Microarrays have become a routine tool for biomedical research. Data quality assessment is an essential part of the analysis, but it is still not easy to perform objectively or in an automated manner, and as a result it is often neglected. Here, we compared two strategies of array-level quality control using five publicly available microarray experiments: outlier removal and array weights. We a...

It is the position of American Association of Diabetes Educators (AADE) that all inpatient interdisciplinary teams include a diabetes educator to lead or support improvement efforts that affect patients hospitalized with diabetes or hyperglycemia. This not only encompasses patient and family education but education of interdisciplinary team members and achievement of diabetes-related organizati...

In overlay networks, both local and long-distance links appear as a single hop to a routing protocol. Traditional routing metrics (based on hop count or packet loss) fail to take the differences between such links into account. In this paper, we study a metric based on packet delay that has been designed to improve routing in overlay networks. We show a lightweight technique for measuring delay...

In this paper, we describe a modeling framework which allows us to reason about the social-cultural behavior of humans in interaction scenarios. The objective is to provide explanatory and predictive power to an agent or robot which either witnesses or participates in the interaction: why have the human agents behaved the way they are and what kind of behavior can I expect as an answer to certa...

Background Growing evidence shows that hospitals are increasingly employing physicians. Objective To examine changes in U.S. acute care hospitals that reported employment relationships with their physicians and to determine whether quality of care improved after the hospitals switched to this integration model. Design Retrospective cohort study of U.S. acute care hospitals between 2003 and ...

In this paper we study natural gradient approaches to blind separation of over-and under-complete mixtures. First we introduce Lie group structures on the mani-folds of the under-and over-complete mixture matrices respectively, and endow Riemannian metrics on the manifolds based on the property of Lie groups. Then we derive the natural gradients on the manifolds using the isometry of the Rieman...

The manufacturing organizations today are having a competition of supply chain versus supply chain. Existing research work fails to relate human metrics with supply chain performance. The authors intend to empirically assess the effects of human metrics on supply chain performance in the context of Indian manufacturing organizations. A rigorous literature review has identified 12 variables. The...

Image restoration or deconvolution of a blurred natural image is a mature research activity with a rich set of available techniques and algorithms, well-summarised in review articles, Banham & Katsaggelos (1997); Kundur & Hatzinakos (1996). Despite this history and volume of work, there is current research activity motivated by the desire to find yet superior methods to restore the ground truth...

Adaptive reflective surfaces have been a challenge for both electronic paper (e-paper) and biological organisms. Multiple colours, contrast, polarization, reflectance, diffusivity and texture must all be controlled simultaneously without optical losses in order to fully replicate the appearance of natural surfaces and vividly communicate information. This review merges the frontiers of knowledg...
