Transcriptomics meta-analysis aims at re-using existing data to derive novel biological hypotheses, and is motivated by the public availability of a large number of independent studies. Current methods are based on breaking down studies into multiple comparisons between phenotypes (e.g. disease vs. healthy), based on the studies' experimental designs, followed by computing the overlap between t...

This paper re-visits the Bayesian approach to test its efficacy in optimally designing the classical (s, Q) inventory model. A heuristic search of the unstructured (s, Q) decision space finds that one can indeed make a decent start by the Bayesian approach—and keep total cost nearly optimally low throughout.

The present study aims to enhance the bioavailability of Blueberry by formulating it as nanosuspension. mainly consists ofanthocyanins which have strong antihyperlipidemic activity but suffers from low causes hindrances in itstherapeutic treat hyperlipidemia. Hence improve its bioavailability, nanosuspension blueberry was prepared. BoxBehnken design applied predict effect independent variables ...

When optimizing an accelerated degradation testing (ADT) plan, the initial values of unknown model parameters must be pre-specified. However, it is usually difficult to obtain the exact values, since many uncertainties are embedded in these parameters. Bayesian ADT optimal design was presented to address this problem by using prior distributions to capture these uncertainties. Nevertheless, whe...

Proper normalization of quantitative RT-PCR (qRT-PCR) data is a crucial component of gene -expression analysis. Although arbitrarily selected housekeeping genes have been used to normalize many published mRNA RT-PCR datasets, there is a growing awareness that such normalizers should be first validated empirically. The use of stable reference genes is particularly needed for qRT-PCR of microRNA ...

In this paper optimal experimental designs for inverse quadratic regression models are determined. We consider two different parameterizations of the model and investigate local optimal designs with respect to the c-, Dand Ecriteria, which reflect various aspects of the precision of the maximum likelihood estimator for the parameters in inverse quadratic regression models. In particular it is d...

Traditional factorial designs for evaluating interactions among chemicals in a mixture may be prohibitive when the number of chemicals is large. Using a mixture of chemicals with a fixed ratio (mixture ray) results in an economical design that allows estimation of additivity or nonadditive interaction for a mixture of interest. This methodology is extended easily to a mixture with a large numbe...

Array comparative genomic hybridization (aCGH) technology is commonly used to estimate genome-wide copy-number variation and to evaluate associations between copy number and disease. Although aCGH technology is well developed and there are numerous algorithms available for estimating copy number, little attention has been paid to the important issue of the statistical experimental design. Herei...

Conventional techniques for optimal experimental design are based on local sensitivity analysis to quantify parameter effects on the output. However, one of the key challenges for experimental design is that the local sensitivity is dependent on the unknown parameter values for a nonlinear model. This problem can be addressed if the sensitivity matrix, used in experimental design, could be comp...

BACKGROUND Experimental designs for evaluating knowledge translation (KT) interventions for professional behavior change can provide strong estimates of intervention effectiveness but offer limited insight how the intervention worked or not. Furthermore, trials provide little insight into the ways through which interventions lead to behavior change and how they are moderated by different facili...
