OBJECTIVE To determine the prevalence, severity and pattern of intestinal parasitic infestation in HIV-seropositive patients. METHODS A Cross-sectional study from January 2007 to December 2008.Patients were recruited from the HIV clinics of the hospital. Paired blood and single stool specimens were collected from each patient. The stool sample was investigated for intestinal parasites while t...

Conforming colorings naturally generalize many graph theory structures, including independent sets, vertex colorings, list colorings, H-colorings and adapted colorings. Given a multigraph G and a function F that assigns a forbidden ordered pair of colors to each edge e, we say a coloring C of the vertices is conforming to F if, for all e = (u, v), F (e) 6= (C(u), C(v)). We consider Markov chain...

AIM While the requirements for single-use gloves for staff protection are clearly defined, the conventional medical differentiation between "sterile surgical gloves" used during surgical procedures and "single-use medical gloves" used in non-sterile medical areas does not adequately define the different requirements in these two areas of use. Sterilization of single-use medical gloves is not pe...

MOTIVATION Recent technology platforms in proteomics and genomics produce count data for quantitative analysis. Previous works on statistical significance analysis for count data have mainly focused on the independent sample setting, which does not cover the case where pairs of measurements are taken from individual patients before and after treatment. This experimental setting requires paired ...

This paper considers the problem of multi-sample nonparametric comparison of counting processes with panel count data, which arise naturally when recurrent events are considered. Such data frequently occur in medical follow-up studies and reliability experiments, for example. For the problem considered, we construct two new classes of nonparametric test statistics based on the accumulated weigh...

A method for determining a representative count of a sample dependent on number of species is presented for application to various algal communities. Constant species curves are calculated as ejiciencj = (number of individuals number of species)/nurnber of individuals and diagrammed on a plot of eficiencj versus number of individuals counted. Eficiencj is deJined as the probability that a new s...

In this manuscript, we study the nonparametric k-sample test problem with panel count data. The asymptotic normality of a smooth functional of the nonparametric maximum pseudo-likelihood estimator (Wellner and Zhang, 2000) is established under some mild conditions. We construct a class of easy-to-implement nonparametric tests for comparing mean functions of k populations based on this asymptoti...
