Muon ID- Taking Care of Lower Momenta Muons

In the Muon package under study, the tracks are extrapolated using an algorithm which accounts for the magnetic field and the ionization (dE/dx). We improved the calculation of the field dependent term to increase the muon detection efficiency at lower momenta using a Runge-Kutta method. The muon identification and hadron separation in b-bbar jets is reported with the improved software. In the same framework, the utilization of the Kalman filter is introduced. The principle of the Kalman filter is described in some detail with the propagation matrix, with the Runge-Kutta term included, and the effect on low momenta single muons particles is described.Comment: PDF,5pages,2 Figures,1 Table,Presented at the 2005 International Linear Collider Physics and Detectors Workshop,Snowmass,Colorado,14-27 Aug. 2005, PSN1011 in the proceedin

Immigrants and the Community

First in a series based on the research project "Integrating the Needs of Immigrant Workers and Rural Communities," which attempts to inform New York communities about the nature and consequences of increasing immigrant settlement.Many upstate New York communities have experienced population loss and decline in the last decade. Increasing numbers of immigrants have settled in many of these communities, which poses possible community development challenges and opportunities. Because each community must address these issues in its own way, this report is intended to make communities aware of changes in their populations and highlight issues they may choose to address.USDA Fund for Rural America (grant #2001-36201-11283) and Cornell University Agricultural Experiment Station (grant #33452
