Comparing the small sample performance of several variance estimators under competing risks
(John Wiley & Sons, Ltd., 2007-02-28)
We examine several variance estimators for cumulative incidence estimators that have been proposed over time, some of which are derived from asymptotic martingale or counting process theory, and some of which are developed ...
A Bayesian analysis of small n sequential multiple assignment randomized trials (snSMARTs)
(Wiley Periodicals, Inc.SIAM, 2018-11-20)
Meta‐analysis of gene‐environment interaction exploiting gene‐environment independence across multiple case‐control studies
(Wiley Periodicals, Inc.Springer Verlag, 2017-10-30)
Estimation for paired binomial data with application to radiation therapy
(John Wiley & Sons, Ltd., 2001-11-30)
We compare and contrast several different methods for estimating the effect of treatment when responses are paired binomial observations. The ratio of binomial probabilities is the parameter of interest, while the binomial ...
Primary rat hepatocyte culture on 3D nanofibrous polymer scaffolds for toxicology and pharmaceutical research
(Wiley Subscription Services, Inc., A Wiley Company, 2011-01)
Primary rat hepatocytes are a widely used experimental model to estimate drug metabolism and toxicity. In currently used two-dimensional (2D) cell culture systems, typical problems like morphological changes and the loss ...
Microprinted feeder cells guide embryonic stem cell fate
(Wiley Subscription Services, Inc., A Wiley Company, 2011-10)
We introduce a non‐contact approach to microprint multiple types of feeder cells in a microarray format using immiscible aqueous solutions of two biopolymers. Droplets of cell suspension in the denser aqueous phase are ...
Social security health insurance for the informal sector in Nicaragua: a randomized evaluation
(John Wiley & Sons, Ltd., 2010-09)
This article presents the results from an experimental evaluation of a voluntary health insurance program for informal sector workers in Nicaragua. Costs of the premiums as well as enrollment location were randomly allocated. ...
Training of the next generation of biostatisticians: a call to action in the U.S.
(John Wiley & Sons, Ltd., 2006-10-30)
Two workshops (2001, 2003) were held by the National Institutes of Health (NIH) to examine the need to train more biostatisticians in the U.S. to meet the increasing opportunities in the biomedical research enterprise. The ...
Cell affinity separations using magnetically stabilized fluidized beds: Erythrocyte subpopulation fractionation utilizing a lectin-magnetite support
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03-20)
A magnetically stabilized fluidized bed is used to separate erythrocyte subpopulations. Binding specificity was obtained by immobilizing the lectin Helix pomatia Agglutinin (HpA) or Griffonia simplicifolia I (GSI) onto ...
