likely to meet with a strong resistance from marts . A problem with rationalisation is that there are no incentives to make this strategy a reality. On the one hand, management would be reluctant to follow this approach, as it may be perceived to reflect badly on their own performance or may result in them being forced to seek alternative employment. On the other hand, the shareholders have little to gain and much to lose if the mart closes. Projections of past trends and impact of new policies would suggest continuing decline in turnover and profitability in the co-operative mart sector. Rationalisation is therefore absolutely essential. The industry cannot sustain the present number of marts. Diversification seems the most obvious option for the future of the industry. In general marts that have diversified are profitable and there is no reason why this trend cannot continue into the future

Body composition data from the rat subjects of Cosmos 1129 experiment K-316

The effects of 18.5 days of weightlessness on the body composition of young, growing, male laboratory rats were examined. Three groups of 5 rats each were examined. It is indicated that exposure of young, growing, male rats to 18.5 days of weightlessness produces: (1) no effect on the quantity of fat stored by the body; (2) a slight reduction in the quantity of fat free tissue laid down by the body; (3) a small reduction in the fraction of water contained by the fat free body mass; (4) a similar reduction in the fraction of water contained by the fat free skin and fat free carcass; (5) a shift in relative distribution of the total body water from skin to viscera; (6) a diminution in the fraction of extracellular water contained by the fat free body; (7) no effect on the fraction of total skeletal musculature contained by the fat free body, as indicated by body creatine content; (8) a sizeable reduction in the fraction of bone mineral contained by the fat free body, as calculated from body calcium content. The nature of the physiological changes induced by unloading from Earth gravity in the mammalian organism are illustrated
