    Beyond the random phase approximation: Stimulated Brillouin backscatter for finite laser coherence times

    Full text link
    We develop a statistical theory of stimulated Brillouin backscatter (BSBS) of a spatially and temporally partially incoherent laser beam for laser fusion relevant plasma. We find a new collective regime of BSBS (CBSBS) with intensity threshold controlled by diffraction, an insensitive function of the laser coherence time, TcT_c, once light travel time during TcT_c exceeds a laser speckle length. The BSBS spatial gain rate is approximately the sum of that due to CBSBS, and a part which is independent of diffraction and varies linearly with TcT_c. We find that the bandwidth of KrF-laser-based fusion systems would be large enough to allow additional suppression of BSBS.Comment: 8 pages, 5 figures. arXiv admin note: substantial text overlap with arXiv:1105.209

    Health Insurance Coverage among Youth and Young Adults with Work Limitations

    This paper explores health insurance coverage trends for youth (age 15-18) and young adults (age 19-29) with work limitations using data from the Current Population Survey. In 2000 those in the young work-limited population were substantially more likely to have insurance coverage than their counterparts in the not work-limited population. They were much more likely to have public coverage and much less likely to have only private coverage. Insurance coverage for this population increased substantially between 1989 and 2000, in contrast to a decline for the not work-limited population. We discuss the probable contributions of policy reforms and the decline in employment of people with work limitations to these trends

    Trends in Outcomes for Young People with Disabilities: Are We Making Progress?

    This paper uses the Current Population Survey (CPS) from 1981-2000 to compare long term trends in socio-economic outcomes for youth (aged 15-21) and young adults (aged 22-29) with work limitations to those for youth and young adults without work limitations. We focus on the years 1988 and 1999: years that roughly correspond to the peaks of successive business cycles. We find that prevalence of work limitations declined for males but increased for females, mostly accounted for by growth for African American females. Despite a substantial reduction in the educational attainment gap between young adults with and without disabilities, gaps in employment, earnings, dependency on public programs and poverty widened substantially. These trends could be due to factors that determine whether individuals report themselves to be work-limited, factors that affect individual outcomes regardless of self-reported work limitation status, or both sets of factors
