Estimates of population size for hidden and hard-to-reach individuals are of particular interest to health officials when health problems are concentrated in such populations. Efforts to derive these estimates are often frustrated by a range of factors including social stigma or an association with illegal activities that ordinarily preclude conventional survey strategies. This paper builds on ...

This report describes the cases of 2 patients with failed retrieval of an AngioGuard distal protection device after carotid stent placement with rescue retrieval by use of a vertebral catheter. An AngioGuard was deployed before carotid angioplasty and stent placement. Attempted removal of the device with the provided recapture sheath was unsuccessful. A 5F 120-cm vertebral catheter was used to ...

We observe multiply frustrated tunneling ionization-induced dissociation of the argon dimers by intense linearly polarized ultrashort laser pulses. By measuring the kinetic energy release and angular distribution of the Coulomb explosion of up to eightfold ionized argon dimers, we can trace the recapture of up to two electrons to Rydberg states of the highly charged compound at the end of the l...

The use of capture-recapture to estimate the residual faults in a software artifact has evolved as a promising method. However, the assumptions needed to make the estimates are not completely fulfilled in software development, leading to an underestimation of the residual fault content. Therefore, a method employing a filtering technique with an experience factor to improve the estimates of the...

The authors encourage an approach to personal exploration that attempts to recapture the person in the therapist. Person in the therapist training is aimed at helping therapists discover or recapture their own values, beliefs, and personal ethics. A personal approach to theory development and the practice of therapy is offered and discussed. Activities to re-capture the person in the therapist ...

The Varicella (chickenpox) Active Surveillance Project (VASP) has been conducting active surveillance since 1 January 1995 in the high desert community known as Antelope Valley, CA (population 300,000) among 300 public and private schools, daycares, and healthcare providers. Capture-recapture methods were applied to estimate reporting completeness for 1995 varicella incidence data and these wer...

The dependence of animal capture probabilities on auxiliary variables is an important practical problem which has not been considered when developing the statistical methodology of population estimation for capture-recapture and removal experiments. In this paper the linear logistic binary regression model is used to relate the probability of capture to continuous auxiliary variables. The auxil...
