A previous study suggested the usefulness of pericardial fluid (PCF) and bone marrow aspirate (BMA) for the postmortem analysis of ethanol. The present study reviewed forensic autopsy cases (n = 2,983), which included 683 cases with the following positive toxicological findings, to reassess ethanol distribution and to investigate other gaseous and volatile substances in blood, PCF and BMA. Toxi...

OBJECTIVE Macrophage activation syndrome (MAS) is a well described, but purportedly uncommon manifestation of systemic juvenile idiopathic arthritis (SJIA). There is evidence to suggest that macrophage activation is integral to the pathogenesis of SJIA. Accordingly, many patients with SJIA may have evidence of mild MAS that is not appreciated clinically. We investigated the prevalence of occult...

INTRODUCTION Bone marrow examination is a useful investigative tool for the diagnosis of many hematological and nonhematological disorders. Bone marrow aspiration (BMA) provides information about the numerical and cytological features of marrow cells, whereas bone marrow trephine biopsies (BMB) provide excellent appreciation of spatial relationships between cells and of overall bone marrow stru...

The methodology of Bayesian Model Averaging (BMA) is applied for assessment of newborn brain maturity from sleep EEG. In theory this methodology provides the most accurate assessments of uncertainty in decisions. However, the existing BMA techniques have been shown providing biased assessments in the absence of some prior information enabling to explore model parameter space in details within a...

Butyl methacrylate (BMA)-ethylene dimethacrylate (EDMA)-methacrylic acid (MAA) and BMA-EDMA-2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) monolithic columns were prepared by varying the percentage of ionic monomers for capillary electrochromatography. Monolithic columns with a higher content of ionic monomers provided better column efficiency, and the performance of BMA-EDMA-MAA monoliths...

The low-energy characteristics of wireless sensor networks (WSNs) pose a great design challenge for MAC protocol design. Recent studies have proposed different clusterbased MAC protocols. In [1], we proposed an intra-cluster communication bit-map-assisted (BMA) MAC protocol for clusterbased WSNs. BMA is intended for event-driven applications, where sensor nodes transmit data to the cluster head...

Standard statistical practice ignores model uncertainty Data analysts typically select a model from some class of models and then proceed as if the selected model had generated the data This approach ignores the uncertainty in model selection leading to over con dent inferences and decisions that are more risky than one thinks they are Bayesian model averaging BMA provides a coherent mechanism ...

We compare Bayes Model Averaging, BMA, to a non-Bayes form of model averaging called stacking. In stacking, the weights are no longer posterior probabilities of models; they are obtained by a technique based on cross-validation. When the correct data generating model (DGM) is on the list of models under consideration BMA is never worse than stacking and often is demonstrably better, provided th...

Although Bayesian model averaging (BMA) is in principle the optimal method for combining learned models, it has received relatively little attention in the machine learning literature. This article describes an extensive empirical study of the application of BMA to rule induction. BMA is applied to a variety of tasks and compared with more ad hoc alternatives like bagging. In each case, BMA typ...

Trephine biopsy (TB) combined with bone marrow aspiration (BMA) is the most common method for evaluating bone marrow (BM) involvement in non-Hodgkin's lymphomas. Nevertheless, the role of TB in high-grade lymphomas remains controversial. We reviewed the results of 42 consecutive BMAs and TBs performed simultaneously in 29 patients with lymphoblastic lymphoma (LL) and small, non-cleaved cell lym...
