In the United States, medically underserved women carry a heavier burden of cancer incidence and mortality, yet are largely underrepresented in cancer prevention studies. My Body, My Test is a n observational cohort, multi-phase cervical cancer prevention study in North Carolina that recruited low-income women, aged 30–65 years and who had not undergone Pap testing in ≥ 4 years. Participants were offered home-based self-collection of cervico-vaginal samples for primary HPV testing. Here, we aimed to describe the recruitment strategies utilized by study staff, and the resulting recruitment and self-collection kit return rates for each specific recruitment strategy. Participants were recruited through different approaches: either direct (active, staff-effort intensive) or indirect (passive on the part of study staff). Of a total of 1,475 individuals screened for eligibility, 695 were eligible (47.1%) and 487 (70% of eligible) participants returned their self-collection kit. Small media recruitment resulted in the highest number of individuals found to be study eligible, with a relatively high self-collection kit return of 70%. In-clinic in-reach resulted in a lower number of study-eligible women, yet had the highest kit return rate (90%) among those sent kits. In contrast, 211 recruitment which resulted in the lowest kit return of 54%. Small media, word of mouth, and face-to-face outreach resulted in self-collection kit return rates ranging from 72 to 79%. The recruitment strategies undertaken by study staff support the continued study of reaching under-screened populations into cervical cancer prevention studies.

To fully characterize the luminosity performance of a linear collider, it is important to simulate the effects of ground motion as well as the beam-beam feedback and other stabilization systems planned to compensate for that motion. The linear collider simulation codes have recently been extended to include both ground motion models and stabilization systems to support the work of the International Linear Collider Technical Review Committee (TRC). This paper discusses the implementation details and the optimization strategies for interpulse beam-beam feedback.

The performance of various systems of the Next Linear Collider (NLC) have been studied in terms of ground motion using recently developed models. In particular, the performance of the beam delivery system is discussed. Plans to evaluate the operation of the main linac beam-based alignment and feedback systems are also outlined., Comment: Submitted to XX International Linac Conference

We report on the smallest vertical emittance achieved in single-bunch-mode operation of the ATF. The emittances were measured with a laser-wire beam-profile monitor installed in the damping ring. The bunch length and the momentum spread of the beam were also recorded under the same conditions. The smallest vertical rms emittance measured is 4 pm in the limit of zero current. It increases by a factor of 1.5 for a bunch intensity of 10^10 electrons. There are no discrepancies between the measured data and the calculations of intra-beam scattering.

Two general levels of productivity, since 1970, were previously identified for the Subareas 3+4 component of the northern shortfin squid (Illex illecebrosus) population based on trends in survey relative biomass indices and squid mean weight, as well as nominal catches (Rivard et al. 1998, Hendrickson 1999). A period of high productivity (1976-1981) occurred between two low productivity periods (1970-1975 and 1982-1999). During 2000, pre-fishery, July survey abundance and biomass indices for Subarea 4 were at the lowest level since 1970. Total catches in Subareas 3+4 remained low during 2000 (340 t) and were similar to those from 1999 (305 t). The mean weights of squid caught in the Division 4VWX July survey and the Subareas 5+6 autumn survey were the lowest in each time series. Based on these trends, the Subareas 3+4 stock component remained in a state of low productivity during 2000.
