1. Overview We present a set of useful diagnostics for checking model assumptions and model fit for a type of mixed model for longitudinal data, random coefficient models. Because of the increasing use of complex sampling designs in longitudinal studies, there is a need for diagnostics that can be used with data with unequal probabilities of selection. In particular, the usual diagnostics, both...

This study compared two methods of assaying the 25-hydroxylated metabolites of cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2). A fully automated electrochemiluminescence assay from Roche Diagnostics and an HPLC based method from Chromsystems were used to measure vitamin D levels in surplus sera from 96 individuals, where the majority has the D2 form of the vitamin. Deming regressi...

Area: Diagnostics for future burning tokamak devices and stellarators. Benefit: An opportunity to develop compelling technology in the area of plasma diagnostics allowing internal field, n e and T e measurements on next step tokamaks and stellarators. Questions: 1) What can the US do in regards to ITER and DEMO to allow us to be an integral player, to play a bigger role? 2) Our importance withi...

An extensive set of diagnostics for linear regression models has been developed to handle nonsurvey data. The models and the sampling plans used for finite populations often entail stratification, clustering, and survey weights, which renders many of the standard diagnostics inappropriate. In this article we adapt some influence diagnostics that have been formulated for ordinary or weighted lea...

As the high-brightness electron beams become denser and reach sub-100 μm sizes, a resolution of the transverse profile diagnostics become an important issue. The applicability of the traditional scintillators as the diagnostics for most generic transverse properties of small dense beams is questionable. Recently, a YAG:Ce single crystal was used successfully, but studies indicated the presence ...

The author proposes some simple diagnostics for the assessment of the necessity of selected model terms in smoothing spline ANOVA models; the elimination of practically insignificant terms generally enhances the interpretability of the estimates, and sometimes may also have inferential implications. The diagnostics are derived from Kullback-Leibler geometry, and are illustrated in the settings ...

In recent years, the private and public sectors have increased investments in medical diagnostics for low- and middle-income countries (LMICs). Despite these investments, numerous barriers prevent the adoption of existing diagnostics and discourage the development and introduction of new diagnostics in LMICs. In the late 1990s, the global vaccine community had similar challenges, as vaccine cov...

The diagnostic system discussed in this paper provides an agent-based approach to advanced on-board diagnostics of operation and communication failures occurring in an electronic automotive system. To facilitate development and testing of agent-based automotive diagnostics, a software simulator of automotive electronics systems, also based on multi-agent technology, has been implemented, allowi...

liposomes have attracted great interest as efficient carriers for nutrients, drugs and other bioactive agents as well as ideal models for biological membranes. this article intends to provide an overview of liposomes and nanoliposomes definition as well as their properties and preparation methods. also it elaborates on various applications of nanoliposomes in nanotherapy including diagnostics, ...
