OBJECTIVES Implanon was introduced in the UK in September 1999. We present here the results of our first 106 Implanon insertions, performed over a period of 18 months. The aims of the study were to study the clinical and demographic profile of Implanon users, to assess the continuation rates of Implanon in the local population, and to identify the reasons for removal. METHODS This was a case ...

OBJECTIVE To estimate 24-month continuation rates of all reversible contraceptive methods for women enrolled in the Contraceptive CHOICE Project. METHODS We analyzed 24-month data from the 9,256 participants enrolled in the Contraceptive CHOICE Project, a prospective observational cohort study that provides no-cost contraception to women in the St. Louis region. The project promoted the use o...

The transdermal contraceptive patch is an innovative contraceptive technology. The failure rate is quite low and has high continuation rate. The side effects and complications are not different from other hormonal contraceptives. This contraceptive method should be an alternative birth control technique for women.

Pricing of American options can be achieved by solving optimal stopping problems. This in turn can be done by computing so-called continuation values, which we represent as regression functions defined by the aid of a cash flow for the next few time periods. We use Monte Carlo to generate data and apply nonparametric least squares regression estimates to estimate the continuation values from th...

The conformal mapping of the Borel plane can be utilized for the analytic continuation of the Borel transform to the entire positive real semi-axis and is thus helpful in the resummation of divergent perturbation series in quantum field theory. We observe that the rate of convergence can be improved by the application of Padé approximants to the Borel transform expressed as a function of the co...

the problem of downward continuation of the gravity field from the earth’s surface to the reference ellipsoid arises from the fact that the solution to the boundary value problem for geoid determination without applying stokes formula is sought in terms of the disturbing potential on the ellipsoid but the gravity observations are only available on the earth’s surface. downward continuation is a...
